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.
Huge thanks to wwylele for finding this.

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.
- Fixes a hang on shutdown when NVFlinger thread is waiting on a syncpoint that will never occur.
- Commonly observed when stopping emulation in Super Mario Odyssey.

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
here is a logic bug that slipped through.
Instead, we dereference dst instead which is guaranteed to be valid.
Eliminates a potential bug vector related to inheritance. Plus, we
should generally be specifying the destructor as virtual within purely
virtual interfaces to begin with.
Amends implicit sign conversions occurring with usages of std::reduce
and also relocates it to its own utility function to reduce verbosity a
little bit.
When this was being made mandatory, these enablement of these features was removed, but this is still needed.
Fixes: 757fd1e917 ("vulkan_device: Require VK_EXT_robustness2")
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.
Avoid sending null pointer to memcpy as reported by Undefined Behaviour
Sanitizer. Replaces the std::memcpy calls in SpliceVectors with
std::copy calls. Opting to replace all the memcpy's with copy's.

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.
