= Layers & Extensions (Informative)
|
|
|
|
Extensions to the Vulkan API can: be defined by authors, groups of authors,
|
|
and the Khronos Vulkan Working Group.
|
|
In order not to compromise the readability of the Vulkan Specification, the
|
|
core Specification does not incorporate most extensions.
|
|
The online Registry of extensions is available at URL
|
|
|
|
http://www.khronos.org/registry/vulkan/
|
|
|
|
and allows generating versions of the Specification incorporating different
|
|
extensions.
|
|
|
|
Most of the content previously in this appendix does not specify *use* of
|
|
specific Vulkan extensions and layers, but rather specifies the processes by
|
|
which extensions and layers are created.
|
|
As of version 1.0.21 of the Vulkan Specification, this content has been
|
|
migrated to the <<vulkan-styleguide, Vulkan Documentation and Extensions>>
|
|
document.
|
|
Authors creating extensions and layers must: follow the mandatory procedures
|
|
in that document.
|
|
|
|
The remainder of this appendix documents a set of extensions chosen when
|
|
this document was built.
|
|
Versions of the Specification published in the Registry include:
|
|
|
|
* Core API + mandatory extensions required of all Vulkan implementations.
|
|
* Core API + all registered and published Khronos (`KHR`) extensions.
|
|
* Core API + all registered and published extensions.
|
|
|
|
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.
|
|
|
|
[NOTE]

====
|
|
As of the initial Vulkan 1.1 public release, the `KHX` author ID is no
|
|
longer used.
|
|
All `KHX` extensions have been promoted to `KHR` status.
|
|
Previously, this author ID was used to indicate that an extension was
|
|
experimental, and is being considered for standardization in future `KHR` or
|
|
core Vulkan API versions.
|
|
We no longer use this mechanism for exposing experimental functionality.
|
|
|
|
Some vendors may use an alternate author ID ending in `X` for some of their
|
|
extensions.
|
|
The exact meaning of such an author ID is defined by each vendor, and may
|
|
not be equivalent to `KHX`, but it is likely to indicate a lesser degree of
|
|
interface stability than a non-`X` extension from the same vendor.
