Layers & Extensions (Informative)
Extensions to the Vulkan API can be defined by authors, groups of authors, and the Khronos Vulkan Working Group. The online Registry of extensions is available at URL
https://registry.khronos.org/vulkan/
Authors creating extensions and layers must follow the mandatory procedures described in the Vulkan Documentation and Extensions document when creating extensions and layers.
The version of the Vulkan specification published on the Vulkan Documentation site and in the Registry includes all registered and published extensions. It is also possible to build the specification with an arbitrary set of extensions included, and the specification you are viewing may not include all extensions.
In the remainder of this appendix, extensions are grouped as Khronos KHR,
multivendor EXT, and then alphabetically by author ID.
Within each group, extensions are listed in alphabetical order by their
name.
Extension Dependencies
Extensions which have dependencies on specific core versions or on other extensions will list such dependencies.
For core versions, the specified version must be supported at runtime. All extensions implicitly require support for Vulkan 1.0.
For a device extension, use of any device-level functionality defined by that extension requires that any extensions that extension depends on be enabled.
For any extension, use of any instance-level functionality defined by that extension requires only that any extensions that extension depends on be supported at runtime.
Extension Interactions
Some extensions define APIs which are only supported when other extensions
or core versions are supported at runtime.
Such interactions are noted as API Interactions.
