C Specification

The VkCooperativeMatrixProperties2EXT structure is defined as:

// Provided by VK_EXT_cooperative_matrix_maintenance1
typedef struct VkCooperativeMatrixProperties2EXT {
    VkStructureType       sType;
    void*                 pNext;
    uint32_t              MGranularity;
    uint32_t              NGranularity;
    uint32_t              KGranularity;
    VkComponentTypeKHR    AType;
    VkComponentTypeKHR    BType;
    VkComponentTypeKHR    CType;
    VkComponentTypeKHR    ResultType;
} VkCooperativeMatrixProperties2EXT;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • MGranularity is the granularity of the number of rows in matrices A, C, and Result. The rows must be an integer multiple of this value.

  • KGranularity is the granularity of columns in matrix A and rows in matrix B. The columns/rows must be an integer multiple of this value.

  • NGranularity is the granularity of columns in matrices B, C, Result. The columns must be an integer multiple of this value.

  • AType is the component type of matrix A, of type VkComponentTypeKHR.

  • BType is the component type of matrix B, of type VkComponentTypeKHR.

  • CType is the component type of matrix C, of type VkComponentTypeKHR.

  • ResultType is the component type of matrix Result, of type VkComponentTypeKHR.

Description

If some types are preferred over other types (e.g. for performance), they should appear earlier in the list enumerated by vkGetPhysicalDeviceCooperativeMatrixProperties2EXT.

At least one entry in the list must have power of two values for all of MGranularity, KGranularity, and NGranularity.
