2025-09-25	Fix VVL errors on coopvec tests (#8541)	Jay Kwak
	It appears that the inputType of the coopvec-mat-mul cannot be signed int32. It could be floating types or signed int32. Changing the tests to use uint32 instead of int32. The spec guarantees the following combinations and the rest should be queried at the runtime if it is supported by the HW. https://registry.khronos.org/vulkan/specs/latest/man/html/VkCooperativeVectorPropertiesNV.html#_description inputType \| inputInterpretation \| matrixInterpretation \| biasInterpretation \| resultType -- \| -- \| -- \| -- \| -- FLOAT16 \| FLOAT16 \| FLOAT16 \| FLOAT16 \| FLOAT16 UINT32 \| SINT8_PACKED \| SINT8 \| SINT32 \| SINT32 SINT8 \| SINT8 \| SINT8 \| SINT32 \| SINT32 FLOAT32 \| SINT8 \| SINT8 \| SINT32 \| SINT32 FLOAT16 \| FLOAT_E4M3 \| FLOAT_E4M3 \| FLOAT16 \| FLOAT16 FLOAT16 \| FLOAT_E5M2 \| FLOAT_E5M2 \| FLOAT16 \| FLOAT16

	Changes default for render-test to sm_6_5. Since sm_6_5 is the new default, remove the -use-dxil option, add -use-dxcb option Remove -use-dxil option from all test cases. Add -use-dxcb to two tests that needed it. Fixes #7611

2025-06-06	Disable coopvec while using Agility SDK and until graphics driver supports ↵	Jay Kwak
	it (#7357) * Disable coopvec tests until we have the driver support * Remove conflicting agility sdk binaries
2025-05-14	Support the new CoopVec builtins (#7108)	Jay Kwak
	**NOTE: This is a breaking change for users who were using POC variant of DXC. In order to keep the compatibility, the users will have to use -capability hlsl_coopvec_poc to their command line. This PR adds a new capability "hlsl_coopvec_poc". When it is used, the HLSL for CoopVec will be emitted for the POC variant of DXC. When it is not used, the HLSL for CoopVec will be emitted for the DXC that officially supports the cooperative vector.
2025-04-16	Skip cooperative vector tests when the graphics driver doesn't support it ↵	Jay Kwak
	(#6841) With this PR, cooperative-vector tests will run only when the hardware can support the feature. Unfortunately, DX12 backend will always reports that cooperative-vector is NOT supported until it is officially supported in May.
2025-04-02	Enable coopvec tests with dxc backend (#6726)	Jay Kwak
	This PR enables existing CoopVec tests with DX12 backend. In order to use the CoopVec feature with DX12 backend, we have to use an option, "-dx12-experimental", because the current implementation of CoopVec feature in dxcompiler.dll requires "experimental feature". Note that when the "experimental feature" is enabled, slang-test becomes less stable. For that reason, we should use the option "-dx12-experimental" only when it is needed. All tests for GLSL are deleted because CoopVec support for GLSL in Slang is deprecated and no longer supported. Some of CoopVec tests are still disabled for DX12 backend because: DXC doesn't support 8bit integer types and Some of CoopVec features are not implemented in DXC backend.
