VkDecompressMemoryRegionNV
The VkDecompressMemoryRegionNV
structure is defined as:
typedef struct VkDecompressMemoryRegionNV {
VkDeviceAddress srcAddress;
VkDeviceAddress dstAddress;
VkDeviceSize compressedSize;
VkDeviceSize decompressedSize;
VkMemoryDecompressionMethodFlagsNV decompressionMethod;
} VkDecompressMemoryRegionNV;
srcAddress
is the address where compressed data is stored.dstAddress
is the destination address where decompressed data will be written.compressedSize
is the size of compressed data in bytes.decompressedSize
is the size of decompressed data in bytes.decompressionMethod
is a bitmask ofVkMemoryDecompressionMethodFlagBitsNV
with a single bit set specifying the method used to decompress data.
Valid Usage
VUID-VkDecompressMemoryRegionNV-srcAddress-07685
The srcAddress
must be 4 byte aligned
VUID-VkDecompressMemoryRegionNV-srcAddress-07686
The memory in range srcAddress
and srcAddress
+
compressedSize
must be valid and bound to a VkDeviceMemory
object
VUID-VkDecompressMemoryRegionNV-dstAddress-07687
The dstAddress
must be 4 byte aligned
VUID-VkDecompressMemoryRegionNV-decompressionMethod-09395
If decompressionMethod
is
VK_MEMORY_DECOMPRESSION_METHOD_GDEFLATE_1_0_BIT_NV
, then
decompressedSize
must be less than or equal to 65536 bytes
VUID-VkDecompressMemoryRegionNV-dstAddress-07688
The memory in range dstAddress
and dstAddress
+
decompressedSize
must be valid and bound to a
VkDeviceMemory
object
VUID-VkDecompressMemoryRegionNV-decompressedSize-07689
The decompressedSize
must be large enough to hold the
decompressed data based on the decompressionMethod
VUID-VkDecompressMemoryRegionNV-decompressionMethod-07690
The decompressionMethod
must have a single bit set
VUID-VkDecompressMemoryRegionNV-srcAddress-07691
The srcAddress
to srcAddress
+ compressedSize
region must not overlap with the dstAddress
and dstAddress
+ decompressedSize
region
Valid Usage (Implicit)
VUID-VkDecompressMemoryRegionNV-decompressionMethod-parameter
decompressionMethod
must be a valid combination of VkMemoryDecompressionMethodFlagBitsNV values
VUID-VkDecompressMemoryRegionNV-decompressionMethod-requiredbitmask
decompressionMethod
must not be 0
