The STL has everything we need nowadays.
I have tried to not alter any behavior or semantics with this
change wherever possible. In particular, WriteLow and WriteHigh
in CommandProcessor retain the ability to accidentally undo
another thread's write to the upper half or lower half
respectively. If that should be fixed, it should be done in a
separate commit for clarity. One thing did change: The places
where we were using += on a volatile variable (not an atomic
operation) are now using fetch_add (actually an atomic operation).

NumericSettings support a max, so let's use it.
It might not do much now, but the max and min values will be used to give visual feeback

The control expression editor allows line breaks, but the serialization was
losing anything after the first line break (/r /n).
Instead of opting to encode them and decode them on serialization

I opted to replace them with a space.

Previously we set the texture coordinate to zero, now we set
the texture coordinate *index* to zero. This fixes the ripple
effect of the Mario painting in Luigi's Mansion.
This change should have no behavioral differences itself, but allows for changing the behavior of out of bounds tex coord indices more easily in the next commit. Without this change, returning tex0 for out of bounds cases and then applying the fixed-point logic would use the wrong tex dimension info (tex0 with I_TEXDIMS[1] or such), which is inaccurate.

Since the description updating is tied to the selection changing on the detail list, and the detail list is recreated on each object change, behavior was somewhat broken. Clearing the list changed the current row to zero, but nothing else (particularly m_object_data_offsets) had been updated, so the description was not necessarily correct (this is easier to observe now since the vertex data is at the end, so it's easier to get different lengths of register updates). Furthermore, subsequent clears did not update the current row since there was no visible selection, so it only changed the description once. The current row is now always set to zero, which forces an update (and also scrolls the list back to the top). The presence of FRAME_ROLE and OBJECT_ROLE are also checked so that the description is cleared if no object is selected.
- Only one search result is generated per command/line, even if there are multiple matches in that line.
- Pressing enter on the edit field begins a search, just like clicking the begin button.
- The next and previous buttons are disabled until a search is begun.
- The search results are cleared when changing objects or frames.
- The previous button once again works (a regression from the previous commit), and the register updates and graphics data for the correct object are searched.
- currentRow() never returns -1, so checking that is unnecessary (and misleading).
- The 'Invalid search parameters (no object selected)' previously never showed up before because FRAME_ROLE is present if and only if OBJECT_ROLE is present.
This way, it can be focused with the render window behind it, instead of having the main window show up and cover the render window. This is useful for adjusting the object range, among other things.
If the number of objects varied, this would result in either missing objects on some frames, or too many objects on some frames; the latter case could cause crashes. Since it used the current frame to get the count, if the FIFO is started before the FIFO analyzer is opened, then the current frame is effectively random, making it hard to reproduce consistently.
This issue has existed since the FIFO analyzer was implemented for Qt.
The 'zero frames in the range' check can be removed because now there is always at least 1 frame; of course that might be the same frame over and over again, but that's still useful for e.g. Free Look (and the 1 frame repeating effect already occurred when frame count was exclusive).
A single object can be selected instead of 2 (it was already inclusive internally), and the maximum value is the highest number of objects in any frame (minus 1) to reduce jank when multiple frames are being played back.
Now that this is only called when playback actually starts (and not on unpausing), this change makes the experience a bit better (no more missing objects from not having reset the from object after changing FIFOs).
It is no longer relevant for the current set of loaders after 7030542546. If it becomes relevant again, a static function named IsUsable or IsCompatibleWithCurrentMachine or something would be a better approach.
In 5a1a642, I explicitly set android:debuggable="true" for Dolphin.
(By default, it's set for debug builds but not release builds.)
The reason I made the change is because debuggable must be set to
true in order to allow adb backup to be used with apps which target
Android 12. We have no reason to want to stop users from debugging
Dolphin and certainly no reason to stop users from using adb backup
(especially not after forced storage is going to force us to store
the User folder in app-specific external storage!), but,
it turns out that setting debuggable to true is forbidden by
Google Play "for security reasons". Go figure. The beta build
which was tagged earlier today was rejected because of this.
By taking advantage of three-operand IMUL, we can eliminate a MOV
instruction. This is a small code size win. However, due to IMUL sign
extending the immediate value to 64 bits, we can only apply this when
the magic number's most significant bit is zero.
To ensure this can actually happen, we also minimize the magic number by
checking for trailing zeroes.

This isn't entirely necessary, as they are interpreted as barewords expressions,

Avoids the need to copy the *.mo files manually *and* more importantly

Update references was failing to update the references, causing input to stay nullptr and crashing.
I fixed the case that triggered that, though also added checks against nullptrs for safety.

I think the AArch64 JIT has come far enough that it doesn't have to
be called experimental anymore.
I'm also labeling the x86-64 JIT as x86-64 for consistence with the
AArch64 JIT. This will especially be helpful if we start supporting
AArch64 on macOS, as AArch64 macOS can run both the x86-64 JIT and
the AArch64 JIT depending on whether you enable Rosetta 2.
I haven't observed this breaking any game, but it didn't match
the behavior of the interpreter as far as I could tell from
reading the code, in that denormals weren't being flushed.
If we can prove that FCVT will provide a correct conversion,
we can use FCVT. This makes the common case a bit faster
and the less likely cases (unfortunately including zero,
which FCVT actually can convert correctly) a bit slower.
Preparation for following commits.
This commit intentionally doesn't touch paired stores,
since paired stores are supposed to flush to zero.
(Consistent with Jit64.)
This simplifies some of the following commits. It does require
an extra register, but hey, we have 32 of them.
Something I think would be nice to add to the register cache
in the future is the ability to keep both the single and double
version of a guest register in two different host registers
when that is useful. That way, the extra register we write to
here can be read by a later instruction, saving us from
having to perform the same conversion again.
Fixes https://bugs.dolphin-emu.org/issues/12388. Might also fix
other games that have problems with float/paired instructions
in JitArm64, but I haven't tested any.
-They might have never drawn if DrawMessages wasn't called before they actually expired
-Their fade was wrong if the duration of the message was less than the fade time
This makes them much more useful for debugging, I know there might be other means
of debugging like logs and imgui, but this was the simplest so that's what I used.
If you want to print the same message every frame, but with a slightly different value
to see the changes, it now work.
To compensate for the fact that they are now always rendered once,
so on start up a lot of old messages (printed while the emulation was off) could show up,
I've added a "drop" time, which means if a msg isn't rendered for the first
time within that time, it will be dropped and never rendered.
When the interpreter writes to a discarded register, its type
must be changed so that it is no longer considered discarded.
Fixes a 62ce1c7 regression.
We normally check for division by zero to know if we should set the
destination register to zero with a XOR. However, when the divisor and
destination registers are the same the explicit zeroing can be omitted.
In addition, some of the surrounding branching can be simplified as
well.

Repeated erase() + iteration on a std::multimap is extremely slow.
Slow enough that it causes a 7 second long stutter during some
transitions in F-Zero X (a N64 VC game that triggers many, many icache
invalidations).
And slow enough that JitBaseBlockCache::DestroyBlock shows up on a
flame graph as taking >50% of total CPU time on the CPU-GPU thread:
https://i.imgur.com/vvqiFL6.png
This commit optimises those block link queries by replacing the
std::multimap (which is typically implemented with red-black trees)
with hash tables.

Coupled with the commit that makes Dolphin not clobber 0x1800-0x3000
when using MIOS, this fixes Wind Waker and other MIOS-patched games
when they are launched from the System Menu.
MIOS puts patch data in low MEM1 (0x1800-0x3000) for its own use.
Overwriting data in this range can cause the IPL to crash when
launching games that get patched by MIOS.
See https://bugs.dolphin-emu.org/issues/11952 for more info.
Not applying the Gecko HLE patches means that Gecko codes will not work
under MIOS, but this is better than the alternative of having specific
games crash.
This particular range is kind of bizarre, and would only interpret
interleave mode 2 as a valid mode, while rejecting interleave mode 1 and
the extension byte mode.
As far as I know, based off the information on Wiibrew, we should be
considering all three values within this range as valid.
texture serialization and deserialization used to involve many memory
allocations and deallocations, along with many copies to and from
those allocations. avoid those by reserving a memory region inside the
output and writing there directly, skipping the allocation and copy to
an intermediate buffer entirely.
We don't actually need to do this until we bump targetSdkVersion
to Android 12 (which we can't do yet since we're not compatible

This adds a CMake option (DOLPHIN_DEFAULT_UPDATE_TRACK) to allow
configuring SCM_UPDATE_TRACK_STR. This is needed to enable auto-updates
in Windows CMake builds by default.
fmt/format.h is included in the PCH, so we need to make sure fmt is
actually in the include path.
Not sure how Visual Studio + CMake manages to build without this.
This adds a function to get the emulated or real Bluetooth device for
an active emulation instance. This lets us deduplicate all the
`ios->GetDeviceByName("/dev/usb/oh1/57e/305")` calls that are currently
scattered in the codebase and ensures Bluetooth passthrough is being
handled correctly.
This also fixes the broken check in WiimoteCommon::UpdateSource.
There was a confusion between "emulated Bluetooth" (as opposed to
"real Bluetooth" aka Bluetooth passthrough) and "emulated Wiimote".

Specifically, 'Scooby-Doo! Mystery Mayhem', 'Scooby-Doo! Unmasked', 'Ed, Edd n Eddy: The Mis-Edventures', and the Wii version of 'Happy Feet'.
The JIT cache causes problems with emulated icache invalidation in these games, resulting in areas failing to load.
This avoids some warnings, which were originally fixed by ignoring loads with a value of zero (see 636bedb207 / #3242).
Note that FifoCI will report some changes, but only on the first frame; these seem to be timing related as they don't happen if a different write is used to replace skipped ones.
They appear to relate to perf queries, and combining them with truely unknown commands would probably hide useful information. Furthermore, 0x20 is issued by every title, so without this every title would be recorded as using an unknown command, which is very unhelpful.
The swaps are confusing and don't accomplish much.
It was originally written like this:
u32 pte = bswap(*(u32*)&base_mem[pteg_addr]);
then bswap was changed to Common::swap32, and then the array access
was replaced with Memory::Read_U32, leading to the useless swaps.
While 6xx_pem.pdf §7.6.1.1 mentions that the number of trailing
zeros in HTABORG must be equal to the number of trailing ones
in the mask (i.e. HTABORG must be properly aligned), this is actually
not a hard requirement. Real hardware will just OR the base address
anyway. Ignoring SDR changes would lead to incorrect emulation.
Logging a warning instead of dropping the SDR update silently is a
saner behaviour.
debaf63fe8 moved the "Sonic epsilon hack"
to vertex shaders. However, it was only done for targets with depth
clamping. If this is not available, for example the target is OpenGL ES,
the Sonic problem appears (https://bugs.dolphin-emu.org/issues/11897).
A version of the "Sonic epsilon hack" is added for targets without
depth clamping.
This changes FileSystemProxy::Open to return a file descriptor wrapper
that will ensure the FD is closed when it goes out of scope.
By using such a wrapper we make it more difficult to forget to close
file descriptors.
This fixes a leak in ReadBootContent. I should have added such a class
from the beginning... In practice, I don't think this would have caused
any obvious issue because ReadBootContent is only called after an IOS
relaunch -- which clears all FDs -- and most titles do not get close
to the FD limit.
JitArm64::DoJit contains a check where it prints a warning and tries
to pause emulation if instructed to compile code at address 0. I'm
assuming this was done in order to provide a nicer error behavior
in cases where PC was accidentally set to null. Unfortunately, it
has started causing us problems recently, as 688bd61 writes and runs
some code at address 0 to simulate the PPC being held in reset.
What makes this worse is that calling Core::SetState from the CPU
thread is actually not allowed and will cause a deadlock instead of
the intended behavior. I don't believe there is anything on a real
console that would stop you from executing code at address 0 (as
long as the MMU has been set up to allow it), and Jit64::DoJit
doesn't contain any check like this, so let's remove the check.
Many Android users want to disable SyncOnSkipIdle as a performance
hack, to the point where it's often suggested as something to
paste into Dolphin.ini (if not to use a fork). If adding it as
a setting in the GUI gives us an opportunity to explain what the
setting actually does and stops people from pasting stuff they
don't understand into INI files, I think it can be worth adding
despite how it can make games unstable. It not being in the GUI
doesn't seem to be stopping people from disabling it anyway.
The added setting in the GUI is a three-way setting called
"Synchronize GPU Thread" with the following alternatives:
"Never": SyncGPU = False, SyncOnIdleSkip = False
"On Idle Skipping": SyncGPU = False, SyncOnIdleSkip = True
"Always": SyncGPU = True, SyncOnIdleSkip = True
See PR 8203 for background on the game INI deletion prompt.
It's been almost two years since PR 8203 was merged, so you
would think that people are no longer creating game INIs that
contain a copy of every global setting, right? Unfortunately,
MMJ was forked not too long before that and never backported the
change, so right now there's a not insignificant number of people
online posting game INIs full of this garbage for others to use.
One thing that's been missing from the game INI deletion prompt
is a description of what the problem with having tons of extra
lines in a game INI actually is. This change adds that, in the
the hope that it will make people ignore the warning less often.
This option does in fact not enable and disable logging as a whole.
You can get logs through logcat regardless of this setting.
Also taking the opportunity to remove the reference to
the "dolphin-emu" folder name since we will no longer be
using that folder once scoped storage is applied to Dolphin.
This commit adds a new "discarded" state for registers.
Discarding a register is like flushing it, but without
actually writing its value back to memory. We can discard
a register only when it is guaranteed that no instruction
will read from the register before it is next written to.
Discarding reduces the register pressure a little, and can
also let us skip a few flushes on interpreter fallbacks.
The output of instructions like fabsx and ps_sel is store-safe
if and only if the relevant inputs are. The old code was always
marking the output as store-safe if the output was a single,
and never otherwise.
Also, the old code was treating the output of psq_l/psq_lu as
store-safe, which seems incorrect (if dequantization is disabled).
This improves the speed of verifying Wii WIA/RVZ files.
For me, the verification speed for LZMA2-compressed files
has gone from 11-12 MiB/s to 13-14 MiB/s.
One thing VolumeVerifier does to achieve parallelism is to
compute hashes for one chunk of data while reading the next
chunk of data. In master, when reading data from a Wii
partition, each such chunk is 32 KiB. This is normally fine,
but with WIA and RVZ it leads to rather lopsided read times
(without the compute times being lopsided): The first 32 KiB
of each 2 MiB takes a long time to read, and the remaining
part of the 2 MiB can be read nearly instantly. (The WIA/RVZ
code has to read the entire 2 MiB in order to compute hashes
which appear at the beginning of the 2 MiB, and then caches
the result afterwards.) This leads to us at times not doing
much reading and at other times not doing much computation.
To improve this, this change makes us use 2 MiB chunks
instead of 32 KiB chunks when reading from Wii partitions.
(block = 32 KiB, group = 2 MiB)
This can't actually happen in practice due to how WAD files work,
but it's very easy to add support for thanks to the last commit,
so we might as well add support for it.
The performance gains of doing this aren't too important since you
normally wouldn't run into any disc image that has overlapping blocks
(which by extension means overlapping partitions), but this change also
lets us get rid of things like VolumeVerifier's mutex that used to
exist just for the sake of handling overlapping blocks.
Panic alerts in DiscIO can potentially be very annoying since
large amounts of them can pop up when loading the game list
if you have some particularly weird files in your game list.
This was a much bigger problem back in 5.0 with its
"Tried to decrypt data from a non-Wii volume" panic alert, but
I figured I would take it all the way and remove the remaining
panic alerts that can show up when loading the game list.
I have exempted uses of ASSERT/ASSERT_MSG since they indicate
a bug in Dolphin rather than a malformed file.
If we know at compile time that the PPC carry flag definitely
has a certain value, we can bake that value into the emitted code
and skip having to read from PPCState.
GameFileCacheService.startRescan (in MainPresenter.onResume)
does nothing if called before GameFileCacheService.startLoad.
Fixes a 3f71c36 regression where already added games would not
show up after app launch under specific circumstances.
Unfortunately the loading indicator still doesn't show up
during a rescan initiated by app launch, but that would
be more annoying to fix, so I will leave it for now.
When a save state is loaded, the IOS device serving bluetooth
is cast as BluetoothEmuDevice. If, however, a real Wiimote
with BT passthrough is used, this caused the game to crash.
Now the proper device class is used.
At a first glance it may look like a part of the code I added to
srawx in efeda3b has a bug when a == s. The code actually happens
to work correctly, but in the interest of making the code easier
to reason about, I'd like to change the way it's implemented. This
change should improve the pipelining a little in the a == s case too.

21c152f added a small hack to DVDInterface to keep WBFS and CISO
files working with Nintendo's "Error #001" anti-piracy check.
Unfortunately I don't think it's possible to support WBFS and
CISO without any kind of hack or heuristic, but what we can do
is replace the 21c152f hack (which applies regardless of file
format) with a hack that only is active when using WBFS or CISO.
This change is similar to 2a5a399, but the disc size is
calculated in a different way.
Add ! before unused variables to 'use' them.
Ubuntu-x64 emits warnings for unused variables because gcc decides
it should ignore the void cast around them. See thread for discussion:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66425
Loop index int i was being compared against GetControllerCount() which
returned a size_t. This was the only place GetControllerCount() was
called from so the change of return type doesn't disturb anything else.
Changing the loop index to size_t wouldn't work as well since it's
passed into GetController(), which takes an int and is called from many
places, so it would need a cast anyway on an already busy line.

Fairly common with constant dividend of zero. Non-zero values occur

Whether the custom RTC setting is enabled shouldn't in itself
affect determinism (as long as the actual RTC value is properly
synced). Alters the logic added in 4b2906c.
I'm not entirely certain that this is correct, but the current
code doesn't really make sense to me... If we need to force the
RTC bias to 0 when custom RTC is enabled, why don't we need to
do it when custom RTC is disabled? The code for getting the
host system's current time doesn't contain any special handling
for the guest's RTC bias as far as I can tell.
The loop in WIARVZFileReader::Chunk::Read could terminate
prematurely if the size argument was smaller than the size
of an exception list which had only been partially loaded.
Fixes issue 11393.
The problem is that left and top make no sense for a width by height array; they only make sense in a larger array where from which a smaller part is extracted. Thus, the overall size of the array is provided to CopyRegion in addition to the sub-region. EncodeXFB already handles the extraction, so CopyRegion's only use there is to resize the image (and thus no sub-region is provided).
BPMEM_TEV_COLOR_ENV + 6 (0xC6) was missing due to a typo. BPMEM_BP_MASK (0xFE) does not lend itself well to documentation with the current FIFO analyzer implementation (since it requires remembering the values in BP memory) but still shouldn't be treated as unknown. BPMEM_TX_SETMODE0_4 and BPMEM_TX_SETMODE1_4 (0xA4-0xAB) were missing entirely.
Additional changes:
- For TevStageCombiner's ColorCombiner and AlphaCombiner, op/comparison and scale/compare_mode have been split as there are different meanings and enums if bias is set to compare. (Shift has also been renamed to scale)
- In TexMode0, min_filter has been split into min_mip and min_filter.
- In TexImage1, image_type is now cache_manually_managed.
- The unused bit in GenMode is now exposed.
- LPSize's lineaspect is now named adjust_for_aspect_ratio.
Additionally, VCacheEnhance has been added to UVAT_group1. According to YAGCD, this field is always 1.
TVtxDesc also now has separate low and high fields whose hex values correspond with the proper registers, instead of having one 33-bit value. This change was made in a way that should be backwards-compatible.
We want to save the currently selected platform tab,
but doing so immediately after switching tabs leads to
unnecessarily much file I/O (on the main thread, no less).
This change makes us defer the saving until later.
In master, the game scanning process looks like this:
1. Scan for games
2. Scan for additional metadata (icon.png and meta.xml)
3. Save the cache if needed
4. Update the game list with the results
This change makes the game scanning process look like this:

Updating the game list as soon as possible means the user
has to wait less before their games show up. The new behavior
matches what DolphinWX did before it was removed. (DolphinQt
has an even fancier approach where games get added one by one.)
The PPC is supposed to be held in reset when another version of IOS is
in the process of being launched for a PPC title launch.
Probably doesn't matter in practice, though the inaccuracy was
definitely observable from the PPC.
We should only try to load a symbol map for the new title *after* it
has been loaded into memory, not before. Likewise for applying HLE
patches and loading new custom textures.
In practice, loading/repatching too early was only a problem for
titles that are launched via ES_Launch. This commit fixes that.
The extra IPC ack is triggered by a syscall that is invoked in ES's
main function; the syscall literally just sets Y2, IX1 and IX2 in
HW_IPC_ARMCTRL -- there is no complicated ack queue or anything.
Low MEM1 is cleared by IOS before all the other constants are written.
This will overwrite the Gecko code handler but it should be fine
because HLE::Reload (which will set up the code handler hook again)
will be called after a title change is detected.
The Host constructor sets a callback on a lambda that in turn calls
Host_UpdateDisasmDialog. Since that function is not a member function
capturing this is unnecessary.
Fixes -Wunused-lambda-capture warning on freebsd-x64.
When reading a reply from a message sent to the data socket there is
the possibility that the other side gets sent multiple messages
before replying to any of them, which can lead to multiple replies
sent in a row. Though this only happens when things time out, it's
quite possible for these timeouts to happen or build up over time,
especially when initiating the connection.
This change makes sure to flush any pending bytes that have not been
read yet out of the socket after a successful POLL reply is received,
since that is the most common time when backups occur, and as well as
using the exact number of bytes in an expected reply, to ensure
the received data and the message it's replying to do not get out of
sync.
The result of calls to PPCSTATE_OFF_PS0/1 were being cast to u32 and
passed to functions expecting s32 parameters. This changes the casts
to s32 instead.
One location was missing a cast and generated a warning with VS which
is now fixed.
Added `ToggleBreakPoint` to both interface BreakPoints/MemChecks. this would allow us to toggle the state of the breakpoint.
Also the TMemCheck::is_ranged is not longer serialized to string, since can be deduce by comparing the TMemCheck::start_address and TMemCheck::end_address
DualShock UDP Client is the only place in the code that assumed OnConfigChanged()
is called at least once on startup or it won't load up the setting, so I took care of that
The main reason why I'm adding this isn't actually to allow
users to swipe down to refresh, it's to add a loading indicator.
Considering that the Storage Access Framework can be slow for
folders with many items (many subfolders?), not showing a
loading indicator might give users the impression that adding
a folder resulted in nothing happening even though Dolphin is
scanning for games in the background. But I suppose letting
users swipe down to refresh is a nice bonus with the change.
This was caused, because we were saving the `break_on_hit` flag with the letter `p`. Then while loading the breakpoints, we read the flag with the letter `b`, resulting in the `break_on_hit` flag being always false
Filesystem accesses aren't magically faster when they are done by ES,
so this commit changes our content wrapper IPC commands to take FS
access times and read operations into account.
This should make content read timings a lot more accurate and closer
to console. Note that the accuracy of the timings are limited to the
accuracy of the emulated FS timings, and currently performance
differences between IOS9-IOS28 and newer IOS versions are not emulated.
Part 1 of fixing https://bugs.dolphin-emu.org/issues/11346
(part 2 will involve emulating those differences)
This makes it more convenient to emulate timings for IPC commands that
perform internal IOS <-> IOS IPC, for example ES relying on FS
for filesystem access.
According to hwtests, older versions of IOS are slower at performing
various filesystem operations:

A quick glance at IOS9 reveals that older versions of IOS have a
simplistic implementation of memcpy that does not optimize large copies
by copying 16 bytes or 32 bytes per chunk, which makes cached reads
and writes noticeably slower -- the difference was significant enough
that the OoT speedrunning community noticed that IOS9 (the IOS that
is used for the OoT VC title) was slower.
