Sparse Image Format Properties

typedef struct VkSparseImageFormatProperties { VkImageAspectFlags VkExtent3D VkSparseImageFormatFlags aspectMask; imageGranularity; flags; } VkSparseImageFormatProperties;

typedef enum VkSparseImageFormatFlagBits { VK_SPARSE_IMAGE_FORMAT_SINGLE_MIPTAIL_BIT = 0x00000001, VK_SPARSE_IMAGE_FORMAT_ALIGNED_MIP_SIZE_BIT = 0x00000002, VK_SPARSE_IMAGE_FORMAT_NONSTANDARD_BLOCK_SIZE_BIT = 0x00000004, } VkSparseImageFormatFlagBits;

void vkGetPhysicalDeviceSparseImageFormatProperties( VkPhysicalDevice VkFormat VkImageType VkSampleCountFlagBits VkImageUsageFlags VkImageTiling uint32_t* VkSparseImageFormatProperties* physicalDevice, format, type, samples, usage, tiling, pPropertyCount, pProperties);

void vkGetPhysicalDeviceSparseImageFormatProperties2( VkPhysicalDevice physicalDevice, const VkPhysicalDeviceSparseImageFormatInfo2* pFormatInfo, uint32_t* pPropertyCount, VkSparseImageFormatProperties2* pProperties);

Sparse Resource Creation

void vkGetImageSparseMemoryRequirements( VkDevice VkImage uint32_t* VkSparseImageMemoryRequirements* device, image, pSparseMemoryRequirementCount, pSparseMemoryRequirements);

void vkGetImageSparseMemoryRequirements2( VkDevice device, const VkImageSparseMemoryRequirementsInfo2* pInfo, uint32_t* pSparseMemoryRequirementCount, VkSparseImageMemoryRequirements2* pSparseMemoryRequirements);

void vkGetDeviceImageSparseMemoryRequirements( VkDevice const VkDeviceImageMemoryRequirements* uint32_t* VkSparseImageMemoryRequirements2* device, pInfo, pSparseMemoryRequirementCount, pSparseMemoryRequirements);
