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.
// Provided by VK_VERSION_1_0
void vkGetPhysicalDeviceSparseImageFormatProperties(
VkPhysicalDevice physicalDevice,
VkFormat format,
VkImageType type,
VkSampleCountFlagBits samples,
VkImageUsageFlags usage,
VkImageTiling tiling,
uint32_t* pPropertyCount,
VkSparseImageFormatProperties* pProperties);
Parameters
-
physicalDevice
is the physical device from which to query the sparse image format properties. -
format
is the image format. -
type
is the dimensionality of image. -
samples
is a VkSampleCountFlagBits value specifying the number of samples per texel. -
usage
is a bitmask describing the intended usage of the image. -
tiling
is the tiling arrangement of the texel blocks in memory. -
pPropertyCount
is a pointer to an integer related to the number of sparse format properties available or queried, as described below. -
pProperties
is eitherNULL
or 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
.
