JIT code related to Branch Watch was emitted if the debugging UI was active: the emitted code would dynamically check whether Branch Watch is active.
However, this causes two problems:
1. It decreases performance by just having the debugging UI enabled
2. It clutters the host assembly in the JIT tab, making it harder to read (unaware readers will wonder what these instructions are for)
With this PR, code related to Branch Watch is emitted only if Branch Watch itself is active, fixing the issues above.
The JIT cache will now be wiped whenever the feature is toggled, causing a slight stutter. However, this isn't the kind of feature that is toggled over and over, so IMO it is an acceptable trade-off.
Call `OnStateChanged` when creating CheatsManager to update the AR and
Gecko code tabs with codes for the currently running game (if any).
Previously, creating CheatsManager while a game was running wouldn't
show any codes until the next time the core state changed (excluding
Starting or Stopping which had no effect).
Fixes https://bugs.dolphin-emu.org/issues/13977.
The functions SaveToSYSCONF and LoadFromSYSCONF contain checks for
whether emulation is running. The intent of this is that when we're
emulating a Wii, the emulated system may write to SYSCONF whenever it
likes and does not expect anything else to write to SYSCONF, so the
host code shouldn't access SYSCONF while emulation is ongoing. However,
Core::IsRunning is an imperfect proxy for whether we've handed over
control of SYSCONF to the emulated system yet, as the actual handover
happens at a slightly different point in time than when the emulation
state is changed. This usually isn't a problem, but in theory it could
be a determinism problem if a setting is changed right as emulation is
starting, or it could cause the emulated software to briefly misbehave
if a setting is changed right as emulation is stopping.
Things got worse in 72cf2bdb87 when I
replaced the Core::IsRunning calls with !Core::IsUninitialized. With
IsRunning, there was be a period of time where SYSCONF should have been
protected but wasn't. With !IsUninitialized, there was a period of time
where SYSCONF shouldn't have been protected but was, and crucially, this
period of time included the moments where we do setup and teardown of
the emulated NAND, which broke transferring SYSCONF settings between the
host and the guest. 72cf2bdb87 was
reverted because of this.
This commit adds a flag that we explicitly flip when control is handed
over to or from the emulated system. This protects the SYSCONF file
for exactly as long as is needed.
Changes it to select rows then extracts one item from each row to operate on. The behavior and data across each item in a row was already identical, so using rows doesn't change anything.
Previously, when an input device was connected or disconnected, we would
recreate all devices. This commit makes it so we only touch the relevant
device instead. This matters because recreating a device causes us to
drop all held buttons for that device. Due to Android only delivering
inputs as events, we're unable to poll for currently held buttons when
recreating a device.
This recently became a problem for users of Ayn devices due to a
firmware update. Every now and then, something about the display
viewports changes, triggering an update to an input device that I assume
is a touch input device. This input device isn't something users
normally map in Dolphin's controller settings, but it changing was
causing Dolphin to drop all held buttons for the device's built-in
gamepad as well as any other connected gamepads.
Add a minimum value for the automatic size of the performance metrics
graph. The graph can still be manually resized smaller than this limit.
This prevents the graph from automatically resizing itself to be too
small to contain the full graph and legend, which happened when using
native resolution with `Auto-Adjust Window Size` enabled.
Fix a bug causing the performance graph to not resize when the render
window changed size:
* When changing the render window size during emulation the performance
graph wouldn't update its size until the next emulation session.
* When changing the render window size with no emulation active (by
changing the Internal Resolution with Auto-Adjust Window Size enabled)
the performance graph wouldn't update its size until the second
emulation session after the change.
Before explaining why the bug happened, here are some details about Dear
ImGui (henceforth ImGui) for context:
* In order to allow programs to specify initial ImGui window sizes while
also allowing the user to resize them, `SetNextWindowSize` takes a
flag from the `ImGuiCond_` enum specifying under what circumstances
that function should actually have any effect.
* ImGuiCond_FirstUseEver causes ImGui to only apply the command when the
window doesn't have any saved size information for that session or in
the ini file specified by `ImGui::GetIO().IniFilename`. Since we set
that filename to `nullptr`, in practice the resize command is applied
on the first frame of each ImGui/emulation session.
* Qt saves the most recent size of the render window across emulation
(and even Dolphin) sessions, which is then used to set the initial
value of `ImGui::GetIO().DisplaySize` in the next emulation session.
* It takes multiple frames for the size of the render window to update
when changed by setting the internal resolution. This means that
`ImGui::GetIO().DisplaySize` will have a stale value in the
intervening frames, and specifically for the first few frames of
emulation if the resolution was changed beforehand.
When changing the resolution during emulation the call to
`SetNextWindowSize` had no effect because of the
`ImGuiCond_FirstUseEver` flag. `DisplaySize` would be updated several
frames later, and then the next emulation session would update the graph
size on its first frame.
When changing the resolution outside emulation and then starting a game,
the call to SetNextWindowSize on the first frame took effect but used
the stale value of `DisplaySize`. `DisplaySize` would be updated a few
frames later, but the graph wouldn't be resized until the first frame of
the second emulation session.
This commit fixes the issue by using the `ImGuiCond_Always` flag in the
performance graph's call to `SetNextWindowSize` when the render window
size changes.
In the unit test I'm adding in the next commit, I want to call
MemoryManager::Init, but initializing all the hardware that
MemoryManager::InitMMIO calls into would be cumbersome.
Calling MemoryManager::InitMMIO from MemoryManager::Init was a bit
strange anyway. Because MemoryManager::Init is called about halfway
through HW::Init, some of the hardware that MemoryManager::InitMMIO
calls into isn't initialized yet.
Most systems that Dolphin runs on have a page size of 4 KiB, which
conveniently matches the page size of the GameCube and Wii. But there
are also systems that use larger page sizes, notably Apple CPUs with
16 KiB page sizes. To let us create host mappings on such systems, this
commit implements combining guest mappings into host page sized mappings
wherever possible.
For this to work for a given mapping, not only do four (in the case of
16 KiB) guest mappings have to exist adjacent to each other, but the
corresponding translated addresses also have to be adjacent, and the
lowest bits of the addresses have to match. When I tested a few games,
the following percentages of guest mappings met these criteria:
Spider-Man 2: 0%-12%
Rogue Squadron 2: 39%-42%
Rogue Squadron 3: 28%-41%
So while 16 KiB systems don't get as much of a performance improvement
as 4 KiB systems, they do still get some improvement.
Removing and readding every page table mapping every time something
changes in the page table is very slow. Instead, let's generate a diff
and ask Memmap to update only the diff.
Page table mappings are only used when DR is set, so if page tables are
updated when DR isn't set, we can wait with updating page table mappings
until DR gets set. This lets us batch page table updates in the Disney
Trio of Destruction, improving performance when the games are loading
data. It doesn't help much for GameCube games, because those run tlbie
with DR set.
The PowerPCState struct has had its members slightly reordered. I had to
put pagetable_update_pending less than 4 KiB from the start so AArch64's
LDRB (immediate) can access it, and I also took the opportunity to move
some other members around to cut down on padding.
Previously we've only been setting up fastmem mappings for block address
translation, but now we also do it for page address translation. This
increases performance when games access memory using page tables, but
decreases performance when games set up page tables.
The tlbie instruction is used as an indication that the mappings need to
be updated.
There are some accuracy downsides:
* The TLB is now effectively infinitely large, which matters if games
don't use tlbie when modifying page tables.
* The R and C bits for page table entries get set pessimistically rather
than when the page is actually accessed.
No games are known to be broken by these inaccuracies, but unfortunately
the second inaccuracy causes a large performance regression in Rogue
Squadron 3. You still get the old, more accurate behavior if Enable
Write-Back Cache is on.
It turns out that it is possible to create a login alias in RetroAchievements
such that you can log in with a username that doesn't match your display name.
AchievementManager was treating this as a synchronization error, but this is
desired behavior, so this removes the check.
Remove unused vector `controller_names` from `LoadConfig` and
`SaveConfig`. The vector has names added to it but they're never used.
Prior to d03f9032c1 these vectors were
passed to `DynamicInputTextureManager::GenerateTextures`, but that
commit removed those calls.
Yellow squiggly lines begone!
Done automatically on .cpp files through `run-clang-tidy`, with manual corrections to the mistakes.
If an import is directly used, but is technically unnecessary since it's recursively imported by something else, it is *not* removed.
The tool doesn't touch .h files, so I did some of them by hand while fixing errors due to old recursive imports.
Not everything is removed, but the cleanup should be substantial enough.
Because this done on Linux, code that isn't used on it is mostly untouched.
(Hopefully no open PR is depending on these imports...)
This improves my PC's performance on RS2 Hoth by... 0.1% or so, which I
think is within the margin of error. But this change also cuts down on
boilerplate.
If the call to `Open` a perf map fails don't set `s_is_enabled` (though
it could already be true if you're also using VTUNE) and don't call
`std::setvbuf` with a null stream.
Also fix a typo in a comment (`if` -> `in`)
If all inputs to an fmadds instruction (including cousins like fmsubs,
fnmadd...) are single-precision, then the result is identical between a
double-precision calculation with an error-free transform (whether the
calculation is fused or not) and a single-precision FMA instruction
(must be fused). So as a performance optimization in JitArm64, if we
were going to use double precision with EFT but the inputs are singles,
instead we'll use a normal single-precision FMA instruction without
anything extra. This lets us skip both the EFT and double-to-single
conversions.
Also renaming `inaccurate_fma` to `nonfused` because it's confusing that
`inaccurate_fma` and `m_accurate_fmadds` have such similar names
despite controlling separate things.
If result_reg is set to a temporary register instead of VD because of
accurate NaNs, there's no need to allocate a secondary temporary
register because of inaccurate FMA.
TextureCacheBase::LoadImpl has a hot path where the passed-in
TextureInfo never gets used. Instead of passing in a TextureInfo, let's
pass in the stage and create the TextureInfo from the stage if needed.
This unlocks somewhere above an additional 4% performance boost in the
Hoth level of Rogue Squadron 2 on my PC. Performance varies, making it
difficult for me to measure, so treat this as a very approximate number.
When we're emulating single-precision FMA using an FMA instruction,
there's no precision benefit from using a double-precision instruction,
assuming all inputs are single-precision. But when we're emulating
single-precision FMA using separate multiplication and addition
instructions, there is.
This change increases the precision of inaccurate FMA to the same level
as Jit64, which matters since the only reason we have the inaccurate
FMA mode is for sync compatibility with Jit64.
The check only happened if `USE_VTUNE` wasn't defined, and in that case
it was immediately followed by the same check again.
The check used to avoid an unnecessary call to `StringFromFormatV` in
certain circumstances, but that call was removed in
be81fe86e1.
Building on macOS with a recent CMake version would result in the
following error:
CMake Error at Source/Core/MacUpdater/CMakeLists.txt:48 (add_custom_command):
The following keywords are not supported when using
add_custom_command(TARGET): DEPENDS
As it turns out, this form of `add_custom_command` does not accept
DEPENDS, but versions of CMake prior to 3.31 silently dropped it.
The TextureInfo constructor creates a vector of MipLevels. This could be
good for performance if MipLevels are accessed very often for each
TextureInfo, but that's not the case. Dolphin creates thousands of
TextureInfos per second that it never accesses the mipmap levels of
because there's a hit in the texture cache, and in the uncommon case of
a texture cache miss, the mipmap levels only get looped through once.
To make the common case of texture cache hits as fast as possible, let's
not create a vector in the TextureInfo constructor. This commit
implements a custom iterator for MipLevels instead.
In my testing on the Death Star level of Rogue Squadron 2, this speeds
up TextureInfo::FromStage by 200%, giving an overall emulation speedup
of a bit over 1%. Results on the Hoth level are even better, with
TextureInfo::FromStage being close to 300% faster and overall emulation
being over 4% faster. (Single core, no GPU texture decoding.)
Profiling Dolphin using Heaptrack, this turns out to be the cause of
more than half of all temporary allocations. Though since it's in a
separate thread, I suppose it wasn't affecting performance very much.
Combined with the previous commit, this brings the TrampolineInfo struct
down to 48 bytes. This matters, because Jit64 has a big
std::unordered_map where it stores many megabytes of TrampolineInfo
entries.
The key saving comes from shrinking the len member from u32 to u16. It
should be safe to even turn it into a u8, but going that far brings no
additional savings due to how the padding works out.
By moving members of the OpArg struct around, we can cut down on how
much padding the struct needs. Now it has a size of 16 bytes, small
enough for function calls to pass it in two registers instead of on the
stack.
Re-added a line of code from a cancelled PR (that I thought was in
main already) that RetroAchievements uses to properly synchronize
memory reads and writes with the emulator frames. This appears to
fix some pretty major freezing and deadlocks in the RA dev tools.
CMake support for c++23 was added in 3.20.
Remove statements explicitly setting the following policies to NEW.
These policies were introduced in or before 3.20, and now that 3.20 is
the minimum version they will automatically have the NEW behavior.
Policy: Introduced in
CMP0079: 3.13
CMP0084: 3.14
CMP0091: 3.15
CMP0092: 3.15
CMP0099: 3.17
CMP0117: 3.20
Disable scanning c++ source files for module imports (introduced as
CMP0155 in 3.28) since we don't use modules and that policy triggers
build errors with Clang if the clang-scan-deps tool isn't installed.
cpp-ipc is explicitely only available on Windows, Linux, QNX, and FreeBSD. Trying to build dolphin on any another BSD such as OpenBSD or Haiku currently leads to failure because of this.
During my quest to rid Dolphin of the memory-unsafe GetPointer function,
I didn't realize that DSPHLE had its own set of memory access functions
that were essentially duplicating the standard ones. This commit gets
rid of them and replaces calls to them with calls to MemoryManager.
Move the constructor and destructor after the definition of the class
`Internal`.
This fixes an error generated by Clang from the destructor of
`std::unique_ptr<Internal>` when setting the standard version to c++23:
`invalid application of 'sizeof' to an incomplete type 'Metal::ObjectCache::Internal'`.
Fix an error generated by Clang from the destructor of
`std::unique_ptr<FileInfo> m_file_info` when setting the standard
version to c++23:
`invalid application of 'sizeof' to an incomplete type 'DiscIO::FileInfo'`
* This fixes some UI elements (3-dot menu background, status bar when scrolling down in settings) not following Material You colors.
* It doesn't cause any issues on Android versions without dynamic colors (tested on Android 9, 11, 16)
