Renames some variables to avoid shadowing warnings on gcc.
Also gets rid of a FilereaderState struct, since one is already defined
in the declaration of the AchievementManager class.
These aren't necessarily cheap to copy, since a control qualifier will
have around 3 std::strings inside of it, so passing by value can churn
allocations a little bit.
std::function is internally allowed to allocate, and these functions
aren't being stored anywhere (only called), so we can freely get rid
of some minor overhead here by passing by reference.
This change also creates aliases for the functions, so that there isn't
a lot of visual noise when reading the function signatures.
We don't need to enforce the use of std::string instances with
AddSetting(). We can accept views and only construct one string,
rather than three temporaries.
Internal details: The large region is split into individual same-sized blocks of memory. On creation, we allocate a single block of memory that will always remain zero, and map that into the entire memory region. Then, the first time any of these blocks is written to, we swap the mapped zero block out with a newly allocated block of memory. On clear, we swap back to the zero block and deallocate the data blocks. That way we only actually allocate one zero block as well as a handful of real data blocks where the JitCache actually writes to.
The active challenges, aka the primed achievements, are displayed on screen as a series of icons in the bottom right corner of the screen via OnScreenUI.
Emulation state changed signals also update the wiimote connection. The signal here is only needed for wiimote connects/disconnects.
Can fix erroneous debugger behavior during booting, as dolphin will sometimes incorrectly report the state as paused, which leads the debugger widgets to run when they shouldn't.
When an achievement is "primed", a challenge is active, for example completing a portion of the game in under a time limit or without taking damage or using certain items. This is stored in a map in the Achievement Manager (and removed when the achievement is unprimed) so a later commit can display it on screen.
The Disabled state sits between Game Closed and completely Shutdown - stronger than the former, as it refuses to let a game be opened again until AchievementManager is restored (which only happens upon a fresh core boot) but it isn't completely shut down and will still allow the player to be logged in and access the achievement settings and their (global) achievement header.
This change splits LoadGameAsync into three methods: two HashGame methods to accept either a string filepath or a volume, and a common LoadGameSync that both HashGames call to actually process the code. In the process, some minor cleanup, and the hash resolution now takes place on the work queue asynchronously.
Normally we only flush registers right at the end of each PPC
instruction. However, for PPC instructions that use a lot of registers
one at a time, it's beneficial to do this flushing work in the middle
of the instruction instead, reducing the risk of register starvation
and improving pipelining.
This should have been done when rebasing 6cc4f593e5 after the merge of
3a00ff625e. There are no correctness implications as far as I know,
only very minor performance implications.
This worked correctly on the JIT vertex loaders, and for the equivalent case with texture coordinates. I'm not aware of any games this affects (but libogc does mention a semi-related scenario at 6bc0317c7d/gc/ogc/gx.h (L1855-L1857).)
Jimmie Johnson's Anything with an Engine is known to use texture coordinate 7 (and only texture coordinate 7) in some cases. There are a lot of possible edge-cases, so this test brute-forces all combinations with coordinates 0, 1, and 2.
This adds the actual switch to turn on Hardcore Mode to the settings tab of the Achievements dialog. It is accompanied by a large tooltip warning explaining what it does and when it can be enabled.
The switch is only enabled to be turned on when no game is running, so that games are started in hardcore mode and can only be loaded via the console's memory card, as in the original hardware. Hardcore may be turned off while a game is running, but cannot be turned back on until the game is disabled.
The toggle trigger for hardcore mode also automatically disables the settings that are not allowed during hardcore mode.
Finally, the original flag in AchievementSettingsWidget to set whether things are enabled in hardcore mode (primarily Leaderboards) is replaced with the actual Hardcore Mode setting.
Play Input Recording would potentially unlock achievements without any player input and needs to be disabled. If a recording is already playing, hardcore mode cannot be enabled.
The player getting a better view of their surroundings than the game would normally allow could possibly give the player an advantage over the original hardware, so Freelook is disabled in hardcore mode. To do this, I disable the config flag for Freelook when it is accessed, to make sure that it is disabled whether it was enabled before or after hardcore mode was enabled.
Memory patches would be an easy way to manipulate the memory needed to calculate achievement logic, so they must be disabled. Riivolution patches that do not affect memory are allowed, as they will be hashed with the game file.
Debug Mode gives players direct read and write access to memory, which could be used to completely manipulate RetroAchievements logic and therefore is not allowed in hardcore mode.
Slowing down the emulator would artificially improve reaction times and is therefore disallowed in hardcore mode. Speeds faster than 1x are allowed, but any speed below 1x is scaled back up to 1x.
Frame advancing is easily exploitable for slowing down a game and artificially improving reaction times and is not allowed in RetroAchievements hardcore mode.
While saving states is allowed (especially for the purpose of debugging), RetroAchievements does not allow loading saved states when hardcore mode is on.
This widget will be used in several places to notify the player that a feature has been disabled because hardcore mode is on. It includes a button to open the Achievement Settings so that Hardcore Mode may be turned off. Also included is the framework required to open AchievementsWindow specifically on the Settings tab.
Hardcore Mode is a RetroAchievements feature for enabling as close to original hardware as possible, to keep a fair, challenging, and competitive playing field for achievements (which get tallied differently and emphasized more in hardcore) and leaderboards (where it is mandatory) at the cost of several common emulator features that provide advantages, such as state loading and slower emulation speeds.
This commit just adds the flag to the AchievementSettings, with more to come.
Dolphin would crash when running with a fastmem arena but without
fastmem. This regression was caused by merging 9192128c50 without
adapting it after the merge of 0606433404.
This has the same effect in the end, but in my opinion, doing it this
way makes it more clear for the reader why we can read from ppcState at
JIT time, something that makes no sense for everything else in ppcState.
By making the JIT cache check if the current state of MMCR0 and MMRC1
matches the state they had at the time the JIT block was compiled, we
solve a correctness issue (marked in a comment as a speed hack).
Not known to affect any games.
This must have broken in a rebase of one of my recently merged PRs.
Dolphin still worked correctly with this bug, for two reasons:
1. Most AArch64 users are not on Windows, and therefore normally do have
the entry points map.
2. When the bug was triggered, Dolphin would fall back to the slower
path rather than crashing.
Instead of shifting left by 1, we can first shift right by 2 and then
left by 3. This is both faster and smaller, because we get the right
shift for free with the masking and the left shift for free with the
address calculation. It also happens to match the pseudocode more
closely, which is always nice for readability.
This slightly improves instruction-level parallelism in Jit64's slow
dispatcher by shifting the PC left instead of the MSR.
In the past, this also enabled an optimization in JitArm64's fast path
where we could use LDP to load normalEntry and msrBits in one
instruction, but this was superseded by fd9c970.
Just to make the code easier to understand at a glance. I especially
found it a bit annoying to reason about whether callee-saved registers
like W28 were being used because we needed a callee-saved register or
just for no reason in particular.
X8 and up is what compilers normally use when they're not register
starved.
AArch64's handling of NaNs in arithmetic instructions matches PowerPC's
as long as no more than one of the operands is NaN. If we know that all
inputs except the last input are non-NaN, we can therefore skip checking
the last input. This is an optimization that in principle only works for
non-SIMD operations, but ps_sumX effectively is non-SIMD as far as the
arithmetic part of it is concerned, so we can use it there too.
FL_EVIL is only used for blocking instructions from being reordered.
There are three types of instructions which have FL_EVIL set:
1. CR operations. The previous commits improved our CR analysis
and removed FL_EVIL from these instructions.
2. Load/store operations. These are always blocked from reordering
due to always having canCauseException set.
3. isync. I don't know if we actually need to prevent reordering
around this one, since as far as I know we only do reorderings
that are guaranteed to not change the behavior of the program.
But just in case, I've renamed FL_EVIL to FL_NO_REORDER instead of
removing it entirely, so that it can be used for this instruction.
Other than the CR instructions, which we now analyze properly,
all the covered instructions are not integer operations and also
have either FL_ENDBLOCK or FL_EVIL set, so there are two other
checks in CanSwapAdjacentOps that will reject them.
This brings the analysis done for condition registers
more in line with the analysis done for GPRs and FPRs.
This gets rid of the old wantsCR member, which wasn't actually
used anyway. In case someone wants it again in the future, they
can compute the bitwise inverse of crDiscardable.
Instead of materializing the quiet bit in a register and ORing the NaN
with it, we can perform an arithmetic operation on the NaN. This is a
cycle or two slower on some CPUs in cases where generating the quiet bit
pipelined well, but this is farcode that rarely runs, so instruction
fetch latency is the bigger concern. And for non-SIMD cases, we also
save a register.
By using MOVI2R+MOVI2R+CSEL in the zero case instead of doing bitwise
operations on the output of the other MOVI2R+MOVI2R+CSEL, we avoid using
BFI, an instruction that takes two cycles on most CPUs. The instruction
count is the same and the pipelining should be at least equally good.
This is a little trick I came up with that lets us restructure our float
classification code so we can exit earlier when the float is normal,
which is the case more often than not.
First we shift left by 1 to get rid of the sign bit, and then we count
the number of leading sign bits. If the result is less than 10 (for
doubles) or 7 (for floats), the float is normal. This is because, if the
float isn't normal, the exponent is either all zeroes or all ones.
Not sure if this was causing correctness issues – it depends on whether
the HLE code was actually reading the discarded registers – but it was
at least causing annoying assert messages in one piece of homebrew.
Nowadays, basically everything except for controller config is handled
by the new config system. Instead of enumerating the systems that are,
let's enumerate the systems that aren't.
I've intentionally not included Config::System::Session in the new list.
While it isn't intended to be saved, it is a setting that's fully
handled by the new config system. See
https://github.com/dolphin-emu/dolphin/pull/9804#discussion_r648949686.
This is used as a base pointer inside CustomPipelineAction, so this
should probably really have a virtual destructor to ensure derived
objects are torn down properly.
The point of farcode is to provide a separate location for code that
rarely runs, so that it doesn't pollute the icache. Taking a conditional
branch is something that happens very often, so the code for that
shouldn't be in farcode.
Bug: https://bugs.dolphin-emu.org/issues/13404
On macOS 13.6 / Intel HD 5000, Dolphin crashes with this message:
> -[MTLIGAccelDevice setShouldMaximizeConcurrentCompilation:]: unrecognized selector
This should be available on all macOS 13.3+ systems – but when using OCLP drivers,
some devices use an older version of Metal.framework, which doesn't expose the selector.
This concerns Intel Ivy Bridge, Haswell and Nvidia Kepler when using OCLP on macOS 13.3
or newer.
(See
34676702f4/docs/PATCHEXPLAIN.md (L354C1-L354C83))
As the behavior is an optional optimization anyway, perform a dynamic
detection to avoid crashing if the feature is not available.
Some state changes are meant to be near instantanoues, before switching to something else. By reporting ithe instant switch, the UI will flicker between states (pause/play button) and the debugger will unnecessarily update. Skipping the callback avoids these issues.
This was implemented to prevent UI flickering due to the state rapidly switching between pause/play. Recently, it has been causing issues with debugger windows, which update during frame advance.
This way, the number of loop iterations is equal to the number of set
bits in the bitset rather than the number of bits in the bitset,
which is a good improvement because usually very few bits are set.
This caused us to update the indirect texture information in shaders more often than we needed to, which probably doesn't matter in practice since it's only used in ubershaders and copyyscale and stride are generally only updated before EFB/XFB copies, which generally will have other changes afterwards.
As far as I can tell, it has nothing to do with the mipmap/half_scale functionality, but does change based on the width of the destination texture (and the destination texture is half the width if half_scale is set). The comment that was there (which dates back to the initial megacommit) seems to not have accounted for the width aspect; it was first used as an actual stride in bbbe898839 (the first commit that used it at all).
The move assignment operator for a class is implicitly deleted when the
class has a non-static reference data member, which is true of
WiiSocket's m_socket_manager member.
Explicitly declaring the operator as default generates a
-Wdefaulted-function-deleted warning on Clang.
Delete the move constructor as well for consistency.
Fix -WSwitch warning about unhandled enum value SDL_NUM_LOG_PRIORITIES.
log_level is initialized to LNOTICE right before the switch statement so
this doesn't cause any behavior changes.
Use RunOnCPUThread instead of RunAsCPUThread in BeginRecordingInput.
Most OpenGL functions require an OpenGL context to have been created on
that thread before calling the function; when that isn't the case they
return invalid results which can cause crashes when passed into other
functions.
Dolphin creates the OpenGL context in the EmuThread which then becomes
either the CPU-GPU thread or the Video thread for single and dual core
respectively. OpenGL functions must therefore be called from that
thread.
Movie::BeginRecordingInput is called from the Host thread and runs a
block of code which ultimately creates a savestate, which in turn embeds
the framebuffer which requires calling various OpenGL functions.
In single core the use of RunAsCPUThread leads to this all happening on
the Host thread, eventually leading to invalid OpenGL calls and a crash.
In Dual core the crash is avoided because VideoBackendBase::DoState uses
the AsyncRequests::DO_SAVE_STATE event which causes VideoCommon_DoState
and its subsequent OpenGL calls to safely run on the Video thread.
This commit uses RunOnCPUThread instead of RunAsCPUThread, which causes
the subsequent code to run on the CPU-GPU thread in single core which
has the valid OpenGL context and so doesn't crash.
This makes it so that if you just want to reload the current style (eg. on program start, or in response to a system event), you don't need to know the name of the currently selected user style. It's also more consistent with the way the 'userstyle/enabled' flag works.
Before dbf5dca, the dirty flag had no meaning for an immediate value,
so we made sure to always set the dirty flag when switching a register
from Immediate to Register. But after dbf5dca, that is no longer the
case. If an immediate is marked as not dirty, we can keep the register
marked as not dirty after materializing the value. This way we skip
having to write it back to ppcState later.
Without this change, non-dirty immediates don't actually get flushed.
This can be a problem if we for instance are flushing all registers in
order to execute an interpreter fallback. If that interpreter fallback
writes to a register that contained a non-dirty immediate, the JIT will
keep using the old value instead of loading the updated value.
This required a change in the denormal path where, instead of
subtracting 11 before shifting left, we shift left immediately and then
shift right by 11. This shouldn't affect performance.
Instead of combining X2 (the exponent) and X3 (the mantissa) using an
ORR instruction, we can read X1, which already contains both.
This requires us to reconstruct X1 in the denormal path, but that's
an acceptable price.
Dolphin's JITs have a minor terminology problem: The term "fastmem" can
refer to either the system of switching between a fast path and a slow
path using backpatching, or to the fast path itself. To hopefully make
things clearer, I'm adding some new terms, defining the old and new
terms as follows:
Fastmem: The system of switching from a fast path to a slow path by
backpatching when an invalid memory access occurs.
Fast access: A code path that accesses guest memory without calling C++
code.
Slow access: A code path that accesses guest memory by calling C++ code.
With this, situations where multiple arguments need to be moved
from multiple registers become easy to handle, and we also get
compile-time checking that the number of arguments is correct.
At the end of each frame automatically update the Current Value for
visible table rows in the selected and visible CheatSearchWidget (if
any). Also update all Current Values in all CheatSearchWidgets when the
State changes to Paused.
Only updating visible table rows serves to minimize the performance cost
of this feature. If the user scrolls to an un-updated cell it will
promptly be updated by either the next VIEndFieldEvent or the State
transitioning to Paused.
If dcache is enabled when the game starts, initializing the fastmem
arena is still useful in case the user changes the dcache setting.
And initializing it doesn't really cost anything.
Preparation for the next commit.
JitArm64 has been conflating these two flags. Most of the stuff that's
been guarded by fastmem_arena checks in fact requires fastmem.
When we have fastmem_arena without fastmem, it would be possible to do
things a bit more efficiently than what this commit does, but it's
non-trivial and therefore I will leave it out of this PR. With this
commit, we effectively have the same behavior as before this PR - plus
the added ability to toggle fastmem with a cache clear.
This is needed so that the checks added in the previous commit will be
reevaluated if the value of m_enable_dcache changes.
JitArm64 was already recompiling its asm routines on cache clear by
necessity. It doesn't have the same setup as Jit64 where the asm
routines are in a separate region, so clearing the JitArm64 cache
results in the asm routines being cleared too.
Some code paths in EmuCodeBlock.cpp that were checking fastmem_arena
should really also be checking m_enable_dcache.
Because JitArm64 centralizes more or less all memory access to the
EmitBackpatchRoutine function and because that function already
contained a check, JitArm64 works fine without the additional checks
added by this commit. Regardless, I added the checks to MMU.cpp instead
of EmuCodeBlock.cpp where applicable so they would be available to
JitArm64. Maybe one day JitArm64 will need them if its code gets
restructured.
The table only needs to be recreated when the displayed addresses might
change. If we're just refreshing the current values then update those
table cells and leave the rest of the table alone.
The code previously did this indirectly via `std::map<double, int>`, the key being the timestamp, which required a questionable workaround for the case where multiple states have the same timestamp. By having a particular combination of timestamps in the on-disk savestates, you could cause this workaround to infinitely loop, locking up Dolphin. This avoids this completely by refactoring the logic and just using `std::vector` instead.
Since ccf92a3e56, recording fifologs multiple times after launching dolphin caused all initial state to not be saved (the initial contents of bpmem, cpmem, etc were all zeroed out). For some games, this was not noticeable, as most registers were set each frame, but for others, this resulted in completely broken fifologs. (Note that recording fifologs also required 05181f6b88 and 9e0755a598 to be cherry-picked due to other, since fixed, regressions.)
This was because previously, `Renderer::CheckFifoRecording` was called every frame, but ccf92a3e56 changed it into a callback (`m_end_of_frame_event`) that was removed when recording ended. Thus, before, `OpcodeDecoder::g_record_fifo_data = IsRecording()` was called when `IsRecording()` returned false, but after that commit `g_record_fifo_data` never got changed back to false, so the check for `was_recording` only ever passed on the first fifolog recorded (even after stopping and starting a game).
There may still be another issue lurking, as I'm not sure if all broken fifologs were caused by recording multiple fifologs (for instance, on https://bugs.dolphin-emu.org/issues/13377, only one fifolog was initially uploaded, but it was affected by an issue with the same symptoms as this).
Instructions referencing registers r8-r15 take an additional byte to
encode. `reg_downcount` may be assigned to one of these registers, so it
is a small size win to store the downcount value in `RSCRATCH` first.

This value is used in a multiplication. The result of this
multiplication is then subtracted from m_base. By negating m_dec, we are
free to use an addition instead.
On x64, this saves an instruction.
Split the "welcome" messages letting players know achievements are active into a separate method that gets called (currently) after a number of frames to ensure that the emulator has started properly and has somewhere to display the messages.
A new tab is added to the Achievements dialog to chart out the leaderboards in a table. Each row of the table contains the leaderboard information and up to four relevant entries, varying based on how many entries are in the leaderboard, whether or not the player has a submitted score, and where in the leaderboard the player's score is.
FetchBoardInfo is called (via the work queue asynchronously) on a leaderboard every time it is activated or submitted to. It makes two calls to the RetroAchievements API for fetching leaderboard info, one that requests the top four entries in the leaderboard and another that requests the player's entry, the two entries above the player and the two entries below. All of these are inserted into a single map (resolving any overlaps) so the result can be exposed to the UI.
The leaderboard map created here contains information useful to displaying leaderboard stats in the Achievement dialog, including each leaderboard's name and description and a partial list of entries for display. The entire map is exposed to the UI in a single call for simplicity.
Both of these functions access `m_game_data` and don't lock themselves, so they must be called in a way that guarantees that `m_game_data` is not modified during the call.
Scope issue in the event callback from `rc_runtime_do_frame()`. The pointer points to a variable on the stack from inside `rc_runtime_do_frame()`, so that's a race condition between the thread calling `rc_runtime_do_frame()` and the event queue thread.
Added handling to Achievement Progress Events, which are generated when an achievement with a Measured field updates in value. For example, an achievement for collecting 120 stars will throw this event when the player collects each star, and with this handling, the player will get a message on screen informing them of this progress. This message will only appear if the newly added RA_PROGRESS_ENABLED setting is true.
A deep-copy method CopyReader has been added to BlobReader (virtual) and all of its subclasses (override). This should create a second BlobReader to open the same set of data but with an independent read pointer so that it doesn't interfere with any reads done on the original Reader.
As part of this, IOFile has added code to create a deep copy IOFile pointer onto the same file, with code based on the platform in question to find the file ID from the file pointer and open a new one. There has also been a small piece added to FileInfo to enable a deep copy, but its only subclass at this time already had a copy constructor so this was relatively minor.
The achievement badges will now have a blue or gold border to identify whether they have been unlocked in softcore or hardcore mode. Similarly, the game badge will have a blue border if all achievements have been unlocked in either mode or a gold border if all achievements have been unlocked in hardcore mode.
Provided the badges are turned on in the settings, each achievement will have a badge next to it on the progress tab. There are different badges for locked and unlocked (usually locked is grayscale while unlocked is in color but not necessarily) and the badge chosen depends on the player's current unlock and hardcore status.
Provided badges are turned on, if there's a player logged in their RetroAchievements icon will appear next to their player info in the header of the Achievements dialog. If they're playing a game, so will the icon for the game. Also performed some refactoring and reorganizing to the header as a whole so that it looks consistent whether a game is running or not.
FetchBadges fetches all available badges (player, game, achievements) and stores them in AchievementManager's memory. New fields and accessors have been added as necessary. Badges for individual achievements are stored in the UnlockStatus map. The method is public so that the settings dialog can call it if badges are turned on after a game is started. Badges are deleted at game close and logout.
When evaluating whether jo.fastmem should be set to true, we check the
value of jo.fastmem_arena. However, due to a change made in 28e8117b90,
jo.fastmem_arena wasn't set until after the first time we set
jo.fastmem, so jo.fastmem would end up always being false until the next
time RefreshConfig was called.
Fixes https://bugs.dolphin-emu.org/issues/13364.
Image requests from RetroAchievements have a slightly different format from other requests, on account of being GET calls that return strings of image data, so this is a separate function that makes such calls. To handle this, I create a BadgeStatus object that ties each badge to a boolean flag for whether it is loaded and thus usable.
When the inverted depth range is unsupported and zRange is greater than farZ then min_depth becomes a negative value and far_depth will then exceed a depth of 1.0 (which is outside the scope of most backends and greater than GX_MAX_DEPTH of the console).
This happens when the backend supports depth clamping the min_depth is not clamped to zero.
And in order to avoid a double dereference in the dispatcher, directly store
the normalEntry in the map.
The index to the block map becomes ((((DR<<1) | IR) << 30) | (address >> 2)).
This has been chosen since the msr bits change less often than the address,
thus we keep nearby entries together.
Also do not call the C dispatcher in case the assembly dispatcher didn't
find a block, since it wouldn't find a block either due to the 1:1 mapping,
except when falling back to the non shm segment lookup table.
We had two nearly identical copies of the gather pipe exception checking
code right next to each other, with the only difference being the
register used. Let's unify them, like in Jit64.
This bug has been lurking in the code ever since I added the discard
functionality. It doesn't seem to be triggered all that often,
and on top of that the emitted code only runs conditionally, so I'm not
sure if people have been affected by this bug in practice or not.
We need to check for the address of the *previous* instruction, because
checking fifoWriteAddresses happens not at the end of the instruction
that triggered it but at the start of the next instruction.
This refactors the Rich Presence generation to store to a member field that can be exposed to the UI to display the Rich Presence in the achievement header. It still updates at its original rate of once per two minutes, but calls an update on the dialog when that ticks.
Moved AchievementManager Init further down in the MainWindow constructor; its original position was because it had an impact on the contents of the menu bar, and this is no longer the case.
Whenever JitBaseBlockCache::Clear() got called, it threw away the memory mapping for the fast block map and created a new one. This new mapping typically got mapped at the same address at the old one, but this is not guaranteed. The pointer to the mapping gets embedded in the generated dispatcher code in Jit64AsmRoutineManager::Generate(), which is only called once on game boot, so if the new mapping ended up at a different address than the old one, the pointer in the ASM pointed at garbage, leading to a crash.
This fixes the issue by guaranteeing that the new mapping is mapped at the same address.
While both fastmem and the BLR optimization depend on fault handling,
the BLR optimization doesn't depend on fastmem, and there are cases
where you might want the BLR optimization but not fastmem. For me
personally, it's useful when I try to use a debugger on Android and have
to disable fastmem so I don't get SIGSEGVs all the time, but it would be
especially useful for iOS users.
When we execute a JIT block, we have to make sure that both the PC and
the DR/IR bits of MSR are the same as they were when the block was
compiled. When jumping to a block from the dispatcher, this is done in
the way you would expect: By checking the PC and the relevant MSR bits.
However, when returning to a block using the BLR optimization, we only
check the PC. Checking the MSR bits is done by instead resetting the
stack when the MSR changes, making PC checks afterwards fail.
Except... We were only resetting the stack on rfi instructions. There
are actually many more ways for the MSR to change, and we weren't
covering those at all. I looked into resetting the stack on all of them,
but it would be pretty cumbersome both in terms of writing the code and
in terms of how often at runtime we'd have to reset the stack, so I
think the better option would be to check the MSR bits along with the
PC. That's what this commit implements.
Because CPU thread config changed callbacks are no longer instant,
g_Config.iEFBScale doesn't yet contain the new value when the hotkey OSD
code tries to read it.
Should fix https://bugs.dolphin-emu.org/issues/13343.
There's no reason not to allow this now that these settings are
cleanly integrated into the new config system. (Actually, maybe
we could even have done this before the previous commit...)
This fixes a problem where changing the JIT debug settings on
Android while a game was running wouldn't cause the changed settings
to apply to code blocks that already had been compiled.
Resolve warning caused by using values from two different enums in a
conditional expression which was deprecated in c++20.
The warning in question is clang -Wdeprecated-anon-enum-enum-conversion
and gcc -Wenum-compare.
We had one implementation of this type of data structure in Arm64Emitter
and one in VideoCommon. This moves the Arm64Emitter implementation to
its own file and adds begin and end functions to it, so that VideoCommon
can use it.
You may notice that the license header for the new file is CC0. I wrote
the Arm64Emitter implementation of SmallVector, so this should be no
problem.
Modify PPCSTATE_OFF and PPCSTATE_OFF_ARRAY macros when using GCC to
avoid useless log spam. Specifically, use a consteval lambda with gcc
_Pragma statements to disable the -Winvalid-offsetof warning inside the
macros.
Each successful build (and many failing ones) on the Android buildbot
generates almost 300 cases of -Winvalid-offsetof, resulting in thousands
of lines of log spam per build. In addition to bloating the log filesize
these spurious warnings make it harder to find actual warnings.
These warnings are generated by calls to the macros PPCSTATE_OFF and
PPCSTATE_OFF_ARRAY, which in turn are used by many other macros used by
the JIT. The ultimate cause is that offsetof is only conditionally
supported on non-standard-layout types, which includes the PowerPCState
struct.
To address potential questions of whether there's a better way to handle
this:
The obvious solution would be to modify PowerPCState so that it does
have a standard layout. This is unfortunately impractical.
To have a standard layout a type can only contain other types with
standard layouts. None of the stl containers are guaranteed to have
standard layouts, and PowerPCState contains a std::tuple and std::array.
PowerPCState also contains a PowerPC::Cache and InstructionCache which
themselves contain std:arrays and std::vectors.
Furthermore InstructionCache derives from Cache, and a derived class can
only have standard layout if at most one class in its hierarchy has a
non-static data member, but both classes have such members. Making
InstructionCache have a standard layout would require duplicating all
the functionality of Cache so it no longer derived from it, as well as
replacing the stl containers. This might require having a raw pointer to
said containers, with the manual memory management that implies.
All of that would be much more disruptive than would be justified to get
rid of some warnings (however annoying they might be). This is
compounded by the fact that PowerPCState hasn't had a standard layout
for a long time, if ever, and if the PPCSTATE_OFF macros weren't working
reliably it would have become obvious a long time ago.
As to why I picked the lambda solution over other potential changes:
- Keeping the define as-is and wrapping some gcc #pragmas around it
doesn't work because the pragmas don't get included when the define is
substituted to the call site.
- Keeping the define as a non-lambda expression and using inline
_Pragma() statements would ideally be better and works fine for msvc,
but fails for GCC with "'#pragma' is not allowed here".
- Turning off -Winvalid-offsetof globally for gcc would work, but there
might be other contexts where offsetof is problematic and GCC seems to
be the only compiler warning about it.
This does require another register, but we skip having to use shifted
ADD, which takes two cycles on some CPUs, and we gain instruction-level
parallelism.
This was because the shader uniforms between the pixel and vertex shaders
were willingly left different, to avoid filling the vertex shader with unnecessary
params. Turns out all backends are fine with this except OGL.
The new behaviour is now much more consistent and well explained,
the "default" shaders are the ones that always run, and the non default
ones are the user selected ones (if any).
Turns out that we have two subsystems that want to register CPU thread
callbacks from a different thread than the CPU thread: FreeLookConfig
and VideoConfig. Both seem to happen from the host thread before the CPU
thread starts, so there's no thread safety issue. But ideally, if we
want to allow registering callbacks from threads other than the CPU
thread, we should make registering callbacks actually thread-safe. This
is an unsolved problem for the regular Config system, so I would like to
leave it outside the scope of this PR.
This fixes a problem that started happening in CoreTimingTest after the
previous commit. CPUThreadConfigCallback registers a Config callback
only once per run of the process, but CoreTimingTest calls
Config::Shutdown after each test, and Config::Shutdown was clearing all
callbacks, preventing the callback from running after that.
In theory, our config system supports calling Set from any thread. But
because we have config callbacks that call RunAsCPUThread, it's a lot
more restricted in practice. Calling Set from any thread other than the
host thread or the CPU thread is formally thread unsafe, and calling Set
on the host thread while the CPU thread is showing a panic alert causes
a deadlock. This is especially a problem because 04072f0 made the
"Ignore for this session" button in panic alerts call Set.
Because so many of our config callbacks want their code to run on the
CPU thread, I thought it would make sense to have a centralized way to
move execution to the CPU thread for config callbacks. To solve the
deadlock problem, this new way is non-blocking. This means that threads
other than the CPU thread might continue executing before the CPU thread
is informed of the new config, but I don't think there's any problem
with that.
Intends to fix https://bugs.dolphin-emu.org/issues/13108.
In std::string, you can store strings using any encoding, but in Dolphin
we have decided to use UTF-8. The problem is that if you convert between
std::string and std::filesystem::path using the built-in methods, the
standard library will make up its own assumption of what encoding you're
using in the std::string. On most OSes this is UTF-8, but on Windows
it's whatever the user's code page is.
What I believe is the C++ standard authors' intended solution to this is
to use std::u8string instead of std::string, but that's a big hassle to
move over to, because there's no convenient way to convert between
std::string and std::u8string. Instead, in Dolphin, we have added helper
functions that convert between std::string and std::filesystem::path in
the manner we want. You *always* have to use these when converting
between std::string and std::filesystem::path, otherwise we get these
kinds of encoding problems that we've been having with custom textures.

The previous list had some issues. A lot of variant id's were set to 0x0000. Althought this works for some figures, on a technicallity implemented into the games, they are technically wrong and don't result in exactly the same experience as the real figures. For example, the previous small fry got a "series 1" text in the summon screen. The real small fry does not have this. I also added figure types so I can add seperate generation logic later.
The Kaos element only applies to 3 items. So, I decided to throw it under others since it's not listed as an element in the manual and you can easily search for Kaos
Android interprets char as unsigned char, so comparing with 0 triggers a
tautological-unsigned-char-zero-compare warning.
Casting c to an unsigned char and removing the comparison with 0
resolves the warning while needing one less comparison on all platforms.
Verify that DXFramebuffer's integer RTV descriptor's cpu_handle has been
allocated before using it, and if it hasn't use the non-integer RTV
descriptor instead. This fixes a Dolphin crash in Twilight Princess, and
possibly other games (Issue 13312).
As an optimization to save space in the descriptor heap, DXFramebuffer's
integer descriptor is only initialized if the given abstract texture
format has different integer and non-integer RTV formats. This
previously wasn't accounted for by GetIntRTVDescriptorArray, which could
cause DX12::Gfx::BindFramebuffer to call OMSetRenderTargets with an
invalid descriptor which would lead to a crash.
Triggering the bug was fortunately rare because integer formats are only
used when blending is disabled and logic ops are enabled. Furthermore,
the standard integer abstract format is RGBA8 which has different
integer and non-integer RTV formats, causing the integer descriptor to
be initialized and avoiding the bug.
The crash started appearing in a2702c6 because it changed the
swapchain's abstract texture format from RGBA8 to RGB10_A2. Unlike
RGBA8, RGB10_A2 has the same integer and non-integer RTV formats and so
the bug can be triggered if the other requirements are met.
Should fix https://bugs.dolphin-emu.org/issues/13178.
Jit64 doesn't need to do this because it stores PC directly into
ppcState instead of first storing it in a register.
Now block link nearcode is back to a length of three instructions.
Unfortunately, the code I'm adding to Jit.cpp ends up being a bit messy
because we need to handle the case of already being in farcode...
Jumping between linked blocks currently works as follows: First, at the
end of the first block, we check if the downcount is greater than zero.
If it is, we jump to the `normalEntry` of the block. So far so good. But
if the downcount wasn't greater than zero, we jump to the `checkedEntry`
of the block, which checks the downcount *again* and then jumps to
`do_timing` if it's less than zero (which seems like an off by one error
- Jit64 doesn't do anything like this). This second check is rather
redundant. Let's jump to `do_timing` where we previously jumped to
`checkedEntry`.
Jit64 doesn't check the downcount on block entry. See 5236dc3.
I initially thought the 0x01 side was both sides (equavalent to just C. However, this turned out to be something I forgot I implemented in my personal interface. 0x01 does not seem to change any colors.
Recently discovered how exactly the last 2 bytes of the J command for timing data
using portmapping with hosting while using traversal server (which is possible by checking the option while under "direct connect" and flipping back to traversal server) causes dolphin to request a mapping to external port 0.
In UPnP a mapping to external port 0 is actually the wildcard, which means that connection requests on all
external ports (that are not otherwise mapped) will be forwarded to the client.
Additionally it seems like using port mapping with traversal server is probably not expected behavior, as the option checkbox disappears when traversal server is used.
Dolphin no longer supports Windows 7, so the fact that there are (were?)
more people who use Windows 7 than who use a GPU that doesn't support
the required feature is no longer relevant.
By misusing Config, this netplay-related code opened up a race condition between Config::OnConfigChanged() and SerialInterface::SerialInterfaceManager::UpdateDevices() that could cause iterator invalidation.
GCAdapter::UseAdapter() reads s_is_adapter_wanted, which gets
initialized by config_guard.~ConfigChangeCallbackGuard(). So we must
wait until after destroying the config guard to know whether we have any
controllers set to GC Adapter.
Expanded the use of the lock mutex already used for loading the player's existing unlock status to guard against races involving the Achievements dialog window reading from data AchievementManager might be in the process of updating. The lock has been exposed publicly and the AchievementsWindow uses it in its UpdateData method, and anywhere else that might modify data used to render that window has also been wrapped with it.
AchievementManager now has a SetUpdateCallback method for providing a single universal callback for anytime something important changes in the achievement state, such as logging in/out, game load/close, or events such as achievement unlocks. AchievementsWindow sets this callback in its own init to its UpdateData method so that the AchievementsWindow gets updated when one of these changes takes place.
This widget is a tab in the AchievementsWindow that displays the player's current achievement progress: which achievements are locked or unlocked, and the progress of achievements that have progress metrics.
This widget displays a header on the AchievementsWindow dialog above the tabs that shows the currently logged in user (if there is one) and the game they are playing (if there is one).
Added some small methods to AchievementManager to expose useful data for displaying in an achievement UI. Also moved a couple things from private to public for the same purpose.
1 ) When first opened, the (user selected) post process shader config widget would print the wrong values on the text label next to int range sliders. For example if the range was from 1 to 6, and the value loaded from the config was 1, the label would print 0 when first opened, to then start showing the correct value once the slider was first moved.
This mirrors the behaviour of the float slider code below:
```auto* const value_box = new QLineEdit(QString::asprintf("%f", m_config_option->m_float_values[i]));```
2 ) The defautl int slider value would also be set wrong on first load, as it was being divided by the slider max instead of the slider step amount (again, just like for the float implementation). This is a mistake I had made with my previous submission.
The ExpansionInterfaceManager::PauseAndLock function does nothing but
call other functions that have no effect.
ExpansionInterfaceManager::PauseAndLock calls CEXIChannel::PauseAndLock,
which in turn calls IEXIDevice::PauseAndLock. None of the classes
deriving from IEXIDevice override PauseAndLock, and the implementation
in IEXIDevice does nothing.
Fixing all the places it's used turned out to be a more complicated task than anticipated. So let's remove this for now so we don't confuse users with cryptic error messages...
To further increase the accuracy of the post process phase, I've added (scRGB) HDR support, which is necessary
to fully display the PAL and NTSC-J color spaces, and also to improve the quality of post process texture samplings and
do them in linear space instead of gamma space (which is very important when playing at low resolutions).
For SDR, the quality is also slightly increased, at least if any post process runs, as the buffer is now
R10G10B10A2 (on Vulkan, DX11 and DX12) if supported; previously it was R8G8B8A8 but the alpha bits were wasted.
Gamma correction is arguably the most important thing as Dolphin on Windows outputted in "sRGB" (implicitly)
as that's what Windows expects by default, though sRGB gamma is very different from the gamma commonly used
by video standards dating to the pre HDR era (roughly gamma 2.35).
Additionally, the addition of HDR support (which is pretty straight forward and minimal), added support for
our own custom AutoHDR shaders, which would allow us to achieve decent looking HDR in Dolphin games without
having to use SpecialK or Windows 11 AutoHDR. Both of which don't necessarily play nice with older games
with strongly different and simpler lighting. HDR should also be supported in Linux.
Development of my own AutoHDR shader is almost complete and will come next.
This has been carefully tested and there should be no regression in any of the different features that Dolphin
offers, like multisampling, stereo rendering, other post processes, etc etc.

There's nothing going on with behavior here that would prevent these

Also better communicates that this function isn't intended to modify the

We want to have a low number of instructions between the LDP and the
MADD so that the MADD can start immediately after the LDP finishes

Replace the bool parameter force5bytes in J, JMP, and J_CC with an enum
class Jump::Short/Near. Many callers set that parameter to the literal
'true', which was unclear if you didn't already know what it did.
The base DebugInterface now depends on the Core's CPUThreadGuard, and
utilities in Common shouldn't be depending on Core facilities. So, we
can move this into the core library instead.
This doesn't need to be handled by translators, since they're not
user-displayed text or just don't need to be translated.
While we're at it, we don't need to copy each entry of the resulting
list.
We can utilize the fact that if swapping two instructions causes another
swap to become possible, that swap involves one of the two instructions
we just swapped. There's need to search for new swap opportunities as
far back as the beginning of the block; we can just go one step back.
Mesa (llvmpipe) only reports 4x MSAA, and doesn't report 2x (or 1x, but we implicitly add that). The old logic did not handle this correctly, causing selecting 4x to fail and fall back to None.
This also removes VideoUtils::GetAvailableAntialiasingModes, and thus VideoUtils entirely, as its only other function was removed in 1f74653501.
We can move the construction of the Diff instance into the body of the

While we're at it, we can move the symbol description string into the

-An assert would be erroneously thrown when shaders declared an array of 4 int or float options, despite 4 being the max supported (a simple <= / < mistake)
-When changing the type of a shader option (e.g. from bool to float), the serialization would be stuck appending the value from the previous option type, making the shader fail to build permanently until the cache were cleaned
DX12 would often crash when starting and stopping the emulation many times, due to the device enumerator failing for some reason. Checking for success fixes it.
I've received a report from an Android user with a gamepad (a "BSP-D3")
where one physical trigger is controlling two analog axes at the same

With this change, now the axis with the greatest smoothness is kept,
or both in case they have the same smoothness.

To maintain compatibility with some video encoders, the whole output buffer was scaled to be a multiple of 4.
This change makes it so that that rule only applies while actively recording (or taking screenshots, even if it might not be necessary for that case).
Somewhere in the process of getting the memory peeking right for achievements, the AchievementManager call to DoFrame went missing. This restores it properly.
AchievementSettingsWidget is a dialog widget in AchievementsWindow for handling RetroAchievements settings in the user interface.

AchievementsWindow now has a tabbed list that this is inserted into; other tabs will be in a later pull request.

Added OnScreenDisplay messages to HandleAchievementTriggeredEvent to display an extra congratulations message if the player has completed (unlocked all achievements in casual) or mastered (unlocked all achievements in challenge) the game. This also uses the display name retrieved when verifying credentials, which has now been added as a member field on AchievementManager.
Added an OnScreenDisplay message to LoadGameByFilenameAsync to display a message when a player starts a game with achievements, notifying them of their current score. The score displayed is challenge points if the player is in challenge mode or challenge + casual if the player is in casual mode. A second message tells the player which mode they are in. To match RetroAchievements' website interface, the messages are blue for casual and gold for challenge.
Added a TallyScore method to AchievementManager to calculate the player's current scores (soft and hard) against the total number of points across all achievements. Includes a PointSpread structure to hold all points and counts. The Unlock Map now includes point values for each achievement to aid in this calculation; this is populated at insert time, and Unofficial achievements are tallied as zero.
Added HandleLeaderboardStartedEvent with an OnScreenDisplay message when a player has triggered a leaderboard's failure conditions. The message includes the title of the achievement.
Added HandleLeaderboardStartedEvent with an OnScreenDisplay message when a player has triggered a leaderboard's start conditions. The message includes the title of the achievement.
Added an OnScreenDisplay message to HandleLeaderboardTriggeredEvent to display a message when a player has completed a leaderboard. The message includes the title of the achievement and the player's score/time.
Added an OnScreenDisplay message to HandleAchievementTriggeredEvent to display a message when a player has unlocked an achievement. The message includes the title of the achievement and its point value based on the game data. To match RetroAchievements' website interface, the message is blue if the unlock is casual and gold for challenge.

By using a shm memory segment for the fast_block_map that is sparsely
allocated (i.e. on write by the OS) instead of a statically allocated
array we can make the block lookup faster by:
* Having a bigger space available for lookup that doesn't take up
too much memory, because the OS will only allocate the needed
pages when written to.
* Decrease the time spent to lookup a block in the assembly dispatcher
due to less comparisions and shorter code (for example the pc check
has been entirely dropped since only the msrBits need to be validated).
When the JIT block cache is full the shm segment will also be released
and reallocated to avoid allocating too much memory. It will also be
reset when the instruction cache is flushed by the PPC code to avoid
having stale entries.
Also fallback to the original method in case the memory segment couldn't
be allocated.
A comment removed by this commit gives two reasons for listening to
slave devices, both of which no longer apply:
- "Only slaves emit raw motion events": perhaps this was true when the
comment was written, but now master devices provide raw motion events
along with the other raw events.
- "Selecting slave keyboards avoids dealing with key focus": we get raw
key events regardless of the focus.
Listening to both master and slave devices results in duplicate raw
events. For button and key events, that's a tiny waste of time setting
the update flag a second time, but for raw mouse events the raw motion
will be processed twice. That makes this commit a user-facing change.
In X, the ButtonPress events generated when a mouse button is pressed
have a special property: if they don't activate an existing passive
grab, the X server automatically activates the "implicit passive grab"
on behalf of the client the event is delivered to. This ensures the
ButtonRelease event is delivered to the same client even if the pointer
moves between windows, but it also causes all events from that pointer
to be delivered exclusively to that client. As a consequence of the
implicit passive grab, for each window, only one client can listen for
ButtonPress events; any further listeners would never receive the event.
XInput 1 made the implicit grab optional and explicit by allowing
clients to listen for DeviceButtonPress events without
DeviceButtonPressGrab events. XInput 2 does not have a separate grab
event class, but multiple clients can listen for XI_ButtonPress on the
same window. When a button is pressed, the X server first tries to
deliver an XI_ButtonPress event; if no clients want it, then the server
tries to deliver a DeviceButtonPress event; if no clients want it, then
the server tries to deliver a ButtonPress event. Once an event has been
delivered, event processing stops and earlier protocol levels are not
considered. The reason for this rule is not obviously documented, but
it is probably because of the implicit passive grab; a client receiving
a ButtonPress event assumes it is the only client receiving that event,
and later protocols maintain that property for backward compatibility.
Before this commit, Dolphin listened for XI_ButtonPress events on the
root window. This interferes with window managers that expect to
receive ButtonPress events on the root window, such as awesome and
Openbox. In Openbox, applications are often launched from a menu
activated by clicking on the root window, and desktops are switched by
scroll wheel input on the root window. This makes normal use of other
applications difficult when Dolphin is open (though Openbox keyboard
shortcuts still work). Conversely, Dolphin only receives XI_ButtonPress
events for clicks on the root window or window decorations (title bars),
not on Dolphin's windows' content or the render window. In window
managers that use a "virtual root window" covering the actual root
window, such as Mutter running in X, Dolphin and the window manager do
not conflict, but clicks delivered to other applications using XInput2
(for testing, try xinput --test-xi2) are not seen by Dolphin, which is
relevant when background input is enabled.
This commit changes Dolphin to listen for XI_RawButtonPress (and the raw
versions of other events); Dolphin was already listening to XI_RawMotion
for raw mouse movement. Raw events are always and exclusively delivered
to the root window and are delivered to every client listening for them,
so Dolphin will not interfere with (or be interfered with by) other
applications listening for events.
As part of being raw, button numbers and keycodes in raw events have not
had mapping applied. If a left-handed user swapped the left and right
buttons on their mouse, raw events do not reflect that. It is possible
to query the mappings for each device and apply them manually, but that
would require a fair amount of code, including listening for mapping
changes.
Instead, Dolphin now uses the events only to set a "changed" flag, then
queries the current button and key state after processing all events.
Dolphin was already querying the pointer to get its absolute position
and querying the keyboard to filter the key bitmap it created from
events; now Dolphin also uses the button state from the pointer query
and uses the keyboard query directly.
Queries have a performance cost because they are synchronous requests to
the X server (Dolphin waits for the result). Commit 2b640a4f made the
pointer query conditional on receiving a motion event to "cut down on
round trips", but commit bbb12a75 added an unconditional keyboard query,
and there have apparently been no performance complaints. This commit
queries the pointer slightly more often (on button events in addition to
motion), but only queries the keyboard after key events, so the total
rate of queries should be substantially reduced.
Fixes: https://bugs.dolphin-emu.org/issues/10668
We need XInput 2.1 to get raw events on the root window even while
another client has a grab. We currently use raw events for relative
mouse input, and upcoming commits will use raw events for buttons and
keys.
FSCore implements the core functionality that can also be used outside of emulation. FSDevice implements the IOS device and is only available during emulation.

DoFrame is a function called every frame by the emulator so that rcheevos can be properly updated and processed. It requires a memory peeker and an event handler to be passed in; the memory peeker is called repeatedly each frame to measure what's in memory and compare to achievement definitions, and any events thrown by that comparison are sent to the event handler.
Also, DoFrame checks for the current system time to determine when to ping rich presence. Rich Presence on the RetroAchievements website updates every two minutes, so if two minutes have elapsed since the previous ping, another ping is sent.
GenerateRichPresence calls rc_runtime_get_richpresence in rhceevos on the achievement runtime to get the current Rich Presence string, a description of the player's current in-game state based on its memory as fed into a custom-developed script downloaded via FetchGameData. This gets passed into PingRichPresence, but is separated into its own method so it can be used elsewhere locally.
MemoryPeeker is a function passed by pointer into rcheevos DoFrame functionality that forms the lynchpin of the rcheevos runtime - it provides the interface by which rcheevos accesses memory and determines if the fields provided by achievement, leaderboard, and rich presence definitions are meeting the criteria needed.
AchievementEventHandler simply checks which kind of event is triggered and calls the appropriate function. Its primary purpose is as a function to be pointed to.
HandleAchievementTriggeredEvent is an asynchronous method that processes an event and places a synchronous AwardAchievement call on the work queue. In the process, it also updates the unlock map and makes the ActivateDeactivateAchievement call to determine and adjust the achievement's current active state.
PingRichPresence makes a "ping" API request to the RetroAchievements website with the provided RichPresence string parameter. While there has been talk about tying ping in with session, in its current state the primary purpose of ping is to send the player's Rich Presence to the website.
AwardAchievement performs the API call to notify the site that an achievement has been unlocked. As one of the parameters is the game hash (something I overlooked previously; I thought it was the game ID) this change also moves the game hash into a member field.

The old tooltip description box used GraphicsWidget to provide shared

GraphicsInteger is used by the panes in the Graphics config window to
create spin boxes that change their associated config setting, and
update their own state when something else changes the config setting.
Despite its current name nothing about this class is particular to the

purpose. This should also make it less confusing when ConfigIntegers
are added to other config windows.

m_xrr_config is initialized in MainWindow which still uses it to toggle

GraphicsChoice is used by the panes in the Graphics config window to
create combo boxes that change their associated config setting, and
update their own state when something else changes the config setting.
Despite its current name nothing about this class is particular to the
Graphics window, so renaming it to ConfigChoice better reflects its
purpose. This should also make it less confusing when ConfigChoices are
eventually added to the other config windows.
QApplication should parse and remove and args it recognizes
before dolphin starts inspecting the args.
This allows using e.g. -style <style> on the commandline.
PR #11183 regressed the lookup table reconstruction and, for some reason, added an else clause that clobbered the dCache whenever dCache emulation is turned on.
GraphicsBool is used by the panes in the Graphics config window to
create checkboxes that change their associated config setting, and
update their own state when something else changes the config setting.
Despite its current name nothing about this class is particular to the
Graphics window, so renaming it to ConfigBool better reflects its
purpose. This should also make it less confusing when ConfigBools are
eventually added to the other config windows.
In older versions of Dolphin GraphicsBoolEx was used to create a pair of
radio buttons selecting one of Virtual XFB and Real XFB, but this was
removed with the introduction of Hybrid XFB in 65cd085f.
In the meantime GraphicsRadioInt was introduced to allow for Graphics
radio buttons with multiple options, so GraphicsBoolEx is now redundant.
Previously this was using the default deleter (which just calls delete
on the pointer), which is incorrect, since the ENetHost instance is
allocated through ENet's C API, so we need to use its functions to
deallocate the host instead.
Before, any call of Settings::SetDebugModeEnabled(true) would show it. This means that if the debugging UI is enabled, but the user manually closed the code widget, then toggling any option on the interface pane (such as "Pause on Focus Loss") would cause the code widget to reappear. Additionally, closing and reopening dolphin did not call SetDebugModeEnabled, so the code widget did not reappear in that case (it only appeared after touching the interface pane). This is a bit silly, so now only enabling the debugger does it.
This also somewhat resolves an inconsistency introduced by the previous commit: prior to it, --debugger would call SetDebugModeEnabled(true) and thus show the code pane; after these commits, it does not, as it acts like a config change. This is a behavior difference, but not a particularly important one.
Before, Settings::SetDebugModeEnabled was used; this calls SetBaseOrCurrent() which will usually permanently change the base configuration setting for the debugger to true. Thus, the debugger would remain active even if the --debugger command line option was removed. Now, it remains active only for the current run, like other command-line options.
Note that SetBaseOrCurrent is also used by the "Show Debugging UI" option under Options -> Interface; this means that if the debugger is turned off (or off and then back on) by the user while --debugger is specified, this will be reset to whatever the base configuration had when Dolphin is closed and reopened. This behavior is consistent with the rest of the UI.
To my understanding, the --debugger option is something from 5.0 stable/DolphinWx where there was no way to toggle the debug UI in the settings (and the command-line option was the only way of enabling it). It's less useful nowadays.
This isn't used anywhere and not really a generic utility, so we can get
rid of it.
This also lets us remove MathUtil.cpp, since this was the only thing
within that file.
RetroAchievements Rich Presence is a script that is run periodically on a game's memory to provide a detailed text description of what the player is doing. Existing Discord presence on Dolphin would update a player's Discord status to say not just that they are using Dolphin but that they are playing, for example, Sonic Adventure 2 Battle; Rich Presence would detail that the player is in City Escape with 5 lives and 142 rings.
Activating this in the runtime simply entails loading that text script, as returned by the FetchGameData API call, into the runtime, here only determined by whether rich presence is enabled in the achievement settings. Deactivating this is done via the same rcheevos method by setting the rich presence to an empty string.
This activates or deactivates leaderboards in the rcheevos runtime similarly to achievements. The logic is much more straightforward - all leaderboards are active together; there is nothing requiring some leaderboards to be active while others are unactive, and even a leaderboard that has been submitted to in this session is still active to be submitted to again. The only criteria are that leaderboards must be enabled in the settings, and hardcore mode must be on, the latter of which is false until a future PR.
LoadUnlockData and ActivateDeactivateAchievements are the public API components responding to the FetchUnlocks and A/DAchievement (singular) private methods.
LoadUnlockData is asynchronous and performs both a hardcore and a softcore unlock call, updating the unlock map and the active status of any achievements returned from these calls.
ActivateDeactivateAchievements calls ActivateDeactivateAchievement on every achievement ID found in m_game_data, initializing the unlock map for each ID if not already found.
Both of these are currently called in LoadGameByFilenameAsync once the game has been loaded properly. There's a lock around this, to ensure that the unlock map is initialized properly by ActivateDeactivate Achievements before FetchUnlockData makes modifications to it without stalling the async portions of FetchUnlockData.
FetchUnlockData is an API call to RetroAchievements that downloads a list of achievement IDs for a game that the user has already unlocked and published to the site. It accepts a parameter for whether or not hardcore or softcore achievements are being requested, so that must be provided as well. Once it has the requested list on hand, it updates each achievement's status in the unlock map and will activate or deactivate achievements as necessary.
ActivateDeactivateAchievement is passed an Achievement ID as returned from the FetchGameData API call and determines whether to activate it, deactivate it, or leave it where it is based on its current known state and what settings are enabled.
Activating or deactivating an achievement entails calling a method provided by rcheevos that performs this on the rcheevos runtime. Activating an achievement loads its memory signature into the runtime; now the runtime will process the achievement each time the rc_runtime_do_frame function is called (this will be in a future PR) to determine when the achievement's requirements are met. Deactivating an achievement unloads it from the runtime.
The specific logic to determine whether an achievement is active operates over many fields but is documented in detail inside the function. There are multiple settings flags for which achievements are enabled (one flag for all achievements, an "unofficial" flag for enabling achievements marked as unofficial i.e. those that have logic on the site but have not yet been officially approved, and an "encore" flag that enables achievements the player has already unlocked) and this function also evaluates whether the achievement has been unlocked in hardcore mode or softcore mode (though currently every reference to the current hardcore mode state is hardcoded as false).
XInput2 was created to support multiple pointer/keyboard pairs (often
called MPX for multi-pointer X). Dolphin's XInput2 implementation has
always supported MPX by creating a KeyboardMouse object per master
pointer. Since commit bbb12a7, Dolphin's keyboard state is filtered by
the output of XQueryKeymap. As a core X function, XQueryKeymap queries
"the" keyboard, which by default is the first master keyboard. As a
result, Dolphin will ignore keys pressed on other master keyboards
unless the first master is simultaneously pressing the same keys.
XInput2 doesn't provide a function to query the keyboard state. There
is no XIQueryKeymap and the current state is not a member of the
XIKeyClassInfo returned by XIQueryDevice. Instead, XInput2 allows a
master pointer to be nominated as "the" pointer on a per-client basis,
with "the" keyboard automatically becoming the associated master
keyboard. The "documentation" [1] says passing None for the window is
only for debugging purposes, but it is documented in the
XISetClientPointer man page and seems to be the only way to query
keyboards beyond the first.
With this commit, Dolphin correctly reads keys from keyboards other than
the first master keyboard. To test, use the xinput command-line utility
to create a master pointer and reattach a keyboard to the associated
master keyboard.

LoadGameByFilenameAsync sets up a volume reader and hashes the volume, then uses that hash to make the three consecutive API requests to resolve hash, start session and load game data.
CloseGame resets the m_is_game_loaded flag, wipes the queue, and destroys all the game data responses.
FetchGameData is the big one - this retrieves the logic for all the achievements, leaderboards, and rich presence, and all the relevant metadata for the game.
Added a call to the RetroAchievements Start Session API to AchievementManager. This is primarily for client-side activation, so it doesn't return much of value, aside from its success/error information, but I'm storing the return structure in case this changes in the future.
Added the ResolveHash method to AchievementManager. This is a blocking function to send a hash string to the RetroAchievements server to verify it and get a game ID back.
This was previously copying each pair out of the vector returned by
GetInterfaceListInternal() when we just need to emplace the first entry
of each pair.
Fixes us forgetting to add its include directories, which could result in linking to a dylib from MacPorts while using the system's header, and failing to link because they use different function names
bSupports2DTextureStorageMultisample is completely unused, while bSupports3DTextureStorageMultisample is practically unused. In the past, these were checked and fell back to sampler2DMS instead of sampler2DMSArray on GLES 3.1, but this path was removed in f039149198 and Dolphin always uses array textures now.
See https://bugs.dolphin-emu.org/issues/13232; this was introduced in 7dde0c3c31. Apparently, providing a parent for a widget that is not visible makes your new widget visible when the parent is later made visible, in addition to managing the deletion of the widget; the documentation does not specify this (only that if the parent is visible you need to explicitly show it).
The inst.SIMM_16 change is for readability (though it also fixes a warning about potentially unintended uses of `||`).
The fallback change is because `b` is only meaningful for indexed instructions; this could theoretically lead to unintended fallbacks (but it seems unlikely).
The m_checkbox_lock_mouse QCheckBox was only conditionally being added
to the layout, leaving it unmanaged and leaking
Setting the parent will allow it to be managed.
The m_verbosity_debug button was only conditionally being added as
widget, this was done in order to hide the object, but this left it
unmanaged.
Unconditionally adding it to the layout and controlling it's visibility
will resolve these issues
Added AchievementManager class. Upon startup (currently only in DolphinQt), logs into RetroAchievements with the login credentials stored in achievements.ini.

Added AchievementSettings in Config with RA_INTEGRATION_ENABLED, RA_USERNAME, and RA_API_TOKEN. Includes code to load and store from Achievements.ini file in config folder.
The QByteArray returned by QString::toUtf8() was being freed so the char
pointer was pointing to freed memory.
Found via ASan, didn't notice any issues during normal runtime.
This was triggered after hitting a key combo with alt (ex. toggle
fullscreen) probably happens with others
This fixes a crash when recording fifologs, as the mutex is acquired when BPWritten calls AfterFrameEvent::Trigger, but then acquired again when FifoRecorder::EndFrame calls m_end_of_frame_event.reset(). std::mutex does not allow calling lock() if the thread already owns the mutex, while std::recursive_mutex does allow this.
This is a regression from #11522 (which introduced the HookableEvent system).
Adds the rcheevos library from RetroAchievements to the Dolphin Externals as a submodule. Change was verified to import correctly and build both via Visual Studio and via cmake ninja.
We have these for a reason. I think this also fixes a theoretical
problem when `ABI_PARAM1 == loop_counter` where the first MOV destroys
the second's value; I'm not sure if this can actually happen in practice
though.
Also works around a bug where CMake's ninja generator doesn't properly handle ||'s on POST_BUILD commands, making the || apply to the whole build like `<link> && custom0 || custom1`
Will manually controlling both an accelerometer and a gyroscope at the
same time be reasonable to do? No idea. Was this easy to implement
thanks to the input override system? Yes.
Fixes https://bugs.dolphin-emu.org/issues/12443.
In UpdateInput, lock m_devices_population_mutex before m_devices_mutex
to be consistent with other ControllerInterface functions. Normally the
former lock isn't needed in UpdateInput, but when a Wii Remote
disconnects it calls RemoveDevice which results in the mutexes being
locked in the wrong order.
This gets rid of a blocking operation, improving performance and fixing
https://bugs.dolphin-emu.org/issues/12893.
This also makes us no longer directly access the state of certain UI
elements from the CPU thread, which probably wasn't thread-safe but
doesn't seem to have caused any observable issues so far.
Up until now, there have been two settings on Android that stored the
selected Wii Remote extension: the normal one that's also used on PC,
and a SharedPreferences one that's used by the overlay controls to
determine what controls to show. It is possible for these two to end up
out of sync, and my input changes have made that more likely to happen.
To fix this, let's rework how the overlay controller setting works.
We don't want it to encode the currently selected Wii Remote extension.
However, we can't simply get rid of the setting, because for some Wii
games we need the ability to switch between a GameCube controller and a
Wii Remote. What this commit does is give the user the option to select
any of the 4 GameCube controllers and any of the 4 Wii Remotes. (Before,
controllers 2-4 weren't available in the overlay.) Could be useful for
things like the Psycho Mantis fight in Metal Gear Solid. I'm also
switching from SharedPreferences to Dolphin.ini while I'm at it.
It's missing a lot of features from the PC version for now, like
buttons for inserting functions and the ability to see what the
expression evaluates to. I mostly just wanted to get something in
place so you can set up rumble.

This is a small regression from KillRenderer, which caused duplicated
frames to be counted on the FPS counter when the "Skip Presenting
Duplicated Frames" option was disabled.
This way, Android (which will show groups in the order they're defined)
will show groups in a more logical order similar to DolphinQt.
The main thing that was annoying me was how early Rumble was for
Wii Remotes. Some of the other changes I'm making in this commit,
like the order of Shake/Tilt/Swing, are more arbitrary and were
made for consistency with DolphinQt. But there are also places
where I didn't go all the way with matching DolphinQt. Most notably,
DolphinQt puts sticks before buttons, but I don't see any reason
to do that for Android.
Unlike PCs, Android doesn't really have any input method (not counting
touch) that can reasonably be expected to exist on most devices.
Because of this, I don't think shipping with a default mapping for the
buttons and sticks of GameCube controllers and Wii Remotes makes sense.
I would however like to ship default mappings for a few things:
1. Mapping the Wii Remote's accelerometer and gyroscope to the device's
accelerometer and gyroscope. This functionality is useful mainly
for people who use the touchscreen, but can also be useful when
using a clip-on controller. The disadvantage of having this mapped
by default is that games disable pointer input if the accelerometer
reports that the Wii Remote is pointed at the ceiling.
2. Mapping GC keyboards for use with a physical keyboard, like on PC.
After all, there's no other way of mapping them that makes sense.
3. Mapping rumble to the device's vibrator.
Aside from the GC keyboards, this approach is effectively the same as
what we were doing before the input overhaul.
This is a battery-saving measure. Whether a sensor should be suspended
is determined in the same way as whether key events and motion events
should be handled by the OS rather than consumed by Dolphin.
When Android presents an input event to an app, it wants the app to
return true or false depending on whether the app handled the event or
not. If the event wasn't handled by the app, it will be passed on to
the system, which may decide to take an action depending on what kind
of input event it is. For instance, if a B button press is passed on to
the system, it will be turned into a Back press. But if an R1 press is
passed on to the system, nothing in particular happens.
It's important that we get this return value right in Dolphin. For
instance, the user generally wouldn't want a B button press to open
the EmulationActivity menu, so B button presses usually shouldn't be
passed on to the system - but volume button presses usually should be
passed on to the system, since it would be hard to adjust the volume
otherwise. What ButtonManager did was to pass on input events that are
for a button which the user has not mapped, which I think makes sense.
But exactly how to implement that is more complicated in the new input
backend than in ButtonManager, because now we have a separation between
the input backend and the code that keeps track of the user's mappings.
What I'm going with in this commit is to treat an input as mapped if
it has been polled recently. In part I chose this because it seemed
like a simple way of implementing it that wouldn't cause too many
layering violations, but it also has two useful side effects:
1. If a controller is not being polled (e.g. GameCube controllers in
Wii games that don't use them), its mappings will not be considered.
2. Once sensor input is implemented in the Android input backend,
we will be able to use this "polled recently" tracking to power down
the sensors at times when the game is using a Wii Remote reporting
mode that doesn't include motion data. (Assuming that the sensor
inputs only are mapped to Wii Remote motion controls, that is.)
Android doesn't let us poll inputs whenever we want. Instead, we
listen to input events (activities will have to forward them to the
input backend), and store the received values in atomic variables
in the Input classes. This is similar in concept to how ButtonManager
worked, but without its homegrown second input mapping system.
ButtonManager is very different from how a normal input backend works,
and is making it hard for us to improve controller support on Android.
The following commits will add a new input backend in its place.
When that setting is enabled, m_xfb_entry is initially not present (during the phase where a shader compilation progress bar would be shown). The main path checks for m_xfb_entry, but the software renderer fallback path didn't.
Fixes another aspect of https://bugs.dolphin-emu.org/issues/13172.
Before, it used a fallback where it returned a default object, where the width and height were set to 0. Presenter::Initialize() used GetSurfaceInfo to set the backbuffer size, then used that size when initializing the on-screen UI (even for the software renderer, where the on-screen UI isn't currently present), which meant that ImGui got a window size of 0 and thus resulted in a failed assertion.
Although BindBackbuffer checks for size changes, it doesn't help because ImGui has already been initialized, and the size hasn't actually changed since initialization occured.
Fixes one aspect of https://bugs.dolphin-emu.org/issues/13172.
This second stack leads to JNI problems on Android, because ART fetches
the address and size of the original stack using pthread functions
(see GetThreadStack in art/runtime/thread.cc), and (presumably) treats
stack addresses outside of the original stack as invalid. (What I don't
understand is why some JNI operations on the CPU thread work fine
despite this but others don't.)
Instead of creating a second stack, let's borrow the approach ART uses:
Use pthread functions to find out the stack's address and size, then
install guard pages at an appropriate location. This lets us get rid
of a workaround we had in the MsgAlert function.
Because we're no longer choosing the stack size ourselves, I've made some
tweaks to where the put the guard pages. Previously we had a stack of
2 MiB and a safe zone of 512 KiB. We now accept stacks as small as 512 KiB
(used on macOS) and use a safe zone of 256 KiB. I feel like this should
be fine, but haven't done much testing beyond "it seems to work".
By the way, on Windows it was already the case that we didn't create
a second stack... But there was a bug in the implementation!
The code for protecting the stack has to run on the CPU thread, since
it's the CPU thread's stack we want to protect, but it was actually
running on EmuThread. This commit fixes that, since now this bug
matters on other operating systems too.
I also changed LoadConfig, but that change doesn't affect correctness,
it's only so it looks neat by matching SaveConfig.
This bug was added in 18a4afb053, the
commit that introduced DefaultValue::Disabled. The bug can't actually be
triggered in master, but it can be triggered in the Android input
overhaul PR.
The HLSL compiler incorrectly decides isnan can't be true, so this
workaround was originally added in 52c82733 but lost during the
conversion to SPIR-V.
This broke formatting the system memory; see https://bugs.dolphin-emu.org/issues/13176. After calling ticket.DeleteTicket(), ticket.m_bytes was 0-length, but calling ticket.IsV1Ticket() still attempted to read from m_bytes.
This was introduced in 2fd9852ca8, although it didn't actually cause a crash until 929fba08e7.
When faced with this error, users often don't try disabling dual core,
even though the error message suggests it. Perhaps the message is just
too long and lists too many things?
To try to improve the situation, I'm rewording the message and making it
say different things depending on what settings you are using.
The LEA that the signal handler is trying to undo the effects of is a
32-bit instruction, and the value in the register prior to the LEA is
also 32-bit, so the signal handler should use a 32-bit write.
(Actually, in the end this doesn't really matter, because the first
instruction that reads this value after backpatching is also a 32-bit
instruction...)
This resulted in the labels being solid black even when audio stretching is disabled the first time the settings are opened, but then properly being greyed out after changing a setting (even the audio backend or DSP emulation engine, not just whether audio stretching is enabled).
This very much isn't a build configuration that we're going to ship,
but I want to be able to tell people that they can build it on their
own if they really want to see how terribly it performs :)
Just like before, you'll need to edit two lines in app/build.gradle to
define ENABLE_GENERIC=ON and actually enable armeabi-v7a if you want an
armeabi-v7a build. This commit just fixes some compilations errors that
crop up if you do so.
Before these changes you could tell Dolphin to convert a game file into the same format it is already in, leading to the FileDialog using the input path as the default destination path
An unsuspecting user could then click Save and Dolphin would try to convert the input file by writing the destination file on top of it... leading to an I/O error and the input file being entirely removed
This fixes a regression from 592ba31. When `a` was a constant 0 and `b`
was a non-constant 0x80000000, the 32-bit negation operation would
overflow, causing an incorrect result. The sign extension needs to happen
before the negation to avoid overflow.
Note that I can't merge the SXTW and NEG into one instruction.
NEG is an alias for SUB with the first operand being set to ZR,
but "SUB (extended register)" treats register 31 as SP instead of ZR.
I've also changed the order for the case where `a` is a constant
0xFFFFFFFF. I don't think the order actually affects correctness here,
but let's use the same order for all the cases since it makes the code
easier to reason about.
This works around an Intel driver bug where, on D3D12 only, dual-source blending behaves incorrectly if the second source is unused on. This bug is visible in skyboxes in Super Mario Sunshine, which first draw clouds and sun flare in greyscale and then draw the sky afterwards with a source factor of 1 and a dest factor of 1-src_color (this results in the clouds being tinted blue). This process is done on an RGB888 framebuffer, so alpha update is disabled. (Color update is enabled; note that if you look at this in Dolphin's fifo analyzer, it won't be enabled because they use the BP mask functionality to only change the blending functions and not alpha/color update, for whatever reason.)
The previous code only updated the PLRU on cache misses, which made it so that the least recently inserted cache block was evicted, instead of the least recently used/hit one.
This regressed in 9d39647f9e (part of #11183, but it was fine in e97d380437), although beforehand it was only implemented for the instruction cache, and the instruction cache hit extremely infrequently when the JIT or cached interpreter is in use, which generally keeps it from behaving correctly (the pure interpreter behaves correctly with it).
I'm not aware of any games that are affected by this, though I did not do extensive testing.
Previously we would only backpatch overflowed address calculations
if the overflow was 0x1000 or less. Now we can handle the full 2 GiB
of overflow in both directions.
I'm also making equivalent changes to JitArm64's code. This isn't because
it needs it – JitArm64 address calculations should never overflow – but
because I wanted to get rid of the 0x100001000 inherited from Jit64 that
makes even less sense for JitArm64 than for Jit64.
This avoids a pseudo infinite loop where CodeWidget::UpdateCallstack
would lock the CPU in order to read the call stack, causing the CPU to
call Host_UpdateDisasmDialog because it's transitioning from running to
pausing, causing Host::UpdateDisasmDialog to be emitted, causing
CodeWidget::Update to be called, once again causing
CodeWidget::UpdateCallstack to be called, repeating the cycle.
Dolphin didn't go completely unresponsive during this, because
Host_UpdateDisasmDialog schedules the emitting of Host::UpdateDisasmDialog
to happen on another thread without blocking, but it was stopping certain
operations like exiting emulation from working.
This fixes a problem I was having where using frame advance with the
debugger open would frequently cause panic alerts about invalid addresses
due to the CPU thread changing MSR.DR while the host thread was trying
to access memory.
To aid in tracking down all the places where we weren't properly locking
the CPU, I've created a new type (in Core.h) that you have to pass as a
reference or pointer to functions that require running as the CPU thread.
This code doesn't need to be portable (since the goal is to have a smaller offset for x64 codegen), so if it's not supported there are other problems. Similar code exists in e.g. DSP.cpp.
While the NV extension is totally fine, the KHR extension should be able to support more hardware.
For NVIDIA, the hardware either supports both or neither, it just needs a driver from the last two years.
For AMD, the drivers from late 2022-12 seems to bring support for the KHR extension.
For Intel, the KHR is also supported for some years.
Frame duplicate detection was inverted. Huge problem for 60fps games
where it would see all frames as "duplicates" and nothing would ever be
presented.
