Module: vkd3d Branch: master Commit: 1b11b57652b3c2cd785353c8ccd29d5f87b0993a URL: https://gitlab.winehq.org/wine/vkd3d/-/commit/1b11b57652b3c2cd785353c8ccd29d...

vkd3d-shader: Introduce DESCRIPTOR_INFO_FLAG_UAV_ATOMICS and always declare UAV images with known type for atomic ops.
Atomic ops on images with Unknown type will cause SPIR-V validation failure, and assertion failure in Mesa debug builds. D3D12 allows atomics on typed buffers, and this requires a distinction to be made between UAV reads and atomic ops.
