Use VK_KHR_pipeline_executable_properties when enabled and available to
log statistics about the pipeline cache in a game.
For example, this is on Turing GPUs when generating a pipeline cache
from Super Smash Bros. Ultimate:
Average pipeline statistics
==========================================
Code size: 6433.167
Register count: 32.939
More advanced results could be presented, at the moment it's just an
average of all 3D and compute pipelines.
Everything else has a default constructor that does the straightforward
thing of initializing most members to a default value, except for the
size.
We explicitly initialize the size (and others, for consistency), to
prevent potential uninitialized reads from occurring. Particularly given
the largeish surface area that this struct is used in.
use_framelimiter was not being used internally by the renderers.
set_background_color was always set to true as there is no toggle for the renderer background color, instead users directly choose the color of their choice.
This setting is best referred to as a speed limit, as it involves the limits of all timing based aspects of the emulator, not only framerate.
This allows us to differentiate it from the fps unlocker setting.
GLASM is getting good enough that we can move it out of advanced
graphics settings. This removes the setting `use_assembly_shaders`,
opting for a enum class `shader_backend`. This comes with the benefits
that it is extensible for additional shader backends besides GLSL and
GLASM, and this will work better with a QComboBox.
Qt removes the related assembly shader setting from the Advanced
Graphics section and places it as a new QComboBox in the API Settings
group. This will replace the Vulkan device selector when OpenGL is
selected.
Additionally, mark all of the custom anisotropic filtering settings as
"WILL BREAK THINGS", as that is the case with a select few games.
Fixes Ori and the Blind Forest's menu on GLASM. For some reason
(probably high level optimizations) it is not sanitized on SPIR-V for
OpenGL. Vulkan is unaffected by this change.
Works around a bug where program parameters are only applied to the
current stage, and this one wasn't bound at the moment.
Affects all SSBO usages on GLASM.
This changes how Scheduler::Flush works. It queues the current command
buffer to be sent to the GPU but does not do it immediately. The Vulkan
worker thread takes care of that. Users will have to use
Scheduler::Flush + Scheduler::WaitWorker to get the previous behavior.
Scheduler::Finish is unchanged.
To avoid waiting on work never queued, Scheduler::Wait sends the current
command buffer if that's what the caller wants to wait.
Move code to separate files to be able to reuse it from OpenGL. This
greatly simplifies the pipeline cache logic on Vulkan.
Transform feedback state is not yet abstracted and it's still
intrusively stored inside vk_pipeline_cache. It will be moved when
needed on OpenGL.
Move descriptor lookup and update code to a separate thread. Delaying
this removes work from the main GPU thread and allows creating
descriptor layouts on another thread. This reduces a bit the workload
of the main thread when new pipelines are encountered.
Create multiple descriptor pools on demand. There are some degrees of
freedom what is considered a compatible pool to avoid wasting large
pools on small descriptors.
Mostly fixing unused *, implicit conversion, braced scalar init,
fpermissive, and some others.
Some Clang errors likely remain in video_core, and std::ranges is still
a pertinent issue in shader_recompiler

There's an optimization bug on non-git mesa versions where not
specifying GL_CLIENT_STORAGE_BIT causes very slow reads on the CPU
side.
Add this bit for all vendors.
On the texture cache we handle multisampled images by keeping their real
size in samples (e.g. 1920x1080 with 4 samples is 3840x2160).
This works nicely with size matches and other comparisons, but the
calculation for guest sizes was not having this in mind, and the size
was being multiplied (again) by the number of samples per dimension.
For example a 3840x2160 texture cache image had its width and height
multiplied by 2, resulting in a much larger texture.
Fix this issue.
- Fixes performance regression on cooking related titles when an
unrelated bug was fixed.
Images used as render targets were not being "prepared", causing
desynchronizations on the texture cache. Needs #6669 to avoid
performance regressions on certain cooking titles.
- Fixes black shadows on Age of Calamity.
Creates a new BasicSettings class in common/settings, and forces setting
a default and label for each setting that uses it in common/settings.
Moves defaults and labels from both frontends into common settings.
Creates a helper function in each frontend to facillitate reading the
settings now with the new default and label properties.
Settings::Setting is also now a subclass of Settings::BasicSetting. Also
adds documentation for both Setting and BasicSetting.
Fixes a regression unintentionally introduced by the garbage collector.
This makes regular memory downloads only flush the requested sizes.
This negatively affected Koei Tecmo games.
Removes common_sizes.h in favor of having `_KiB`, `_MiB`, `_GiB`, etc
user-literals within literals.h.
To keep the global namespace clean, users will have to use:
```
using namespace Common::Literals;
```
to access these literals.
There are a lot of scenarios where we don't particularly care whether or not the removal operation and just simply attempt a removal.
As such, removing the [[nodiscard]] attribute is best for these functions.
Use its std::stop_token to abort shader cache loading.
Using std::stop_token instead of std::atomic_bool allows the usage of
other utilities like std::stop_callback.
These changes should help in reducing crashes/drivers panics that may
occur due to synchronization issues between the shader completion and
later access of the decoded texture.
Per the spec, L1 is clamped to the value 0xff if it is greater than 0xff. An oversight caused us to take the maximum of L1 and 0xff, rather than the minimum.

Users may want to fall back to the CPU ASTC texture decoder due to hangs
and crashes that may be caused by keeping the GPU under compute heavy
loads for extended periods of time. This is especially the case in games
such as Astral Chain which make extensive use of ASTC textures.
yuzu requires CMake 3.15 yet find_program was using REQUIRED, which is
only available on 3.18 and later. Instead, we check for
"<VAR>-NOTFOUND".
In addition, check for additional requirements before building libusb or
FFmpeg with autotools. Otherwise, CMake configuration will pass yet
compilation will fail.
* Wrong alignment in u64 LOG_DEBUG -> memcpy.
* Huge shift exponent in stride calculation for linear buffer, unused result -> skipped.
* Large shift in buffer cache if word = 0, skip checking for set bits.
Non of those were critical, so this should not change any behavior.
At least with the assumption, that the last one used masking behavior, which always yield continuous_bits = 0.

The FPS counter was based on metrics in the nvdisp swapbuffers call. This metric would be accurate if the gpu thread/renderer were synchronous with the nvdisp service, but that's no longer the case.
This commit moves the frame counting responsibility onto the concrete renderers after their frame draw calls. Resulting in more meaningful metrics.
The displayed FPS is now made up of the average framerate between the previous and most recent update, in order to avoid distracting FPS counter updates when framerate is oscillating between close values.
The status bar update frequency was also changed from 2 seconds to 500ms.
Implements the OnClose method of the nvhost_vic device, and removes the remnants of an older implementation.
Also cleans up some of the surrounding code.
This line can only ever be reached if src is null, so dereferencing it

Instead, we dereference dst instead which is guaranteed to be valid.

Else the fence might get submited out-of-order into the queue, which makes testing them pointless.
Overhead should be tiny as the mutex is just moved from the queue to the writing code.
This was implicitly done by `is_powered_on = false`, however the explicit method allows us to block until the GPU is actually gone.
This should fix a race condition while removing the other subsystems while the GPU is still active.
It shall block until there is something to consume in the queue.
And use it for the GPU emulation instead of the spin loop.
This is only in booting the emulator, however in BOTW this is the case for about 1 second.

Currently, the Windows versions of the Intel OpenGL driver and the AMD
proprietary OpenGL driver do not properly support (or in fact degrade)
when asynchronous shader compilation is enabled. This blocks
specifically those drivers from using this feature. This affects
AMDGPU-PRO on Linux, and AMD's and Intel's OpenGL drivers on Windows.
ASTC texture decoding is currently handled by a CPU decoder for GPU's without native ASTC decoding support (most desktop GPUs). This is the cause for noticeable performance degradation in titles which use the format extensively.
This commit adds support to accelerate ASTC decoding using a compute shader on OpenGL for GPUs without native support.
In order to force the BGRA8 conversion on Nvidia using OpenGL, we need to forbid texture copies and views with other formats.
This commit also adds a boolean relating to this, as this needs to be done only for the OpenGL api, Vulkan must remain unchanged.
OpenGL does not natively support BGR internal formats, which causes many BGR textures to render incorrectly, with Red and Blue channels swapped.
This commit aims to address this by swizzling the blue and red channels on texture copies when a BGR format is encountered.
- Uses a fixed 64MB for the cache instead of an ever growing map.
- Slightly faster by using atomics instead of a single mutex for access.
- Thanks for Rodrigo for the idea.
Some games benefit from skipping caches (Pokémon Sword), and others
don't (Animal Crossing: New Horizons). Add an heuristic to decide this
at runtime.
The cache hit ratio has to be ~98% or better to not skip the cache.
There are 16 frames of buffer.
This commit removes early placeholders for an implementation of async nvdec. With recent changes to the source code, the placeholders are no longer accurate, and can cause a nullptr dereference due to the nature of the cdma_pusher lifetime.

This creates non-sRGB texture views for sRGB texture formats to allow for interfacing with these views in compute shaders using imageLoad and imageStore.

Load the current tick to a local variable, moving it out of an atomic
and allowing us to compare the value without going through a pointer
each time. This should make the loop more optimizable.
Fix a tragic off-by-one condition that causes Vulkan's stream buffer to
think it's always full, using fallback memory. The OpenGL was also
affected by this bug to a lesser extent.
We are already using robustness2 features without requiring it
explicitly, causing potential crashes on drivers without the extension.
Requiring this at boot allows better diagnostics for it and formalizes
our usage on the extension.
There was still a code path that could wait on a timeline semaphore tick
that would never be signalled.
While we are at it, make use of more STL algorithms.
Games can bind a null index buffer (size=0) where all indices are
evaluated as zero. VK_EXT_robustness2 doesn't support this and all
drivers segfault when a null index buffer is passed to
vkCmdBindIndexBuffer.
Workaround this by creating a 4 byte buffer and filling it with zeroes.
If it's read out of bounds, robustness takes care of returning zeroes as
indices.
Bind extra bytes beyond the guest API's bound range.
This is due to some games like Astral Chain operating out of bounds.
Binding the whole map range would be technically correct, but games
have large maps that make this approach unaffordable for now.
Avoids waiting idle while the GPU finishes to do work, and fixes an
issue where we'd wait forever if a single command buffer (logic tick)
all the data.
Detect when a memory region has been joined several times and increase
the size of the created buffer on those instances. The buffer is assumed
to be a "stream buffer", increasing its size should stop us from
constantly recreating it and fragmenting memory.
Ports from OpenGL the optimization to skip small 3D uniform buffer
uploads. This will take advantage of the previously introduced stream
buffer.
Fixes instances where the staging buffer offset was being ignored.
This uses a ring buffer similar to OpenGL's stream buffer for small
uploads. This stops us from allocating several small buffers, reducing
memory fragmentation and cache locality.
It uses dedicated allocations when possible.
Reimplement the buffer cache using cached bindings and page level
granularity for modification tracking. This also drops the usage of
shared pointers and virtual functions from the cache.
- Bindings are cached, allowing to skip work when the game changes few
bits between draws.
- OpenGL Assembly shaders no longer copy when a region has been modified
from the GPU to emulate constant buffers, instead GL_EXT_memory_object
is used to alias sub-buffers within the same allocation.
- OpenGL Assembly shaders stream constant buffer data using
glProgramBufferParametersIuivNV, from NV_parameter_buffer_object. In
theory this should save one hash table resolve inside the driver
compared to glBufferSubData.
- A new OpenGL stream buffer is implemented based on fences for drivers
that are not Nvidia's proprietary, due to their low performance on
partial glBufferSubData calls synchronized with 3D rendering (that
some games use a lot).
- Most optimizations are shared between APIs now, allowing Vulkan to
cache more bindings than before, skipping unnecesarry work.
This commit adds the necessary infrastructure to use Vulkan object from
OpenGL. Overall, it improves performance and fixes some bugs present on
the old cache. There are still some edge cases hit by some games that
harm performance on some vendors, this are planned to be fixed in later
commits.
Workaround an issue on Nvidia where creating a Vulkan instance from an
active OpenGL thread disables threaded optimization on the driver.
This optimization is important to have good performance on Nvidia
OpenGL.
Instead of using a two step initialization to report errors, initialize
the GPU renderer and rasterizer on the constructor and report errors
through std::runtime_error.
Some games usually write memory pages currently used by the GPU, causing
rendering issues (e.g. flashing geometry and shadows on Link's
Awakening). To workaround this issue, Guest CPU writes are delayed until
the command buffer finishes processing, but the pages are updated
immediately.
The overall behavior is:
- CPU writes are cached until they are flushed, they update the page
state, but don't change the modification state. Cached writes stop
pages from being flushed, in case games have meaningful data in it.
- Command processing writes (e.g. push constants) update the page state
and are marked to the command processor as dirty. They don't remove
the state of cached writes.
Also renames related CMake variables to match both the Find*FFmpeg* and
variables defined within the file. Fixes odd errors produced by the old
FindFFmpeg.
Citra's FindFFmpeg is slightly modified here: adds Citra's copyright at
the beginning, renames FFmpeg_INCLUDES to FFmpeg_INCLUDE_DIR, disables a
few components in _FFmpeg_ALL_COMPONENTS, and adds the missing avutil
component to the comment above.
For Linux, instructs CMake to use the FFmpeg submodule in externals.
This is HEAVILY based on our usage of the late Unicorn. Minimal change
to MSVC as it uses the yuzu-emu/ext-windows-bin. MinGW now targets the
same ext-windows-bin libraries as MSVC for FFmpeg. Adds FFMPEG_LIBRARIES
to WIN32 and simplifies video_core/CMakeLists.txt a bit.
Vulkan 1.0 didn't support creating sRGB image views on an ABGR8 VkImage
with storage usage bits. VK_KHR_maintenance2 addressed this allowing to
reduce the usage bits on a VkImageView.
To allow image store on non-sRGB image views when the VkImage is created
with sRGB, always create VkImages without sRGB and add the sRGB format
on the view.
The VertexA stage is not yet implemented, but Vulkan is adding its
descriptors, causing a discrepancy in the pushed descriptors and the
template. This generally ends up in a driver side crash.
Bypass the VertexA stage for now.
When we copy into a buffer, it might contain data modified from the GPU
on the same pages. Because of this, we have to flush the contents before
writing new data.
An alternative approach would be to write the data in place, but games
can also write data in other ways, invalidating our contents.
Fixes geometry in Zombie Panic in Wonderland DX.
Setting __GL_SHADER_DISK_CACHE_PATH we can force the cache directory to
be in yuzu's user directory to stop commonly distributed malware from
deleting our driver shader cache. And by setting
__GL_SHADER_DISK_CACHE_SKIP_CLEANUP we can have an unbounded shader
cache size.
This has only been implemented on Windows, mostly because previous tests
didn't seem to work on Linux.
Disable the precompiled cache on Nvidia's driver. There's no need to
hide information the driver already has in its own cache.
Silence the new validation layer error about SPIR-V not allowing OpUndef
on a OpTypeVoid, even when the SPIR-V spec doesn't say anything against
it.
They will be inserted as an undefined int to avoid SPIRV-Cross and
validation errors, but only when a debugging tool is attached.
Allow users of the allocator to hint memory usage for downloads. This
removes the non-descriptive boolean passed for "host visible" or not
host visible memory commits, and uses an enum to hint device local,
upload and download usages.
Fix a bug where the memory allocator could leave gaps between commits.
To fix this the allocation algorithm was reworked, although it's still
short in number of lines of code.
Rework the allocation API to self-contained movable objects instead of
naively using an unique_ptr to do the job for us. Remove the VK prefix.
Stops us from merging code with unused functions in the future.
If something is invoked behind conditionally evaluated code in
a way that the language can't see it (e.g. preprocessor macros), the
potentially unused function should use [[maybe_unused]].
It keeps track of the modified CPU and GPU ranges on a CPU page
granularity, notifying the given rasterizer about state changes
in the tracking behavior of the buffer.
Use a small vector optimization to store buffers smaller than 256 KiB
locally instead of using free store memory allocations.
With timeline semaphores we can avoid creating objects. Instead of
creating an event, grab the current tick from the scheduler and flush
the current command buffer. When the fence has to be queried/waited, we
can do so against the master semaphore instead of spinning on an event.
If Vulkan supported NVN like events or fences, we could signal from the
command buffer and wait for that without splitting things in two
separate command buffers.
Intel and AMD proprietary drivers are incapable of rendering to texture
views of different formats than the original texture. Avoid creating
these at a cache level. This will consume more memory, emulating them
with copies.
This breaks accelerated decoders trying to imageStore into images with
sRGB. The decoders are currently disabled so this won't cause issues at
runtime.
The "VK" prefix predates the "Vulkan" namespace. It was carried around
the codebase for consistency. "VKDevice" currently is a bad alias with
"VkDevice" (only an upcase character of difference) that can cause
confusion. Rename all instances of it.
For listing the available physical devices we can use Vulkan 1.0.
Now that MoltenVK supports 1.1 we can require it for running games.
Add missing documentation.
VKDevice::IsSuitable was not being called. To address this issue, check
suitability before initialization and throw an exception if it fails.
By doing this, we can deduplicate some code on queue searches.
Previosuly we would first search if a present and graphics queue
existed, then on initialization we would search again to find the index.
Report device enumeration errors with exceptions to be consistent with
other initialization related function calls. Reduces the amount of code
to maintain.
Move surface initialization code to a separate file. It's unlikely to
use this code outside of Vulkan, but keeping platform-specific code
(Win32, Xlib, Wayland) in its own translation unit keeps things cleaner.
Move more Vulkan code to report errors with exceptions and report them
through a log before notifying it with an error boolean for backwards
compatibility. In the future we can replace the rasterizer two-step
initialization to always use exceptions.
Initialize debug callbacks (messenger) from a separate file. This allows
sharing code with different backends.
Change our Vulkan error handling to use exceptions instead of error
codes, simplifying the initialization process.
The current texture cache has several points that hurt maintainability
and performance. It's easy to break unrelated parts of the cache
when doing minor changes. The cache can easily forget valuable
information about the cached textures by CPU writes or simply by its
normal usage.The current texture cache has several points that hurt

This commit aims to address those issues.
Without using VK_EXT_robustness2, we can't consider the 'enabled' (not
null) vertex buffers as dynamic state, as this leads to invalid Vulkan
state. Move this to static state that is always hashed and compared in
the pipeline key.
The bits for enabled vertex buffers are moved into the attribute state
bitfield. This is not 'correct' as it's not an attribute state, but that
struct has bits to spare, and it's used in an array of 32 elements (the
exact same number of vertex buffer bindings).
Most of the time people write code that always returns a value,
terminates execution, throws an exception, or uses an unconventional
jump primitive.
This is not always true when we build without asserts on mainline builds.
To avoid introducing undefined behavior on our most used builds, enforce
this warning signalling an error and stopping the build from shipping.
fmt now automatically prints the numeric value of an enum class member
by default, so we don't need to use casts any more.
Reduces the line noise a bit.
The previous definition was:
#define NUM(field_name) (sizeof(Maxwell3D::Regs::field_name) / sizeof(u32))
In cases where `field_name` happens to refer to an array, Clang thinks
`sizeof(an array value) / sizeof(a type)` is an instance of the idiom
where `sizeof` is used to compute an array length. So it thinks the
type in the denominator ought to be the array element type, and warns if
it isn't, assuming this is a mistake.
In reality, `NUM` is not used to get array lengths at all, so there is no
mistake. Silence the warning by applying Clang's suggested workaround
of parenthesizing the denominator.
On Apple platforms, FALSE and TRUE are defined as macros by
<mach/boolean.h>, which is included by various system headers.
Note that there appear to be no actual users of the names to fix up.
Migrates the video core code closer to enabling variable shadowing
warnings as errors.
This primarily sorts out shadowing occurrences within the Vulkan code.
This was only necessary for use with the
avcodec_decode_video2/avcoded_decode_audio4 APIs which are also
deprecated.
Given we use avcodec_send_packet/avcodec_receive_frame, this isn't
necessary, this is even indicated directly within the FFmpeg API changes
document here on 2017-09-26:
https://github.com/FFmpeg/FFmpeg/blob/master/doc/APIchanges#L410
This prevents our code from breaking whenever we update to a newer
version of FFmpeg in the future if they ever decide to fully remove this
API member.
Force early fragment tests when the 3D method is enabled.
The established pipeline cache takes care of recompiling if needed.
This is implemented only on Vulkan to avoid invalidating the shader
cache on OpenGL.
- Use .at() instead of raw indexing when dealing with untrusted indices.
- For the special case of WaitFence with syncpoint id UINT32_MAX,
instead of crashing, log an error and ignore. This is what I get when
running Super Mario Maker 2.
EmuWindow::PollEvents was called from the GPU thread (or the CPU thread
in sync-GPU mode) when swapping buffers. It had three implementations:
- In GRenderWindow, it didn't actually poll events, just set a flag and
emit a signal to indicate that a frame was displayed.
- In EmuWindow_SDL2_Hide, it did nothing.
- In EmuWindow_SDL2, it did call SDL_PollEvents, but this is wrong
because SDL_PollEvents is supposed to be called on the thread that set
up video - in this case, the main thread, which was sleeping in a
busyloop (regardless of whether sync-GPU was enabled). On macOS this
causes a crash.
To fix this:
- Rename EmuWindow::PollEvents to OnFrameDisplayed, and give it a
default implementation that does nothing.
- In EmuWindow_SDL2, do not override OnFrameDisplayed, but instead have
the main thread call SDL_WaitEvent in a loop.
This reduces the overhead of bounds checking on each element.
It won't reduce the cost of allocation because usually this vector's
capacity is usually large enough to hold whatever we push to it.
It's deprecated in the language to autogenerate these if the destructor
for a type is specified, so we can explicitly specify how we want these
to be generated.
The API of VP9 exposes a WasFrameHidden() function which accesses this
member. Given the constructor previously didn't initialize this member,
it's a potential vector for an uninitialized read.
Instead, we can initialize this to a deterministic value to prevent that
from occurring.
This implements texture cube arrays with shadow comparisons but doesn't
fix the asserts related to it.
Fixes out of bounds reads on swizzle constructors and makes them use
bounds checked ::at instead of the unsafe operator[].
This commit aims to implement the NVDEC (Nvidia Decoder) functionality, with video frame decoding being handled by the FFmpeg library.
The process begins with Ioctl commands being sent to the NVDEC and VIC (Video Image Composer) emulated devices. These allocate the necessary GPU buffers for the frame data, along with providing information on the incoming video data. A Submit command then signals the GPU to process and decode the frame data.
To decode the frame, the respective codec's header must be manually composed from the information provided by NVDEC, then sent with the raw frame data to the ffmpeg library.
Currently, H264 and VP9 are supported, with VP9 having some minor artifacting issues related mainly to the reference frame composition in its uncompressed header.
Async GPU is not properly implemented at the moment.

These compiler flags aren't shared with clang, so specifying these flags
unconditionally can lead to a bit of warning spam.
While we're in the area, we can also enable -Wunused-but-set-parameter
given this is almost always a bug.
This emulates the behavior we get on GLSL with regular SSBOs with a
pointer + length pair. It aims to be consistent with the crashes we
might get.
Out of bounds stores are ignored. Atomics are ignored and return zero.
Reads return zero.
Vulkan has requirements for primitive topologies that don't play nicely
with yuzu's. Since it's only 4 bits, we can move it to fixed state
without changing the size of the pipeline key.
- Fixes a regression on recent Nvidia drivers on Fire Emblem: Three
Houses.
RDNA devices seem to crash when using VK_EXT_extended_dynamic_state in
the latest 20.9.2 proprietary Windows drivers. As a workaround, for now
we block device names corresponding to current RDNA released products.
TMML takes an array argument that has no known meaning, this one appears
as the first component in gpr8 followed by s, t and r. Skip this
component when arrays are being used. Also implement CUBE texture types.
- Used by Pikmin 3: Deluxe Demo.
The old code had a sort function that was invalid and it didn't work as
expected when the base vector had a different order (e.g. renderdoc was
attached).
This sorts devices as expected and fixes a debug assert on MSVC.
The previous fix only partially solved the issue, as only certain GPUs that needed 9 or less MiB subtracted would work (i.e. GTX 980 Ti, GT 730). This takes from DXVK's example to divide `heap_size` by 2 to determine `allocable_size`. Additionally tested on my Quadro K4200, which previously required setting it to 12 to boot.
When HEADER_GENERATOR was included in the DEPENDS section of custom
commands, msbuild assumed this was always modified. Changing this file
is not common so we can remove it from there.
Allows some implementations to avoid completely zeroing out the internal
buffer of the optional, and instead only set the validity byte within
the structure.
This also makes it consistent how we return empty optionals.
This is a hack to destroy all HostCounter instances before the base
class destructor is called. The query cache should be redesigned to have
a proper ownership model instead of using shared pointers.
For now, destroy the host counter hierarchy from the derived class
destructor.
This reworks how host<->device synchronization works on the Vulkan
backend. Instead of "protecting" resources with a fence and signalling
these as free when the fence is known to be signalled by the host GPU,
use timeline semaphores.
Vulkan timeline semaphores allow use to work on a subset of D3D12
fences. As far as we are concerned, timeline semaphores are a value set
by the host or the device that can be waited by either of them.
Taking advantange of this, we can have a monolithically increasing
atomic value for each submission to the graphics queue. Instead of
protecting resources with a fence, we simply store the current logical
tick (the atomic value stored in CPU memory). When we want to know if a
resource is free, it can be compared to the current GPU tick.
This greatly simplifies resource management code and the free status of
resources should have less false negatives.
To workaround bugs in validation layers, when these are attached there's
a thread waiting for timeline semaphores.
Now that the GPU is initialized when video backends are initialized,
it's no longer needed to query components once the game is running: it
can be done when yuzu is booting.
This allows us to pass components between constructors and in the
process remove all Core::System references in the video backend.
'driver_id' can only be known on Vulkan 1.1 after creating a logical
device. Move the driver id check to disable
VK_EXT_extended_dynamic_state after the logical device is successfully
initialized.
The Vulkan device will have the extension enabled but it will not be
used.
I made a request on the Xbyak issue tracker to allow some constructors
to be constexpr in order to avoid static constructors from needing to
execute for some of our register constants.
This request was implemented, so this updates Xbyak so that we can make
use of it.
Vertex binding's <stride> is bugged on AMD's proprietary drivers when
using VK_EXT_extended_dynamic_state. Blacklist it for now while we
investigate how to report this issue to AMD.
Add the necessary CMake code to copy the contents in a string source
shader (GLSL or GLASM) to a header file then consumed by video_core
files.
This allows editting GLSL in its own files without having to maintain
them in source files.
For now, only OpenGL presentation shaders are moved, but we can add
GLASM presentation shaders and static SPIR-V generation through
glslangValidator in the future.
State track the current primitive topology with a regular comparison
instead of using dirty flags.
This fixes a bug in dirty flags for this particular state and it also
avoids unnecessary state changes as this property is stored in a
frequently changed bit field.
Migrates a remaining common file over to the Common namespace, making it
consistent with the rest of common files.
This also allows for high-traffic FS related code to alias the
filesystem function namespace as
namespace FS = Common::FS;
for more concise typing.
This was assigning the field to itself, which is a no-op. The size
doesn't change between its initial assignment and this one, so this is a
safe change to make.
Does not allocate more threads than available in the host system for boot-time shader compilation and always allocates at least 1 thread if hardware_concurrency() returns 0.
There were two issues with block linear copies. First the swizzling was
wrong and this commit reimplements them.
The other issue was that these copies are generally used to download
render targets from the GPU and yuzu was not downloading them from
host GPU memory unless the extreme GPU accuracy setting was selected.
This commit enables cached memory reads for all accuracy levels.
- Fixes level thumbnails in Super Mario Maker 2.
The puller register array is made up of u32s however the `NUM_REGS` value is the size in bytes, so switch it to avoid making the struct unnecessary large. Also fix a small typo in a comment.
We can make use of emplace()'s return value to determine whether or not
we need to perform an increment.
emplace() performs no insertion if an element already exist, so this can
eliminate a find() call.
NV_shader_buffer_{load,store} is a 2010 extension that allows GL applications
to use what in Vulkan is known as physical pointers, this is basically C
pointers. On GLASM these is exposed through the LOAD/STORE/ATOM
instructions.
Up until now, assembly shaders were using NV_shader_storage_buffer_object.
These work fine, but have a (probably unintended) limitation that forces
us to have the limit of a single stage for all shader stages. In contrast,
with NV_shader_buffer_{load,store} we can pass GPU addresses to the
shader through local parameters (GLASM equivalent uniform constants, or
push constants on Vulkan). Local parameters have the advantage of being
per stage, allowing us to generate code without worrying about binding
overlaps.
Given the expression involves a 32-bit value, this simplifies down to
just: 0x3ffffff. This is likely a remnant from testing that was never
cleaned up.
Resolves a -Wshift-overflow warning.
The purpose of make_pair is generally to deduce the types within the
pair without explicitly specifying the types, so these usages were
generally unnecessary, particularly when the type is enforced by the
array declaration.
Change GOB sizes from free-functions to constexpr constants.
Add SwizzleSliceToVoxel, a function that swizzles a 2D array of pixels
into a 3D texture and use it for 3D copies.
* Switch game settings to use a pointer
In order to add full per-game settings, we need to be able to tell yuzu to switch
to using either the global or game configuration. Using a pointer makes it easier
to switch.
* configuration: add new UI without changing existing funcitonality
The new UI also adds General, System, Graphics, Advanced Graphics,
and Audio tabs, but as yet they do nothing. This commit keeps yuzu
to the same functionality as originally branched.
* configuration: Rename files
These weren't included in the last commit. Now they are.
* configuration: setup global configuration checkbox
Global config checkbox now enables/disables the appropriate tabs in the game
properties dialog. The use global configuration setting is now saved to the
config, defaulting to true. This also addresses some changes requested in the PR.
* configuration: swap to per-game config memory for properties dialog
Does not set memory going in-game. Swaps to game values when opening the
properties dialog, then swaps back when closing it. Uses a `memcpy` to swap.
Also implements saving config files, limited to certain groups of configurations
so as to not risk setting unsafe configurations.
* configuration: change config interfaces to use config-specific pointers
When a game is booted, we need to be able to open the configuration dialogs
without changing the settings pointer in the game's emualtion. A new pointer
specific to just the configuration dialogs can be used to separate changes
to just those config dialogs without affecting the emulation.
* configuration: boot a game using per-game settings
Swaps values where needed to boot a game.
* configuration: user correct config during emulation
Creates a new pointer specifically for modifying the configuration while
emulation is in progress. Both the regular configuration dialog and the game
properties dialog now use the pointer Settings::config_values to focus edits to
the correct struct.
* settings: split Settings::values into two different structs
By splitting the settings into two mutually exclusive structs, it becomes easier,
as a developer, to determine how to use the Settings structs after per-game
configurations is merged. Other benefits include only duplicating the required
settings in memory.
* settings: move use_docked_mode to Controls group
`use_docked_mode` is set in the input settings and cannot be accessed from the
system settings. Grouping it with system settings causes it to be saved with
per-game settings, which may make transferring configs more difficult later on,
especially since docked mode cannot be set from within the game properties
dialog.
* configuration: Fix the other yuzu executables and a regression
In main.cpp, we have to get the title ID before the ROM is loaded, else the
renderer will reflect only the global settings and now the user's game specific
settings.
* settings: use a template to duplicate memory for each setting
Replaces the type of each variable in the Settings::Values struct with a new
class that allows basic data reading and writing. The new struct
Settings::Setting duplicates the data in memory and can manage global overrides
per each setting.
* configuration: correct add-ons config and swap settings when apropriate
Any add-ons interaction happens directly through the global values struct.
Swapping bewteen structs now also includes copying the necessary global configs
that cannot be changed nor saved in per-game settings. General and System config
menus now update based on whether it is viewing the global or per-game settings.
* settings: restore old values struct
No longer needed with the Settings::Setting class template.
* configuration: implement hierarchical game properties dialog
This sets the apropriate global or local data in each setting.
* clang format
* clang format take 2
can the docker container save this?
* address comments and style issues
* config: read and write settings with global awareness
Adds new functions to read and write settings while keeping the global state in
focus. Files now generated per-game are much smaller since often they only need
address the global state.
* settings: restore global state when necessary
Upon closing a game or the game properties dialog, we need to restore all global
settings to the original global state so that we can properly open the
configuration dialog or boot a different game.
* configuration: guard setting values incorrectly
This disables setting values while a game is running if the setting is
overwritten by a per game setting.
* config: don't write local settings in the global config
Simple guards to prevent writing the wrong settings in the wrong files.
* configuration: add comments, assume less, and clang format
No longer assumes that a disabled UI element means the global state is turned
off, instead opting to directly answer that question. Still however assumes a
game is running if it is in that state.
* configuration: fix a logic error
Should not be negated
* restore settings' global state regardless of accept/cancel
Fixes loading a properties dialog and causing the global config dialog to show
local settings.
* fix more logic errors
Fixed the frame limit would set the global setting from the game properties
dialog. Also strengthened the Settings::Setting member variables and simplified
the logic in config reading (ReadSettingGlobal).
* fix another logic error
In my efforts to guard RestoreGlobalState, I accidentally negated the IsPowered
condition.
* configure_audio: set toggle_stretched_audio to tristate
* fixed custom rtc and rng seed overwriting the global value
* clang format
* rebased
* clang format take 4
* address my own review
Basically revert unintended changes
* settings: literal instead of casting
"No need to cast, use 1U instead"
Thanks, Morph!

* Revert "settings: literal instead of casting
"
This reverts commit 95e992a87c898f3e882ffdb415bb0ef9f80f613f.
* main: fix status buttons reporting wrong settings after stop emulation
* settings: Log UseDockedMode in the Controls group
This should have happened when use_docked_mode was moved over to the controls group
internally. This just reflects this in the log.
* main: load settings if the file has a title id
In other words, don't exit if the loader has trouble getting a title id.
* use a zero
* settings: initalize resolution factor with constructor instead of casting
* Revert "settings: initalize resolution factor with constructor instead of casting"
This reverts commit 54c35ecb46a29953842614620f9b7de1aa9d5dc8.
* configure_graphics: guard device selector when Vulkan is global
Prevents the user from editing the device selector if Vulkan is the global
renderer backend. Also resets the vulkan_device variable when the users
switches back-and-forth between global and Vulkan.
* address reviewer concerns
Changes function variables to const wherever they don't need to be changed. Sets Settings::Setting to final as it should not be inherited from. Sets ConfigurationShared::use_global_text to static.

* main: load per-game settings after LoadROM
This prevents `Restart Emulation` from restoring the global settings *after* the per-game settings were applied. Thanks to BSoDGamingYT for finding this bug.
* Revert "main: load per-game settings after LoadROM"
This reverts commit 9d0d48c52d2dcf3bfb1806cc8fa7d5a271a8a804.
* main: only restore global settings when necessary
Loading the per-game settings cannot happen after the ROM is loaded, so we have to specify when to restore the global state. Again thanks to BSoD for finding the bug.
* configuration_shared: address reviewer concerns except operator overrides
Dropping operator override usage in next commit.
Co-Authored-By: LC <lioncash@users.noreply.github.com>
* settings: Drop operator overrides from Setting template
Requires using GetValue and SetValue explicitly. Also reverts a change that broke title ID formatting in the game properties dialog.
* complete rebase
* configuration_shared: translate "Use global configuration"
Uses ConfigurePerGame to do so, since its usage, at least as of now, corresponds with ConfigurationShared.
* configure_per_game: address reviewer concern
As far as I understand, it prevents the program from unnecessarily copying strings.

This fixes some cases where entries could have been removed multiple
times reading freed memory. To address this issue this commit removes
duplicates from entries marked for removal and sorts out the removal
process to fix another use-after-free situation.
Another issue fixed in this commit is orphan invalidation cache entries.
Previously only the entries that were invalidated in the current
operations had its entries removed. This led to more use-after-free
situations when these entries were actually invalidated but referenced
an object that didn't exist.
Like MirrorOnceBorder, this requires the GL_EXT_texture_mirror_clamp extension. This extension is unfortunately not available on Intel's drivers (both Windows proprietary and Linux Mesa). Use GL_MIRROR_CLAMP_TO_EDGE as a fallback if the extension is unavailable.
Macro code is just uploaded sequentially from a starting address, however that does not mean the entry point for the macro is at that address. This PR adds preliminary support for executing macros in the middle of our cached code.
This commit: Implements CPU Interrupts, Replaces Cycle Timing for Host
Timing, Reworks the Kernel's Scheduler, Introduce Idle State and
Suspended State, Recreates the bootmanager, Initializes Multicore
system.
This moves dynamic state present in VK_EXT_extended_dynamic_state to a
separate structure in FixedPipelineState. This is structure is at the
bottom allowing us to hash and memcmp only when the extension is not
supported.
Avoid illegal copies. This intercepts the last step of a copy to avoid
generating validation errors or corrupting the driver on some instances.
We can create views and emit copies accordingly in future commits and
remove this last-step validation.
Add a flat table to test if it's legal to create a texture view between
two formats or copy betweem them.
This table is based on ARB_copy_image and ARB_texture_view. Copies are
more permissive than views.
After marking buffers as resident, Nvidia's driver seems to take a
slow path. To workaround this issue, copy to a STREAM_READ buffer and
then call GetNamedBufferSubData on it.
This is a temporary solution until we have asynchronous flushing.
Making the stream buffer resident increases GPU usage significantly on
some games. This seems to be addressed invalidating the stream buffer
with InvalidateBufferData instead of using a Unmap + Map (with
invalidation flags).
