## Name

VkPhysicalDeviceExtendedSparseAddressSpaceFeaturesNV - Structure describing feature to use extended sparse address space

Loading… please wait.

## C Specification

The `VkPhysicalDeviceExtendedSparseAddressSpaceFeaturesNV` structure is defined as:

    // Provided by VK_NV_extended_sparse_address_space
    typedef struct VkPhysicalDeviceExtendedSparseAddressSpaceFeaturesNV {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           extendedSparseAddressSpace;
    } VkPhysicalDeviceExtendedSparseAddressSpaceFeaturesNV;

## Members

This structure describes the following feature:

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

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

- `extendedSparseAddressSpace` indicates that the implementation supports allowing certain usages of sparse memory resources to exceed `VkPhysicalDeviceLimits`::`sparseAddressSpaceSize`. See VkPhysicalDeviceExtendedSparseAddressSpacePropertiesNV.

## Description

If the `VkPhysicalDeviceExtendedSparseAddressSpaceFeaturesNV` 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. `VkPhysicalDeviceExtendedSparseAddressSpaceFeaturesNV` can also be used in the `pNext` chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceExtendedSparseAddressSpaceFeaturesNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_EXTENDED_SPARSE_ADDRESS_SPACE_FEATURES_NV`
