Jon Leech b1042a3204 Change log for April 7, 2019 Vulkan 1.1.106 spec update:
* Update release number to 106.

Public Issues:

  * Add searchbox and generate search index for the chunked HTML target.
    Note that doing this requires several new toolchain components to build
    the `chunked` target (public issue 578 / internal issue 1352).
  * Remove descriptions of flink:vkCreateSampler sampler constraints which
    were repeated in the valid usage statements (public pull request 648).
  * Fix sense of conditional around a valid usage statement in the
    <<copies>> chapter (public issue 942).

Internal Issues:

  * Add missing pname:extent.width and pname:extent.height valid usage
    statements for flink:vkCmdClearAttachments (internal issue 1583).
  * Fix some inconsistencies in structures and corresponding pname:sType
    enumerant names by renaming
    sname:VkPhysicalDeviceShaderDrawParameterFeatures ->
    slink:slink:VkPhysicalDeviceShaderDrawParametersFeatures;
    sname:VkPhysicalDeviceVariablePointerFeatures ->
    slink:VkPhysicalDeviceVariablePointerFeatures;
    sname:VkPhysicalDeviceVariablePointerFeaturesKHR ->
    slink:VkPhysicalDeviceVariablePointerFeaturesKHR;
    sname:VkPhysicalDeviceBufferAddressFeaturesEXT ->
    slink:VkPhysicalDeviceBufferDeviceAddressFeaturesEXT;
    etext:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_DRAW_PARAMETER_FEATURES
    ->
    ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_DRAW_PARAMETERS_FEATURES;
    etext:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTER_FEATURES ->
    ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTERS_FEATURES;
    etext:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTER_FEATURES_KHR ->
    ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTERS_FEATURES_KHR;
    and etext:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_ADDRESS_FEATURES_EXT
    ->
    ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_DEVICE_ADDRESS_FEATURES_EXT.
    The old names are still available as aliases for backwards
    compatibility. This change required introducing valid XML markup which
    externally written XML processing scripts may need to be modified to
    accomodate, to support multiple aliases of a single command or token
    name (internal issue 1592).
  * Add slink:VkDevice as the first parameter to flink:vkSetLocalDimmingAMD
    (internal issue 1618).
  * Improve CI header compilation tests to test all Vulkan platform
    includes, using fake platform headers where needed, and change the
    `allchecks` Makefile target to use the more comprehensive
    `check_spec_links.py` script instead of the retired `checkinc` and
    `checklinks` targets.
  * Move descriptions of the ASTC compressed texture decode mode from the
    <<appendix-compressedtex-astc,appendix>> to the recently updated
    external Khronos Data Format Specification.
  * Fix minor markup and spelling issues in the `VK_NV_ray_tracing`
    extension.

= Vulkan^(R)^ API Documentation Project

This repository contains sources for the formal documentation of the Vulkan
API. This includes:

[options="compact"]
 * The Vulkan API Specification
 * Specification of Vulkan extensions
 * API reference ("`man`") pages
 * The XML API Registry (also mirrored at
   https://github.com/KhronosGroup/Vulkan-Headers)
 * Vulkan header files (also mirrored at
   https://github.com/KhronosGroup/Vulkan-Headers)
 * Related tools and scripts.

The authoritative public repository is located at
https://github.com/KhronosGroup/Vulkan-Docs/.
It hosts a public Issue tracker, and outside developers can file proposed
patches (Pull Requests) against the Specification, subject to approval
by Khronos.

If in doubt where to submit your Issue, consult the
https://github.com/KhronosGroup/Vulkan-Ecosystem repo.


== Branch Structure

Everything is now maintained in the `master` branch of the repository.
From this branch it is possible to generate both Vulkan 1.1 and Vulkan 1.0
Specifications, as well as specifications for any set of Extensions.


== Directory Structure

The directory structure is as follows:

```
README.adoc           This file
BUILD.adoc            Documents how to build the specifications, and man pages
COPYING.md            Copyright and licensing information
CODE_OF_CONDUCT.md    Code of Conduct
ChangeLog.txt         Change log summary for each public spec update
Makefile, make*       Makefile and helper build scripts (see BUILD.adoc)

man/                  Reference (man) pages for the API; mostly extracted from the spec source
out/                  Default directory for the generated documents
scripts/              Helper scripts used in specification, header, and reference page generation
style/                Sources for "styleguide" (Vulkan Documentation and Extensions: Procedures and Conventions)
xml/                  XML API Registry (vk.xml)
registry.txt          Sources for documentation of the vk.xml format
```


== Building the Specification and Reference Pages

The document sources are marked up in Asciidoctor format, and we use
`asciidoctor` and related toolchain components to generate output documents.
See link:BUILD.adoc[BUILD.adoc] for more information on installing the
toolchain and building the Specification.


== Generating Headers and Related Files

See link:xml/README.adoc[xml/README.adoc].

The header files (`include/vulkan/vulkan*.h`) and many parts of the
specification and reference page documents are generated from descriptions
in the XML API Registry (`xml/vk.xml`).
The generated files are not checked into the repository.
If you change `vk.xml`, you can regenerate the headers by going into
`xml/` and running:

    $ make clean install

The other generated files are built as required via dependencies in
the top-level `Makefile`.
