C Specification
vkGetPhysicalDeviceSparseImageFormatProperties returns an array of
VkSparseImageFormatProperties.
Each element will describe properties for one set of image aspects that are
bound simultaneously in the image.
This is usually one element for each aspect in the image, but for
interleaved depth/stencil images there is only one element describing the
combined aspects.
void vkGetPhysicalDeviceSparseImageFormatProperties(
VkPhysicalDevice physicalDevice,
VkFormat format,
VkImageType type,
VkSampleCountFlagBits samples,
VkImageUsageFlags usage,
VkImageTiling tiling,
uint32_t* pPropertyCount,
VkSparseImageFormatProperties* pProperties);
Parameters
-
physicalDeviceis the physical device from which to query the sparse image capabilities. -
formatis the image format. -
typeis the dimensionality of image. -
samplesis the number of samples per texel as defined in VkSampleCountFlagBits. -
usageis a bitmask describing the intended usage of the image. -
tilingis the tiling arrangement of the texel blocks in memory. -
pPropertyCountis a pointer to an integer related to the number of sparse format properties available or queried, as described below. -
pPropertiesis eitherNULLor a pointer to an array of VkSparseImageFormatProperties structures.
Description
If pProperties is NULL, then the number of sparse format properties
available is returned in pPropertyCount.
Otherwise, pPropertyCount must point to a variable set by the user to
the number of elements in the pProperties array, and on return the
variable is overwritten with the number of structures actually written to
pProperties.
If pPropertyCount is less than the number of sparse format properties
available, at most pPropertyCount structures will be written.
If VK_IMAGE_CREATE_SPARSE_RESIDENCY_BIT is not supported for the given
arguments, pPropertyCount will be set to zero upon return, and no data
will be written to pProperties.
Multiple aspects are returned for depth/stencil images that are implemented
as separate planes by the implementation.
The depth and stencil data planes each have unique
VkSparseImageFormatProperties data.
Depth/stencil images with depth and stencil data interleaved into a single
plane will return a single VkSparseImageFormatProperties structure
with the aspectMask set to VK_IMAGE_ASPECT_DEPTH_BIT |
VK_IMAGE_ASPECT_STENCIL_BIT.
