As an optional feature which can be enabled in the advanced graphics configuration, all pipelines that get built at the initial shader loading are stored in a VkPipelineCache object and are dumped to the disk.
These vendor specific pipeline cache files are located at `/shader/GAME_ID/vulkan_pipelines.bin`. This feature was mainly added because of an issue with the AMD driver (see yuzu-emu#8507) causing invalidation of the cache files the driver builds automatically.
This formats all copyright comments according to SPDX formatting guidelines.
Additionally, this resolves the remaining GPLv2 only licensed files by relicensing them to GPLv2.0-or-later.
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.
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.
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.
Migrates the video core code closer to enabling variable shadowing
warnings as errors.
This primarily sorts out shadowing occurrences within the Vulkan code.
Reduces some header churn and reduces rebuilds when some header
internals change.
While we're at it we can also resolve a missing include in buffer_cache.
