Description

This extension adds more expressive alignment requirements for uniform and storage texel buffers. Some implementations have single texel alignment requirements that cannot be expressed via VkPhysicalDeviceLimits::minTexelBufferOffsetAlignment.

New Structures

New Enum Constants

  • VK_EXT_TEXEL_BUFFER_ALIGNMENT_EXTENSION_NAME

  • VK_EXT_TEXEL_BUFFER_ALIGNMENT_SPEC_VERSION

  • Extending VkStructureType:

    • VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_TEXEL_BUFFER_ALIGNMENT_FEATURES_EXT

    • VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_TEXEL_BUFFER_ALIGNMENT_PROPERTIES_EXT

Promotion to Vulkan 1.3

Functionality in this extension is included in core Vulkan 1.3, with the EXT suffix omitted. However, only the properties structure is promoted. The feature structure is not promoted and texelBufferAlignment is enabled if using a Vulkan 1.3 instance. The original type name is still available as an alias of the core functionality.
