Filtering of validation logs is now extended beyond BCn formats and now covers other format which have their feature set misreported by the driver, this significantly drives down the amount of logs depending on the title.
Implements an algorithm to determine formats that can be aliased as views without needing `VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT`, this avoids spamming warning logs on view creation when the aliased formats will function in practice.
The Khronos Validation Layer can often generate warning/error logs due to our intentional breakage from Vulkan specification, these can occur several times a frame resulting in the logs being spammed and making it difficult to extract useful information out of logs. The scope of these logs has now been reduced with more general filtering and the introduction of specialized filtering to handle complex cases such as BCn hacks with `libadrenotools` on Adreno devices.
Implements a cache for storing `VkFramebuffer` objects with a special path on devices with `VK_KHR_imageless_framebuffer` to allow for more cache hits due to an abstract image rather than a specific one.
Caching framebuffers is a fairly crucial optimization due to the cost of creating framebuffers on TBDRs since it involves calculating tiling memory allocations and in the case of Adreno's proprietary driver involves several kernel calls for mapping and allocating the corresponding framebuffer memory.
As we require a relaxed version of the Vulkan render pass compatibility clause for caching multi-subpass render passes, we now utilize a quirk to determine if this is supported which it is on Nvidia/Adreno while AMD/Mali where it isn't supported we force single-subpass render passes.
We found out that certain vendors such as Nvidia had a limitation on the global priority of a queue and requesting `VK_QUEUE_GLOBAL_PRIORITY_HIGH_EXT` would result in `VK_ERROR_NOT_PERMITTED_EXT`. A quirk has been introduced to supply the maximum supported global priority which is currently set on a per-vendor basis to avoid future crashes.
We can use inline push descriptors for writing to descriptor rather than allocating a descriptor set for a one time write and freeing it as this is rather inefficient while an inline push descriptor generally ends up being a direct `memcpy` on the driver side designed for this use-case.
We want Skyline to have the most favorable GPU scheduling possible due to low latency and high throughput requirements, we request high priority scheduling due to this reason.
Older Adreno proprietary drivers (5xx and below) will segfault while destroying the renderpass and associated objects if more than 64 subpasses are within a renderpass due to internal driver implementation details. This commit introduces checks to automatically break up a renderpass when that limit is hit.
Alised descriptor sets are incorrectly interpreted by the shader compiler causing it to bugger up LLVM function argument types and crash

Adreno GPUs have significant performance penalties from usage of `VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT` which require disabling UBWC and on Turnip, forces linear tiling. As a result, it's been made an optional quirk which doesn't supply the flag in `VkImageCreateInfo` and logs a warning if a view with a different Vulkan format from the original image is created.
We incorrectly determined an Adreno driver bug to require padding between binding slots but the real issue was not supporting consecutive binding writes for `VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER` and was fixed by the padding slot unintentionally requiring individual writes. The quirk has now been corrected to explicitly specify this as the bug and the solution is more apt.
Adreno proprietary drivers suffer from a bug where `VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER` requires 2 descriptor slots rather than one, we add a padding slot to fix this issue. `QuirkManager` was introduced to handle per-vendor/per-device errata and allow enabling this on Adreno proprietary drivers specifically as to not affect the performance of other devices.
Quirk terminology was deemed to be inappropriate for describing the features/extensions of a device. It has been replaced with traits which is far more fitting but quirks will be used as a terminology for errata in devices.
