C Specification

The VkSparseImageMemoryBind structure is defined as:

typedef struct VkSparseImageMemoryBind {
    VkImageSubresource         subresource;
    VkOffset3D                 offset;
    VkExtent3D                 extent;
    VkDeviceMemory             memory;
    VkDeviceSize               memoryOffset;
    VkSparseMemoryBindFlags    flags;
} VkSparseImageMemoryBind;

Members

  • subresource is the aspectMask and region of interest in the image.

  • offset are the coordinates of the first texel within the image subresource to bind.

  • extent is the size in texels of the region within the image subresource to bind. The extent must be a multiple of the sparse image block dimensions, except when binding sparse image blocks along the edge of an image subresource it can instead be such that any coordinate of offset + extent equals the corresponding dimensions of the image subresource.

  • memory is the VkDeviceMemory object that the sparse image blocks of the image are bound to. If memory is VK_NULL_HANDLE, the sparse image blocks are unbound.

  • memoryOffset is an offset into VkDeviceMemory object. If memory is VK_NULL_HANDLE, this value is ignored.

  • flags are sparse memory binding flags.

Description

Valid Usage
  • If the sparse aliased residency feature is not enabled, and if any other resources are bound to ranges of memory, the range of memory being bound must not overlap with those bound ranges

  • memory and memoryOffset must match the memory requirements of the calling command’s image, as described in section ../../html/vkspec.html#resources-association

  • subresource must be a valid image subresource for image (see ../../html/vkspec.html#resources-image-views)

  • offset.x must be a multiple of the sparse image block width (VkSparseImageFormatProperties::imageGranularity.width) of the image

  • extent.width must either be a multiple of the sparse image block width of the image, or else (extent.width + offset.x) must equal the width of the image subresource

  • offset.y must be a multiple of the sparse image block height (VkSparseImageFormatProperties::imageGranularity.height) of the image

  • extent.height must either be a multiple of the sparse image block height of the image, or else (extent.height + offset.y) must equal the height of the image subresource

  • offset.z must be a multiple of the sparse image block depth (VkSparseImageFormatProperties::imageGranularity.depth) of the image

  • extent.depth must either be a multiple of the sparse image block depth of the image, or else (extent.depth + offset.z) must equal the depth of the image subresource

Valid Usage (Implicit)
  • subresource must be a valid VkImageSubresource structure

  • If memory is not VK_NULL_HANDLE, memory must be a valid VkDeviceMemory handle

  • flags must be a valid combination of VkSparseMemoryBindFlagBits values
