## Name

VkPhysicalDeviceCooperativeMatrixPropertiesKHR - Structure describing cooperative matrix properties supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceCooperativeMatrixPropertiesKHR` structure is defined as:

    // Provided by VK_KHR_cooperative_matrix
    typedef struct VkPhysicalDeviceCooperativeMatrixPropertiesKHR {
        VkStructureType       sType;
        void*                 pNext;
        VkShaderStageFlags    cooperativeMatrixSupportedStages;
    } VkPhysicalDeviceCooperativeMatrixPropertiesKHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `cooperativeMatrixSupportedStages` is a bitfield of VkShaderStageFlagBits describing the shader stages that cooperative matrix instructions are supported in. `cooperativeMatrixSupportedStages` will have the `VK_SHADER_STAGE_COMPUTE_BIT` bit set if any of the physical device’s queues support `VK_QUEUE_COMPUTE_BIT`.

## Description

`cooperativeMatrixSupportedStages` must not have any bits other than `VK_SHADER_STAGE_COMPUTE_BIT` set.

If the `VkPhysicalDeviceCooperativeMatrixPropertiesKHR` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceCooperativeMatrixPropertiesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_COOPERATIVE_MATRIX_PROPERTIES_KHR`
