Fix VVL errors on coopvec tests (#8541)

jkwak-work · web-flow · commit f55f669d1bad · 2025-09-25T17:06:29.000Z
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
