## C Specification

The VkPhysicalDeviceTexelBufferAlignmentProperties structure is defined as:

// Provided by VK_VERSION_1_3
typedef struct VkPhysicalDeviceTexelBufferAlignmentProperties {
VkStructureType    sType;
void*              pNext;
VkDeviceSize       storageTexelBufferOffsetAlignmentBytes;
VkBool32           storageTexelBufferOffsetSingleTexelAlignment;
VkDeviceSize       uniformTexelBufferOffsetAlignmentBytes;
VkBool32           uniformTexelBufferOffsetSingleTexelAlignment;
} VkPhysicalDeviceTexelBufferAlignmentProperties;

or the equivalent

// Provided by VK_EXT_texel_buffer_alignment
typedef VkPhysicalDeviceTexelBufferAlignmentProperties VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT;

## Members

• sType is the type of this structure.

• pNext is NULL or a pointer to a structure extending this structure.

## Description

• 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.

• 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.

If the VkPhysicalDeviceTexelBufferAlignmentProperties 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.

Valid Usage (Implicit)
• VUID-VkPhysicalDeviceTexelBufferAlignmentProperties-sType-sType
sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_TEXEL_BUFFER_ALIGNMENT_PROPERTIES
