C Specification

The VkPhysicalDeviceCooperativeMatrixFeaturesKHR structure is defined as:

// Provided by VK_KHR_cooperative_matrix
typedef struct VkPhysicalDeviceCooperativeMatrixFeaturesKHR {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           cooperativeMatrix;
    VkBool32           cooperativeMatrixRobustBufferAccess;
} VkPhysicalDeviceCooperativeMatrixFeaturesKHR;

Members

This structure describes the following features:

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • cooperativeMatrix indicates that the implementation supports the CooperativeMatrixKHR SPIR-V capability.

  • cooperativeMatrixRobustBufferAccess indicates that the implementation supports robust buffer access for SPIR-V OpCooperativeMatrixLoadKHR and OpCooperativeMatrixStoreKHR instructions.

Description

If the VkPhysicalDeviceCooperativeMatrixFeaturesKHR structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceCooperativeMatrixFeaturesKHR, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceCooperativeMatrixFeaturesKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_COOPERATIVE_MATRIX_FEATURES_KHR
