Visual Studio has an option to search all files in a solution, so I
did a search in there for "default:" looking for any missing break
statements.
I've left out default statements that return something, and that throw
something, even if via ThrowInvalidType. UNREACHABLE leads towards throw
R_THROW macro leads towards a return

video_core: Modify astc texture decode error fill value
|
|
Given the issues with GPU accelerated ASTC decoding with NVIDIA's latest drivers, parallelize astc decoding on the CPU.
Uses half the available threads in the system for astc decoding.

vk_blit_screen: Fix non-accelerated texture size calculation

`via_header_index` is already checked above, so it would never be true in this branch

astc_decoder: Various performance and memory optimizations
|
|
This makes UnswizzleTexture up to two times faster. It is the main bottleneck in NVDEC video decoding.
|
|
This buffer was a list of EncodingData structures sorted by their bit length, with some duplication from the cpu decoder implementation.
We can take advantage of its sorted property to optimize its usage in the shader.
Thanks to wwylele for the optimization idea.

|
Moves leftover values that are no longer used by the gpu decoder back to the cpp implementation.
|
|
|
|
|
|
We can move them to instead be compile time constants within the shader.
|
|
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.

continue causes a memory leak in A Hat in Time.

This is not a real fix, so assert here and continue before crashing.

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.

AlignUpLog2 describes what the function does better than AlignBits.

Invalid ASTC textures seem to write more bytes here, increase
the size to something that can't make us push out of bounds.
|
|
Avoid out of bound reads on invalid ASTC textures.
Games can bind invalid textures that make us read or write out of bounds.

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

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.

Cleans out the rest of the occurrences of variable shadowing and makes

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.

maxwell_dma: Match official doc and support pitch->voxel copies

Normalizes pixel format names to match Vulkan names. Previous to this
commit pixel formats had no convention, leading to confusion and
potential bugs.
