C Specification
The VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT
structure is
defined as:
// Provided by VK_EXT_texel_buffer_alignment
typedef struct VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT {
VkStructureType sType;
void* pNext;
VkDeviceSize storageTexelBufferOffsetAlignmentBytes;
VkBool32 storageTexelBufferOffsetSingleTexelAlignment;
VkDeviceSize uniformTexelBufferOffsetAlignmentBytes;
VkBool32 uniformTexelBufferOffsetSingleTexelAlignment;
} VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
storageTexelBufferOffsetAlignmentBytes
is a byte alignment that is sufficient for a storage texel buffer of any format. The value must be a power of two. -
storageTexelBufferOffsetSingleTexelAlignment
indicates whether single texel alignment is sufficient for a storage texel buffer of any format. The value must be a power of two. -
uniformTexelBufferOffsetAlignmentBytes
is a byte alignment that is sufficient for a uniform texel buffer of any format. The value must be a power of two. -
uniformTexelBufferOffsetSingleTexelAlignment
indicates whether single texel alignment is sufficient for a uniform texel buffer of any format. The value must be a power of two.
Description
If the VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT
structure is included in the pNext
chain of the
VkPhysicalDeviceProperties2 structure passed to
vkGetPhysicalDeviceProperties2, it is filled in with each
corresponding implementation-dependent property.
If the single texel alignment property is VK_FALSE
, then the buffer
view’s offset must be aligned to the corresponding byte alignment value.
If the single texel alignment property is VK_TRUE
, then the buffer
view’s offset must be aligned to the lesser of the corresponding byte
alignment value or the size of a single texel, based on
VkBufferViewCreateInfo::format
.
If the size of a single texel is a multiple of three bytes, then the size of
a single component of the format is used instead.
These limits must not advertise a larger alignment than the
required maximum minimum value of
VkPhysicalDeviceLimits::minTexelBufferOffsetAlignment
, for any
format that supports use as a texel buffer.
