Jon Leech 1ca0ea1ef0 Change log for July 22, 2016 Vulkan 1.0.22 spec update:
* Bump API patch number and header version number to 22 for this update.

Github Issues:

  * Translate the subpass self-dependency language into concrete
    validity statements, and added a validity statement about the
    restrictions on layout parameters (public issue 267).
  * Add validity requirement that
    slink:VkAttachmentDescription::pname:finalLayout and
    slink:VkAttachmentReference::pname:layout must not be
    ename:VK_IMAGE_LAYOUT_UNDEFINED or
    ename:VK_IMAGE_LAYOUT_PREINITIALIZED (public issue 268).
  * Clarify that slink:VkSubpassDescription::pname:pResolveAttachments
    layouts are used. Make language consistent with other attachment
    arrays (public issue 270).
  * Changed 64-bit definition for
    dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE to work for x32 platform in
    +vk.xml+ and the resulting +vulkan.h+ (public issue 282).
  * Add missing error return code for
    flink:vkEnumerateInstanceExtensionProperties and
    flink:vkEnumerateDeviceExtensionProperties (public issue 285)
  * Fix several cases of stext::VkStructName.memberName markup to
    stext::VkStructName::pname:memberName, to match other usage in the
    spec, and describe this markup in the style guide (public issue
    286).
  * Modified validity language generation script to avoid redundant
    common ancestor language if covered by generic parent language, and
    used `Both' instead of `Each' when appropriate (public issue 288).

Internal Issues:

  * Add language about behavior of flink:vkAllocateDescriptorSets when
    allocation fails due to fragmentation, a new error
    ename:VK_ERROR_FRAGMENTED_POOL, and a Note explaining the situation
    (internal issue 309).
  * For the features of code:PointSize, code:ClipDistance, and
    code:CullDistance, the SPIR-V capability is required to be declared
    on use (read or write) rather than on decoration (internal issue
    359).
  * Have desktop versions of GLSL respect precision qualification
    (code:mediump and code:lowp) when compiling for Vulkan. These will
    get translated to SPIR-V's code:RelaxedPrecision decoration as they
    do with OpenGL ES versions of GLSL (ESSL). The default precision of
    all types is code:highp when using a desktop version (internal issue
    360).
  * Add validity statement for slink:VkImageCreateInfo specifying that
    multisampled images must be two-dimensional, optimally tiled, and
    with a single mipmap level (internal issue 369).
  * Add validity statements to slink:VkImageViewCreateInfo disallowing
    creation of images or image views with no supported features. Made
    some slink:VkImageViewCreateInfo validity statements more precise
    and consistent. Added a Note to the <<features,features>> chapter
    about formats with no features (internal issue 371).
  * Remove +manpages+ from default build targets. Nroff outputs
    containing imbedded latexmath will not render properly. Fixing this
    is a lot of work for limited use cases (internal issue 401).

Other Commits:

  * Fix flink:vkRenderPassBeginInfo::pname:clearValueCount validity
    statement to be based on attachment indices rather than the number
    of cleared attachments
    (Vulkan-LoaderAndValidationLayers/issues/601).
  * Convert registry documentation from LaTeX to asciidoc source and
    rename from +src/spec/readme.tex+ to +src/spec/registry.txt+.
  * Fix lack of Oxford commas in validity language.
  * Lots of cleanup of generator scripts and Makefiles to move extension
    list for generator into the script arguments instead of the body of
    genvk.py, and express better dependencies between XML, scripts, and
    generated files.

Jon Leech e2d981c029 Change log for July 10, 2016 Vulkan 1.0.20 spec update:
* Bump API patch number and header version number to 20 for this
    update.

Github Issues:

  * Replaced existing reference pages by text automatically extracted
    from the specification source, or generated from vk.xml in some
    cases. This isn't a complete solution for the reference pages, but
    puts them in a much better state. The ref pages (only) are now
    placed under a CC BY open source license, which is more current than
    the obsolete license previously used.

    Further improvements to the pages should not edit them directly, but
    instead concentrate on the specification source from which the ref
    pages are being extracted (public issues 44, 55, 160; internal issue
    389).

Jon Leech 8c3c9b4c85 Change log for March 25, 2016 Vulkan 1.0.7 spec update:
* Bump API patch number and header version number to 7 for this
    update.

Github Issues:

  * Fix slink:VkSpecializationMapEntry example to avoid C/C++ strict
    aliasing issues (public issue 14).

  * Clarify the meaning of "matching" in flink:vkCmdBindDescriptorSets
    validity language (public issue 33).

  * Add stub reference pages so xrefs to not-yet-written pages don't
    generate 404 errors. However, the actual content of these pages
    still needs to be filled in as time allows (public issue 44, but
    does not close that issue out).

  * Remove incorrect validity statement for
    flink:vkGetImageSparseMemoryRequirements (public issue 85).

  * Reword the
    <<features-limits-bufferImageGranularity,bufferImageGranularity>>
    feature in terms of "aliasing", and clarify that it applies to
    bindings in the same memory object (public issue 90).

  * Clarify the relationship of the slink:VkPhysicalDeviceLimits
    pname:maxViewportDimensions and pname:viewportBoundsRange limits
    (public issue 92).

  * Specify sparse unbound texture replacement in the
    <<textures-texel-replacement,Texel Replacement>> section
    independently of robust buffer access language (public issue 100).

  * Add the <<fundamentals-architecture-model,Architecture Model>>
    section to explain architecture constraints Vulkan has chosen to
    accept in order to enable portable and performant code (public issue
    122).

  * State that an object must not be destroyed until *all* (not *any*)
    uses of that object have completed (public issue 123).

  * Minor editorial cleanup (public issues 129, 134, 146, 148).

  * Add validity language for layer and extension names to
    slink:VkDeviceCreateInfo matching that used for
    slink:VkInstanceCreateInfo (public issue 130).

  * Clean up terminology for the case when the bits set in one bitmask
    are a subset of the bits set in another bitmask (public issue 138).

  * Document that input attachments are UniformConstant not Input, in
    the <<interfaces-inputattachment,Fragment Input Attachment
    Interface>> section (public glslang bug 169).

Internal Issues:

  * Add max enum values to "flag bits" enums (internal issue ).

  * Clarify language around the various uses of the term "block" in the
    <<appendix-compressedtex-bc,Block Compressed Image Formats>> section
    (internal issue ).

  * Removed "expand" dependency from <enums> groups in vk.xml and added
    auto-generation code in the scripts to infer it instead, to ensure
    consistency. This caused renaming of sname:VkColorSpaceKHR and
    sname:VkPresentModeKHR etext:BEGIN_RANGE (etc.) tokens, but those
    tokens are metadata, not part of the API, and the Vulkan WG is OK
    with this change. This change adds ranges to two additional enums
    that were missing them due to not defining the "expand" attribute
    (internal issue 217).

  * Tweak makefile to generate ref page nroff (.3) files in the right
    output directory, working around an a2x limitation (internal issue
    223).

Other Commits:

  * Add validity requirements for flink:vkCmdCopyQueryPoolResults
    pname:dstBuffer parameter.

  * Fix ref page build to generate .3 targets in the right output
    directory.
