C Specification

The VkPhysicalDeviceMemoryDecompressionFeaturesEXT structure is defined as:

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

Members

This structure describes the following features:

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • memoryDecompression indicates whether memory decompression is supported.

Description

If the VkPhysicalDeviceMemoryDecompressionFeaturesEXT 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. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceMemoryDecompressionFeaturesEXT, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

  • VUID-VkPhysicalDeviceMemoryDecompressionFeaturesEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MEMORY_DECOMPRESSION_FEATURES_EXT
