ce60b9c887 Change log for March 7, 2018 Vulkan 1.1.70 spec update:
* Vulkan 1.1 initial release. Bump API patch number and header version
    number to 70 for this update. The patch number will be used for both
    Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment
    continuously from the previous Vulkan 1.0.69 update.

    NOTE: We are not publishing an updated 1.0.70 specification, or 1.1
    reference pages, along with 1.1.70. There are still minor issues to work
    out with those build targets. However, we will soon generate all three
    types of documents as part of the regular spec update cycle.

    NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the
    current specification in the `master` branch. The `1.0` branch is out of
    date and will not be maintained, since we will be generating both 1.1
    and 1.0 specifications from the `master` branch in the future.

Github Issues:

  * Clarify how mapped memory ranges are flushed in
    flink:vkFlushMappedMemoryRanges (public issue 127).
  * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a
    list of tasks that each command performs, rather than necessarily being
    discrete pieces of hardware that one task flows through. Add a
    "`synchronization command`" pipeline type which all synchronization
    command execute (it's just TOP + BOTTOM), with an explanatory note
    (public issue 554).

Internal Issues:

  * Regenerate all images used in the spec in Inkscape with a consistent
    look-and-feel, and adjust image size attributes so they're all legible,
    and not too large with respect to the spec body text (internal issue
    701).
  * Document in the <<extensions,extensions>> appendix and in the style
    guide that `KHX` extensions are no longer supported or used in the
    Vulkan 1.1 timeframe (internal issue 714).
  * Remove the leftover equations_temp directory after PDF build completes
    (internal issue 925).
  * Update the <<credits, Credits (Informative)>> appendix to include
    contributors to Vulkan 1.1, and to list them according to the API
    version(s) they contributed to (internal issue 987).
  * Add a NOTE to the introduction explaining that interfaces defined by
    extensions which were promoted to Vulkan 1.1 are now expressed as
    aliases of the Vulkan 1.1 type (internal issue 991).
  * Instrument spec source conditionals so spec can be built with 1.1
    features, extensions promoted to 1.1, or both (internal issues 992,
    998).
  * Modify the XML schema and tools to support explicit aliasing of types,
    structures, and commands, and use this to express the promotion of 1.0
    extensions to 1.1 core features, by making the extension interfaces
    aliases of the core features they were promoted to. Mark up promoted
    interfaces to allow still generating 1.0 + extension specifications
    (internal issue 991).
  * Platform names, along with corresponding preprocessor symbols to enable
    extensions specific to those platforms, are now reserved in vk.xml using
    the <platform> tag. Update the registry schema and schema specification
    to match (internal issue 1011).
  * Updated the <<textures-texel-replacement, Texel Replacement>> section to
    clarify that reads from invalid texels for image resources result in
    undefined values (internal issue 1014).
  * Modify description of patch version so it continues to increment across
    minor version changes (internal issue 1033).
  * Clarify and unify language describing physical device-level core and
    extension functionality in the <<fundamentals-validusage-extensions,
    Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid
    Usage for Newer Core Versions>>, <<initialization-functionpointers
    Command Function Pointers>>, <<initialization-phys-dev-extensions,
    Extending Physical Device From Device Extensions>>
    <<extended-functionality-instance-extensions-and-devices, Instance
    Extensions and Device Extensions>> sections and for
    flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that
    instance-level functionality is tied to the loader, and independent of
    the ICD; physical device-level functionality is tied to the ICD, and
    associated with device extensions; physical devices are treated more
    uniformly between core and extensions; and instance and physical
    versions can be different (internal issue 1048).
  * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>>
    section to clarify the ability for pending command buffers to transition
    to the invalid state after submission, and add a command buffer
    lifecycle diagram (internal issue 1050).
  * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters
    are ignored when push descriptors are not supported (internal issue
    1054).
  * Specify that flink:vkCreateImage will return an error if the image is
    too large, in a NOTE in the slink:VkImageFormatProperties description
    (internal issue 1078).
  * Remove near-duplicate NOTEs about when to query function pointers
    dynamically in the <<initialization, Initialization>> chapter and
    replace by extending the NOTE in the <<fundamentals-abi, Application
    Binary Interface>> section (internal issue 1085).
  * Restore missing references to "`Sparse Resource Features`" in the
    flink:VkBufferCreateFlagBits description (internal issue 1086).
  * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl`
    specification, the <<descriptorsets, Resource Descriptors>> section and
    its subsections, and the <<interfaces-resources-descset, Descriptor Set
    Interface>> for consistency, reduction of duplicate information, and
    removal of GLSL correspondance/examples (internal issue 1090).
  * Correctly describe code:PrimitiveId as an Input for tessellation control
    and evaluation shaders, not an Output (internal issue 1109).
  * Relax the requirements on chroma offsets for nearest filtering in
    <<textures-implict-reconstruction, Implicit Reconstruction>> (internal
    issue 1116).

Other Issues:

  * Clarify the intended relationship between specification language and
    certain terms defined in the Khronos Intellectual Property Rights
    policy. Specific changes include:
  ** Rewrote IP/Copyright preamble and introduction to better agree with
     normative language both as laid out in the introduction, and the
     Khronos IPR policy.
  ** Added notion of fully informative sections, which are now tagged with
     "`(Informative)`" in their titles.
  ** Removed non-normative uses of the phrase "`not required`"
  ** Clarified the distinction between terms "`optional`" and "`not
     required:`" as they relate to the IPR Policy, and updated specification
     text to use terms consistent with the intent.
  ** Reduced additions to RFC 2119, and ensured the specification agreed
     with the leaner language.
  ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from
     normative text.
  ** Moved several paragraphs that should not have been normative to
     informative notes.
  ** Clarified a number of definitions in the Glossary.
  ** Updated the document writing guide to match new terminology changes.
  * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire,
    application memory lifetime>> language that that for objects other than
    descriptor sets, a slink:VkDescriptorSetLayout object used in the
    creation of another object (such as slink:VkPipelineLayout or
    slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation
    of that object and can be safely destroyed afterwards.
  * Updated the <<textures-scale-factor, Scale Factor Operation>> section to
    use the ratio of anisotropy, rather than the integer sample rate, to
    perform the LOD calculation. The spec still allows use of the sample
    rate as the value used to calculate the LOD, but no longer requires it.
  * Update `vulkan_ext.c` to include all platform-related definitions from
    the Vulkan platform headers, following the split of the headers into
    platform-specific and non-platform-specific files.
  * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter
    which accidentally duplicated an anchor in the pipelines chapter. There
    were no reference to this anchor, fortunately.
  * Add valid usage statement for slink:VkWriteDescriptorSet and
    slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout
    used to allocate the source and destination sets must not have been
    destroyed at the time flink:vkUpdateDescriptorSets is called.
  * Document mapping of subgroup barrier functions to SPIR-V, and clarify a
    place where subgroupBarrier sounds like it's execution-only in the
    standalone `GL_KHR_shader_subgroup` specification.
  * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with
    the default Arial font family replaced by the sans-serif Noto font
    family.
  * Numerous minor updates to README.adoc, build scripts, Makefiles, and
    registry and style guide specifications to support Vulkan 1.1 outputs,
    use them as defaults, and remove mention of `KHX` extensions, which are
    no longer supported.

New Extensions:

  * `VK_EXT_vertex_attrib_divisor`

b9e9296cd8 Change log for June 24, 2017 Vulkan 1.0.53 spec update:
* Bump API patch number and header version number to 53 for this update.

Github Issues:

Internal Issues:

  * Clarify mappings of coordinates for mutable, compatible image views in
    slink:VkImageViewCreateInfo (internal issue 815).
  * Make ename:VK_BIND_SFR_BIT require a logical device with multiple
    physical devices, so that standard sparse image block dimensions are
    only required on systems that support multi-GPU (internal issue 835).
  * Convert all files from use of // refBegin .. // refEnd comments to
    delimit ref pages, to use of open blocks, and update style guide
    accordingly (internal issue 839).
  * Add valid usage for slink:VkWriteDescriptorSet when performing updates
    to a ename:VK_STORAGE_IMAGE descriptor with layout
    ename:VK_IMAGE_LAYOUT_GENERAL.
  * Add a hack to the validity generator script to support an odd
    interaction between flink:vkCmdFillBuffer and an extension (internal
    issue 853).
  * Remove redundant text describing slink:VkBufferCreateInfo::pname:usage,
    which was already covered by implicit valid usage (internal issue 854).
  * Update implicit validity generator script to properly handle the
    pname:sType and pname:pNext members of "returnedonly" structures
    (internal issue 874).
  * Note that slink:VkApplicationInfo::pname:pApplicationName &
    slink:VkApplicationInfo::pname:pEngineName are optional, and add missing
    implicit valid usage statements for flink:vkDestroyInstance.
  * Added missing valid usage for flink:vkCmdWriteTimestamp to require a
    timestamp query pool.
  * Simplify and/or split "`non-atomic`" valid usage statements.

New Extensions:

  * `VK_AMD_gpu_shader_int16`
  * `VK_EXT_blend_operation_advanced`
  * `VK_EXT_sampler_filter_minmax`
  * `VK_NV_framebuffer_mixed_samples`

-----------------------------------------------------
Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release
combines both change sets.
-----------------------------------------------------

Change log for June 13, 2017 Vulkan 1.0.52 spec update:

  * Bump API patch number and header version number to 52 for this update.

Github Issues:

Internal Issues:

  * Clarify behavior when non-coherent memory has
    <<memory-device-unmap-does-not-flush, not been flushed before being
    unmapped>> (internal issue 819).
  * Fix description of code:WorkgroupSize builtin to note it decorates an
    object, not a variable (internal issue 836).
  * Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style
    equations are rendered properly (internal issue 845).
  * Add language to the "`Extension Handles, Objects, Enums, and Typedefs`"
    section of the Procedures and Conventions document stating that any new
    handle type requires a corresponding entry in the elink:VkObjectType
    enumerated type (internal issue 856).
  * Update style guide to use slink macro for Vulkan handle type names, and
    define narrow conditions under which to use the *name and *text macros
    instead of *link (internal issue 886).
  * Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>>
    extension on VK_KHX_device_group_creation to +vk.xml+ and the extension
    appendix.
  * Change the copyright on Vulkan specification asciidoc *source* files to
    CC-BY 4.0, and update the proprietary Khronos copyright applied to the
    generated *output* formats (internal issue 327). This enables broader
    re-use and modification of the Vulkan specification sources, while not
    affecting the Reciprocal IP License between Vulkan Adopters and Working
    Group Members.

New Extensions:

  * `VK_NV_fill_rectangle`
  * `VK_NV_fragment_coverage_to_color`

685295031d Change log for May 12, 2017 Vulkan 1.0.49 spec update:
* Bump API patch number and header version number to 49 for this update.

Github Issues:

  * Modify reference page extraction script to make internal links to spec
    anchors refer to the core specification instead of being dangling links
    (public issue 455).
  * Fix GL_KHR_vulkan_glsl typo and add a nor-normative mapping to the newly
    published StorageBuffer class (public issue 466).
  * Both flink:vkEnumerateInstanceExtensionProperties and
    flink:vkEnumerateDeviceExtensionProperties return
    ename:VK_ERROR_LAYER_NOT_PRESENT, which covers the error case of an
    application providing a layer name that wasn't returned by
    ftext:vkEnumerate{Instance|Device}LayerProperties (public issue 487).
  * The specification for flink:VkApplicationInfo::apiVersion says that the
    driver must return ename:VK_ERROR_INCOMPATIBLE_DRIVER in the case that
    pname:apiVersion specifies a non-supported version. That means that the
    valid usage should not also state that, and so the VU statement is
    removed. The VU had language about "`an effective substitute`" that
    would have been lost, and so it was moved to the pname:apiVersion
    description (public issue 488).

Internal Issues:

  * Modify implicit validity generator script to assign asciidoc anchors to
    all valid usage statements it generates, and reflow.py script to insert
    Valid Usage ID (VUID) tags into the specification source files for
    explicit valid usage statements. This has no semantic effects on the
    specification, but will support the validation layer's detection of
    valid usage violations and allow it to link into the corresponding part
    of the specification (internal issue 583).
  * Assign VUID tags to all explicit VU statements and document
    the process and tag format in the style guide (internal issue 583).
  * Clarify the rules of whether to structure new functionality as instance
    extensions, device extensions, or both in the
    <<extended-functionality-instance-extensions-and-devices, Instance
    Extensions and Device Extensions>> section (internal issue 749).
  * Require that SPIR-V run-time arrays are only used with the
    code:BufferBlock decoration (internal issue 750).
  * Fix implicit and explicit valid usage statements for
    slink:VkWriteDescriptorSet::pname:dstSet (internal issue 767)
  * Fix SPIR-V code sample for ename:VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER
    in the <<descriptorsets-uniformtexelbuffer, Uniform Texel Buffer>>
    section (internal issue 770).
  * Clarify that disabling depth testing also disables depth writes in the
    <<fragops-ds-state, Depth and Stencil Operations>> section (internal
    issue 775).
  * flink:VkDescriptorImageInfo::pname:imageLayout must match the actual
    imageLayout at the time the image is accessed. This was in the spec
    text, but needed an associated valid usage statement.
  * Note that only 32-bit atomic operations are supported in the
    <<spirvenv-module-validation, Validation Rules within a Module>>
    section.
  * Note that code:UniformConstant variables must not have initializers in
    the <<spirvenv-module-validation, Validation Rules within a Module>>
    section.
  * Add a new elink:VkObjectType enumeration to the core API, promoted from
    elink:VkDebugObjectTypeEXT, since it is used for much more than just the
    debug_report extension.

New Extensions:

  * `VK_KHR_get_surface_capabilities2`
  * `VK_KHR_shared_presentable_image`

3e4bee3d11 Change log for March 10, 2017 Vulkan 1.0.43 spec update:
* Bump API patch number and header version number to 43 for this update.

Github Issues:

  * Make clearer that color write mask is applied regardless of whether
    blending is enabled, by referring to the
    <<framebuffer-color-write-mask,Color Write Mask>> section (public issue
    241).
  * Fix public issue 414:
  ** Added two new command buffer states (invalid, pending), and an explicit
     "command buffer lifecycle" section to explain them.
  ** Replaced "pending execution" with "in the pending state".
  ** Replaced a bunch of "this will invalidate the command buffer" language
     with "this will move the command buffer to the invalid state", and added
     validation language for what state those command buffers should be in.
  ** Added additional validation language about what state a command buffer
     should be in for various commands that affect it.
  ** Added invalidation language to destroy commands in the lifetimes section
     of fundamentals.
  ** Added command buffers to list of objects which must not be deleted
     whilst a (primary) command buffer is in the recording or pending state.
  * Update `GL_KHR_vulkan_glsl` extension to allow anonymous push constant
    blocks (public issue 428).

Internal Issues:

  * Document rules about extension interactions in the style guide (internal
    issue 579).
  * Require ename:VK_PRESENT_MODE_MAILBOX_KHR support in queries of surfaces
    created with flink:vkCreateWaylandSurfaceKHR using the
    VK_KHR_wayland_surface extension (internal issue 666).
  * Remove Valid Usage constraints for flink:vkAllocateDescriptorSets when
    the `VK_KHR_maintainance1` extension is present (internal issue 686).
  * Remove undocumented KHX-variants of vkGetPhysicalDeviceProperties2KHR
    and vkGetPhysicalDeviceImageFormatProperties2KHR from the
    <<VK_KHX_external_memory_capabilities>> and
    <<VK_KHX_external_semaphore_capabilities>> extensions.

New Extensions:

  * `VK_EXT_hdr_metadata`
  * `VK_GOOGLE_display_timing`
