C Specification

The VkPhysicalDeviceMemoryDecompressionPropertiesNV structure is defined as:

// Provided by VK_NV_memory_decompression
typedef struct VkPhysicalDeviceMemoryDecompressionPropertiesNV {
    VkStructureType                       sType;
    void*                                 pNext;
    VkMemoryDecompressionMethodFlagsNV    decompressionMethods;
    uint64_t                              maxDecompressionIndirectCount;
} VkPhysicalDeviceMemoryDecompressionPropertiesNV;

Members

  • sType is the type of this structure.

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

  • decompressionMethods is a bitmask of VkMemoryDecompressionMethodFlagBitsNV specifying memory decompression methods supported by the implementation.

  • maxDecompressionIndirectCount specifies the maximum supported count value in the countBuffer of vkCmdDecompressMemoryIndirectCountNV

Description

If the VkPhysicalDeviceMemoryDecompressionPropertiesNV structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

  • VUID-VkPhysicalDeviceMemoryDecompressionPropertiesNV-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MEMORY_DECOMPRESSION_PROPERTIES_NV
