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.
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
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.

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.
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.
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 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.
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.
Previously, the file dialog window was ambiguous between saving or loading a .dtm. This commit simply gives a bit more context to differentiate the two windows.
Previously, when playing back a movie, you could not see the total frame count of a movie, only the total number of input polls.
This change simply shows the total frame count on movie playback.
Note that this change also results in the framecount and framecount total ALWAYS being displayed if show_movie_window is true, regardless of whether or not m_ShowFrameCount is true. I believe this is fine, as TASers are much more likely to reference the framecount than the input poll count.
Previously, only the number of total input polls would be shown in the window title when playing back a movie. This simply adds the VI / frame count total as well, which is a much more relevant number to look at while TASing.
