# VkPhysicalDeviceMemoryDecompressionFeaturesNV(3) Manual Page

## Name

VkPhysicalDeviceMemoryDecompressionFeaturesNV - Structure describing if memory decompression is supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceMemoryDecompressionFeaturesNV` structure is defined as:

    // Provided by VK_NV_memory_decompression
    typedef struct VkPhysicalDeviceMemoryDecompressionFeaturesNV {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           memoryDecompression;
    } VkPhysicalDeviceMemoryDecompressionFeaturesNV;

## Members

This structure describes the following features:

## Description

- `sType` is the type of this structure.

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

- `memoryDecompression` indicates whether memory decompression is supported.

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

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceMemoryDecompressionFeaturesNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MEMORY_DECOMPRESSION_FEATURES_NV`

## See Also

VK_NV_memory_decompression, `VkBool32`, VkStructureType
