Mainly concerns to building with Ninja, as that's what I tested it with.
Originally it would only prepend the first path with `/external:I`,
however all paths in the list have to be prepended with `/external:I`.
The MS documentation seems to support this, as it makes no mention of it
accepting a list.
This is probably the worst way to implement this, I am unfamiliar with
CMake.
It's always a good sign when the comments say "this will definitely
crash" and "I don't know if this is for a good reason".
Fixes https://bugs.dolphin-emu.org/issues/12762.
These GetPointer calls could cause crashes, in part because the
callers didn't do null checks and in part because GetPointer
inherently is unsafe to use for accesses larger than 1 byte.
The actual values don't matter since we overwrite all of the relevant fields, but other bits were not initialized (e.g. the top 12 bits of X10Y10), so the warning was semi-valid.
This piece of code is rather hard to understand, but my best guess
at what it's trying to do is that it tries to create opportunities
to skip writing CRs back to ppcState if we know that there are no
CR instructions (or branch instructions, etc) between an instruction
that writes to a CR register and the next blr. This is technically
inaccurate emulation, but as long as games don't do anything too
weird with their ABIs, I suppose it doesn't break anything.
So why do I want to get rid of it? Well, other than breaking some
hypothetical weird game, I imagine it could trip up people trying
to debug a game who are looking at the CR contents. And the code
is just plain confusing. (blr clearly doesn't write to CRs!)
Videocommon also depends on core, which resulted in linking errors (though I'm not sure why). Ideally, dolphintool woudln't depend on videocommon... but some stuff in core does.
Previously, EFB copies would be in the middle of other objects, as objects were only split on primitive data. A distinct object for each EFB copy makes them easier to spot, but does also mean there are more objects that do nothing when disabled (as disabling an object only skips primitive data, and there is no primitive data for EFB copies).
This also adds the commands after the last primitive data but before the next frame as a unique object; this is mainly just the XFB copy. It's nice to have these visible, though disabling the object does nothing since only primitive data is disabled and there is no primitive data in this case.
Turns out that most phones ship with a special Google version of
DocumentsUI instead of just using the AOSP version, despite the two
being pretty similar as far as I can tell. This change makes us
check for both package names instead of just the AOSP package name.
It became irrelevant in 952dfcd610, when the define was removed; now, the code the comment is referring to is in JitRegister.cpp, and oprofile is controlled by cmake.
My change in 867cd99 caused farcode to fill up much more than before.
Most games still ran fine, but certain games would have multiple
cache clears per minute, on top of being overall slow.
Maybe there's something prettier we can do about this than just
allocating more RAM, but we have the resource budget for making
Dolphin use more RAM, so I consider increasing the size of the
cache to be a good solution at least for the time being.
At least for Prince of Persia: The Forgotten Sands, 48 MB isn't
enough to stop the cache clears, but 64 MB is. (I only played the
game for a few minutes when testing, though.)
To do this, I had to decouple framebuffer fetch from shader blending. We need to be able to access framebuffer fetch input when using shader logic ops.
If InputConfig::LoadConfig() was called once with a non empty/customized config,
then called again after manually deleting the config (dolphin calls LoadConfig() every time it opens the mapping widget),
the second load would fail to clear the values on any non first EmulatedController and would instead keep the
previous config values despite it being deleted (while it would instead correctly default the first EmulatedController).
This is not a big bug though the code is better now.
Fixes bug: https://bugs.dolphin-emu.org/issues/12744
Before e1e3db13ba
the ControllerInterface m_devices_mutex was "wrongfully" locked for the whole Initialize() call, which included the first device population refresh,
this has the unwanted (accidental) consequence of often preventing the different pads (GC Pad, Wii Contollers, ...) input configs from loading
until that mutex was released (the input config defaults loading was blocked in EmulatedController::LoadDefaults()), which meant that the devices
population would often have the time to finish adding its first device, which would then be selected as default device (by design, the first device
added to the CI is the default default device, usually the "Keyboard and Mouse" device).
After the commit mentioned above removed the unnecessary m_devices_mutex calls, the default default device would fail to load (be found)
causing the default input mappings, which are specifically written for the default default device on every platform, to not be bound to any
physical device input, breaking input on new dolphin installations (until a user tried to customize the default device manually).
Default devices are now always added synchronously to avoid the problem, and so they should in the future (I added comments and warnings to help with that)
This fixes the bad rendering on the first frame when using the software renderer: the software renderer's Z buffer started out at 0, but most games clear it to 0xffffff instead; this means that things don't render correctly except for in the regions where the screen was cleared by an EFB copy earlier in the frame.
The system menu does clear the RTC flags, but we currently aren't updating the cache file, and since we clear them the system menu doesn't know to update the cache either. This means that launching a game via the system menu, and then launching a game directly and exiting via HOME will result in the system menu using an outdated cache and displaying the old game. This causes it to fail to launch the game on the disc channel (since it doesn't match the cache), resulting in it resetting (though it will ignore the cache after resetting). Not clearing the cache avoids this issue.
PNG_FORMAT_RGB and PNG_COLOR_TYPE_RGB both evaluate to 2, but PNG_FORMAT_RGBA evaluates to 3 while PNG_COLOR_TYPE_RGBA evaluates to 6; the bit indicating a palette is 1 while the bit indicating alpha is 4.
Fixes Bomberman Jetters in single core mode.
When single core mode pauses the CPU to execute the GPU
FIFO it greedily executes the whole thing. Before this commit,
Finish and Token interrupts would happen instantly, not even
taking into account how long the current FIFO window has
taken to execute. The interrupts would be effectively backdated
to the start of this execution window.
This commit does two things: It pipes the current FIFO window
execution time though to the interrupt scheduling and it enforces
a minimum delay of 500 cycles before an interrupt will be fired.
Netplay: Fix possible Wii save restore race condition between Netplay and CPU threads on game shutdown by making the Wii Save Sync data part of the BootParameters.
Being able to preserve the address register is useful for the
next commit, and W0 is the address register used for loads. Saving
the address register used for stores, W1, was already supported.
If a host register has been newly allocated for the destination
guest register, and the load triggers an exception, we must make
sure to not write the old value in the host register into ppcState.
This commit achieves this by not marking the register as dirty
until after the load is done.
This does this following things:
- Default to the runtime automatic number of threads for pre-compiling shaders
- Adds a distinct automatic thread count computation for pre-compilation (which has less other things going on
and should scale better beyond 4 cores)
- Removes the unused logical_core_count field from the CPU detection
- Changes the semantics of num_cores from maximaum addressable number of cores to actually available CPU cores
(which is also how it was actually used)
- Updates the computation of the HTT flag now that AMD no longer lies about it for its Zen processors
- Background shader compilation is *not* enabled by default
Removed useless locks to DeviceContainer::m_devices_mutex, as they were all already protected by m_devices_population_mutex.
We have no interest in blocking other threads that were potentially reading devices at the same time so this seems fine.
This simplifies the code, and I've adjusted a few comments which mentioned possible deadlock that should now be totally gone.
The deadlock could have happen if a thread directly called EmulatedController::UpdateReferences(), while another another thread also reached EmulatedController::UpdateReferences() within a call to ControllerInterface::UpdateDevices(), as the mentioned function locked both the DeviceContainer::m_devices_mutex and s_get_state_mutex at the same time.
The deadlock was frequent on game emulation startup on Android, due to the UpdateReferences() call in InputConfig::LoadConfig() and the UI thread triggering calls to ControllerInterface::UpdateDevices().
It could also have happened on Desktop if a user pressed "Refresh Devices" manually in the UI while the input config was loading.
Also brought some UpdateReferences() comments and thread safety fixes from https://github.com/dolphin-emu/dolphin/pull/9489
I haven't fully confirmed why the previous commit broke this,
but I imagine it's due to AfterDirectoryInitializationRunner
executing in a different order than before, resulting in
startRescan running before startLoad.
This decreases our APK size by a few megabytes. Most of the reduction
is from Java libraries that we only use small parts of. Code shrinking
gets rid of all the unused code from these libraries from the APK.
Because I highly value the ability to get stack traces that make
sense, I have specifically disabled obfuscation (automatic renaming
of symbols to short incomprehensible names).
I've only enabled code shrinking for release builds, purely because
I feel like the extra build time (30 seconds on my machine)
would be annoying when you want to make debug builds rapidly.
This commit changes the default value of Fast Texture Sampling to true, and also moves the setting that controls it to the experimental section of the advanced tab. This is its own commit so that it can be easily reverted when we want to default to Manual Texture Sampling.
Co-authored-by: JosJuice <josjuice@gmail.com>
Specifically, when using Manual Texture Sampling, if textures sizes don't match the size the game specifies, things previously broke. That can happen with custom textures, and also with scaled EFB copies at non-native IRs. It breaks most obviously by not scaling the texture coordinates (so only part of the texture shows up), but the hardware wrapping functionality also assumes texture sizes are a power of 2 (or else it will behave weirdly in a way that matches how hardware behaves weirdly). The fix is to provide alternative texture wrapping logic when custom texture sizes are possible.
Note that both GLSL and HLSL provide a fwidth (fragment width) function defined as `fwidth(p) = abs(dFdx(p)) + abs(dFdy(p))`. However, it's easy enough to implement this ourselves (and it makes the code a bit more obvious).
The benefit to exposing this over the raw BP state is that adjustments Dolphin makes, such as LOD biases from arbitrary mipmap detection, will work properly.
Gets rid some uses of the deprecated LocalBroadcastManager.
One note about the changes in GameFileCacheManager itself:
The change from compareAndSet to getValue followed by
setValue is actually safe, because startLoad and startRescan
only run from the main thread, and only the main thread ever
sets the flags to true. So it's impossible for any other thread
to change the flag in between the getValue and the setValue.
The past few Android releases have been adding restrictions
to what services are allowed to do, for the sake of stopping
services from using up too much battery in the background.
The IntentService class, which GameFileCacheService uses,
was even deprecated in Android 11 in light of this.
Typically, the reason why you would want use a service instead of
using a simple thread or some other concurrency mechanism from the
Java standard library is if you want to be able to run code in the
background while the user isn't using your app. This isn't actually
something we care about for GameFileCacheService -- if Android wants
to kill Dolphin there's no reason to keep GameFileCacheService
running -- so let's make it not be a service.
I'm changing this mainly for the sake of future proofing, but there
is one immediate (minor) benefit: Previously, if you tried to launch
Dolphin from Android Studio while your phone was locked, the whole
app would fail to launch because launching GameFileCacheService
wasn't allowed because Dolphin wasn't considered a foreground app.
These messages apply to the User directory regardless of
whether it's global or local, so we shouldn't specify "global".
Also changing "directory" to "folder", just for consistency
with "GC folder" in the same sentence.
Unlike with Android 11, there should be no downsides to doing
this, so we might as well get this out of the way early.
The main part of the work was already done in 5a1a642.
This should make C++20 and std::filesystem work. (Not that
we really can use std::filesystem much on Android since
it doesn't work with scoped storage...)
We implement this by first rounding to nearest integer using the current
rouding mode, then converting this value from floating point to an integral
value.
Prefer using eax to isolate the sign bit. This saves a byte when the
destination ends up as r8-15, because those require a REX prefix.
Before:
41 8B C5 mov eax,r13d
41 C1 ED 1F shr r13d,1Fh
44 03 E8 add r13d,eax
41 D1 FD sar r13d,1
After:
41 8B C5 mov eax,r13d
C1 E8 1F shr eax,1Fh
44 03 E8 add r13d,eax
41 D1 FD sar r13d,1
This function was deprecated in ffmpeg in January[1], while its
replacement got introduced in 2015[2], so now might be the time to start
using it in Dolphin. :)

This moves the only direct call to zlib’s crc32() into its own
translation unit, but that operation is cold enough that this won’t
matter in the slightest. crc32_z() would be more appropriate, but
Android has an older zlib version…
This was originally intended to fix https://bugs.dolphin-emu.org/issues/12717 but this ended up not being the issue (instead it seems like files just weren't recompiled when imgui was updated due to MSVC weirdness). Still, using brackets instead of quotes is preferable as this is a library include.
The reload stub is at a fixed address (0x80001800) so its hook flag
should be HookFlag::Fixed.
Otherwise the hook is installed by HLE::PatchFixedFunctions but
immediately removed by HLE::PatchFunctions (which is called by
HLE::Reload right after PatchFixedFunctions).
Should fix https://bugs.dolphin-emu.org/issues/12716
This makes Android ask the user whether they want to delete user
data when uninstalling the app instead of always deleting user data,
which is pretty great now that we're forced to use scoped storage.
It only works on Android 10 and up, though.
This also may eventually allow loading patches from sources other than the 1:1 expected file structure host file system, such as memory or an archive file.
When I made 9c8bb24, I assumed it was completely impossible for a
non-preloaded app to access the entirety of the Android/data/ folder
on Android 11. This turned out to be false. While you can't access
the directory without using SAF (even if you have the Manage All
Files permission), and the user can't navigate to the folder using
the SAF folder picker, what you can do is pass the Android/data/
folder as an EXTRA_INITIAL_URI to the SAF folder picker. If the
user then presses "use this folder" without navigating out of the
folder, the app will be able to access the folder using SAF.
So what does that mean for Dolphin? It means scoped storage is a
little less bad than I feared, and I have a string to adjust.
While trying to work on adding audiodump support for CLI, I was alerted that it was important to first try moving the DSP configs to the new config before continuing, as that makes it substantially easier to write clean code to add such a feature.
This commit aims to allow for Dolphin to only rely on the new config for DSP-related settings.
Frame Advance Speed hotkeys were swapped. This likely occurred because speed and delay are inverses (i.e. a speed increase should DECREASE the delay and vice versa).
This replaces the MAX_LOGLEVEL define with a constexpr variable
in order to fix self-comparison warnings in the logging macros
when compiling with Clang. (Without this change, the log level check
in the logging macros is expanded into something like this:
`if (LINFO <= LINFO)`, which triggers a tautological compare warning.)
GCC complains about float_emit being null when inlining
ByteswapAfterLoad into MMIOLoadToReg. ByteswapAfterLoad
does dereference float_emit, but only when passing FLAG_FLOAT,
which MMIOLoadToReg has an assert for and does not support.
Also cleaning up some unnecessarily specified namespaces while
I'm at it.
The compiler was loudly announcing each and every branch Tev was not checking in
a switch statement, but Tev has learned it's lesson and will produce that
warning no more.
Reusing the slowmem handlers of existing blocks meshes badly
with reusing the empty space left when destroying blocks.
I don't think reusing slowmem handlers was much of a gain anyway.
This is done entirely through interpreter fallbacks. It would
probably be possible to implement this using host exception
handlers instead, but I think it would be a lot of complexity
for a rarely used feature, so let's not do it for now.
For performance reasons, there are two settings for this feature:
One setting which does enables just what True Crime: New York City
needs and one setting which enables it all. The latter makes
almost all float instructions fall back to the interpreter.
Instead of having a single GUI checkbox for "Always Hide Mouse Cursor",
I have instead opted to use radio buttons so the user can swap between
different states of mouse visibility. "Movement" is the default
behavior, "Never" will hide the mouse cursor the entire time the game is
running, and "Always" will keep the mouse cursor always visible.
Previously the unhide of movement mouse_timer reset occurred within case MouseButtonPress.
Additionally, there was a redundant expression in the if statement for cursor locking.
Now works with games that deliberately avoid invalidating TMEM because
they know textures are too large to fit:
* Sonic Riders
* Metal Arms: Glitch in the System
* Godzilla: Destroy All Monsters Melee
* NHL Slapshot
* Tak and the Power of Juju
* Night at the Museum: Battle of the Smithsonian
* 428: Fūsa Sareta Shibuya de
There are two reasons for this.
1. Using Dolphin's logging system lets the user decide whether
the printout should go to the terminal, the GUI, or a file.
fmt::print always prints to stdout... unless you're on Android, in
which case it does nothing at all, because Android disables stdout.
2. The Windows version of Dolphin crashes when you use fmt::print.
Yes, really. The crash happens because a call to std::fprint in
fmt::v7::detail::fwrite_fully returns that less characters were
written than requested, which fmt handles by throwing an exception.
(As always, Dolphin does not use exception handling.)
I'm not sure why std::fprint is doing this, but since switching
away from using fmt::print is a good idea due to the previous point
anyway, I'd say it's best to just switch.
Previously, if you have "Hotkeys Require Window Focus" disabled, you could repeatedly use the "Open" hotkey, for example, to stack File Open windows over top of each other over and over.
This commit allows the hotkey manager to disable/enable on QFileDialog creation and destruction.
Currently the logic for addressing the individual TexUnits is splattered all
across dolphin's codebase, this commit attempts to consolidate it all into a
single place and formalise it using our new TexUnitAddress struct.
MappingWindow is modal, yet the user can use hotkeys while the window is active. I believe hotkeys should not be recognized while this window is active.
This string is extremely likely to be mistranslated without the
proper context. Actually, it's probably impossible to translate
this string in a good way to some languages, but I'm not sure how
to solve that. Let's at least add an i18 comment for now.
PR #10066 added functionality to call std::abort when a panic alert occurs; however, that PR only implemented it for MsgAlert and not MsgAlertFmtImpl, meaning that the functionality was not used with PanicAlertFmt (only PanicAlert, which is not used frequently).
Yes, that's right! It's time to add even more NKit warnings,
because users still don't understand what NKit is or how it works!
More specifically, some users seem to be under the impression that
converting an NKit file to for instance RVZ using Dolphin's convert
feature will result in a normal RVZ file, when it in fact results in
an NKit RVZ file (since NKit is not a container format in the sense
that GCZ/WIA/RVZ/WBFS/CISO is, but rather a kind of trimmed ISO).
I can hardly blame users for not knowing this, because it's not
intuitive unless you know the technical details of how NKit works.
Previously, s_temp_input was being used for BOTH the savestate's and the movie's input printout in the panic alert.
This commit simply performs memcpy from the correct vector for the movInput printout.
