VkSparseImageMemoryRequirements

The VkSparseImageMemoryRequirements structure is defined as:

typedef struct VkSparseImageMemoryRequirements {
    VkSparseImageFormatProperties formatProperties;
    uint32_t imageMipTailFirstLod;
    VkDeviceSize imageMipTailSize;
    VkDeviceSize imageMipTailOffset;
    VkDeviceSize imageMipTailStride;
} VkSparseImageMemoryRequirements;

• formatProperties is a VkSparseImageFormatProperties structure specifying properties of the image format.
• imageMipTailFirstLod is the first mip level at which image subresources are included in the mip tail region.
• imageMipTailSize is the memory size (in bytes) of the mip tail region. If formatProperties.flags contains VK_SPARSE_IMAGE_FORMAT_SINGLE_MIPTAIL_BIT, this is the size of the whole mip tail, otherwise this is the size of the mip tail of a single array layer. This value is guaranteed to be a multiple of the sparse block size in bytes.
• imageMipTailOffset is the opaque memory offset used with VkSparseImageOpaqueMemoryBindInfo to bind the mip tail region(s).
• imageMipTailStride is the offset stride between each array-layer’s mip tail, if formatProperties.flags does not contain VK_SPARSE_IMAGE_FORMAT_SINGLE_MIPTAIL_BIT (otherwise the value is undefined:).
