Description

This extension adds a device feature for the SPIR-V CooperativeMatrixDecodeVectorNV capability and the SPV_NV_cooperative_matrix_decode_vector SPIR-V extension.

When enabled, shaders may use an optional decode vector operand with OpCooperativeMatrixLoadTensorNV (see that SPIR-V extension) to load multiple block-adjacent elements per decode callback invocation.

An implementation must also support VkPhysicalDeviceCooperativeMatrix2FeaturesNV::cooperativeMatrixBlockLoads when exposing this extension.
