C Specification

Bits which can be set in VkDecompressMemoryRegionEXT::decompressionMethod or VkDecompressMemoryRegionNV::decompressionMethod specifying the decompression method to select, or returned in VkPhysicalDeviceMemoryDecompressionPropertiesEXT::decompressionMethods specifying the available decompression methods are:

// Provided by VK_EXT_memory_decompression
// Flag bits for VkMemoryDecompressionMethodFlagBitsEXT
typedef VkFlags64 VkMemoryDecompressionMethodFlagBitsEXT;
static const VkMemoryDecompressionMethodFlagBitsEXT VK_MEMORY_DECOMPRESSION_METHOD_GDEFLATE_1_0_BIT_EXT = 0x00000001ULL;
static const VkMemoryDecompressionMethodFlagBitsEXT VK_MEMORY_DECOMPRESSION_METHOD_GDEFLATE_1_0_BIT_NV = 0x00000001ULL;
// Provided by VK_NV_memory_decompression
// Equivalent to VkMemoryDecompressionMethodFlagBitsEXT
typedef VkMemoryDecompressionMethodFlagBitsEXT VkMemoryDecompressionMethodFlagBitsNV;

Description

  • VK_MEMORY_DECOMPRESSION_METHOD_GDEFLATE_1_0_BIT_EXT specifies that the GDeflate 1.0 algorithm is used to decompress data.
