Description

Add runtime GPU offload tests for Texture2DMSArray. This is a multisampled arrayed 2D texture that only supports Load (with sample index), operator[], GetDimensions, and GetSamplePosition. It does not support Sample, Gather, CalculateLevelOfDetail, or mips.

Tasks

• Add Texture2DMSArray to offload-test-suite ResourceKind

  • offload-test-suite/include/Support/Pipeline.h — add Texture2DMSArray to ResourceKind enum, update all helper methods and ScalarEnumerationTraits
  • offload-test-suite/lib/API/VK/Device.cpp — add Texture2DMSArray cases: VkDescriptorType, VkImageViewType (VK_IMAGE_VIEW_TYPE_2D_ARRAY), image creation with VK_SAMPLE_COUNT_* and array layers
  • offload-test-suite/lib/API/DX/Device.cpp — add Texture2DMSArray cases: D3D12_SRV_DIMENSION_TEXTURE2DMSARRAY, SRV descriptor setup
  • offload-test-suite/lib/API/MTL/MTLDevice.cpp — add Texture2DMSArray case for Metal texture type mapping (MTLTextureType2DMultisampleArray)

• Write tests (offload-test-suite/test/Feature/Textures/)

  • Texture2DMSArray.Load.test.yaml — Load(int3, int) and Load(int3, int, int2) with different sample indices and array slices
  • Texture2DMSArray.OperatorIndex.test.yaml — Tex[int3] subscript across array slices
  • Texture2DMSArray.sample.OperatorIndex.test.yaml — sample[int][int3] with different sample indices and array slices
