Description

This extension provides versions of bindBufferMemory and bindImageMemory that allow multiple bindings to be performed at once, and are extensible.

This extension also introduces IMAGE_CREATE_ALIAS_BIT_KHR, which allows “identical” images that alias the same memory to interpret the contents consistently, even across image layout changes.

Promotion to Vulkan 1.1

All functionality in this extension is included in core Vulkan 1.1, with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.

New Commands

• bindBufferMemory2KHR

• bindImageMemory2KHR

New Structures

• BindBufferMemoryInfoKHR

• BindImageMemoryInfoKHR

New Enum Constants

• KHR_BIND_MEMORY_2_EXTENSION_NAME

• KHR_BIND_MEMORY_2_SPEC_VERSION

• Extending ImageCreateFlagBits:

  • IMAGE_CREATE_ALIAS_BIT_KHR

• Extending StructureType:

  • STRUCTURE_TYPE_BIND_BUFFER_MEMORY_INFO_KHR
  • STRUCTURE_TYPE_BIND_IMAGE_MEMORY_INFO_KHR

Version History

• Revision 1, 2017-05-19 (Tobias Hector)

  • Pulled bind memory functions into their own extension
