C Specification

To enumerate additional supported cooperative matrix types and operations, call:

// Provided by VK_NV_cooperative_matrix2
VkResult vkGetPhysicalDeviceCooperativeMatrixFlexibleDimensionsPropertiesNV(
    VkPhysicalDevice                            physicalDevice,
    uint32_t*                                   pPropertyCount,
    VkCooperativeMatrixFlexibleDimensionsPropertiesNV* pProperties);

Parameters

  • physicalDevice is the physical device.

  • pPropertyCount is a pointer to an integer related to the number of cooperative matrix properties available or queried.

  • pProperties is either NULL or a pointer to an array of VkCooperativeMatrixFlexibleDimensionsPropertiesNV structures.

Description

If pProperties is NULL, then the number of flexible dimensions properties available is returned in pPropertyCount. Otherwise, pPropertyCount must point to a variable set by the application to the number of elements in the pProperties array, and on return the variable is overwritten with the number of structures actually written to pProperties. If pPropertyCount is less than the number flexible dimensions properties available, at most pPropertyCount structures will be written, and VK_INCOMPLETE will be returned instead of VK_SUCCESS, to indicate that not all the available flexible dimensions properties were returned.

If the cooperativeMatrixFlexibleDimensions feature is not supported, the implementation must advertise zero properties.

Valid Usage (Implicit)

  • VUID-vkGetPhysicalDeviceCooperativeMatrixFlexibleDimensionsPropertiesNV-physicalDevice-parameter
    physicalDevice must be a valid VkPhysicalDevice handle

  • VUID-vkGetPhysicalDeviceCooperativeMatrixFlexibleDimensionsPropertiesNV-pPropertyCount-parameter
    pPropertyCount must be a valid pointer to a uint32_t value

  • VUID-vkGetPhysicalDeviceCooperativeMatrixFlexibleDimensionsPropertiesNV-pProperties-parameter
    If the value referenced by pPropertyCount is not 0, and pProperties is not NULL, pProperties must be a valid pointer to an array of pPropertyCount VkCooperativeMatrixFlexibleDimensionsPropertiesNV structures

Return Codes
On success, this command returns

  • VK_INCOMPLETE

  • VK_SUCCESS

On failure, this command returns

  • VK_ERROR_OUT_OF_DEVICE_MEMORY

  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_UNKNOWN

  • VK_ERROR_VALIDATION_FAILED
