This helpers are not for general CR calculation, they are just for the
common case of the sign extended result of integer instructions if the
rc bit is set.
They must not be used by other instructions like cmp, so there is no
need to be as flexible.
cmpi shall compare two signed 32 bit values. The used difference a-b
may overflow and so the resulting 32 bit value can't represent it.
A correct way would be cr = s64(a) - s64(b) and it should be done in
this way in the JITs, but the Interpreter shall implement the most
readable way.
Also drops the now unused helper function.
The switch statements in these functions appear to get transformed into
an if..else chain on NVIDIA's OpenGL/Vulkan drivers, resulting in lower
performance than the D3D counterparts. Transforming the switch into a
binary tree of ifs can increase performance by up to 20%.
Since we don't want users to have to configure the region manually
and always enforce one automatically, we should fall back to a region
that was likely to be chosen by the user instead of always using
PAL whenever the title region cannot be detected.
Dolphin doesn't mess with installed NAND titles like the system menu,
so it is a reliable indicator of what region the user wants.
"Pad size" just doesn't make much sense. Let's go with "Buffer size"
instead, since the control for it is labeled "Buffer".
(Another possibility is "Pad buffer size", but I'm against that,
because we've stopped referring to controllers as "pads" in almost
all GUI strings.)
* Add missing Language setting loading/saving. This was added after the
original OnionConfig PR, which is why support for it was missing.
* Change MovieConfigLoader to reuse ConfigInfos. Less duplication.
* Extract MovieConfigLoader::Save into SaveToDTM. The DTM should use
the current config and not just the movie layer. This makes more
sense than just saving the movie layer, which may not always exist,
and also fixes a crash that would happen when creating a new
recording because the movie layer wouldn't exist in that case.
(Plus, having to get the loader from the layer and call ChangeDTM
on it manually is not very pretty.)
Not really used anywhere yet, but useful for not having to duplicate
config locations and for getting rid of conflicts when I get around
to rebase my Main.Core and Main.DSP porting PR.
Settings that come from the SYSCONF are now included in Dolphin's
config system as part of the base layer. They are handled in a
special way compared to other settings to make sure they are only
loaded from and saved to the SYSCONF (to avoid different, possibly
contradicting sources of truth).
This could cause the first branch of the bootucode procedure, which
takes its parameters from the AX registers, to run during the ROM init
sequence. Since the ROM doesn't set any of the AX registers, the values
aren't meaningful, and can cause bad DMA transfers and crashes.
This adds a WiiWad constructor that takes a BlobReader, so that the
class can be used with more than just files from the host filesystem.
Required for using WiiWad with WADs from update partitions.
Must be 9 characters at most; otherwise the serial number will be
rejected by SDK libraries, as there is a check to ensure the string
length is strictly lower than 10.
This was breaking Metroid Prime 2: Echoes’s scanner in some rooms, such
as the one in https://fifoci.dolphin-emu.org/dff/mp2-scanner/
It was found on Ivy Bridge on Mesa, the alpha value read back from the
EFB was off-by-4 in multiple objects, which was a conversion error
because int4() is equivalent to floor() and the value wasn’t always
higher.
The casts to u32* are technically undefined behavior. The u8* cast is
left, as char/unsigned char is exempted from this rule to allow for
bvtewise inspection of objects (and this is what s8/u8 are typedefs of
on platforms we support).
Writing to 0x60 does actually not "init exception[s]" or anything like
that. Not at all. Rather, it *breaks* a check in Nintendo's SDK, which
makes it fail to realise that the hook hasn't been set up.
This prevents the SDK initialisation routines from writing the rest of
the hook instructions (total: 0x20 bytes), which in turn causes an
anti-piracy check to fail in some Ubisoft games (including Tintin).
Dolphin can be really amazing sometimes.
No clue where people got the 0 value from, or why it's labelled as
"time". As far as I can tell, it is always set to 0xffffffff by
official NAND titles, including the system menu.
It's not specific to WADs. The BS2 emulation boot code will also need
to update the state file.
Move the struct to Boot and add a helper function that will handle
reading + computing the checksum + writing the state file.
Sentret_C posted this comment on Transifex recently:
"What Dolphin refers to as "Table View" and "List View" are
similar to "List View" and "Grid View" in Steam, and I think
the Steam names describe them better."
I agree with that, so here's a commit that changes the names.
This is supposed to get efb2tex to the same texture as efb2ram, by applying the related efb copies as updates after each other, in the order of their creation.
Improve bookkeeping around formats. Hopefully make code less confusing.
- Rename TlutFormat -> TLUTFormat to follow conventions.
- Use enum classes to prevent using a Texture format where an EFB Copy format
is expected or vice-versa.
- Use common EFBCopyFormat names regardless of depth and YUV configurations.
This way it allows us to use surfaceless contexts in EGL/GLX. It also
ensures that the shared context shares a similar setup to the main
context's framebuffer, potentially reducing the number of variants a
driver needs to generate.
Previously we were falling back to an earlier version of the compiler.
The older version cannot compile our ubershaders without various
graphical issues.
When recording during netplay, the stop message was only sent after you
have chosen a filename for the replay, causing the other player(s)
to freeze for a few seconds. This takes care of the annoyance.
There were two problems with this:
1. If the starting offset was beyond the end of the disc,
we would dereference an invalid iterator.
2. The data beyond the end of the disc was non-deterministic.
Having DiscContents with size 0 would mean that some DiscContents
might not get added to the std::set because of them comparing
identically to another DiscContent.
This replaces an older piece of code in WriteDirectory that ensures
that no two files have the same starting offset. (We now care about
the ending offset, not the starting offset. The new solution both
ensures that no two files have the same ending offset and that no
two files have the same starting offset.)
For instance, we don't want to show TGC files that might be
inside the /files/ directory of a GameCube DirectoryBlob,
and we don't want to show the /sys/main.dol files for extra
partitions of Wii DirectoryBlobs.
Now it's clearer that SetDOL depends on SetApploader
and BuildFST depends on SetDOL.
As a side note, we now load the DOL even if there's
no apploader. (I don't think it matters whether we
do it, but it was easier to implement this way.)
This lets VolumeDirectory/DirectoryBlob skip implementing
various volume functions like GetGameID, GetBanner, etc.
It also lets us view extracted discs in the game list.
This ends up breaking the boot process for Wii
DirectoryBlobs due to workarounds being removed from the
boot process, but that will be fixed later by adding
proper DirectoryBlob support for things like TMDs.
We now expect the directories to be laid out in a certain
format (based on the format that WIT uses) instead of requiring
the user to set the DVD root and apploader path settings.
This is useful for blob types that store Wii data unencrypted
(such as WIA and discs extracted to directories) so that
we don't have to waste CPU time encrypting in the blob code
just to decrypt right afterwards in the volume code.
The old approach to detecting DOL/ELF files doesn't fit
with the new way of implementing extracted discs.
The game list is already doing it in a way that's similar
to the approach that this commit uses.
The Config::AddLoadLayer functions call Load on the layer
explicitly, but Load is already called in the constructor,
so they'd cause the loader's Load function to be called twice,
which is potentially expensive considering we have to read an INI
from the host filesystem.
This commit removes the Config::AddLoadLayer functions because
they don't appear to be necessary.
This was mainly included for debugging, but could end up being confusing
for users, as well as polluting the GL program cache with a mix of uber
and specialized shaders if the option was changed.
On Windows, File::GetTempFilenameForAtomicWrite returns a path
somewhere in C:\Users\XXX\AppData\Local\Temp\{UUID here}\
in which all writes just fail.
Just use the SYSCONF path + ".tmp" for the temporary file name.
These vertex formats enable all attributes. Inactive attributes are set
to offset=0, and the smallest type possible. This "optimization" stops
the NV compiler from generating variants of vertex shaders.
This add support for SD protocol 2 while staying compatible with protocol 1.01.
Most of this is quite hacky, but it seems to be working well.
The original implementation was quite confusing, so I didn't touch most of the stuff I did not understand.
This makes the EGL interface select OpenGL|ES contexts over "desktop"
OpenGL ones.
Possibly not useful for anyone outside my own debugging, but you never
know
It's not particularily useful to list the platform here,
and these kinds of messages that use words as parameters
are more likely to be mistranslated than the average string.
Same as the previous commit, except I'm copying strings
in the other direction because the DolphinWX variants
of these strings could use some improvement.
The spec says it should have an EXT not OES suffix, as it's enabled as
an interaction with GL_EXT_multi_draw_arrays.
On some drivers GetProcAddress() returns NULL, which causes the
GLExtensions init to fail
This 'happened' to work if GetProcAddress() doesn't return NULL on missing
functions (as allowed in EGL) - as the function appears to never be called so
this would not have been noticed.
Mesa also (incorrectly?) exports the EXT version, so this would all
happen to work there, but appears to be contrary to the spec.
This invalid prefix even ended up in the upstream khronos registry, the
issue was reported here:
https://github.com/KhronosGroup/OpenGL-Registry/issues/81
The section is 0x461 bytes long, not 0x460. The config data is also now
initialised to zero to avoid garbage being written to the SYSCONF.
Because our handling has been wrong forever, we discard older BT.DINF
section backups as using them would result in the section being the
wrong size / incomplete again.
It turns out that the last byte of array entries isn't unused (as we
thought); instead, it looks like it's actually part of the main data,
and the length stored next to the name is in fact the length minus one.
Getting it wrong and always storing a null byte in there won't affect
most entries (since the last byte is zeroed most of the time), except:
- IPL.NIK: the length is stored in the last byte, and it must be kept.
- BT.DINF: u8 unknown[0x45] should be another Bluetooth device entry.
- Possibly other unknown affected entries.
I don't know who thought it would be a good idea to put the Wiimote
connect code as part of the Host interface, and have that called
from both the UI code and the core. And then hack around it by having
"force connect" events whenever Host_ConnectWiimote is called
from the core...
BluetoothEmu had its own bdaddr_t type which is a old style C struct
and typedef, which makes comparisons and copies a bit ugly.
On the other hand, BTReal had its own btaddr_t type using std::array.
To make things very slightly nicer, this commit changes the Bluetooth
code to use a single type (std::array<u8, 6>) for all BT addresses.
Imports/exports don't always use the title key. Exporting a title and
importing it back uses the PRNG key (aka backup key handle or key #5),
not the title key (at all).
To make things even more fun, some versions of IOS have a bug that
causes it to use a zeroed key instead of the PRNG key. When Nintendo
decided to fix it, they added checks to keep using the zeroed key only
in affected titles to avoid making existing exports useless.
(Thanks to tueidj for drawing my attention to this.
I missed this edge case during the initial implementation.)
This commit implements these checks so we are using the correct key
in all of these cases.
We now also use IOSC for decryption/encryption since built-in key
handles are used. And we now reject any invalid common key index,
just like ES.
Core::PauseAndLock requires all calls to it to be balanced, like this:
const bool was_unpaused = Core::PauseAndLock(true);
// do stuff on the CPU thread
Core::PauseAndLock(false, was_unpaused);
Aside from being a bit cumbersome, it turns out all callers really
don't need to know about was_unpaused at all. They just need to do
something on the CPU thread safely, including locking/unlocking.
So this commit replaces Core::PauseAndLock with a function that
makes both the purpose and the scope of what is being run on the
CPU thread visually clear. This makes it harder to accidentally run
something on the wrong thread, or forget the second call to
PauseAndLock to unpause, or forget that it needs to be passed
was_unpaused at the end.
We also don't need comments to indicate code X is being run on the
CPU thread anymore, as the function name makes it obvious.
The region mismatch check that we used can give false positives.
Skipping the check won't lead to any harm - games will ignore
save files that have a non-matching fourth game ID character.
According to http://scanlines16.com/en/blog-3/retro-gaming/game-cube/gamecube-korean-master-list/,
Korean GC releases use the following country codes:
- E or W for games in English
- K for games in Korean
- Unknown value for games in Japanese (my guess is that they might
have made the discs bit-for-bit identical to Japanese releases
because the regions of these games are already set to NTSC-J)
As far as I know, the GC has no Taiwanese releases, which is what
the W country code is used for on the Wii. But I could be wrong.
A small note: The country_byte == 'K' check in the code isn't
actually necessary as long as RegionSwitchGC returns NTSC_J
for 'K', but I thought it would be better to not rely on that.
The county code isn't 100% reliable for detecting the region.
For instance, some games released in Korea have the country
code E even though they're region-locked to NTSC-J consoles.
This commit makes the GC disc region detection match the Wii
disc region detection (apart from the region value being in
a different place on the disc).
Showing the Wii remote connection status leads to inconsistent UX,
because we don't do anything like that for GameCube controllers
or with Bluetooth passthrough.
It's also questionable how useful it is given that:
* it doesn't print the number of connected remotes, just that one
remote is connected, connecting or not connected, so the only info
it provides is actually wrong when using multiple remotes;
* this user-facing feature is actually broken in master and no one has
complained AFAIK, which means people don't really rely on it;
* the status bar isn't visible most of the time unless the user is
using render to main or deliberately keeping the main window's
status bar visible by moving the render window and they're not too
far away from their screen;
* emulated Wii remotes now reconnect on input, which means that there
is less of a need to actually know at all times whether a remote
is connected, since pressing any button will reconnect it and provide
immediate, visible feedback via OSD messages and the Wii remote
pointer appearing.
Rather than returning 0 / not creating an expected SI interrupt. You can
test this by running VBA-M in a debugger and stopping it while it's
connected to Dolphin: on current master, Dolphin will freeze-up until it
gets a response. With this PR, Dolphin will gracefully disconnect the device, and reconnect if it starts responding again.
Tracking a buffer's size manually and storing it under a name that
does not make it obvious it is related to the buffer is really... meh.
Also gets rid of the need to manually manage its capacity and
new/delete an array.
This commit merges the import and export contexts into a single context
because this is what IOS does, which means we can only reproduce its
behaviour correctly if we use a single context for both operations.
The other reason is that having two separate and very similar structs
is not really a good idea.
While working on this commit, I was notified that our handling of
ImportTmd/ExportTitleInit is not correct. In particular, we always use
the title key for both importing and exporting, which is wrong. To make
this easier to fix in a follow-up PR, the context now also has a title
key field, just like ES. This also lets us avoid computing it every
single time in ImportContentDone.
Allows them to be reused easily. Still a bit too much duplicated code
in my opinion (OpenContent/SeekContent/ReadContent should just call
FS code), but this is a start.
I think I do not need to explain why hardcoding space usage for two
random directories when we can calculate it and when IOS doesn't
actually do that is wrong.
There are some cases where overriding the opening.bnr names
isn't desirable, such as when someone has several modded
versions of a game that differ in names but not game IDs.
This was causing Dolphin to always save "WriteToWindow = False". Instead
of disabling logging to the window (a config value), tell LogManager
that there's no window to log to (a runtime state).
This is a remake of https://github.com/dolphin-emu/dolphin/pull/3749
Full credit goes to phire.
Old message:
"If none of the texture registers have changed and TMEM hasn't been invalidated or changed in other ways, we can blindly reuse the old texture cache entries without rehashing.
Not only does this fix the bloom effect in Spyro: A Hero's Tail (The game abused texture cache) but it will also provide speedups for other games which use the same texture over multiple draw calls, especially when safe texture cache is in use."
Changed the pr per phire's instructions to only return the current texture(s) if none of the texture registers were changed. If any texture register was changed, fall back to the default hashing and rebuilding textures from memory.
The actual problem was combining the values from the date and time
pickers incorrectly. The uninteresting parts of the returned wxDateTime
need to be ignored and the WX documentation says so for the time picker.
I also cleaned up the handling of both widgets a bit, removing redundant
member variables in the process, in order to not risk correctness.
It's a bit confusing to get a yes/no dialogue box without any indication
of what yes or no will do in this situation, so add a short explanatory
sentence.
Only remaining issue is that clicking on the titlebar of the window, to give it focus, is already interpreted as input. But clicking on the window in the task bar, or using alt tab works to get back, without causing an input event.
Changes:
- `ShowDevelopmentWarning` is now under the '[Interface]' group in
Dolphin.ini, with other interface-related settings. So, whoever uses
DolphinQt will have to edit that manually again. Sorry!
- Game search paths and the last file are now shared properly with
DolphinWX
- Qt-only preferences like "Preferred View: list/table" are now
stored using the platform's native settings storage, rather than in
UI.ini
struct GekkoOPTemplate was implemented differently in different
compilation units, which breaks the ODR and could end up causing issues
as symbols exported from one compilation unit could end up being used by
another even if they have different implementations.
This puts them in an anonymous namespace, restricting any generated
symbols to the single compilation unit.
Some code was calling more than one of these functions in a row
(in particular, FileUtil.cpp itself did it a lot...), which is
a waste since it's possible to call stat a single time and then
read all three values from the stat struct. This commit adds a
File::FileInfo class that calls stat once on construction and
then lets Exists/IsDirectory/GetSize be executed very quickly.
The performance improvement mostly matters for functions that
can be handling a lot of files, such as File::ScanDirectoryTree.
I've also done some cleanup in code that uses these functions.
For instance, some code had checks like !Exists() || !IsDirectory(),
which is functionally equivalent to !IsDirectory(), and some
code was using File::GetSize even though there was an IOFile
object that the code could call GetSize on.
The MonoSpaceFont of the LogWindow was using a Windows native way to
specify a font name.
Now it's using wxFONTFAMILY_TELETYPE.
On Win32 it will additionally request the specific font name "Consolas",
so it doesn't use ugly "Courier New". I pilfered that specialization
from Source/Core/DolphinWX/Cheats/ARCodeAddEdit.cpp.
Before, if you extracted a directory like /map/Final/Release/,
Dolphin would create the nested folders map, Final and Release
in the output directory and put the files in Release instead of
just putting the files directly in the output directory.
While setting up a proper NAND for Wii emulation has become much easier
now that disc and online system updates work, they still require users
to have a recent disc game, certificates extracted from IOS or a NAND
dump for online updates to work and to really get all system titles.
This commit adds the ability to do an online update right from
Dolphin itself, which solves that usability issue.
Allows reusing the WAD import logic more easily, whereas UICommon
code can only be used from UICommon and UI.
And managing what's on the NAND is the Core's responsability, not UI.
It didn't work when there were non-ASCII characters
in the directories argument, but it worked fine with
non-ASCII characters in names of found files and folders.
* IOS: WiiRoot shutdown was moved to HW.
* Movie: Don't call UpdateWantDeterminism() if we're not running yet,
because this will automatically be done during the boot process.
Not doing this will result in two NANDs being created.
This is larger than I thought I would be, but unfortunately it's quite
hard to split fixes like this when the handling is wrong in tons of
different places.
The content table is limited in size. It can only hold 16 entries.
Three consequences:
* Since the table cannot grow indefinitely, instead of using a std::map
we use a std::array as we should.
* Remove a hack where the CFD was cleared back to 0 on IPC close (wtf?)
* The CFD now doesn't keep increasing to infinity. It's unknown if this
would fix anything at all, but some issues in the past were caused
by CFDs being excessively large.
Other minor changes:
* Simplify save state logic.
* Keep track of the UID like ES does. Not sure how useful this is, but
we can do this very easily so why not.
* Remove the guesswork and use the actual error codes.
* Add more error checking to make Dolphin less likely to crash.
Something that should be done in the future: deduplicate the filesystem
logic. Something that takes one line in the actual ES code takes
10+ lines in our implementation... while duplicating the FS logic...
This will likely harder to fix though, so I'm leaving that
for another time.
It seems to make no difference besides allowing lower latencies and more
stability on hardware OpenAL cards. Maybe the Wait() call waits for too
long, causing buffers underruns.
Before these changes each value of latency were actually 5ms, with a
minimum latency of ~10 ms. If it was set to 4 ms on the UI, the actual
latency was 10 + 5 * 4 = 30 ms.
Now 30 ms on the UI means 30 ms on the backend.
c5fa470 made the extension check discard directories, but
only in the new code that currently only is used on Windows.
Let's add an equivalent check in the old code so that the
behavior is consistent across platforms.
This seems like an oversight in the old code, because
what's the point of loading user files if the titles
in them are going to be ignored for nearly all games?
This commit fixes the issue by making the first LoadMap
variant not overwrite entries and making the constructor
do everything in the opposite order. An alternative solution
would be to make the second LoadMap variant overwrite entries.
This fixes the global-static fifo object causing infinite hangs in some
cases. Notably, failure to initialize a graphics backend would result in
BlockingLoop::Prepare being called but never executing Run(), leaving the
object in a bad state.
The sanity check runs *before* finalising the import, so at that time
the whole title directory is still in /import and not in /title.
This means we should check for contents there, not in /title. Whoops.
The efficient function (that is nearly the same as
https://graphics.stanford.edu/~seander/bithacks.html#DetermineIfPowerOf2)
replaces one loop based instance (which also reused the xx variable
afterwards, whereas it should have used htabmask instead) and one
instance using the population count a.k.a. Hamming weigth.
This one verifies bitmasks where low bits are set to 1 (hence the name).
Any stray 0 among the lower ones or any stray 1 among the higher zeros
renders the mask invalid.
The edge cases of all zeros and all ones are considered valid masks.
It uses an efficient implementation. It's the counterpart of
https://graphics.stanford.edu/~seander/bithacks.html#DetermineIfPowerOf2
Simpler, and puts the call to CheckIntegrity right where it should be,
instead of being hidden somewhere in a thread class.
This also makes it more obvious what we're getting from the async task.
Oh, and coincidentally, this fixes a random crash that could occur
during the check. I'm not sure why.
This adds a check to ImportTitleDone to make sure all required contents
that are listed in the TMD have been imported before allowing to finish
the import. Not checking for this could allow titles to be left in an
inconsistent state.
There seems to be a race condition between a peripheral device
connecting to the bluetooth controller and it being ready to use.
It's very short and it depends upon the controller, some appear to
connect synchronously and block until the device is ready, others
report the device upon discovery but do not allow communication straight
away. I don't know which is the correct behaviour, or whether it depends
on the peripheral, controller or both. Anyway, Dolphin waits for a
remote to appear and immediately attempts to open the communication
channels, this can fail because the device isn't ready yet, delay, try
again, and it works.
There are other (unlikely) chances the device is busy at random
moments after this initial race condition so it loops around try to
reconnect.
This was inspired by an earlier patch, see here:
https://bugs.dolphin-emu.org/issues/5997#note-20
I can confirm that it works perfectly for me on a bluetooth
controller where otherwise it's impossible to connect (Dell 380
Bluetooth 4.0).
So, a FifoRecorder instance is instantiated as a file-local variable and
used as a singleton (ugh). Most users likely don't regularly use the
FIFO player/FIFO recorder, so this is kind of a substantial waste of
memory.
FifoRecorder's internal RAM and ExRAM vectors are 33554432 and 67108864
bytes respectively, which is around 100.66MB in total.
Just on the game list view on a clean build with nothing loaded, this
knocks debug build memory usage down from ~232.4MB to ~137.5MB, and
release build memory usage down from ~101MB to ~5.7MB.
The GameCube IPL sounds the same when using the free ROM as it does when
using the official ROM (and in Audacity, I couldn't visually distinguish
between the waveforms). It has a reference to an unimplemented function
at 0x8644 which seems to only be used in an inlined version of the CARD
ucode.
This allows the user to go through the Wii Menu first boot setup
screen when they launch the System Menu for the first time.
Most useful on a clean profile, after doing a full system update,
to configure settings like the console country.
This rewrites the SysConf code for several reasons:
* Modernising the SysConf class. The naming was entirely cleaned up.
constexpr for constants.
* Exposing less stuff in the header.
* Probably less efficient parsing and writing logic, but much simpler
to understand and use in my opinion. No more hardcoded offsets.
No more duplicated code for the initial SYSCONF generation.
* More flexibility. It is now possible to add and remove entries,
since we rebuild the file. This allows us to stop spamming
"section not found" panic alerts; we can now use and insert
default entries.
On a real Wii, the title list is not in any particular order. However,
because of how the flash filesystem works, titles such as 1-2 are
*never* in the first position. We must keep this behaviour, or some
versions of the System Menu may break.
Will be used from several functions to verify the signatures for
different containers (TMDs, tickets, device signed blobs).
An option was added to disable signature checks, because that could be
useful for people trying to import unsigned stuff.
stat() returns an error code in errno on both POSIX compliant
platforms and Windows.
This means we should always use errno instead of GetLastErrorMsg
which uses GetLastError() (Win32) on Windows.
POSIX allows one or more trailing slashes for directories.
From POSIX.1-2008, section 3.271 (Base Definitions / Pathname):
> A pathname can optionally contain one or more trailing <slash>
> characters. Multiple successive <slash> characters are considered to
> be the same as one <slash>, except for the case of exactly two
> leading <slash> characters.
On Windows, the extra trailing slashes are ignored for directories too.
This makes it possible to catch errors earlier so that file systems
simply fail to load instead of behaving oddly. It also makes it possible
to check for errors that weren't checkable before, like the end of a
directory being after the end of the parent directory.
Instead of expecting callers to know how the size of directory file infos
relates to which files are in which directories, filesystems now offer a
GetRoot() method, and file infos offer a way to get their children. As
a bonus, m_FileInfoVector no longer has to be created and kept around
in RAM. Only the file info objects that actually are used are created.
Not initializing until the filesystem is used is good when
a filesystem is constructed and then never used, but nobody does that.
This simplifies the code a little and lets all methods be const.
Instead of using lots of small scattered reads to read the FST,
only one big read is used, which is more efficient.
This also means that the FST only allocates memory once and stores all
strings close to each other - good for the CPU cache. The file info
objects use pointers to this FST memory of containing data themselves.
Keeping around the big m_FileInfoVector containing objects with only
pointers is a bit unnecessary, but that will be fixed soon.
Instead of calling GetPathFromFSTOffset for every file info, FindFileInfo
now only looks at names in directories that are included in the path.
For the common case of searching for "opening.bnr", this means that
only root-level files and directories have to be searched through.
Some callers already have the file info, making the relatively slow
FindFileInfo calls unnecessary. Callers that didn't have the file info
will now need to call FindFileInfo on their own.
Some callers (i.e. ISOProperties) don't want the full path, so giving them
it is unnecessary. Those that do want it can use GetPathFromFSTOffset.
Not storing full paths everywhere also saves a small bit of RAM and is
necessary for a later commit. The code isn't especially pretty right now
(callers need to use FST offsets...) but it'll become better later.
GC/Wii filesystem internals shouldn't be exposed to other classes.
This change isn't especially useful by itself, but it opens up the
way for some neat stuff in the following commits.
Too much boilerplate that is duplicated if we use curl directly.
Let's add a simple wrapper class that hides the implementation details
and just allows to simply make HTTP requests and get responses.
Makes it slightly less likely to forget a check and end up doing an
out-of-bounds access. Also makes it obvious that we *are* indeed
checking whether the handle is valid, instead of hiding it in
HasOwnership (which won't handle the root key handle case properly).
This code hadn't been touched since 2010. Nowadays, the panic alert
setting is loaded by ConfigManager and applied in UICommon.
VideoConfig has no business messing with it.
I don't see why we need to call ShutdownWiiRoot on InitializeWiiRoot.
Also, atexit? Really? Not only is this unnecessary, it will also cause
ShutdownWiiRoot to be called twice in rapid succession for no reason.
The config must only be restored after the HW has shut down, not while
it is still running, because the HW can still query the config, which
can lead to inconsistent states.
This fixes WiiRoot not being able to copy back saves on shutdown.
This ioctlv is used to get an IOSC decrypt handle for a title.
It is known to be used internally by the WFS modules, but it can also
be used from the PPC under some conditions.
Brings us down to 2 essentially unimplementable ioctlvs (syscalls which
seem to return kernel thread priorities...), and 1 known but
unimplemented ioctlv (VerifySign).
In the future, NAND filesystem access will be limited to one IOS
instance, for safety reasons and to make it possible to consider
supporting NAND images. This means that any code accessing the NAND
filesystem must go through the FS device, both for code that is
external to IOS and internal.
Because we don't want to introduce any singleton, this requires
internal IOS code that needs NAND access to be part of an IOS device
class, so they can access the FS device easily.
Making some of the internal ES implementation functions member
functions also prevents them from being (mis)used outside of IOS,
since they cannot be called everywhere anymore.
OpenALStream was querying the backend for AL_EXT_float32 support (which
suceeds), but AL_FORMAT_STEREO_FLOAT32 was defined incorrectly.
Also changes OpenALStream to query for AL_EXT_MCFORMATS (multichannel
support) rather than hard-coding that it doesn't work on macOS.
They have been broken since 2 years and no one has noticed,
which shows that no one really cares.
And it's arguable whether showing the CPU info is really useful.
I don't see any reason to disable loading the IPL if bHLE_BS2 is
disabled. bHLE_BS2 should only cause us not to run the IPL, but not
skip loading it in the first place. More importantly, without always
loading it, this causes issues when trying to launch only the GC IPL
while having bHLE_BS2 = false.
They're essentially the same. To achieve this, this commit unifies
DolReader and ElfReader into a common interface for boot executable
readers, so the only remaining difference between ELF and DOL is
how which volume is inserted.
* Move out boot parameters to a separate struct, which is not part
of SConfig/ConfigManager because there is no reason for it to
be there.
* Move out file name parsing and constructing the appropriate params
from paths to a separate function that does that, and only that.
* For every different boot type we support, add a proper struct with
only the required parameters, with descriptive names and use
std::variant to only store what we need.
* Clean up the bHLE_BS2 stuff which made no sense sometimes. Now
instead of using bHLE_BS2 for two different things, both for storing
the user config setting and as a runtime boot parameter,
we simply replace the Disc boot params with BootParameters::IPL.
* Const correctness so it's clear what can or cannot update the config.
* Drop unused parameters and unneeded checks.
* Make a few checks a lot more concise. (Looking at you, extension
checks for disc images.)
* Remove a mildly terrible workaround where we needed to pass an empty
string in order to boot the GC IPL without any game inserted.
(Not required anymore thanks to std::variant and std::optional.)
The motivation for this are multiple: cleaning up and being able to add
support for booting an installed NAND title. Without this change, it'd
be pretty much impossible to implement that.
Also, using std::visit with std::variant makes the compiler do
additional type checks: now we're guaranteed that the boot code will
handle all boot types and no invalid boot type will be possible.
I didn't know better back then, but the boot type is only supposed to
be used for the actual boot params. It shouldn't be used or changed
after booting.
You may want to read the PR #2047 comments before reading this.
Dolphin attempts to support an unencrypted type of Wii discs
that apparently is identified by a 4-byte integer at 0x60
being non-zero. I don't know what discs (if any) would be
using that format, so I haven't been able to test Dolphin's
support for it, but it has probably been broken for a while.
The old implementation is very short but also strange.
In CreateVolumeFromFilename, we read a 4-byte integer from
0x60, and if it's non-zero, we create a CVolumeGC object
instead of a CVolumeWiiCrypted object. This might seem like
it makes no sense, but it presumably worked in the past
because IsVolumeWiiDisc used to check the volume type by
reading the magic word for Wii straight from the disc,
meaning that CVolumeGC objects representing unencrypted Wii
discs would be treated as Wii discs by pretty much all of
Dolphin's code except for the volume implementation code.
(It wasn't possible to simply use CVolumeWiiCrypted, because
that class only handled encrypted discs, like the name says.)
However, that stopped working as intended because of ace0607.
And furthermore, bb93336 made it even more broken by making
parts of Dolphin expect that data read from Wii discs needed
to be decrypted (rather than the volume implementation
implicitly deciding whether to decrypt when Read was called).
Disclaimer: Like I said before, I haven't been able to test
any of this because I don't have any discs that use this
unencrypted Wii disc format, so this is all theoretical.
Later, PR #2047 tried to remove Dolphin's support for
the unencrypted Wii disc format because seemingly no
discs used it, but the PR got closed without being merged.
At the end of that PR, I said that I would make a new PR
with a better implementation for the format after PR #2353
was merged. Now that PR #2353 is merged (two years later...)
and PR #5521 is merged, the new implementation was easy to
make, and here it is!
Untested.
Normal users don't care about it. In fact, people care so
little about it that the Wii implementation of it was broken
starting from when it was implemented (eb65601) to 7 years
later (e0a47c1), apparently without anyone reporting it.
- coef: Explicitly set 23 different values that are used by GBA UCode,
and tweaked overall parameters to more closely match those 23 values.
- irom: Moved a few functions to their proper places, updated BootUCode
to configure DMA transfers using AX registers as well as IX registers
(the GBA UCode uses this to do two sequential transfers in one call),
and added partial functions used by GBA UCode.
All functions were reverse-engineered solely based off of observed
effects on the virtual machine: register states before-and-after, dmem
interactions, and DMA transfers. The specific coefficients were observed
being read from dmem, and must be exactly those values to function
properly. I have no knowledge of how the official ROM implements these
functions, or how it is implemented overall.
Tested with The Legend of Zelda: Four Swords Adventures, Final Fantasy
Crystal Chronicles, and Billy Hatcher and the Giant Egg (to download
ChuChu Rocket!).
`P_REG1C` had the same value as `P_ACCL`, so was causing spurious errors
when used with ACCM registers. Gcdsptool (which calls this `P_ACCLM`)
gives it the value `P_REG | 0x1c10` instead, and handles errors in the
same block as other REG## enums.
This makes the interface slightly cleaner and a bit more consistent
with the other getters. Still not fully the same, since the others
don't really handle failures with std::optional; but at least the
value is returned by value now, as opposed to having the function
take a pointer to a u64.
This gets rid of some assumptions that non-DiscIO code was making about
volume types. It's better to encapsulate as many of the volume type
differences as possible in DiscIO.
Made possible by PR #2353.
This is more reliable, as this guarantees subsystems will be
shut down in the same order they were initialised (if they were
initialised). It also allows us to stop keeping track of what needs to
be shut down manually and just return in case of errors.
This should prevent the emulator from getting totally stuck when
the boot process does fail.
This makes it hard to support different boot params for different boot
types. We should not be making the assumption that Dolphin will
always be booting directly from a file (and in particular, only
using a string).
It's incompatible with future changes that will allow Dolphin to boot
a NAND title properly from well, the NAND, as opposed to booting from
WADs. (And no, treating the title TMD as a "bootable" path doesn't
count. Especially when that approach won't work with NAND images
or IOS LLE.)
And it's confusing to expose this functionality from the UI. It's
pretty bad for UX to change the play button's behaviour depending on
whether the user has launched something before, configured a default
file to boot, added a directory to their game paths.
This commit moves the write function to where it should be (IOS),
especially when ES::ImportTicket() is the only place to use it.
Prevents misusing the ticket import function, and removes one unsafe
direct write to the NAND that does not go through IOS.
This also fixes the destination path: the session root is the one which
should be used for determining the ticket path, not the configured one.
The whole NANDContentLoader stuff is truly awful and will be removed
as soon as possible.
For now, this fixes a bug that was exposed by std::optional::operator*.
std::optional makes a few things a bit neater and less error prone.
However, we still cannot use C++17 (unfortunately), so this commit
adds an implementation of std::optional that we can use right now.
Based on https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/lib/gtl/optional.h
which seems to be fairly similar to C++17's <optional> and standards
compliant. It's one of the few implementations that handle propagating
type traits like copy constructibility, just like libc++/libstdc++.
`MainWindow` initializes a number of input interfaces but never shuts
them down. This was causing a crash-after-exit on macOS where the
ControllerInterface backend stores a `std::thread` object in a static
variable and only stops it when ControllerInterface::Shutdown is called.
FormLayout is not intended for this sort of dialog:
> QFormLayout is a convenience layout class that lays out its children
> in a two-column form. The left column consists of labels and the right
> column consists of "field" widgets (line editors, spin boxes, etc.).
pSysMem is of the type const void* -- because of this, it makes the
original delete[] call undefined behavior, as deleting a void pointer is
undefined behavior.
Also punning types into existence, like what was done for the stereo
image header is undefined behavior as well. The proper way to do this is
to either manually add all individual bytes manually, or memcpy the
struct into memory.
As we want to deallocate the memory before returning, and because
pSysMem is a const void*, we keep a unique_ptr to the data and just pass
pSysMem a raw pointer to the data.

gcc complains that the printf %x formatting instruction expects an
'unsigned int' but we pass a 'size_t'. We add the 'z' length formatting
specifier used for 'size_t'
This adds the WARNPC directive from xkas/asar to complement the existing ORG
directive. A common useful idiom is "WARNPC 0xXXXX\nORG 0xXXXX," which only
seeks forward and raises an error if you've already written to that part
of the file.
Fixes https://bugs.dolphin-emu.org/issues/10265 (Star Wars: The Clone
Wars hangs on loading screen with DSP-HLE and JIT Recompiler).
The Clone Wars hangs upon initial boot if this interrupt happens too
quickly after submitting a command list. When played in DSP-LLE, the
interrupt lags by about 160,000 cycles, though any value greater than or
equal to 814 will work. In other games, the lag can be as small as 50,000
cycles (in Metroid Prime) and as large as 718,092 cycles (in Tales of
Symphonia!).
All credit to @hthh, who put in a heroic(!) amount of detective work and
discovered that The Clone Wars tracks a "AXCommandListCycles" variable
which matches the aforementioned 160,000 cycles. It's initialized to ~2500
cycles for a minimal, empty command list, so that should be a safe number
for pretty much anything a game does (*crosses fingers*).
These settings are already loaded and saved to the SYSCONF. The INI
load/saves are redundant and do not work anyway because they are
overwritten by SYSCONF.
This file is pretty small now that it doesn't handle Wii
partitions anymore, so let's move its contents to Volume.cpp.
This is also more consistent with how blob creation works.
This happened to work without any problems because the only way for a
file system to be invalid was to not have the right GC/Wii magic word
in the unencrypted area, and a volume could not be created without
having the right GC/Wii magic word there. Now that file systems read
the magic word from a partition instead, a fix is needed.
I replaced m_OffsetShift with m_Wii in bb93336 to support
the decrypt parameter for read functions. Doing that is no
longer necessary, so m_offset_shift is now used like before.
By removing mutable state in VolumeWiiCrypted, this change makes
partition-related code simpler. It also gets rid of other ugly things,
like ISOProperties's "over 9000" loop that creates a list of
partitions by trying possible combinations, and DiscScrubber's
volume swapping that recreates the entire volume when it needs to
change partition.
- Makes DSP-LLE code checksums the same as those from DSP-HLE. I'm
assuming DSP-HLE was doing it correctly, since there are numerous
references to these pre-endian-swapped checksums (including in
DSPHost.cpp itself).
- Fixes disassembly when dumping code from DSP-LLE, which was using the
wrong endianness and giving totally bogus output.
- Reveals error messages of the format, "Bah! ReadAnnotatedAssembly
couldn't find the file ../../docs/DSP/DSP_UC_AX_07F88145.txt," which
seems to be intended behavior that was previously hidden.
This change centralizes all of the path handling and file writing logic
in DumpDSPCode. DSP-HLE also gains the feature of DSP-LLE to
automatically disassemble dumped code and write it to an accompanying
text file.
With the relocation of DumpDSPCode to DSPCodeUtils, the only remaining
function in DSPLLETools is DumpCWCode. This function 1) is not used
anywhere (not even in DSPTool), 2) doesn't seem to really do anything,
and 3) has a single comment saying "TODO make this useful :p"
This is something that should be the responsibility of the frontend
booting the game. Making this part of the host 'interface' inherently
requires frontends to leak internal details (much like the other
UI-related functions in the interface).
This also decouples more behavior from the debugger and the
initialization process in the wx frontend. This also eliminates several
usages of the parent menubar in the debugger code window.
VolumeDirectory doesn't support necessities like TMDs,
so thanks to 5.0-2172 (18968ab), EmulatedBS2_Wii crashes
when the inserted disc is a VolumeDirectory.
This commit fixes that.
This commit makes our DOL booting code very similar to our
ELF booting code. One exception is that the DOL booting
code still always calls SetupBAT. (Note that EmulatedBS2_GC
calls SetupBAT even if no disc is inserted.) I'm not sure
if there's a point to the difference, but I thought I'd
better avoid changing it so that I don't break anything.
For thread safety reasons, the currently inserted volume must
only be accessed by the DVD thread (or by the CPU thread if it
calls DVDThread::WaitUntilIdle() first). After this commit,
only DVDThread.cpp can access the volume, which prevents code in
other files from accessing the volume in a non-threadsafe way.
Direct access to the WAD bytes is required to read contents with proper
padding data (since they can sometimes end up being outside of the
data app section). Allowing the whole buffer to be accessed directly
would be error prone, so this commit adds GetContent() to WiiWAD
for getting raw content data by index.
These cannot be booted, so it is bad UX to show them in the UI as if
they were regular titles, and yet have different behaviour for them.
And technically, there is no reason to allow them to be used to boot
in the first place.
Another reason they should not be shown is that Dolphin fails
spectacularly with WADs that have a valid boot content index, but are
not PPC titles (e.g. IOS WADs). The only reliable way to avoid this
is to check for the title type and only show channels, just like
the Wii System Menu.
Mistakenly used the wrong TMD to clean up the import.
The original TMD is the one that is supposed to be used when
cancelling an import, but I forgot it's in the /import directory after
starting an import.
This exposes all ES title management ioctlvs to avoid duplicating IOS
code everywhere and to make it easier to reuse (since this way it's
not unnecessarily tied to the PPC IPC mechanism anymore) and unit test.
Some functions were also renamed for consistency with the other names,
*and* with official names.
It's better to just let the calling code provide a volume
object instead of needing one SetVolume for each way of
creating a volume. This simplifies InsertDiscCallback and
is needed for the following commits.
Just like DeleteTitle, Using CNANDContentManager is overkill,
inefficient and useless. And it results in a few failures in
situations where a delete should just always work.
But here it gets bonus points, because it manages to actually use
the TMD for deleting contents, when IOS does none of that and just
deletes files ending with .app in the title content directory. :)
This enables constructing an IOS instance that is not tied to emulation
and that can be simply used for internal purposes (ES, FS).
NAND root initialisation was moved to IOS since we cannot rely on HW
doing that for us anymore, and technically the NAND is entirely managed
by IOS anyway.
Default column width was being used for math related to automatic column sizing, in the case of COLUMN_SIZE the default width was -1 which resulted in an issue where an errant scrollbar would appear.
The MemoryWindow.cpp strings should be the same as the
MemoryCheckDlg.cpp strings so that translators don't
have to translate very similar strings twice.
Also adding i18n comments. These strings are *very* easy
to misinterpret in my opinion.
This is unsafe, because the NAND should not be accessed and messed with
while it is being used. In fact, this kind of inappropriate behaviour
will not be possible when we get NAND image support.
And even if there were no safety issue, there is still no reason
a *getter* function should *do* something that has lasting effects
on user data. GetWiiFSPath() should *just* return a path!
This adds code to update the PPC's UID and GID, which fixes a
regression with the system menu. Ideally, we would simply rely on IOS's
ES_Launch here and not duplicate the logic here, but we cannot do that
properly until the direct WAD launch hack is dropped, *and* until the
IOS changes that would enable internal calls are ready.
Since this fixes a semi-important regression with managing saves from
the SM, and the duplication is not too terrible, I believe it is a good
idea to get this fixed right now to avoid affecting users too much.
I do plan to fix this properly in the future.
* CNANDContentManager does things that are absolutely useless. In
particular, it parses the ticket, the TMD, reads contents, etc.
when we only need to remove the title directory.
* This means it will fail if the ticket cannot be found, when that
should not be the case.
* This also obviously caused DeleteTitle to be incredibly inefficient.
* We are already removing the title directory later in the function,
as CNANDContentManager does not even delete titles correctly.
DeleteTitle != DeleteTitleContents.
Since these button names are printed on all real controllers,
we should show them in the same way as they are printed on
the controllers, regardless of the user's language. It seems
like this was intended all along (except for "Start"), but the
_ markers in TASInputDlg.cpp (accidentally?) led to the button
names in the controller configs also becoming translatable.
I'm making exceptions for "L" and "R" because translators
may want to mark them in some way (for instance "L-Digital")
to clarify the difference from "L-Analog" and "R-Analog".
I'm also making an exception for START/PAUSE because it's
referred to as スタート in Japanese games.
I'm changing "Home" and "Start" to uppercase for consistency
with how Nintendo refers to those buttons, and because someone
who isn't familiar with the Latin script might not know the
connection between the lowercase and uppercase letters (most
users likely do know the connection, but we shouldn't assume it),
and because leaving "Start" as "Start" makes it "collide" with
unrelated strings, such as the string for the button that starts
a netplay session.
To rename "Start" and "Home" without breaking INI
compatibility, I added a ui_name variable like in f5c82ad.
* It should take a ticket view, not a title ID.
* It's missing a lot of checks.
* It's not deleting tickets properly.
* It's not deleting only the ticket it needs to delete.
* It should not return -1017 when the ticket doesn't exist.
* It's not returning the proper error code when a read/write fails.
* It's not cleaning up the ticket directory if there is nothing left.
This commit fixes its implementation.
* Supporting other ticket types makes the logic slightly more complex.
* There have been no such non-RSA2048 tickets seen during the Wii's
lifetime.
* The Wii's IOS doesn't even have support for them.
Stops CMake from saying "BlueZ NOT found, disabling bluetooth support"
on other OSes. Windows, macOS, and Android support Bluetooth using other
libraries. I'm not sure if non-Linux, non-Android Unices (like FreeBSD)
need another message?
The accuracy doesn't match ppc, and worse, it doesn't set the error flags if the input is zero.
Lets stop to ship broken instructions, so right now, the interpreter is the closest one.

This changes some parts of IOS (actually just ES) to reuse more crypto
code from IOSC or Common::AES.
TicketReader still returns the title key directly as opposed to having
ES use IOSC directly to avoid duplicating the title key IV stuff.
Side effects:
* A nasty unbounded array access bug is now fixed.
* ES_Decrypt/ES_Encrypt now returns sane results for keys other than
the SD key.
* Titles with a Korean ticket can now be decrypted properly.
And in the future, we can look into implementing ioctlv 0x3c and 0x3d
now that we have the proper "infra" for IOSC calls.
This prevents the IOS crypto code and keys from being spread over
the codebase. Things only have to be implemented once, and can be
used everywhere from the IOS code.
Additionally, since ES exposes some IOSC calls directly (DeleteObject
and Encrypt/Decrypt), we need this for proper emulation.
Currently, this only supports AES key objects.
Netplay uses a blank NAND, which means that homebrew launchers like
Gecko will force users to install IOSes.
Expecting netplay users to have a proper NAND setup is unrealistic,
and we don't actually give them a good way of syncing NANDs, so
let's extend the hack to netplay/TAS until we have a better way
of dealing with the issue.
This changes the main IOS code (roughly the equivalent of the kernel)
to a class instead of being a set of free functions + tons of static
variables.
The reason for this change is that keeping tons of static variables
like that prevents us from making an IOS instance and reusing IOS
code easily.
Converting the IOS code to a class also allows us to mostly decouple
IOS from the PPC emulation.
The more interesting changes are in Core/IOS/IOS. Everything else is
mostly just boring stuff required by this change...
* Because the devices themselves call back to the main IOS code
for various things (getting the current version, replying to a
request, and other syscall-like functions), just like processes in
IOS call kernel syscalls, we have to pass a reference to the kernel
to anything that uses IOS syscalls.
* Change DoState to save device names instead of device IDs to simplify
AddDevice() and get rid of an ugly static count.
* Change ES_Launch's ack to be sent at IOS boot, now that we can do
this properly.
It only marks a string for translation. It doesn't actually do anything
at runtime, so the string will always be displayed in English. Even if
we would've had a way to make the translation work, we shouldn't
translate this, because OSD doesn't support non-ASCII characters.
Some strings were marked with _trans in some places but not
others. This commit adds extra _trans markers so that the
usage of _trans is consistent.
This shouldn't have any effect on which strings actually get
translated. (Note that _trans doesn't do anything at runtime.)
I also added a few new i18n comments.
std::string's operator+ will handle this. Also move std::string to where
they're actually needed. There's no need to construct an unnecessary
string if the first failure case occurs.
This removes the need for multiple texture files to store the mipmap
chain for a texture. As many mipmaps will be loaded as are present in
the DDS file, and any remaining mipmaps will fall back to the old
behavior.
This changes the IOS code to handle ES contexts inside of ES, instead
of leaking out implementation details into the IPC request dispatcher.
The intent is to clarify what's shared between every single ES context,
and what is specific to an ES context. (Not much.) This should reduce
the number of static members in the ES class.
The other changes are there just because we now keep track of the
IPC FD inside of ES.
Future plans:
* After the WAD direct launch hack is dropped, the title context
will be made a class member.
* Have proper function prototypes, instead of having every single one
of them take ioctlv requests. This will allow reusing IOS code in
other parts of the Dolphin codebase without having to construct
ioctlv requests.
GTK2 is a dependency on Linux whenever USE_X11 is true, but we were
not linking or adding the include directory for GTK for DolphinWX.
Fixes a regression introduced by 6197d9622.
Simple quality-of-life addition that allows "uninstalling" WADs
(removing the corresponding installed title) from the NAND.
The option is only enabled when the WAD can be uninstalled
The motivation for this is actually to encourage proper usage of the
WAD launch feature (installing it to the NAND first), so we can
drop the "direct WAD title launch" hack.
Looking more carefully at the IOS ticket view generation code reveals
that the first field in the TicketView struct is copied over from
the ticket version, extended to 4 bytes.
This implements ES_SetUid, which is used by the system menu to change
its own permissions. This is required for implementing permission
checks and proper NAND metadata support in the future.
This fixes an error condition on macOS when HIDAPI calls
IOHIDManagerCreate and IOHIDManagerClose on different threads. The
error behavior is non-deterministic, but can cause EXC_BAD_ACCES and
kill the program.
This will be required for permission checks in the future.
Note that this is only for the PPC as we do not have actual processes.
Keeping track of other modules' UIDs/GIDs is virtually useless anyway.
UID/GID changes are implemented in the following functions:
* ES_Launch
* ES_DIVerify
ES_SetUid is not implemented yet because it'd need further changes.
Fixes an error with the CoreAudio backend, which apparently doesn't
allow you to set the volume before starting the stream:
```
59:31:087 AudioCommon/CoreAudioSoundStream.cpp:97 E[Audio]: error setting volume
```
This shouldn't cause any problems with other backends, since the mixer
starts with silence anyways.
The average user doesn't care, and for users who mix NTSC and PAL games
it avoids the "Memory Card is formatted for another market" message. For
non-average users, it's probably fine to have save data as separate
files anyways.
Might need some interface/string changes to explain what GCI Folder is
and why it's the default?
This is because we re-use BlendingState for our internal drawing (e.g.
RasterFont) and for these shaders, we can't assume the presence of a
second color output.
We can do this now that the x86-64 JIT supports PIE.
JITIL is deliberately excluded from the GUI because it
doesn't support PIE yet. (JITIL will be used if it's
set in the INI, though.)
This removes the need for token pasting, which isn't supported in GLSL
ES. Shouldn't cause any issues unless people are using reserved keywords
as option names.
Fixes file ordering in games that use ASCII characters between lowercase
'z' and uppercase 'A' (underscores).
MySims Kingdom has the files "terrainLightMapTinted.shader",

"terrainLightMapTinted.shader" and "terrainLightMapTintedGrid.shader",
which is invalid.

The audio backend option automatically gets disabled when
emulation is running, so it's pointless to tell people what
would (not) happen if they changed the audio backend while
emulation is running.
Currently, we use the alpha channel from the EFB even if the current
format does not include an alpha channel. Now, the alpha channel is set
to 1 if the format does not have an alpha channel, as well as truncating
to 5/6 bits per channel. This matches the EFB-to-texture behavior.
When playing a game on OS X, although the screen does not go to
sleep, the screensaver is still enabled, and therefore, during
gameplay, the screensaver may start running, which is not in
accordance to the behaviour on other other environments (Windows
and X11). It can be argued that the screensaver interrupting
gameplay is a nuissance to many players.
The changes in this commit are intended to allow Dolphin to disable
the screensaver during gameplay, just as intended on other platforms.
The changes have been tested on OS X 10.11 (El Capitan).
Also removes the unused Event_Adapter event stub which did nothing. It
wasn't even hooked up to wx's event system.
Allows removing several includes from the header file and moving them to
the cpp file. Prevents includes being dumped into other source files
that include the header.
This uncovered an indirect include in Main for MsgHandler utilities.
I replaced "1x IR" with "native internal resolution" because
the IR setting never says "1x" or "IR", and I also did some
minor rewording and normalized the sentence-ending spaces.
Rather than destroy and reinitialize the dialog whenever it's closed,
and opened this dialog can just be hidden from view when it's not
needed, and shown again when it is needed.
Also, a dialog should really not be managing any live instances of
itself, including the one directly in the main frame.
This gets rid of another usage of the main frame global.
Instead of allowing unknown ioctlvs and faking success for both unknown
and unimplemented ioctlvs, which can possibly result in nasty, hard to
debug bugs (if the emulated software behaves unexpectedly), we should
reject unknown ioctlvs and log known, but unimplemented ioctlvs.
Some widescreen hacks (see below) properly force anamorphic output, but
don't make the last projection in a frame 16:9, so Dolphin doesn't
display it correctly.
This changes the heuristic code to assume a frame is anamorphic based on
the total number of vertex flushes in 4:3 and 16:9 projections that
frame. It also adds a bit of "aspect ratio inertia" by making it harder
to switch aspect ratios, which takes care of aspect ratio flickering
that some games / widescreen hacks would be susceptible with the new
logic.
I've tested this on SSX Tricky's native anamorphic support, Tom Clancy's
Splinter Cell (it stayed in 4:3 the whole time), and on the following
widescreen hacks for which the heuristic doesn't currently work:

Fixes bug #10183 [0] introduced by 3bd184a / PR #4467 [1].
TextureCacheBase was no longer calling `entry->Load` for custom textures
since the compute shader decoding logic was added. This adds it back in.
It also slightly restructures the decoding if-group to match the one
below, which I think makes the logic more obvious.
(recommend viewing with `git diff -b` to ignore the indentation changes)

This is only ever queried and not set outside of the Core.cpp, so this
should just be hidden internally and just have a function exposed that
allows querying it.
wxQueueEvent/wxPostEvent are useful when the event is being dispatched
to another separate window, but aren't really necessary when the event
will be handled by the same window it's dispatched from.
GetEventHandler() is unnecessary here for the same reason. It's an event
intended to be handled by the dialog itself.
As all UI controls are essentially constructed with new expressions, the
type is already visible on the right-hand side, so repeating the type
twice isn't necessary.
This is an implementation detail that does not have to be exposed.
It was used in WII_IPC whenever the IPC gets reset, but that does not
make much sense to me: the only time when IOS loses state and the IPC
registers are set up again is when it's reloaded. And reloading IOS
already calls Reset() indirectly.
Also, an IPC reset from the PPC definitely should not close all opened
devices!
This also gets rid of a special case for clear_devices, which is now
completely unneeded.
This clashes with X11's preprocessor define named Success (because using
non-prefixed lowercase identifiers in C was apparently a fantastic idea
at some point), causing compilation errors.
Amends the TAS callbacks to internally store functions using
std::function instead of raw function pointers. This allows binding
extra contextual state via lambda functions, as well as keeping the
dialogs internal to the main frame (on top of being a more flexible
interface).
The loop was allocating one-too-many levels, as well as incorrect sizes
for each level. Probably not an issue as mipmapped render targets aren't
used, but the logic should be correct anyway.
This was a regression from the remove-everything-static-from-renderer
PR. As the comment indicates, it would be nice to move all of this logic
out of the Renderer constructor, but this is a much larger change.
This is currently unused and shouldn't actually be a part of the frame's
public interface. The event system should be used instead to dispatch
messages to the game list control if necessary.
This keeps all of the return codes in the same place and exposed
publicly (as they are not internal to ES).
I have also added proper IOSC error codes and renamed some codes
for more consistency. (Unix ones have an E prefix, others do not.)
A set of small changes to handle title imports more accurately.
* Clean up the import directory after an import, exactly like IOS.
This should prevent the title directory from having useless leftover
contents, which could confuse the emulated software.
* More robust failsafe in case an import does not complete normally.
IOS checks for stale imports and handles them appropriately on boot.
We now do the same.
* Create all directories as IOS does. This includes the data directory.
This may fix LIBUSB_ERROR_NOT_FOUND whenever devices end up being in
an unconfigured state. We don't need anything more than the first
config descriptor anyway.
This was a regression introduced by 4d8d045. stored_stack_pointer within
PPCSTATE was being accessed before the PPCSTATE (RBP) register was
initialized.

As the name is immediately stored into a class member, a move here is a
better choice.
This also moves the constructor implementations into the cpp file to
avoid an otherwise unnecessary inclusion in the header. This is also
likely a better choice as Section contains several non-trivial members,
so this would avoid potentially inlining a bunch of setup and teardown
code related to them as a side-benefit.
New Super Mario Bros on PAL still renders at 60 fps, but skips every 5th XFB copy.
So our detection of "per frame" fails, and we require twice the amound of texture objects.
But our pool frees unused textures after 3 frames, so half of them needs to be reallocated
every few frames.
This commit removes the lock for render targets. It was introduced to not update a texture
while it is still in use. But render targets aren't updated while rendering, so this
lock isn't needed. Non-rendertarget textures however aren't as dynamic, so the lock should
have no performance update.

Instead of each component allocating their own memory, we instead allocate
the memory once and divvy that up among the components as required. This
ensures that relative memory offsets remain within architecture limits.
Constants are copied into this pool so that they live at a memory
location that is close to the code that references it. The pool allocates
memory from a provided X64CodeBlock to use.
The purpose of the pool is to overcome the 32-bit offset limitation that
RIP-relative addressing has.`
Proper semantics.
IOS only cares about the TMD and nothing else, so we should use
FindInstalledTMD, instead of reading/parsing/decrypting a bunch of
useless stuff, which is slow *and* causes issues because of the cache.
If the delimiters of a memory aren't exactly the same as an address, but their size includes the memory breakpoint delimiter, the break will not go through. This makes it so that you can specify a search for a memory breakpoint with a data size and will check if the data fits with that size on all memory breakpoints so the breaks go through.
Dolphin assumes that content 0 is opening.bnr, without checking
whether content 0 exists or if it is even supposed to be there (it's
only there for channels). This results in sometimes reading garbage.
This adds a check to only try to read names from content 0's header
if the title is a channel (channel, system channel or game channel).
Trying to return to the Wii Menu from a game is the easiest
way to trigger this error. Just saying 0000000100000002
when that happens doesn't mean much to most users.
The Tools > Load System Menu option displays the version of the
installed Wii Menu. This commit changes the way we display that
version, like so: "Load System Menu 514P" -> "Load System Menu 4.3E"
The numbers are from http://wiibrew.org/wiki/System_Menu
The FrameBufferManager::CreateTexture (from the OpenGL backend) method introduced by commit 69cedf41 incorrectly compares the texture variable (which contains a name provided by glGenTextures) against GL_TEXTURE_2D_MULTISAMPLE_ARRAY and GL_TEXTURE_2D_MULTISAMPLE.
It should instead use the texture_type variable for this (as done in the first branch of the if).
5.0-2712 made ES's code for setting the game ID use the
title ID converted to hex (except for disc titles) instead
of using a 6-char game ID like before. Then, 5.0-2830 made
us use that code even when loading game INIs. This breaks the
expectations of both users and the game INIs we ship with.
This commit makes Dolphin use 6-char game IDs for all
titles (unless the 6-char ID would contain unprintable
characters, which is the case with e.g. the Wii Menu).
I'm also putting unprintability checks in VolumeWad
for consistency.
Places all of the SI code under the SerialInterface namespace instead of

This commit should have zero performance effect if SSBOs are supported.
If they aren't (e.g. on all Macs), this commit alters FramebufferManager
to attach a new stencil buffer and VertexManager to draw to it when
bounding box is active. `BBoxRead` gets the pixel data from the buffer
and dumbly loops through it to find the bounding box.
This patch can run Paper Mario: The Thousand-Year Door at almost full
speed (50–60 FPS) without Dual-Core enabled for all common bounding
box-using actions I tested (going through pipes, Plane Mode, Paper
Mode, Prof. Frankly's gate, combat, walking around the overworld, etc.)
on my computer (macOS 10.12.3, 2.8 GHz Intel Core i7, 16 GB 1600 MHz
DDR3, and Intel Iris 1536 MB).
A few more demanding scenes (e.g. the self-building bridge on the way
to Petalburg) slow to ~15% of their speed without this patch (though
they don't run quite at full speed even on master). The slowdown is
caused almost solely by `glReadPixels` in `OGL::BoundingBox::Get`.
Other implementation ideas:
- Use a stencil buffer that's separate from the depth buffer. This would
require ARB_texture_stencil8 / OpenGL 4.4, which isn't available on
macOS.
- Use `glGetTexImage` instead of `glReadPixels`. This is ~5 FPS slower
on my computer, presumably because it has to transfer the entire
combined depth-stencil buffer instead of only the stencil data.
Getting only stencil data from `glGetTexImage` requires
ARB_texture_stencil8 / OpenGL 4.4, which (again) is not available on
macOS.
- Don't use a PBO, and use `glReadPixels` synchronously. This has no
visible performance effect on my computer, and is theoretically
slower.
GCMemcard.h has quite a bit of different classes implemented within it
that could likely be split up into other files to make it a little
easier to read. However, they should be moved into their own folder
first so that they don't clutter up the base HW directory.
Defaulting to SSL verification off, *and* forcing it to be off even
when the emulated software asks us to enable it is very bad behaviour,
inaccurate and insecure.
Because the old option defaulted to off, we have to change the INI
option name to force the new default to be used. Unfortunate,
but without this we cannot ensure our users' security.
LoadPatches was apparently never being called when booting
Wii discs. Maybe this will fix the recent regression with
cheat codes not getting loaded? I don't know how this
managed to work to begin with, though...
(The call was also moved for WADs, just for consistency.)
ES.cpp was becoming pretty huge. This commit splits the ES code into
several files:
* Main ES (launch, UID, current title directory and title ID, etc.)
* Device identity and encryption (ID and cert, keys, encrypt/decrypt)
* Title management (imports, exports, deletions)
* Title contents (open/close/read/seek)
* Title information (titles, stored contents, TMDs)
* Views (for tickets and TMDs)
This prevents truncation when assigning to this member in the
constructor. This isn't size-critical code, so opting for the more
straightforward assignment is fine here.
Advantages:
* Simpler code in general
* No extra volume objects created
* Now actually notices if the disc or partition gets
changed while the core is running
* No longer picks up on disc access done by the GUI
(it used to do so as long as the core was running)
* Gets rid of a Core dependency in DiscIO
There are two performance disadvantages:
* FileMonitor is now a bit slower when used with VolumeDirectory
because FileMonitor now always uses the FileSystemGCWii code
for finding filenames instead of VolumeDirectory finding the
filename on its own and directly hooking into FileMonitor.
But this isn't such a big deal, because it's happening on the
DVD thread, and my currently unmerged file system PR will make
FileSystemGCWii's file finding code about as fast as
VolumeDirectory's.
* FileMonitor's creation of the file system object is now
done on the CPU thread instead of the DVD thread, and
it will be done even if FileMonitor logging is disabled.
This will be fixed in the next commit.
PR #3582 removed VolumeIsValid, then PR #3582 added a call
to VolumeIsValid, then both PRs were merged without either
of them being rebased on top of the other.
There's no point in creating a volume without a blob,
since essentially all the functionality of a volume
requires a blob to be used.
Also, VolumeCreator doesn't support creating volumes
without blobs (it can't even figure out the volume type
unless it gets a blob), so it's currently impossible
for a volume to be created without a blob.
Given none of these are used outside of the DSPEmitter class (nor does
it really make sense to allow them to be used outside of the class),
these should all be made private.
Using DiscIO's NAND content loader is the wrong way to get the ticket
for a title, because it checks whether the TMD is present and the
validity check fails if it isn't. This is not the correct behaviour:
we should just read the ticket from /ticket without caring about TMDs.
* IOS doesn't rely on the number of contents indicated in the TMD.
Instead, it checks whether the contents *do* exist on the NAND.
* Implement ES_GetTMDStoredContents (and the count ioctlv).
* Drop a hack in ES_GetStoredContents, which is unnecessary now that
we do it properly.
This is slightly safer than writing contents to /title directly.
We still cannot rename everything in one go atomically, but this allows
implementing AddTitleCancel very easily.
Also, this ensures that when a title import fails, no incomplete files
will be left in the title directory, which can mess up the system menu.
Regression introduced in e99cd57 / 4935: VideoBackends: Set the maximum
range when the depth range is oversized[1]. The NV_depth_buffer_float
extension is not part of OpenGL 3.0, and requiring it causes a hard
crash when it's not supported (e.g. macOS).
[1]: https://github.com/dolphin-emu/dolphin/pull/4935
Most of the Volume code was written before this
convenience function was added. Let's use it more.
Also deleting m_pReader nullptr checks that are
unnecessary because of Read (which ReadSwapped calls)
already having a nullptr check.
This stops the virtual method call from within the Renderer constructor.
The initialization here for GL had to be moved to VideoBackend, as the
Renderer constructor will not have been executed before the value is
required.
This adds a check to the SSL code to make sure we are using the correct
client certificate and key (and root CA).
Now, instead of silently failing, the user will be notified whenever a
file is missing or when it is invalid, i.e. when the hash does not
match; this is likely to happen for existing users as the program
linked in the network guide extracted the wrong certs :(
This partially restores a hack which causes ES to fake ticket views for
IOS titles.
This is necessary because we still allow users to boot games from the
game list, so, with no way of making sure the required IOSes are
installed beforehand, games may OSPanic() when they try to reload to
some IOS version and just find out that the IOS is not installed
(something which *never* happens on the real console, of course).
A warning is printed in the logs to make sure technical users know the
IOS titles are being faked. To try and keep things accurate in all
other cases, this hack is only active when it is needed (when the
current title is a disc title which was launched from the game list).
Depending upon the desktop colour scheme, the light/dark
GameList backgrounds can cause the always white text
to become unreadble.
Use the common luminance approximation algorithm to
determine whether black text should be used instead.
This adds a hash check for imported contents. IOS does it for security;
we do it for a somewhat different reason, to catch content decryption
bugs before incorrectly decrypted contents get written to the NAND,
which can cause titles to be corrupted.
Either way, we should have been doing this check in all cases.
const, when used on value type parameters in the declaration,
is superfluous. This doesn't really convey any information to take note
of when using the function. This only matters in the definition when you
want to prevent accidental modification.
e.g.
// Header
void CalculateSomething(int lhs, int rhs);
// Definition
void CalculateSomething(const int lhs, const int rhs)
{
// lhs and rhs can't accidentally be modified
}
When the TMD doesn't exist on the NAND, IOS returns -106.
This commit also changes IsValid() to not check for the TMD validity,
since this is not always something we want. (IOS can have different
error codes when the TMD is missing, or even worse, simply assume
that the TMD is valid.)
IOS determines installed titles by looking at /title, not uid.sys,
which is more like a history of installed titles. And it does not care
at all about the installed TMD (or even if it is present at all).
This moves all the byte swapping utilities into a header named Swap.h.
A dedicated header is much more preferable here due to the size of the
code itself. In general usage throughout the codebase, CommonFuncs.h was
generally only included for these functions anyway. These being in their
own header avoids dumping the lesser used utilities into scope. As well
as providing a localized area for more utilities related to byte
swapping in the future (should they be needed). This also makes it nicer
to identify which files depend on the byte swapping utilities in
particular.
Since this is a completely new header, moving the code uncovered a few
indirect includes, as well as making some other inclusions unnecessary.
Not only this is pretty pointless because there is a load and save button on the appropriate panels, but for the breakpoints one, it caused an error while mapping the memory since adding memory breakpoint requires to update the DBAT and this is done too early (right after boot). This also only worked if you had the right panel on making it even more useless because it would fail to laod if you didn't have the right panel on. It's better to just let the user click load and save.
This removes wrappers for ES_DIVerify and ES::LoadWAD. They are not
really useful as we can simply call the ES function directly, and
it is actually somewhat confusing because both functions are static
and are not tied to a particular ES instance.
This allows Dolphin to stay up-to-date about what title is currently
running, which fixes savestates, screenshots, etc. after an ES_Launch.
Same limitation as with MIOS: currently, GameINIs are not reloaded,
because it's a pain with the current config system. It'll happen
when the new config system is done, and this commit makes it much
easier to do!
Some members are shared between ES instances, and they are just global
variables in IOS.
This is more efficient than getting the installed titles or setting the
current active title tons of times for no reason.
This changes ES to keep track of the active title properly,
just like IOS:
* It is NOT changed on resource manager open/close.
* It is reset on IOS reload.
* It is changed by ES_DIVerify and ES_Launch.
IOS stores the active title in a structure like this:
struct ESTitleContext
{
Ticket* ticket;
TMD* tmd;
u32 active;
};
With this commit, we also do keep the Ticket and TMD around. This
makes some of the DI ioctlvs (which return data about the current
active title) trivial to implement in the future.
This fixes the System Menu not being able to see update partitions
and also allows us to change Dolphin's active game info in the future.
Currently, slowmem is used at any time that memory breakpoints are in use. This commit makes it so that whenever the DBAT gets updated, if the address is overllaping any memchecks, it forces the use of slowmem. This allows to keep fastmem for any other cases and noticably increases performance when using memory breakpoints.
This fixes ES_GetTMDView and ES_GetTMDViewSize to return -106
(FS_ENOENT) if the title does not exist (and more specifically when no
TMD exists in the NAND). This allows installed (or not installed) IOSes
to be detected properly.
It makes absolutely no sense to have asserts for what is obviously an
error condition. And they should definitely not cause Dolphin to crash
because it assumes that everything is valid, and Dolphin should not
report those to the user either, as it is very obviously a bug in the
emulated software and there is nothing the user (or we) can do.
This commit replaces all of the request asserts with proper checks
and adds missing checks for some ioctlvs. We still do not check sizes
yet; this will be done later.
Before #4581, an invocation of `SetBlendMode` could invoke
`glBlendEquationSeparate` and `glBlendFuncSeparate` even when it was
setting `glDisable(GL_BLEND)`. I couldn't figure out how to map the old
behavior over to the new BlendingState code, so I changed it to always
call the two blend functions.
Fixes https://bugs.dolphin-emu.org/issues/10120 : "Sonic Adventure 2
Battle: graphics crash when loading first Dark level".
Currently, slowmem is used at any time that memory breakpoints are in use. This commit makes it so that whenever the DBAT gets updated, if the address is overllaping any memchecks, it forces the use of slowmem. This allows to keep fastmem for any other cases and noticably increases performance when using memory breakpoints.
The vector was not constructed with the proper size, which results in a
buffer overflow as we were using memcpy.
This commit fixes that mistake and also uses a safer way of copying the
ticket view data (std::vector::insert instead of memcpy).
This commit fixes ES_Launch to work mostly the same as the real IOS
(except temporary, internal files such as /sys/launch.sys and title
handling; the latter will be handled in a future PR).
First of all, this adds two IOS functions, which correspond to two
IOS syscalls: 0x41 (boot_ppc) and 0x42 (boot_ios).
boot_ios() writes the new version to 0x3140, loads the new kernel,
which then proceeds to reinit IPC and load modules as part of its
boot process. Note that this doesn't include writing to any of the
other constants in the 0x3100 region.
In Dolphin, this is implemented by changing the active IOS
version variable, writing to 0x3140 and resetting all devices. This
has exactly the same effect as the real syscall.
The other syscall, boot_ppc(), writes code to the EXI boot buffer,
pokes all constants to memory before bootstrapping the PPC with a
binary from the NAND.
We skip the low level stuff and just load the DOL to memory (and set
the PPC's PC to 0x3400), which is essentially what IOS does.
The other change is mostly related to how ES_Launch is handled.
With a real IOS, if the launched title type is 00000001 (system) and
the title is not 1-2 (System Menu), ES calls boot_ios().
Otherwise, ES handles the launch as a PPC title. It reads the TMD
to determine the required IOS version. If it is the same, boot_ppc()
is called directly. If not, ES saves the title to launch to the NAND
before launching the new IOS. After the new IOS has finished booting,
it will notice the flag and then launch the requested title.
What this commit does is really just implement this logic into IOS HLE.
The result is a fix for a regression introduced by SetupMemory,
where reloading an IOS would have overwritten some OS constants.
This fixes booting games from the disc channel.
No idea why this wasn't implemented whereas ES_DeleteTicket and
ES_DeleteTitleContent were.
This probably fixes title deletion in old System Menus, and maybe
the new ones as well in some cases; I've seen 4.3 use this ioctlv.

Fix this by overriding wxApp::OnCmdLineParsed to disable the default

DolphinApp::OnInitCmdLine).
We already have a TMDReader, so let's actually use it.
And move ESFormats to IOS::ES, since it's definitely part of IOS.

driver is initialized), *not* when /dev/fs is opened.
Although this should have no effect, it fixes the case where files
could be left in /tmp and seen before opening /dev/fs.
Gets some constants out of the ControllerEmu namespace, and modifies
ControlGroup so that it uses the enum type itself to represent the
underlying type, rather than a u32 value.
As this is a base class with virtuals, there needs to be an out-of-line
function definition to prevent the vtable of the class being placed within
every translation unit it's used in (i.e. every JIT implementation).
Getting and setting configuration from the base config layer are common
and repetitive tasks. This commit adds some simpler to use functions to
make the new system easier to work with.
Config::Get and Config::Set are intended to make switching from
SConfig a bit less painful. They always operate on the main system.
Example usage:
// before
auto base_layer = Config::GetLayer(Config::LayerType::Base);
auto core = base_layer->GetOrCreateSection(Config::System::Main, "Core");
u8 language;
core->Get("Language", &language, 0);
SetData("IPL.LNG", language);
// now
auto base_layer = Config::GetLayer(Config::LayerType::Base);
auto core = base_layer->GetOrCreateSection(Config::System::Main, "Core");
SetData("IPL.LNG", core->Get<u8>("Language", 0));
// or simply
SetData("IPL.LNG", Config::Get<u8>("Core", "Language", 0));
It is kind of silly to connect all of the configured Wii remotes (from
the user config; NOT netplay assigned remotes), then connect/disconnect
additional Wii remotes *after* the core has booted.
(The bWii check has been removed, because it's actually unneeded;
m_wiimote_map is always usable regardless of bWii. And we can't get
info about the currently running game without booting the core with our
current config system…)
This should fix Netplay trying to connect all configured Wii remotes.
Fixes a logic bug I introduced as part of #4942. We were not
handling the "read past EOF" case correctly, which caused
requested_read_length to underflow in some cases.
Also fixes a comparison (though this is unlikely to change anything).
Instead, the JitInterface namespace functions should be used instead. This
gets rid of all usages of the JIT global from the wxWidgets UI code.
The null check isn't needed as the JIT core would already need to be
initialized in order to be within a paused state. The null check is just a
remnant from 2011 that existed before the check for a paused state was
added.
This changes the read request handler to work just like IOS:
* To make things clearer, we now return early from error conditions,
instead of having nested ifs.
* IOS does an additional check on the requested read length, and
substracts the current seek position from it, if the read would
cause IOS to read past the EOF (not sure what the purpose of this
check is, but IOS does it, so we should too).
* The most significant one: IOS does *not* return the requested read
length, or update the file seek position with it. Instead, it uses
the *actual* read length.
As a result of simply doing what IOS does, this fixes _Mushroom Men_.
The game creates a save file, reads 2560 bytes from it, then
immediately writes 16384 bytes to it. With IOS, the first read does not
change the seek position at all, so the save data is written at
offset 0, not 2560. With Dolphin, the read erroneously set the
seek position to 2560, which caused the data to be written at
the wrong location.
Behavior confirmed by comparing IPC replies with IOS LLE and by looking
at the FS module in IOS.
What we actually care about is whether it's a GCZ file,
not whether it's compressed. (This commit doesn't change
the behavior, since the beginning of CompressSelection
discards items that aren't BlobType::GCZ or BlobType::PLAIN.)
- There's no clear definition of what it means for a GC/Wii game
to be compressed. GC games in GCZ are obviously compressed,
but what about formats like WBFS and CISO that just discard data?
- Hardcoded colors might have bad contrast with the used theme.
- It feels Windows XP to me.
YYCJ is one of the last titles to be completely broken in Dolphin.
It would hang right after the Wii remote screen. Looking at the
game's debug messages reveals that it was failing to find some of
its files.
IOS LLE booted the game just fine, which confirmed that it was an issue
with IOS HLE.
By comparing the ioctlv requests and responses with IOS, it turns out
that one of the very first ES replies was different between IOS HLE and
IOS: there was a mismatch for the content fd returned by ES.
Changing the initial content FD to what IOS returns fixes the issue.

So where did 0x6000000 come from?
4bd5674 changed "Wiimote" to "Wii Remote" in the GUI
(intentionally) but also did the same change for two INI
keys (seemingly unintentional, breaks backwards compatibility,
and is inconsistent with the INI's filename). This commit
reverts the INI keys but not the GUI strings.
This commit uses the same approach as cbd539e used for GameCube
sticks (but I made sure to avoid the bug that 56531a0 fixed).
Given a std::map can't have duplicate keys, iterating over the map
explicitly isn't necessary, and find() can just be used instead.
Also, instead of manually calling push_back() for every entry to
be added, the range constructor of std::vector can be used instead to add
the whole range all at once.
We (the Microsoft C++ team) use the dolphin project as part of our "Real world code" tests.
I noticed a few issues in windows specific code when building dolphin with the MSVC compiler
in its conformance mode (/permissive-). For more information on /permissive- see our blog
https://blogs.msdn.microsoft.com/vcblog/2016/11/16/permissive-switch/.
These changes are to address 3 different types of issues:
1) Use of qualified names in member declarations
struct A {
void A::f() { } // error C4596: illegal qualified name in member declaration
// remove redundant 'A::' to fix
};
2) Binding a non-const reference to a temporary
struct S{};
// If arg is in 'in' parameter, then it should be made const.
void func(S& arg){}
int main() {
//error C2664: 'void func(S &)': cannot convert argument 1 from 'S' to 'S &'
//note: A non-const reference may only be bound to an lvalue
func( S() );
//Work around this by creating a local, and using it to call the function
S s;
func( s );
}
3) Add missing #include <intrin.h>
Because of the workaround you are using in the code you will need to include
this. This is because of changes in the libraries and not /permissive-
This adds memory values for IOS11, 20, 30, 50, 51, 52, 60 and 70.
Unfortunately, IOS40 (in its working version) is not present on NUS, so
constants for that one are still missing.
This is something I removed by mistake. It didn't break anything in
most titles, but the Mii Channel *requires* write requests to
/dev/usb/kbd to succeed before exiting, so this commit readds the stub.
The latest version has tons of security fixes (which is expected for a
library such as mbedtls).
Updating also allows getting rid of a few deprecation warnings.
Turns out it is completely unneeded and it actually works better
*without* it.
Just try launching the system menu from the HBC; in current master, it
will disconnect the remote and not connect it automatically again. With
this change, it will.
The recent IOS initialization changes caused the Bluetooth device to
no longer exist before "starting" IOS (as it should be…), which meant
that Core could not activate Wii remotes during the boot process
anymore.
But that is actually completely useless, because we can just have the
emulated Bluetooth code itself activate Wii remotes as appropriate,
at the right moment.
wxWidgets headers don't play well with some of the macros defined in
Windows headers and perform their own magic to fix things, as long as
they're included entirely either before or after any Windows headers.
This file can cause a conflict in other DolphinWX files because NetPlay
headers directly include ENet headers, which leak Windows header macros.
To fix this, explicitly tell wxWidgets here that it needs to re-clean
macros.
We can return early from invalid conditions, which allows getting rid
of quite a few levels of indentation.
And let's not duplicate the new_position > file_size check.
ControllerEmu::Control instances have a unique_ptr<ControlReference>
member, which is passed either an InputReference or OutputReference.
Without this virtual destructor, deleting a derived class through a
pointer to the base class is undefined behavior.
This prevents Dolphin from writing to /sys/uid.sys (on the host; root
partition) when installing a WAD before starting emulation, because
the session root is not initialized at that moment.
Incidentally, this also gets rid of a singleton.
instruction tables
Previously, all of the internals that handled how the instruction tables
are initialized were exposed externally. However, this can all be made
private to each CPU backend.
If each backend has an Init() function, then this is where the instruction
tables should be initialized, it shouldn't be the responsibility of
external code to ensure internal validity.
This allows for getting rid of all the table initialization shenanigans
within JitInterface and PPCTables.
ControllerEmu, the class, is essentially acting like a namespace for
ControlGroup. This makes it impossible to forward declare any of the
internals. It also globs a bunch of classes together which is kind of a
pain to manage.
This splits ControlGroup and the classes it contains into their own source
files and situates them all within a namespace, which gets them out of
global scope.
Since this allows forward declarations for the once-internal classes, it
now requires significantly less files to be rebuilt if anything is changed
in the ControllerEmu portion of code.
It does not split out the settings classes yet, however, as it
would be preferable to make a settings base class that all settings derive
from, but this would be a functional change -- this commit only intends to
move around existing code. Extracting the settings class will be done in
another commit.
Several of the things done while performing a scan are logically their own
behavior (e.g. loading a titles file, checking if an entry should be added, etc).
The three parameter AnalogStick constructor takes an internal name, a
display name, and a default radius argument. The delegated constructor is
the one that calls the ControlGroup constructor, setting the group type,
so passing the group type here is a logic bug.
The only reason this appeared to work despite this bug is because
GROUP_TYPE_STICK has a value of 1, and the default radius value used for
attachment sticks is 1.0.
This implements MIOS's PPC bootstrapping functionality, which enables
users to start a GameCube game from the Wii System Menu.
Because we aren't doing Starlet LLE (and don't have a boot1), we can
just jump to MIOS when the emulated software does an ES_LAUNCH or uses
ioctlv 0x25 to launch BC.
Note that the process is more complex on a real Wii and goes through
several more steps before getting to MIOS:
* The System Menu detects a GameCube disc and launches BC (1-100)
instead of the game. [Dolphin does this too.]
* BC, which is reportedly very similar to boot1, lowers the Hollywood
clock speed to the Flipper's and then launches boot2.
* boot2 sees the lowered clock speed and launches MIOS (1-101) instead
of the System Menu.
MIOS runs instead of IOS in GC mode and has an embedded GC IPL (which
is the code actually responsible for loading the disc game) and a PPC
bootstrap code. To get things working properly, we simply need to load
both to memory, then jump to the bootstrap code at 0x3400.
Obviously, because of the way this works, a real MIOS is required.
It held a raw pointer to a IOS::HLE::Device::BluetoothEmu that is not
guaranteed to exist (and of course, nothing checked that it wasn't
nullptr), but what is more, it's totally unnecessary because we have
IOS::HLE::GetDeviceByName().
Since we cannot always inform the host that Wii remotes are
disconnected from ES, that is now done in BluetoothEmu's destructor.
Unless IOS failed at ES_Launch, it doesn't appear to write anything
back to the request after a launch, because the request is never
actually replied to in the normal way.
So let's just drop the writes to make things less confusing.
This ioctlv is used to launch BC. Not sure if that's useful,
since only the system menu is known to launch BC and it does that
through a regular ES_LAUNCH; but let's implement it anyway.
(Implementation based on IOS59.)
Some minor changes to make things slightly less confusing:
* Reinit doesn't actually init anything. It just adds static devices to
the map, so let's give it an actually descriptive name. And let's not
expose it in the header when it should not be.
* Reset's parameter name was changed from "force" -- which totally does
not describe what it does -- to "clear_devices".
* Add a reload function which handles the reload process properly
(reset all devices, set up memory values, re-add devices) and
without publicly exposing implementation details.
Shouldn't make any difference in practice because
both IsRecordingInput and IsNetPlayRunning should
be false if a temporary NAND isn't being set up,
but doing it this way is cleaner regardless.
Splits DVD reads up into smaller chunks so that data is available
before the final interrupt is triggered. This better simulates the DMA
that happens on a real device, which some games will take advantage of -
by either playing back data as it is loading or by using data that is
going to be overwritten shortly by an outstanding read.
Better separation of concerns. Relegates `ControllerInterface` to
enumerating input controls, and the new `ControlReference` deals with
combining inputs and configuration expression parsing.
ControllerEmu is a massive class with a lot of nested public classes.
The only reason these are nested is because the outer class acts as a
namespace. There's no reason to keep these classes nested just for that.
Keeping these classes nested makes it impossible to forward declare them, which leads to quite a few includes in other headers, making compilation take
longer.
This moves the source files to their own directory so classes can be
separated as necessary to their own source files, and be namespaced under the
ControllerEmu namespace.
To use it, with a modern LLVM (3.9+), set your CMAKE_PREFIX_PATH
to point to the LLVM install folder or to a LLVM build folder.
We're linking ALL of LLVM libs since I don't really know which ones we need.
LTO will take care of sliming the binary size...
The second output vector should not be written to for
IOCTLV_NCD_READCONFIG. If it is, the system menu will never attempt
to open /dev/net/wd/command and request a Wi-Fi scan.
Symbols map may not only end with a \n, but they may also end with \r\n and only the \n would get removed. This is the case with the Super Mario Sunshine map file which resulted in a weird looking symbols list and thus made it harder to scroll through it. This removes the \r after the \n has been removed if it's present.
Using the AVCodecContext contained in AVStream for muxing is officially
discouraged[1] and AVStream::codec was deprecated in favor of
AVStream::codecpar in libavformat 57.33.100 / 57.5.0.
1: [FFmpeg-cvslog] lavf: replace AVStream.codec with AVStream.codecpar: https://ffmpeg.org/pipermail/ffmpeg-cvslog/2016-April/099152.html
Any functions left exposed are used elsewhere through the main_window
global. May as well prevent any more functions from being used in that
manner where possible.
Utilizes the event system (which is what should have been done here
initially), in order to prevent coupling between two different window frames.
This also makes booting games more versatile using the UI event system,
as the event can just act as a carrier for the filename, making directly
calling boot functions unnecessary. All that's needed is for the event to
propagate to the frame.
Since files from Data/Sys are collected and added to a built macOS .app
bundle using GLOB, any new files won't get picked up until the next time
CMake is run. Tell CMake it should re-run itself every time the directory
is touched.
This prevents panic alerts from showing up three times when starting
Wii emulation whenever libusb could not be initialized. The user has
already seen a warning at startup -- no need to warn them 3 more times.
The built-in `configure_file` command correctly handles the case where
none of the variables change and scmrev.h doesn't need to be rebuilt.
This saves a full re-link of Dolphin any time CMake is re-run.
This reimplements the USB HID v4 IOS device using the new common
USB code (to reuse more code and allow emulated HIDs to be added
more easily in the future).
The main difference is that HIDs now have to be whitelisted, like
every other USB device for OH0 and VEN.
libusb on Windows is limited to only a single context. Trying to open
more than one can cause device enumerations to fail randomly.
libusb is thread-safe and we don't use the manual polling support (with
`poll()`) so this should be safe.
The Host class will be used by the OH0, VEN and HID implementations
as the base class for the IOS HLE device. It handles scanning devices,
detecting device changes and everything that will be needed for OH0,
VEN and HID to be implemented, while mostly abstracting libusb away.
The Device class is for actual USB devices. This commit adds a
LibusbDevice which interacts with a real USB device and enables
USB passthrough.
The NullAudio backend is guaranteed to be compiled in, so no reason
to check it.
In addition to that, if it wasn't valid, it wouldn't work as a fallback
in InitSoundStream as there are uses to g_sound_stream later.
Keeps associated data together. It also eliminates the possibility of out
parameters not being initialized properly. For example, consider the
following example:
-- some FramebufferManager implementation --
void FBMgrImpl::GetTargetSize(u32* width, u32* height) override
{
// Do nothing
}
-- somewhere else where the function is used --
u32 width, height;
framebuffer_manager_instance->GetTargetSize(&width, &height);
if (texture_width != width) <-- Uninitialized variable usage
{
...
}
It makes it much more obvious to spot any initialization issues, because
it requires something to be returned, as opposed to allowing an
implementation to just not do anything.
Movie basically just wants to get the title ID of
the initally booted game, so let's set the title ID in
ConfigManager at boot like we do with the regular game ID.
Aside from being cleaner, this should make the approach to
title IDs compatible with booting non-disc software (WADs).
This is unnecessary now that IOS::HLE is responsible for writing the
values to memory; removing the writes also prevents the IOS minor
version from being mangled (by the write to 0x3142).
Instead of using install() commands, we use the MACOSX_PACKAGE_LOCATION
property, which will allow the files to be identified and updated individually
by the build system without having to remove the entire folder and copy it
each time.
deploy-mac.py is now idempotent and should be working properly, so we'll
call it all the time from now on.
On macOS, we want them copied in the bundle directly, otherwise we will
install them later in the system folder.
Obviously not working for Windows, but that's not any different from before!
Forward declaring functions from a completely different header inside a cpp
file can lead to linker errors. Forward declaring also doesn't really
provide any benefit within cpp files unless it's to bring an internally
linked function within the same file into scope.
Hopefully will fix the crash in vkDestroyInstance on the NV Shield TV,
and likely reduce boot times slightly for drivers that take a while
to create instances.
Makes it more self-documenting which stack is being loaded or stored to,
as C, D, and magic numbers are extremely vague. It also enforces a
strongly-typed API instead of accepting arbitrary integral values.
It also adds the two other missing stack register names -- loop address
and loop counter.
This fixes a crash when trying to open the advanced input config dialog on the wiimote extensions. The device_cbox wasn't initialised and it should have been with the wiimote one.
These quite clearly have a dependency on the emitter itself, so these
should be a part of the emitter itself.
The template function can be modified to just simply take functions as a
parameter.
This function is exceptionally large. Everything within a switch like this
also makes it quite error prone. Separating the functions out makes it
easier to change a certain request implementation as well as improving
code locality.
This fixes savestates when using Bluetooth passthrough by keeping track
of pending transfer commands and discarding them on state load, so that
the emulated software receives a reply to IOS requests as expected.
With this change, savestates in BT passthrough should work as long as
no Wiimote is connected when creating the savestate and when
restoring it. Yes, I know this is an important limitation -- but
that is probably the best we can do, and it's still better than
completely broken savestates.
This fixes a regression from 5.0-1556, but I don't know why
the regression occurred or why this fixes it. (Many games
failed to fully boot - I tried Metroid Prime and Twilight
Princess (both GC), and they never got to the title screen.)
TryReadInstruction doesn't validate the address it resolves, that
can result in Memory::GetPointer failing and returning nullptr
which then leads to a nullptr dereference and a crash.
Created PowerPC::HostIsInstructionRAMAddress which works the same
way as PowerPC::HostIsRAMAddress for the IBAT.
This is useful to know which IOS version is required by a title without
having to look at the TMD manually.
The IOS version row will only appear if there is a TMD, of course.
File paths passed to it would have been implicitly converted to std::strings
prior to this function being reached, so it gets rid of some string churn.
It also makes it safer since nullptr can't be passed in.
Drops prefixed underscores from parameters
The C++14 standard states in section 2.10 subsection 3.2:
"Each identifier that begins with an underscore is reserved to the
implementation for use as a name in the global namespace."
It's highly unlikely an implementation will ever use '_inst' as a global
identifier, however it's better to just amend the names and alleviate
the concern altogether.
Some structures will be reused and shared between several IOS USB
device implementations. This prepares for the upcoming USB PR.
I've also removed GetPointer calls in the trivial case (BT passthrough)
Hides the opcode tables that the interpreter and JIT interface with to
execute instructions.
This does not, however, hide the read-only tables that the assembler and
disassembler use.
If we don't check for Core::IsRunning(), event types such as
iosNotifyResetButton may actually be nullptr, or some random invalid
pointer (after an emulation start then shutdown) and be used when the
user triggers a reset, which causes random crashes.
Makes it more obvious which data is going into the savestate.
It also allows PowerPCState and InstructionCache to potentially
contain members that don't necessarily need to be saved to the save state.
It also gets rid of any potential padding data being put into the save
state.
IPC_HLE is actually IOS HLE. The actual IPC emulation is not in
IPC_HLE, but in HW/WII_IPC.cpp. So calling IPC_HLE IOS is more
accurate. (If IOS LLE gets ever implemented, it'll likely be at
a lower level -- Starlet LLE.)
This also totally gets rid of the IPC_HLE prefix in file names, and
moves some source files to their own subdirectories to make the file
hierarchy cleaner.
We're going to get ~14 additional source files with the USB PR,
and this is really needed to keep things from becoming a total pain.
Hiding and not implementing the copy constructor is a pre-C++11 thing.
It should also be noted that a copy constructor, as defined by the
language, contains a const qualifier on its parameter, so this wouldn't
have prevented copies from being performed.
Now that everything has been changed to use the new structs, the old
methods and structs can be removed.
And while I was changing the base device class, I also moved the
"unsupported command" code to a separate function. It was pretty silly
to copy the same 3 lines for ~5 commands.
This adds well-defined structs that are responsible for parsing
resource requests, instead of duplicating the logic and offsets all
over IOS HLE. Command handler functions are now passed parsed requests
instead of a command address.
This may not seem like a very important change, but it removes the
need to remember all of the struct offsets or copy/paste existing
struct request variables. It also prevents nasty bugs which have
occurred in the past, such as parsing an ioctl as if it were an ioctlv
(that's way too easy to do if you pass command addresses directly);
or writing something to 0x0, which can easily happen by mistake with
a close handler that can be called with invalid command addresses.
Bonus changes:
- The return code is not an obscure Memory::Write_U32 anymore, but an
explicit, more obvious SetReturnValue() call. (Which correctly takes
a s32 instead of a u32, since return codes are signed.)
- Open handlers are now only responsible for returning an IOS ret code,
and Close handlers don't return anything and don't have to worry
about checking whether the request is a real one anymore.
- DumpAsync was moved to the ioctlv request struct, because it did
not really make sense to make it part of the IOS device and it only
works for ioctlvs.
All current usages have been removed; they will be readded in a
later commit.
As of this commit, nothing uses the structs yet. Usages will be
migrated progressively.
Hiding and not implementing the copy constructor is a pre-C++11 thing.
It should also be noted that a copy constructor, as defined by the language,
contains a const qualifier on its parameter, so this wouldn't have
prevented copies from being performed.
It also follows that if the copy constructor is deleted, then copy
assignment should also be forbidden.
wxChoice controls don't display any titles.
By the way, why is the file called DebuggerPanel.cpp
even though it implements the Video debug panel specifically?
The current implementations do many things wrong but work well enough to
run the Dragon Quest X installer until the very end. The game itself
crashes when being launched from its System Menu channel unfortunately
so it is hard to verify whether the install properly worked or not.
There are plenty of "TODO(wfs)" sprinkled around this codebase with
things that are knowingly done wrong. The most important one right now
is that content extraction is done by buffering everything into memory
instead of properly streaming the data to disk (and processing
asynchronously), which causes freezes. It is likely to not cause any
practical issues since only the installer and the updater should use
this anyway.
Without this, attempts to savestate std::set will fail with an error
about dropping the const qualifier.
<Lioncash> leoetlino: I'll try to break it down: So, when you do a
ranged-for on a container, it's essentially syntactic sugar over begin
and end iterators. std::set is an associative container where the key
type is the same as the value type, and so it's required that all
iterator functions return constant iterators. If this wasn't a
requirement, it would allow changing the ordering of elements from
outside of the set's API (this is bad).
This attempts to make some bit arithmetic more self-documenting and also
make it easier during review to identify potential off-by-one errors by
making it possible to just specify which bits are being extracted.
Functions both support the case where bits being extracted can vary and
fixed bit extraction. In the case the bits are fixed, compile-time asserts
are present to prevent accidental API usage at compile-time.
e.g. Instead of shifting and masking to get bits 10 to 15,
Common::ExtractBits<10, 15>(value) can just be done instead.
There are several things wrong with this implementation. The first being
that since we still don't have a proper ticket/tmd handling library, we
hardcode offsets once again to fetch TMD fields. The second being that
we don't stream data to the disk and we buffer everything in memory. The
third being that we don't properly fetch the content index for
decryption, which is prone to breaking.
But hey, it works well enough to install the DQX channel!
This library implements basic parsing support for some of the IOS ES
formats we need to extract data from. Currently only implements TMD
functions, but some ticket handling functions from DiscIO should likely
be moved here in the future.
These two functions load either a signed ticket or a raw ticket from the
emulated NAND.
The ticket signature skip is refactored out of the ticket writing in
order to be usable by the raw ticket reading function.
Refactor the existing DiscIO::AddTicket to not require the caller to
pass the requested title ID. We do not have the title ID in the ES case,
and it needs to be extracted from the ticket. Since this is always a
safe operation to do (title ID is always in the ticket), the
implementation is made default.
This constant isn't particularly helpful, mainly because it's not
applicable to all DSP instructions. Some instructions don't have encoding
space for registers, and not all instructions that do encode registers
have one at the first five bits.
This change also has the benefit of removing all includes to the
interpreter within the JIT code, which keeps them fully separate from one
another. Changes to the interpreter header won't require some of the JIT
code to be rebuilt.
Dolphin is able to generate one with all correct default settings, so
we don't need to ship with a pre-generated SYSCONF and worry about
syncing default settings.
Additionally, this commit changes SysConf to work with session SYSCONFs
so that Dolphin is able to generate a default one even for Movie/TAS.
Which SYSCONF needs to be touched is explicitly specified to avoid
confusion about which file SysConf is managing.
(Another notable change is that the Wii root functions are moved into
Core to prevent Common from depending on Core.)
Reset():
We only need to close IOS devices which were opened, and we can do that
simply by iterating over s_fdmap and closing any opened device.
With this change, s_device_map can be cleared at once.
SetDefaultContentFile():
We can just use s_es_handles which is guaranteed to contain three valid
ES devices. Gets rid of a downcast.
Since the Open command won't ever return with the stub, there's no way
we will get a Close/IOCtl/IOCtlV for it, so we don't have to
implement it at all.
is_hardware is an obscure name (what does hardware mean?) and it forces
us to assume that anything that !is_hardware is a FileIO device. This
assumption prevents properly restoring OH0 child devices (which will be
implemented in the USB PR), so this commit replaces the is_hardware
bool with a device type.
Confirmed by a hardware test and a quick diassembly of /dev/es.
I'm not aware of anything that opens several ES handles, but
technically, this fixes a small inaccuracy in IOS HLE.
For IOCTL_STM_EVENTHOOK, IOS checks if there is already an event hook
to prevent overriding an existing event hook message with a new one,
without first releasing it.
Currently, the country is always overridden depending on the Wii
language setting. This makes it impossible to change the country
independently from the language, unlike on a Wii, since a language
will always be associated to an unique country (which is hardcoded
in Dolphin's codebase).
This behaviour was added in c881262 and changed in PR 4319 to happen
every time emulation is started. It doesn't seem to be needed anymore,
as a quick testing shows that a Japanese system menu is able to load
in Japanese even with the region set to France, or anything other than
Japan in fact. So what this commit changes is drop this code.
Fixes issue 9884.
Removes #defines which have been unused for years and cleans up
naming.
This also changes IPC_REP_ASYNC to simply IPC_REPLY because it turns
out it's actually not specific to async replies, but used for all
command replies.
- Use an enum instead of defines.
- Only use the FS_ prefix for return codes which are actually related
to FS stuff, not for everything.
- Remove duplicated error codes and clean up the names.
Size is internally stored as a size_t, so having an int parameter
would cause implicit sign-conversion from a signed value to an
unsigned value to occur.
This removes Open() and Close() functions from devices whenever they
did nothing more than the base class (setting m_Active, returning a
default reply).
Also, since IOS close commands practically always return FS_SUCCESS,
writing the return code is moved to HandleCommand() in WII_IPC_HLE,
which has two benefits: it's not duplicated all over the place
(so people will not forget it) and it gets rid of having to check
the force parameter, since HandleCommand() is always called for
real IOS commands, so command_address is guaranteed to be valid.
It looks like at some point Dolphin device IDs coincided with IOS file
descriptors, but this is not the case anymore, so keeping those
WriteReturnCode(GetDeviceID()) in every single IOS HLE device,
as if the device ID was used as IOS fd, is both unnecessary
and confusing.
Jan 04 22:55:01 <leoetlino> fwiw, it looks like there are new warnings in the RegCache code
Jan 04 22:55:04 <leoetlino> Source/Core/Core/PowerPC/Jit64/FPURegCache.cpp:13:33: warning: declaration shadows a variable in the global namespace [-Wshadow]
Jan 04 22:56:19 <@Lioncash> yeah, the jit global should have a g_ prefix.
This fixes shadowing warnings and adds the g_ prefix to a global.
Other settings options are nouns rather than verbs so this change makes the configuration option consistent with others. Also makes the menu option label the same as the windows title.
The constructor shouldn't be used as a dumping ground for all UI-related
initialization. Doing so makes it somewhat more difficult to reason about
how certain UI elements get created. It also puts unrelated identifiers in
the same scope.
This separates the UI creation out so code relevant to each component
is self-contained.
We don't really have to keep track of device opens/closes manually,
since we can already check that by calling IsOpened() on the device.
This also replaces some loops with for range loops.
Certain parts of the standard library try to determine whether or not a
transfer operation should either be a copy or a move. The prevalent notion
of move constructors/assignment operators is that they should not throw,
they simply move an already existing resource somewhere else.
This is typically done with 'std::move_if_noexcept'. Like the name says,
if a type's move constructor is noexcept, then the functions retrieves an
r-value reference (for move semantics), or an l-value (for copy semantics)
if it is not noexcept.
As IOFile deletes the copy constructor and copy assignment operators,
using IOFile with certain parts of the standard library can fail in
unexcepted ways (especially when used with various container
implementations). This prevents that.
'operator void*' is basically a pre-C++11-ism that was used, as C++03
only had the notion of implicit type-conversion operators, but not explicit type
conversion operators (allowing implicit conversion of a file handle to
bool can go downhill pretty quickly).
ExecuteCommand was becoming pretty confusing with unused variables
for some commands, confusing names (device ID != IOS file descriptor),
duplicated checks, not keeping the indentation level low, and having
tons of things into a single function.
This commit gives more correct names to variables, deduplicates the
device checking code, and splits ExecuteCommand so that it's
easier to read.
It's worth noting that some device checks have been forgotten in the
past, which has caused a bug (which was recently fixed in 288e75f6).
GCMemcard is only used outside of the core and has
no real reason to use the core's RTC. GetEmulatedTime
isn't designed to be called when the core isn't running.
Should fix https://bugs.dolphin-emu.org/issues/9871
From what I can tell, the emulated GPU places (0,0) at the lower left of
the image, and we were generating texture coordinates so that (0,0) was
at the upper-left in the expansion geometry shader, causing textures
used by point sprites to be flipped vertically.
Fixes the upside-down A button in Mario Golf.
Since in this case we're setting it based on the state at record start
time, not when a register is loaded, UseMemory would not be called, so
this could potentially wipe out texture memory that was valid.
This should ensure that when playing with loop enabled, the first frame is
in the same state each time. There is potentially still issues when the
start frame is set to something other than zero, but I'm not sure how we
could work around this without capturing the entire state on each frame.
Doing it from the add dialogs instead would prevent the call to these dialogs outside of a breakpointWindow which would be necessary for hotkeys binding.
Instead of needing different switch cases for
converting countries to regions in multiple places,
we now only need a single country-to-region switch case
(in DiscIO/Enums.cpp), and we get a nice Region type.
This also makes it a strongly-typed enum.
Considering that the flushing mode is a trait/behavior for the register
cache, it doesn't really make sense to have the enum separate from it.
This also has the benefit of removing constants from global scope.
This is done to not have the device combo box be too small in width when making the main sizer fit into the window. Not fitting the sizer would alternatively break Hidpi so it was best to just add an empty sizer to workaround this problem.
I think it's best to remove these if we are going to be adding new hotkeys since these would work no matter what so I can simply make these the default one instead.
This was kind of a pointless function, considering the parameter wasn't
used at all, so the other Flush() function could have been just directly
used instead.
Windows-1252 was sometimes being referred to as ASCII or ANSI
in Dolphin, which is incorrect. ASCII is only a subset of
Windows-1252, and ANSI is (rather improperly) used in Windows
to refer to the current code page (which often is 1252 on
Western systems, but can also be something entirely different).
The commit also replaces "SJIS" with "Shift JIS". "SJIS"
isn't misleading, but "Shift JIS" is more commonly used.
GetName() creates a new evdev device which calls tons of ioctls. But the
main culprit is close() which for input devices appears to be a slow
path in the kernel.
This commit reduces PopulateDevices() by 50% on my laptop, but ~730 ms
is still ridiculously slow for something that isn't needed right away.
We can't rely on the OS returning files and directories
in a deterministic order, so we should sort them on our own
if we want VolumeDirectory to work for movies and netplay.
This fixes a bug which caused Movie (input recording or playback) or
netplay not to be stopped. DolphinWX previously triggered a STM power
event, and then the STM directly stopped the emulation; the code
which stops Movie/Netplay was completely skipped.
This is fixed by moving it /before/ sending the shutdown event.
This allows removing DSPCore and DSPTables includes from the header file.
Doing allows resolving quite a bit of indirect includes that were present
throughout the DSP source files.
Another plus with this is that changes to the DSPEmitter don't require an
almost total rebuild of all DSP source files. The underlying reason for
most of the files being rebuilt it because DSPMemoryMap is used quite
extensively, however its header includes DSPTables.h. DSPTables.h includes
DSPEmitter.h as it uses the DSPEmitter type in a typedef. So any change to
the emitter would propagate through the DSPMemoryMap header. This will no
longer happen.
This is actually used as the DSP JIT, so this should be with the other JIT
source files.
This commit also makes it so changes to the JIT emitter don't require
recompiling all of the DSP core (i.e. changing the JIT won't require the
interpreter to be rebuilt).
Jit64 inherits from Jitx86Base which inherits from JitBase. JitBase
contains jo and js, which are instances of the JitOptions and JitState
structs. Because of the inheritance, there's no actual need to access the
jit global in order to get to these instances. They're already accessible
via the class hierarchy.
This happened when the geometry shader was disabled, and the uniform
buffer was grown to a larger size. The update would be skipped, leaving
the old buffer to be included in the descriptor set.
OnBootDrive used the "drives" member std::vector for drive paths, but
since PR #4363, this vector is not populated anymore, so we were
accessing it out of bounds.
Actually, drives was not needed in the first place, since we can
get the wxMenu from the event, and from there, get the label directly.
Much of Jit64Util consists of essentials, not utilities. Breaking these
out into their own files also prevents unrelated includes from being
present near other classes.
This also makes it easier to find and change certain components of the
x86-64 JIT, should it be necessary.
These provide the same semantics, however aggregate initialization
doesn't force the structs to be trivially copyable. memset, on the other
hand, does.
JUTWarningConsole_f calls vprintf, but in a way we currently don't
handle (which messes up the printed message). However, it is a standard
debug print function, so we can directly hook it instead of waiting for
the vprintf call.
This is necessary to fix debug output in a few games now that vprintf
is properly detected in more games.
This is more logical as the mic is plugged into an EXI slot so it should be configured via the GameCube config dialog. This also allows to pass the right port number for the new dialog.
This also moves the pipeline and descriptor set layouts used for texture
conversion (texel buffers) to ObjectCache, and shares a binding location
with the SSBO set.
Makes the information panel self-contained.
This was done first, as opposed to isolating the GameConfig panel--the
first panel in the group--as this panel had code all over the place in
ISOProperties, so I figured it'd be best to fix this one up first.
These disc images are encrypted and signed using a different set of keys.
We only care about the master key, so we check the signature issuer. If
it matches the debug issuer, then we'll use the RVT-R key. Otherwise,
the previous set of common and Korean keys are used.
The SDL backend crashes when you close a joystick after SDL_Quit has
been called. Some backends don't need to be shutdown and
re-initialized everytime, we can just ask to enumerate devices again.
It's questionable whether ES_LAUNCH should write *anything* to the
command structure at all, ever, given that it never actually returns
it back through the mailbox. But it *definitely* shouldn't write
anything to it if it has just launched a DOL, because otherwise it might
clobber code/data from the just-loaded application.
When booting "cooked" executables, BATs should already be set up and
enabled. They should only really be disabled when booting NAND contents
in real mode.
Should we ever introduce anything else that has to be done when a command
buffer is executed (e.g. invalidating constants from previous commit), we
don't have to update all the callers.
This could happen because the vertex memory was already committed, if a
uniform buffer allocation failed and caused a command buffer to be
executed, it would be associated with the previous command buffer rather
than the buffer containing the draw that consumed these vertices.
This was happening when a fence wait happened mid-frame. The data written
between the fence being queued and the allocation occuring was incorrectly
assumed to be consumed by the GPU.
Hotkeys
Make a new class that inherits from InputConfigDialog with a specialised constructor. The changes are mainly the top portion and it now uses tabs to categorise the hotkeys.
Redo the GCPad configuration dialog
The layout is similar, but it now allows flexibility to change it more easily.
Redo the GC Keyboard configuration dialog
Same layout.
Redo completely the Wiimote configuration dialog
Separated the controls into 2 tabs to make them less imposing overall.
Redo the Nunchuk configuration dialog
Similar layout, except for 2 control group sizers.
Redo the Classic controller configuration dialog
Same layout.
Redo the Guitar input configuration dialog
Stacked 2 sets of group together.
Redo the Turntable configuration dialog
More stacked groups and the window is much less wide.
Just setting up a switch on the type so that different dialogs can be instantiated. This also makes the extension type an enum because I don't see why not here and finally, it removes ControlGroupSizer. This removal allows to not dynamically generate the UI, but instead, let the specialised constructors do the layout.
Removed the unecessary forced tabbed layout, removed the layout part of the constructor and remade some method in preparation for tabbed styled input dialog such as the new hotkey configuration one. It breaks every inputconfigDialog, but this will get fixed in the next commits.
Also moved to a folder since there will be many more files created in the next commits so it gives better separation.
Making changes to ConfigManager.h has always been a pain, because
it means rebuilding half of Dolphin, since a lot of files depend on
and include this header.
However, it turns out some includes are unnecessary. This commit
removes ConfigManager includes from files which don't contain
SConfig or GPUDeterminismMode or GPU_DETERMINISM (which means the
ConfigManager include is not used).
(I've also had to get rid of some indirect includes.)
Prevents path traversal without needing an absolute path
function, and also improves accuracy (character sequences
like ../ appear to have no special meaning in IOS).
This removes the creation and usage of /sys/replace,
because the new escapes are too complicated to all
be representable in its format and because no other
NAND handling software seems to use /sys/replace.
This reverts commit 141f3bfb3a.
The implementation of getting absolute paths wasn't working
on non-Windows systems, which is a huge problem for IOS HLE.
For hotkeys, changed HotkeyManager to allow to get and make partial groups of hotkeys.
Also preserved the old configuration naming scheme for the ini, this is done to preserve compatibility with the older groups structure.
Add the ability to get GCPad control groups
Used like the HotkeyManager methods, this is used for the new GCPad configuration dialog.
Add the ability to get groups of Keyboard input
Same reasons as the previous ones.
Add ability to get groups of Wiimote input
Add the ability to get extensions group
This needed to pass to 3 classes. Will be used for their respective dialogs.
I know there is already #3521, but it currently needs a rebase and I
needed to add something to IPC_HLE_Device properly, that is, without
putting everything in the header, so this commit cleans up
IPC_HLE_Device first. (And only IPC_HLE_Device: the rest will still
be handled by #3521.)
Also fixes a few indirect includes (removing unused header includes
from IPC_HLE_Device.h broke building)
This is something that was copy-pasted across the IPC_HLE code
(because it's often used). Since all of the duplicated pieces of code
do the same thing as the previous EnqueueReply, except that they also
write to command_address + 0 and + 8 (to write the correct reply type),
this commit changes EnqueueReply to do that instead of having it
duplicated all over IPC HLE.
It was apparently causing heavy slowdowns on game even though it wouldn't spam much, probably caused by the amount of additional check caused by the logs levels changes.
This is mainly for potential Android fifoci usage, and thus is not
exposed anywhere in the UI. To enable, set DumpFramesAsImages under
Settings in GFX.ini.
When the emulated BT device is created, m_HCIEndpoint (which is a
CtrlBuffer)'s m_cmd_address is not initialised to 0. So it ends up
being a random value. This is normally not an issue… but the
emulated Bluetooth code relies on m_cmd_address to know whether the
HCI endpoint is still valid.
This is a problem with ES_Launch, because the bt_emu class is
destructed and re-constructed, and while m_cmd_address is still
uninitialised, the ES_Launch code disconnects all Wii remotes,
which triggers a HCI event and hence the bug.
Instead of resetting two command buffers, now we only have to call
vkResetCommandPool once at the start of a frame.
NV's recommends using one pool per frame/thread. May offer a very small
boost in performance on some systems.
%n writes to a pointer that's provided as a parameter.
We didn't have a custom implementation of this before,
meaning that %n would trigger a write to the host
memory instead of the emulated memory!
The bounds checks in IOCtl were using 0x200 as the size of
m_Registers, which is more than the actual size, 0x200 / 4.
This commit turns m_Registers into an std::array to allow
for a correct and obvious way of getting its size.
anv seems to set this to zero, which is fine according to the spec, but
we were using it as a maximum, which was resulting in a swap chain
without any buffers being created.
This fixes the screenshot stutter, as this needs more than a frame.
So we won't stall on the png writing at all until emulation stops or
a new screenshot is requested.
This increase the performance of good backends a bit, but slows down the bads one a lot.
Let's fix those backends instead of forcing stupid memcpy in the common code.
Makes for a cleaner separation of functionality, as well as removing
multiple includes from the main header file. It also gets a bunch of
structs and enums out of the global namespace.
Coincidentally, this also gets rid of an indirect include cycle that
could have broken compilation of Core.cpp in the future, since it was
relying on IPC network includes to resolve functions in Common/NandPaths.h.
This makes it easier to separate out the individual net classes in a
follow-up. Separating these out would also make it less of a pain to
figure out what's going on, since you wouldn't need to sift through 1000+
lines of code.i
This used an invalid pointer, which was only valid within AddFrame.
This drops a feature which shall dump the last frame as it might was dropped before.
A good implementation however should "overwrite" the last frame if the time matches.
But this needs to delay every frame a bit.
This eliminates public usage of the GetMenuBar() function in CodeWindow.
The benefit of this is it also gets rid of the need to perform direct
access across the config dialog and the main frame. It also gets rid of
the use of the main_frame global.
GetMenuBar() will be removed entirely from CodeWindow in a follow-up that
also removes any related remnants of code made obsolete with its removal.
Gets rid of more menu-related code from CodeWindow and puts it back in
CFrame where it belongs.
This turns the previous menu update function within CodeWindow into one
that simply updates the debugger font for its managed controls. It also
improves how the font is actually updated. Previously, fonts would change,
however this wouldn't actually reflect onto the respective controls until
a refresh or update event occurred. Since codeview, callstack, symbols,
callers, and calls windows are all managed by a wxAuiManager instance,
calling Update() on it after the font has been set will reflect font
changes immediately.
There's not a lot of point in passing these around or storing them
(texture cache/state tracker mainly) as there will only ever be a single
instance of the class.
Also adds downcast helpers such as Vulkan::Renderer::GetInstance().
In the code view, it would never say r1 or r2, but rather sp (stack pointer) and rtoc (register of the table of content) respectively. In the register view, all it says is the register number. This is an inconvenience considering it might not be obvious which register belongs to which of these terms.
Also make r13 named the "sda" for small data area with the same convention as above.
This not only fixes a regression where toggling a breakpoint using the CodeWindow would cause a Center PC, but it also removes several redundant JumpToAddress(PC) calls.
On Linux, the FindFocus method from wx simply doesn't work, it would on some environment report that dolphin has the focus while it doesn't have it. This is why an alternative method has to be used which is to set a focus flag whenever the render frame gets activated.
Some adapters don't have the correct interface class, so they are not
recognised as Bluetooth adapters. It seems that apart from hardcoding
VIDs/PIDs (which is how it's done in the Linux kernel, and which I'm
not very fond of), there is no other way to detect if a device is a
Bluetooth adapter or not.
This change makes Dolphin skip the descriptor check when trying to find
a usable adapter for Bluetooth Passthrough if the use of a specific
adapter was forced; it is assumed that the user knows what they are
doing if they hand-edited their config file.
This allows such adapters to be used.
The usage of "Wii Remote" and "Wiimote" in the interface is inconsistent. "Wiimote" is also not a real word nor is it an official product name. Therefore I have changed instances of "Wiimote" in the UI to instead say "Wii Remote". I also made a couple of minor grammatical changes as well.
This is mostly a resubmission of #4338 but there are some minor other changes as well.
I didn't know that telling that you don't schedule from the CPU thread prevents an assert because it by default assumes you use the CPU thread, but in the case of ClearCacheThreadSafe, it's used from the GUI thread.
Commit 4969415 modified calls to GetInterpolationQualifier, but mistakenly changed the order of some boolean parameters: GetInterpolationQualifier(true, false) was changed to GetInterpolationQualifier(…, false, true).
Should fix#9783.
Currently, `g_controller_interface` is initialized and shut down by each
of `GCKeyboard`, `GCPad`, `Wiimote`, and `HotkeyManager`.
This 1) is weird conceptually, because it necessitates passing a pointer
to the native window to each of those classes, which don't need it, and
2) can cause issues when controller backends are initialized or shutdown
multiple times in succession.
For Wii graceful shutdown to work, the emulated software has to open
the STM event hook and install a hook. Without this, there is no way
to inform them about the shutdown, so trying to do a graceful shutdown
and requiring the use of the shutdown fallback (exiting a second time
to force) is pointless.
Previously Dolphin would only exit if the main window is closed,
and Confirm on Stop is enabled.
This makes Dolphin's behaviour more consistent by always exiting
if the main window is closed or on shutdown signal.
s_dvd_thread_done_working makes the logic more complicated,
and degasus pointed out a race condition that can happen if
the CPU thread calls WaitForIdle right in between the DVD
thread executing done_working.Set() and done_working.Reset()
while there is work left to do. To avoid this, let's just get
rid of s_dvd_thread_done_working. It's a relic from the old
DVDThread design. Thanks to the last few commits, WaitUntilIdle
only gets called rarely (disc change and savestate), so it's
not a problem if WaitUntilIdle ends up being slower.
This is a preparation for adding a queue to DVDThread.
Currently, s_read_request and s_read_result act somewhat like
queues that only can contain one object.
This would previously fail to compile when included in files that do not
include FileUtil.h due to lack of a type declaration.
This moves the constructor and destructor into the cpp file in order to
satisfy the requirements of unique_ptr construction and deletion. That is,
unique_ptr requires a concrete type at the point of construction and
destruction. If the constructor or destructor is left in the header, then
at the point of construction or destruction, IOFile will still be
considered an incomplete type, as unique_ptr's deleter will still only be
able to see the forward declaration, which it can't use.
Unless I'm misreading the code, it doesn't look like this serves any
purpose, and is only polluting the logs.
_Unimplemented_Device_ looked like a device name that was picked to
be used somewhere else in Dolphin, but this doesn't seem to be the case
since 2012 (d95e31a removed the only other usage of this fake device).
Unifies the creation of all the menus into the main frame class.
Now it isn't spread out across the main frame and the code window.
This doesn't alter the placement of the handling functions, as this would
involve unrelated changes, since it would require modifying where
window-related variables are placed. This will be amended in a follow up
changeset.
Keeps related menu items together based on top level menu. This will be
more convenient in the future when debugger menu bar item handling is
moved to CFrame, as it won't be a huge amount of code in one function.
This also makes it easier to locate menu bar code whenever it needs to be
changed.
4319 made Dolphin not read/write directly to the SYSCONF and read
settings from the SYSCONF at boot, and only write Dolphin settings
to the SYSCONF at emulation startup.
However, this also made it a bit confusing, because if settings were
changed, then Dolphin was exited without starting a game in between,
the settings wouldn't actually get persisted. This is fixed by
syncing Dolphin settings with the SYSCONF when Dolphin exits.
Instead of directly reading/storing settings from/to the SYSCONF, we
now store Wii settings to Dolphin's own configuration, and apply them
on boot. This prevents issues with settings not being saved, being
overridden and lost (if the user opens a dialog that writes to the
SYSCONF while a game is running).
This also fixes restoring settings from the config cache after a
graceful shutdown; for some reason, settings were only restored
after a normal shutdown.
Fixes issue 9825 and 9826
Using u8 as indexers is kind of silly, since the rest of the public API
essentially uses int for this sort of thing. Changing these to int also
gets rid of quite a few implicit truncations.
This also allows for getting rid of similar silliness in the netplay API.
There's no official implementation of the Vulkan API,
and Dolphin currently isn't set-up to work with the
single, commercially-available third-party implementation.
This is done to remove confusions among potential debugger users and to also make it more accurately tell what this feature is actually doing. Despite being true that it is using a memcheck (and it certianly checks that memory), the idea being to break on a memory access isn't really obvious especially considering that memchecks are also used in full MMU emulation to handle exceptions. It also doesn't help that memchecks are now supported in every builds.
It also changes the corresponding log because this log would be wanted by the user which means it should be more obvious that it was caused by the "memory breakpoint".
This is an issue because a driver may have to maintain two copies of a
texture if it batches all uploads together at the start of a frame.
In the Vulkan backend, we do something similar to avoid breaking out of a
render pass to copy a texture from the streaming buffer to the destination
image.
This was causing issues in the sms-bubbles fifolog, where an EFB copy to
the same address of a previously-used texture caused the previous texture
to be re-used again for a different image later on in the frame, causing
the original contents to be discarded.
Using cmake and GCC, logs would contain the full file path when logging making logs lines unnecessarily long. This is solved by just removing anything before "/Source/Core/" (where / is whatever your OS uses to separated directory).
This happened when the source texture was an EFB copy, therefore it had
not been populated prior to the draw command buffer being executed, and
the conversion was occurring in the init command list.
Setting a single icon at a single resolution doesn't scale well,
Windows requires a 16x16 icon for the window and a 32x32/48x48 for
the taskbar. Providing all icons produces less pixellated results at
HiDPI.
Changes:
- MemoryWindow was cleaned up and gives more feedback on searches.
Some bugs were fixed as well:
- A complex bug that allowed tearing off tabs and opening multiple
copies of a debug panel which lead to segfaults
- Another segfault related to right-click menus on code/memory views
when those tools were floating in their own window.
Resolved "TODO" for Texture Cache safety, added explanation message.
Resolved "TODO" for default description, no longer uses default text for sizing
Fixed a memory leak in PostProcessingConfigDiag where it was never freeing any
of the objects it allocated in its constructor.
Minor design change to PostProcessingConfigDiag to give padding around elements
consistent with the rest of Dolphin's user interface (5px).
Changed the Cheat Search tab to disable the scan buttons while there is
not a game running and enable when it starts. Also added double-click to
create code to the result list.
Required a partial rewrite of the image loading code because it was working in
unscaled wxBitmaps. Needed to make it produce wxImages and scale them instead.
And related ARCodeAddEdit/PatchAddEdit.
Change ISOFile to use wxImage instead of wxBitmap since bitmaps require
a screen context and banner images have a fixed resolution.
Some OSD messages were displayed in RenderBase.cpp using global variables and some code duplicated
in OnScreeDisplay.cpp.
Now all messages are displayed using functions in the OSD namepace.
* OSDChoice and OSDTime global variables are gone
* All OSD logic is kept at the same place
* All messages are properly aligned
* Clean characters for all OSD messages

There was a bug that caused MemoryView to indirectly cause a segfault;
the simplest way to reproduce it is 1) start a game; 2) stop the game;
3) click on the Refresh button and watch Dolphin segfault.
This commit fixes it by only calling PowerPC::HostIsRAMAddress when
emulation is running.
It doesn't make much sense to prefix g_ to static variables and for
some to be completely unprefixed.
Also renames a lot of other variables for the new conventions
This fixes an issue where the Bluetooth info section could be fully
filled up by syncing 5 Wiimotes in passthrough mode then switching to
emulated Bluetooth; emulated Wiimotes were then unable to be used.
The "real" SYSCONF section is now backed up before being replaced with
a blank section that the emulated BT adapter can always fill with 5
Wiimotes without issues.
This backup is restored by the passthrough code, instead of during
the Bluetooth mode switch because this should be done regardless of the
user interface, and even without UI (if the config file is edited
manually).
Homebrew programs seem to rely on getting a reply to the vendor
specific commands, without which Bluetooth initialisation will never
complete.
This vendor-specific command is typically used to patch the Wii's
Bluetooth module, so the replies are only faked when the passed through
adapter is not a Wii Bluetooth module.
This stores the address of paired devices and associated link keys.
It is needed because some adapters forget all stored link keys when
they are reset, which breaks pairings because the Wii relies on the
Bluetooth module to remember them.
It doesn't fix adapters that can't remember any link key
at all and always return 0 for the number of stored/written link keys.
For those adapters, there is no fix.
This also improves the usability of passthrough mode for adapters that
already work, since pairings will now keep working even if the link
keys get cleared by something else (for example by the host Bluetooth
stack).
The ControllerConfigDiag design was getting confusing, so more
significant changes needed to be done.
Firstly, the GC controller and the Wiimote section layouts have been
aligned for consistency.
The Balance Board source chooser is a checkbox.
The "general settings" that affect the SYSCONF have been moved to the
Wii pane in the Config dialog. It makes more sense because those
affect the Wii's settings in the NAND, unlike the other options.
Another reason for moving it is that the Controller Config Dialog was
getting pretty crowded, and the whole section is disabled when
emulation is running, which is wasted space.
The Wiimotes section is now organised by two radio buttons. One is for
the Passthrough Mode, with sync/reset buttons under it; the other is
the emulated Bluetooth mode, which still has the regular Wiimote source
choosers, the Continuous Scanning controls and the Enable Speaker Data
option (which only applies to the emulated BT mode).
Hopefully this should make things a bit clearer and look cleaner.
(This is a monolithic commit because separating UI changes is hard)
Apparently, Nintendo's Bluetooth stack expects the ACL packet buffer
size to be limited to 10.
Reporting anything higher than that could cause memory corruption,
which can result in warning messages in the logs ("event mismatch"),
and more annoyingly, random disconnects.
Thanks to shuffle2 for the fix!
This adds the ability to passthrough a whole Bluetooth adapter and skip
the majority of the Bluetooth emulation code. We use libusb to send HCI
commands, receive HCI events and transfer ACL data directly to the
first adapter that is found or to a specific adapter (if configured to)
This is possible because the Wii's Bluetooth module is actually just
a pretty standard Bluetooth adapter…
…except for two vendor-specific commands, for which replies are faked,
and also for the sync button. This adds a hotkey that works in the
exact same way as the sync button would on a Wii: it triggers an HCI
event, which emulated software interpret as a command to perform
a BT inquiry.
This commit also changes the UI code to expose passthrough mode
and WII_IPC_HLE to be a bit more thread safe (for the device map).
This moves the unordered_map used to store connected Wiimotes IDs to
WiimoteReal, and makes the ID insert/erase logic common so we don't
have to duplicate this code in scanner backends.
The Balance board detection logic is already implemented in a simpler
way in Wiimote::IsBalanceBoard() (since hidapi also needs it).
Therefore, IOWin now only needs to check if a device is a Wiimote.
This is intended to make reconnecting Wiimotes easier with a DolphinBar.
Unfortunately, this change isn't enough as it doesn't always catch
disconnections for Wiimotes connected with a DolphinBar.
But it's better than nothing and eventually a disconnection will be
detected when something tries to write to the Wiimote, instead of never.
There is no other solution as the DolphinBar always exposes 4 HIDs even
when the associated Wiimotes are not connected.
We could try to detect this using the fake input reports sent by the
DolphinBar, but this only works for the first HID (probably because of
a bug in the firmware?), so this method is not an option.
If FindWiimotes() took more time than the UI shutting down, the scanner
would try connecting a Wiimote and sending an event to the UI code
long after it has shut down, which causes a segfault.
This fixes the race by ignoring any found Wiimotes during shutdown.
Normally this would have never happened, but it is possible with hidapi
since Wiimotes can be connected before Dolphin starts.
wxWidgets causes a segfault if Host_ConnectWiimote is called and we try
to create an event from the Wiimote scanner thread while the GUI is
still initialising.
Based on ca0c2efe7a. Credits go to flacs.
However, unlike the original commit, hidapi does not completely replace
the current implementations, so we can still connect Wiimotes with 1+2
(without pairing).
Also, it is only used on Linux and OS X for now. This removes the
advantage of having only one implementation but there is no other
choice: using hidapi on Windows is currently impossible because
hid_write() is implemented in a way that won't work with Wiimotes.
Additionally:
* We now check for the device name in addition to the PID/VID so we can
support the Balance Board and maybe third-party Wiimotes too. This
doesn't achieve anything with the DolphinBar but it does with hidraw.
* Added a check to not connect to the same device more than once.
Should fix a possible reference to deleted framebuffers, as well as fixing
the issues with the render area being correct if the game's source area
changes, or auto-scaling is enabled.
Same thing but allows both GeckoCode and Code to be utilized directly
without predicates for equality/inequality in stardard algorithms
The size check for std::vectors is unnecessary, as this is built into std::vector's operator==
Because of the way this works, randomly overwriting the handler
when loading a savestate will break things because of the
self-modifying nature of the handler.
GeckoCodes require address hooks which don't correspond to any
symbol in the symbol table. The hooks get deleted when repatching
the game because they did not persist across calls to
HLE::PatchFunctions.
Dolphin emulates GeckoCodes by fiddling with the CPU state when a
VI Interrupt occurs. The problem with this is that we don't know
where the PC is so it's non-deterministic and not necessarily
suitable for use with the codehandler.
There are two options: Patch the game like Gecko OS either directly
or using HLE::Patch, or use a trampoline so we can branch from any
PC even if it would otherwise not be valid. The problem with Gecko OS
patches is there are 10 of them and they have to be configured
manually (i.e. Game INIs to would need to have a [Core]GeckoHookType
property).
HLE_Misc::GeckoReturnTrampoline enables the Code Handler to be
entered from anywhere, the trampoline restores all the registers that
had to be secretly saved to the stack.
If the installation fails because codehandler.bin is missing or
unusable then Dolphin will try again every single frame even though
it's highly unlikely a disk file will have changed. Better to just
fail once then only try again when the active code set is changed.
Suppresses generating 60 log messages per second.
Turns out one of the magic numbers was very magic. The gameid is
an ad-hoc comm protocol with HLE_Misc to control the number of times
the ICache is reset.
The code table builder cuts off the end of codes that won't fit
after already writing part of it. That seems quite unlikely to
work the way anyone would find useful since the codes can contain
actual PPC instructions.
The active codes vector cannot safely be used outside the mutex,
move the lock out into RunCodeHandler. s_code_handler_installed was
also racing against SetActiveCodes since it's being written both
inside and outside the lock.
General cleanup. Add s_ prefixes, use constexpr, remove C casts.
Executing PPC code inside an external events callback is a bad idea.
CoreTiming::Advance does not support recursion properly which will
cause timing glitches. The interpreter has a slice length hack that
counters this but without it this would cause a 20000 cycles time
skip. It isn't clear what this was supposed to accomplish that just
changing the current PC would not. Changing the PC works fine.
Deleting instead of overwriting makes the INI cleaner.
Also, in case we change defaults in the future, users will
get the new default when using a new version even if
they have pressed the Reset button in an older version.
Makes the buffering code a bit more explicit (circular buffer, but
blocks until individual buffers get unqueued by OpenAL), and fixes a
bug in the startup of Super Mario Sunshine:
https://bugs.dolphin-emu.org/issues/9811
When standby mode is enabled, this causes games to ES_Launch the system
menu instead of directly asking IOS (the STM more precisely) to shut
down, which prevents graceful shutdown from working
(it'll appear to hang).
Dolphin never supported WC24 standby mode anyway, so this shouldn't
cause any issues. (This should be reverted if and when WC24 standby is
implemented…)
This adds support for triggering the power event (in the STM), so that
stopping emulation first triggers a shutdown event, which notably gives
emulated software time to save game data (issue 8979) and clean up
SYSCONF (to disconnect Wiimotes and update their state in the SYSCONF).
On the first press, the stop button/hotkey/whatever will trigger a STM
power event. On a second try, we will forcefully stop emulation, just
like how it was working before.
There was as far as I know no reason to put everything in the header.
Separating the declaration from the implementation reduces build
times in case the implementation is updated without changing
any declaration.
This is needed because for some reason the WSI for NV Vulkan drivers
doesn't return VK_ERROR_OUT_OF_DATE_KHR, so there is no other way to know
that a resize has occured apart from polling, which is a poor solution for
X11 (since it is blocking).
Considering there's a public method in the class using it, leaving the
definition in the cpp file can cause a linker error if any method outside
that cpp file calls it for one reason or another.
Single step: Fix an oddity when a breakpoint is hit at the beginning of a block, then after, a single step is performed and finally, hitting play, the breakpoint will be skipped even in the case when it would be hit again. This was done by using the interpreter version of single step. Also, remove some redundant update request.
Step over: fix some GUI lags.
Step out: Add consideration for conditional branching by checking the condition as the interpreter does. Now, every bclr instructions except those that changes the LR (because it would not be the end of the function) will cause the end of the step out and not just blr instructions. Also now stops if a bp is detected and finally, remove redundant GUI updates calls.
This also removes a superfluous draw call on the GUI as the codeView was refreshing twice per event to do so.
It was never used, even when the code tried to make sure it was initialised and passed correctly. This is a supplementary fix for the memCheck dialog as this option will now work correctly.
The old one wasn't very optimal because not only the user would likely want to enter an address instead of a range, but it also made entering just one address confusing (you had to have the same value on both start and end). Also, you should only chose one option between read, write or both, there is no point to not have any.
This is why I made more clear how to add an address and it is the default option using radio buttons and I also made the action flags and the flags to be radio buttons.
It looks like the debug output is also output as SJIS (similar to
OSReport text), so we need to convert it to UTF-8 to prevent it from
all showing up as �.
This doesn't fix all display issues, but fixes all SJIS/UTF-8 related
ones.
This changes GetSymbolFromName to not require the passed name to
completely match with the symbol name. Instead, we now match
against the stripped symbol name (i.e. only the function name).
This fixes a regression introduced by #4160, which prevented
HLE::PatchFunctions() from working properly.
This is the same as PR #3991, but for MainNoGUI.
nogui/headless will shut down cleanly on SIGINT and SIGTERM, just like
it would when closing the render window.
The default signal handler will be restored after a first shutdown
signal so a second signal will exit Dolphin forcefully.
These functions don't actually depend on any state from the class
instance, so they don't really belong in the header, and are just
an implementation detail.
Fixes the issue on macOS where quitting Dolphin from the Dock causes a
crash report (https://bugs.dolphin-emu.org/issues/9794). I'm not
exactly sure why this works, but it feels right and it turns out to fix
the problem.
It didn't really made sense to disable 2 logs levels in releases builds while the level LDEBUG should really be where logs that would impact performance be. Info should be logs that report potentially usefull information and debug should report info that would only be usefull in debug context as they are called very often. To make this work, a lot of info log would have to be made debug log.
It also avoid inaccurate logs level done due to not using debug builds. While searching through the code, I saw a ton of logs that should have been info log, likely done to avoid using a debug build (which shouldn't happen considering the level debug exists anyway).
The whole idea is to have more meaningful logs in release builds while maintaining minimal performance loss from choosing the highest level. This could potentially help to diagnose issues or to know more about what the emulator is actually doing.
The next commit aims to sort the log levels for this purpose.
clang-format really *wants* the two empty lines to be removed;
otherwise, it will always flag MemoryUtil as needing formatting changes
which is an annoyance when it is used as a git filter driver.

This adds a recenter control binding which allows recentering the
cursor when relative input is enabled.
(EnableSettingControl is renamed to avoid confusions.)
This makes the GUI show the settings that are loaded when the config
gets reloaded, instead of showing potentially outdated settings that
are not applied.
This adds an option to enable relative input for the Wiimote IR
as described in issue 9014.
Enabling it will result in the pointer not going back to the centre
and the inputs will control the direction, not the absolute position.
Also adds a Dead Zone setting which is really needed when relative
input is enabled to prevent the cursor from slowly drifting on
most controllers. (Note: the Deadzone setting has no effect when
relative input is disabled)
Call Advance at the start of each timing slice instead of the end.
Possibly fixed a bug where a slice would randomly branch straight
back to Advance() because the flags were not set to the right
values before branching to the dispatcher entrypoint.
This fix a double break bug when hitting a memcheck and hitting play on the same instruction it broke to earlier. The state is put back to CPU_RUNNING after.
Doing this forces the window to be drawn before reparenting it. It fixes the possibility of creating an empty floating window if the selected tab wasn't corespoinding to the window.
There might be a better way to highlight the options when adding the memory check, but for now, this works and the breakpoint list reports the right settings anyway.
These are needed for the next commit. I had to modify the implementation of the DSP one too, but since it basically isn`t used, I don`t think it matters much. These options only matters when adding one.
It wouldn't impact performance until at least one memcheck is enabled. Because of this, it can be used in release builds without much impact, the only thing that woudl change is the use of HasAny method instead of preprocessor conditionals. Since the perforamnce decrease comes right when the first memcheck is added and restored when the last is removed, it basically is all beneficial and works the same way.
All formatting are individual per registers and they all have one option to go back to their original hexadecimal form.
- GPR: signed integer, unsigned integer, float
- FPR: double
Also happened to come accross an issue where editing the PFR would ignore the higher 32 bits of the new value, this had to be fixed for the format to work.
The min-heap provides no ordering when the key is the same on 2
nodes. Disambiguate identical times by tracking the order items
were added into the queue.
Some games will set q to a different value than 1.0 through
texture matrix manipulations. It seems the console will still
do the division in that case.
This removes a Dolphin-specific patch to the wxWidgets3 code
for the following reasons:
* Calling wxWindowGTK::DoSetSize on a top-level window can end up
calling wxTopLevelWindowGTK::DoMoveWindow, which triggers an assert
because it is not supposed to be called for a top-level wxWindow.
* We should not be patching the wxWidgets code because that means the
toolbars will still be broken if someone builds without using the
WX that is in our Externals.
Instead, we now use a derived class for wxAuiToolBar and override
DoSetSize() to remove the problematic behaviour to get the same effect
(fixing toolbars) but without changing Externals code and without
causing asserts and other issues.
Now that our timings are much more accurate it doesn't look like we
need it anymore. And the instant ARAM DMA mode + scheduling fixes
ctually breaks ATV: Quad Power Racing 2 (causing all sorts of werid
bugs).
Fundamentally, all this does is enforce the invariant that we always
translate effective addresses based on the current BAT registers and
page table before we do anything else with them.
This change can be logically divided into three parts. The first part is
creating a table to represent the current BAT state, and keeping it up to
date (PowerPC::IBATUpdated, PowerPC::DBATUpdated, etc.). This does
nothing by itself, but it's necessary for the other parts.
The second part (mostly in MMU.cpp) is simply removing all the hardcoded
checks for specific untranslated addresses, and consistently translating
addresses using the current BAT configuration. Very straightforward, but a
lot of code changes because we hardcoded assumptions all over the place.
The third part (mostly in Memmap.cpp) is making the fastmem arena reflect
the current BAT configuration. We do this by redoing the mapping (calling
memmap()) based on the BAT table whenever it changes.
One additional minor change is that translation can fail in two ways:
either the segment is a direct store segment, or page table lookup failed.
The difference doesn't usually matter, but the difference affects cache
instructions, like dcbz.
For step over, it was updating twice which actually made the red display on the register view (when a register changes since) malfunction. Since it doesn't seem to be usefull to update before AND after the run, the one before the run was removed.
For step out, well, because there was no chances given for the thread to run as it is single stepping all the time, I only added a call to update after it was done.
Init cannot be called more than once because it registers the
CoreTiming callbacks, that trips the assertions and will cause
anyone with PanicAlerts disabled to crash.
CoreTiming gets restored before ExpansionInterface so CoreTiming
events need to already be registered before the save state loading
begins. This means that the callbacks must be registered
unconditionally instead of on-demand.
Replace adhoc linked list with a priority heap. Performance
characteristics are mostly the same, but is more cache friendly.
[Priority Queues have O(log n) push/pop compared to the linked
list's O(n) push/O(1) pop but the queue is not big enough for
that to matter, so linear is faster over linked. Very slight gains
when framelimit is unlimited (Wind Waker), 1900% -> 1950%]
Some compilers don't have an automatic abs() overload for floats.
Doesn't really matter if they use the integer variant here, but
it's better to be explicit about the fact that we're using floats.
Dolphin no longer lowers itself below the top window when opening.
Dolphin no longer draws garbage lines all over the game list.
Use the correct platform macros so Dolphin can actually find the
translation catalogs on Unix.
Both those in the code window and the ones that appears when the user select edit perpective. The one that isn't fixed by this is in edit perspective mode, when the user drags a panel out and it becomes a floating window.
When n was a multiple of 4, the old implementation would overwrite
the following register with 0.
This was causing Not64 to crash.
Thanks to Extrems for spotting this.
