VkPhysicalDeviceTexelBufferAlignmentProperties(3)

# VkPhysicalDeviceTexelBufferAlignmentProperties(3) Manual Page

## Name

VkPhysicalDeviceTexelBufferAlignmentProperties - Structure describing the texel buffer alignment requirements supported by an implementation

## 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;

    // Provided by VK_EXT_texel_buffer_alignment
    // Equivalent to VkPhysicalDeviceTexelBufferAlignmentProperties
    typedef VkPhysicalDeviceTexelBufferAlignmentProperties VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT;

## Members

- `sType` is a VkStructureType value identifying 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
