# VkPhysicalDeviceCooperativeMatrixFeaturesNV(3) Manual Page

## Name

VkPhysicalDeviceCooperativeMatrixFeaturesNV - Structure describing cooperative matrix features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceCooperativeMatrixFeaturesNV` structure is defined as:

    typedef struct VkPhysicalDeviceCooperativeMatrixFeaturesNV {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           cooperativeMatrix;
        VkBool32           cooperativeMatrixRobustBufferAccess;
    } VkPhysicalDeviceCooperativeMatrixFeaturesNV;

## Members

The members of the `VkPhysicalDeviceCooperativeMatrixFeaturesNV` structure describe the following features:

## Description

- `cooperativeMatrix` indicates that the implementation supports the `CooperativeMatrixNV` SPIR-V capability.

- `cooperativeMatrixRobustBufferAccess` indicates that the implementation supports robust buffer access for SPIR-V `OpCooperativeMatrixLoadNV` and `OpCooperativeMatrixStoreNV` instructions.

If the `VkPhysicalDeviceCooperativeMatrixFeaturesNV` structure is included in the `pNext` chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether the feature is supported. `VkPhysicalDeviceCooperativeMatrixFeaturesNV` can also be included in the `pNext` chain of VkDeviceCreateInfo to enable features.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_COOPERATIVE_MATRIX_FEATURES_NV`
