Jon Leech df88ded281 Change log for September 5, 2017 Vulkan 1.0.60 spec update:
* Bump API patch number and header version number to 60 for this update.

Github Issues:

  * Document that <<queries-timestamps, Timestamp Queries>> can only be
    meaningfully compared when they are written from the same queue (public
    issue 216).
  * Document that the `<extension>` tag `type` attribute is required for
    non-disabled extensions (derived from, but does not close public issue
    354).
  * Clean up registry schema length attribute descriptions to be consistent
    and correct (public issue 555).

Internal Issues:

  * Replace as much of the hand-written extension appendix metadata as
    possible with asciidoc includes generated from corresponding attributes
    of +vk.xml+, and enhance the style guide to match. This avoids
    inconsistencies between +vk.xml+ and the appendices, and produces a more
    uniform style (internal issue 137).
  * Remove the generated extDependency.{py,sh} files from the tree and
    create them dynamically on demand instead, reducing merge conflicts
    (internal issue 713).
  * Add a prototype tool for generating in-place difference markup for
    sections guarded by asciidoc conditionals, and new syntax for open
    blocks to support it (internal issue 833).
  * Remove unnecessary restriction of etext:*SYNC_FD_BIT_KHR external handle
    types to the same physical device in the
    slink:VkPhysicalDeviceIDPropertiesKHR,
    flink:VkImportMemoryWin32HandleInfoKHR,
    slink:VkImportFenceWin32HandleInfoKHR, slink:VkImportFenceFdInfoKHR,
    slink:VkImportSemaphoreWin32HandleInfoKHR,
    slink:VkImportSemaphoreFdInfoKHR
    <<external-memory-handle-types-compatibility, External memory handle
    types compatibility>>, <<external-semaphore-handle-types-compatibility,
    External semaphore handle types compatibility>>, and
    <<external-fence-handle-types-compatibility, External fence handle types
    compatibility>> sections (internal issue 956).

Other Issues:

  * Remove dependency of +VK_KHX_device_group+ on +VK_KHR_swapchain+ (there
    is an interaction, but not a strict dependency), and add a new
    `extension` attribute to the `<require` XML tag to allow classifying a
    subset of interfaces of an extension as requiring another extension.
    Update the registry schema and documentation accordingly.

New Extensions:

  * `VK_AMD_shader_fragment_mask` (and related `GL_AMD_shader_fragment_mask`
    GLSL extension)
  * `VK_EXT_sample_locations`
  * `VK_EXT_validation_cache`

Jon Leech 82e0f83d43 Change log for February 10, 2017 Vulkan 1.0.40 spec update:
* Bump API patch number and header version number to 40 for this update.
  * There is a major build change in this release. We are now using the
    Ruby-based ``asciidoctor'' implementation, rather than the Python-based
    ``asciidoc'' implementation, to process the specification. While the
    actual specification markup changes were minimal, this requires a new
    set of build tools and a very different installation process, especially
    because we now use an experimental direct-to-PDF backend for Asciidoctor
    instead of Docbook->dblatex->PDF. It is no longer possible to build the
    Specification using asciidoc. See doc/specs/vulkan/README.adoc
    for some guidance on installing the new toolchain components.
  * There are some minor rendering issues in the PDF output due to teething
    problems with the asciidoctor toolchain, especially with mathematical
    equations. We are aware of these and working on them.

Github Issues:

  * Updated sample code for the <<sparsememory-examples-basic,sparse
    resource binding example>> (public issue 97).
  * Modify line and point clipping behavior in the
    <<vertexpostproc-clipping, Primitive Clipping>> section to allow for
    pop-free behavior. The ability to check for which behavior is
    implemented may be added a future feature or extension (public issue
    113).
  * Unify the discussions of implicit ordering throughout the spec, in
    particular in the new sections <<drawing-primitive-order, Primitive
    Order>>, <<primrast-order, Rasterization Order>>, and
    <<synchronization-implicit, Implicit Synchronization Guarantees>>; the
    discussion of <<synchronization-submission-order, submission order>>;
    and references elsewhere to these sections (public issue 133).
  * Clarify \<\<descriptorsets-compatibility,Pipeline Layout Compatibility>>
    language and introduce the term ``identically defined'' (public issue
    164).
  * Add a dependency to the +VK_EXT_debug_marker+ extension that's needed to
    reuse the object type enum from +VK_EXT_debug_report+, and moves the
    definition of that enum into +VK_EXT_debug_report+ where it should be
    (public issue 409).
  * Remove redundant valid usage statement from slink:VkImageBlit (public
    issue 421).
  * Update GL_KHR_vulkan_glsl to allow the ternary operator to result in a
    specialization constant (public issue 424).
  * Fix valid usage for flink:VkPipelineShaderStageCreateInfo (public issue
    426).
  * Correct typo in New Objects list for <<VK_EXT_debug_report>> (public
    issue 447).

Internal Issues:

  * Moved to asciidoctor for spec builds (internal issue 121).
  * Update style guide to describe where to put new extensions-specific
    asciidoc files, and what to name them (internal issue 626).
  * Add src/spec/indexExt.py to autogenerate registry index entries linking
    into the 1.0-extensions specification, instead of maintaining the index
    manually. (internal issue 642).
  * Autogenerate extension dependencies and lists of all extensions and all
    KHR extensions from the "supported" attributes in +vk.xml+. Execute
    +make config/extDependency.sh+ from +doc/specs/vulkan+ when a supported
    extension is added to vk.xml, to regenerate the dependency script. The
    consequence is that specifying a single extension to the +makeExt+
    script will automatically enable all extensions it depends on as well,
    and that the +makeAllExts+ and +makeKHR+ scripts do not need to be
    updated when a new extension is supported (internal issue 648).
  * Put extension appendices all at the same asciidoc section level, so KHR
    WSI extensions show up in the HTML index (internal issue 648).

Other Issues:

  * Imbed images in the generated HTML specs instead of loading them from
    the images/ directory.
  * Fix missing EXT in extension name
    (ename:VK_EXT_SWAPCHAIN_COLOR_SPACE_EXTENSION_NAME).
  * Add new +VK_EXT_SMPTE_2086_metadata+ extension.
  * In the <<platformCreateSurface_xlib,Xlib Surface>> section of the
    +VK_KHR_xlib_surface+ specification, add language warning users that
    they always need to call code:XinitThreads.
  * Use the term "presentable image" (rather than "swapchain image")
    consistently in +VK_KHR_swapchain+ and related extensions, and add a
    glossary term defining it.
  * Relocate the valid usage for samples of
    flink:vkGetPhysicalDeviceSparseImageFormatProperties2KHR::pname:pFormatInfo
    to be below the flink:VkPhysicalDeviceSparseImageFormatInfo2KHR
    structure.

Jon Leech ca4abe0d34 Change log for January 23, 2017 Vulkan 1.0.39 spec update:
* Bump API patch number and header version number to 39 for this update.

Github Issues:

  * Clarified that only accesses via the specified buffer/image subresource
    ranges are included in the access scopes (public issue 306).
  * Add missing valid usage statements for flink:vkCreateComputePipelines
    and flink:vkCreateGraphicsPipelines (public issue 427).

Internal Issues:

  * Add a Note to the <<invariance,Invariance>> appendix about a difference
    between OpenGL and Vulkan with regards to how primitives derived from
    offsets are handled (internal issue 355).
  * Add the +<<VK_KHR_get_physical_device_properties2>>+,
    +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+
    extensions (internal issue 448).
  * Add the +<<VK_EXT_shader_subgroup_vote>>+ and
    +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449).
  * Update the texture level-of-detail equation in the
    <<textures-scale-factor,Scale Factor Operation>> section to better
    approximate the ellipse major and minor axes (internal issue 547).
  * Forbid non-explicitly allowed uses of interface decorations in the
    introduction to the <<interfaces,Shader Interfaces>> chapter (internal
    issue 607).
  * Replace use of MathJax with KaTeX, for improved load-time performance as
    well as avoiding the scrolling-and-scrolling behavior due to MathJax
    asynchronous rendering when loading at an anchor inside the spec. This
    change also requires moving to HTML5 output for the spec instead of
    XHTML, and there is a visible difference in that the chapter navigation
    index is now in a scrollable sidebar instead of at the top of the
    document. We may or may not retain the nav sidebar based on feedback
    (internal issue 613).
  * Improve consistency of markup and formatting in extension appendices
    (internal issue 631).

Other Issues:

  * Add explicit valid usage statements to slink:VkImageCopy requiring that
    the source and destination layer ranges be contained in their respective
    source and destination images.
  * Add valid usage language for swapchain of flink:vkAcquireNextImage. If
    the swapchain has been replaced, then it should not be passed to
    flink:vkAcquireNextImage.
  * Add a valid usage statement to flink:vkCreateImageView, that the image
    must have been created with an appropriate usage bit set.
  * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of
    slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section.
  * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor
    to account for the multiple viewport feature. If the feature is not
    enabled, the parameters for these functions have required values that
    are defined in the <<features-features-multiViewport,multiple
    viewports>> section of the spec but were not reflected in the valid
    usage text for these functions.
  * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common
    color spaces.

Jon Leech 789549ff08 Change log for November 25, 2016 Vulkan 1.0.35 spec update:
* Bump API patch number and header version number to 35 for this update.

Github Issues:

  * Document in the <<memory-device-hostaccess,Host Access>> section that
    mapping and unmapping does not invalidate or flush the mapped memory
    (public issues 27, 126).
  * Redefine the entire <<synchronization>> chapter in terms of consistent
    and well defined terminology, that's called out at the start of the
    chapter. This terminology is applied equally to all synchronization
    types, including subpass dependencies, submissions, and much of the
    implicit ordering stuff dotted around the spec. Key terms are laid out
    in the <<synchronization-dependencies,Execution and Memory
    Dependencies>> section at the top of the rewritten chapter (public
    issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407).
  * Specify order of submission for batches in the
    <<vkQueueSubmit,vkQueueSubmit>> and
    <<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371).
  * Add valid usage statements to each of the WSI extension sections
    indicating that the WSI-specific structure parameters must be valid, and
    remove automatically generated valid usage statements now covered by the
    manual sections (public issue 383).
  * Clarify render pass compatibility for flink:vkCmdExecuteCommands (public
    issue 390).

Internal Issues:

  * Update +vk.xml+ to make previously explicit valid usage statements for
    <<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead
    (internal issue 553).
  * Add valid usage statement for slink:VkCreateImageInfo preventing
    creation of 1D sparse images (internal issue 573).
  * Fix Python scripts to always read/write files in utf-8 encoding, and a
    logic error in reflib.py which could cause a fatal error for
    malstructured asciidoc (internal issues 578, 586).

Jon Leech 95dd2f34c5 Change log for September 23, 2016 Vulkan 1.0.28 spec update:
* Bump API patch number and header version number to 28 for this update.

Github Issues:

  * Minor spelling and typography cleanup, add definitions of
    ename:VK_FALSE and ename:VK_TRUE as just what their names say
    (public issues 220, 318, 325, 365; internal issues 451, 496)
  * Clarify that the pname:maxDescriptorSet limits in the
    <<features-limits-required,Required Limits>> table are n *
    maxPerStage limit (where n=number of supported stages) (public issue
    254).
  * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific
    Macro Definitions>> appendix (public issue 314).
  * Add valid usage statement to slink:VkPipelineLayoutCreateInfo
    disallowing multiple push constant ranges for the same shader stage
    (public issue 340).
  * Clarify the elink:VkSharingMode description of what executing the
    "same" barriers means in case of ownership transfer (public issue
    347).
  * Rename copyright.txt and add COPYING.md to try and reduce confusion
    about applicable copyrights (public issue 350).
  * Extend the table in the <<boilerplate-wsi-header, Window System-Specific
    Header Control>> section to describe the external headers included when
    each etext:VK_USE_PLATFORM_* macro is defined (public issue 376).

Internal Issues:

  * Add "Revision History" to the PDF outputs following the table of
    contents, to match HTML outputs (internal issue 43).
  * Clarified that flink:vkMapMemory may fail due to virtual address
    space limitations (internal issue 346).
  * Add +refBody+ comment markup for ref page autoextraction when required
    (internal issue 400).
  * Document proper use of "mipmap" and "mip" in the style guide API
    naming rules, matching the spelling rules (internal issue 471).
  * Tweak the <<extensions,Layers and Extensions>> appendix to note that
    the Specification may be built with arbitrary combinations of
    extensions (internal issue 483).
  * Remove incorrect statement allowing
    slink:VkClearAttachment::pname:colorAttachment to be >=
    slink:VkSubpassDescription::pname:colorAttachmentCount (internal
    issue 488).
  * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is
    expressed in terms of the pname:maxViewportDimensions but this is
    actually two values. Clarify that it's based on the larger of the two
    (if they differ) (internal issue 499).

Other Issues:

  * Reflowed text of the entire spec using the 'reflow' Makefile gater,
    to (hopefully) reduce future internal git churn as edits are made
    and extensions added in return for one-time pain. This has no
    perceptible change on the spec outputs but considerable changes on
    the asciidoc source (internal issue 367).

Jon Leech ef053e7c82 Change log for September 16, 2016 Vulkan 1.0.27 spec update:
* Bump API patch number and header version number to 27 for this update.

Github Issues:

  * Weaken flink:vkGetPipelineCacheData invariance conditions; previous
    conditions were stronger than agreed and can't be guaranteed (public
    issue 280).
  * Add link to "Vulkan Loader Specification and Architecture Overview"
    document to Normative References section (public issue 359).

Internal Issues:

  * Be more clear in the <<interfaces-resources-layout-std140, uniform
    buffer layout>> section that block offsets can be out of order
    (internal issue 396).
  * Document that extension authors should add support for their extensions
    to the validation layers (internal issue 398).
  * Clarify that the valid range of depth clear values should be limited
    to the 0..1 range and that copies to depth aspect must also be in this
    range (internal issue 412).
  * Specify ``a'' vs. ``an'' use in the style guide (internal issue 432).
  * Increase the maximum pname:nonCoherentAtomSize value in the
    <<features-limits-required,Required Limits>> section from 128 to 256
    (internal issue 435).
  * Fix vk_platform.h for compiler errors on some Android platforms
    (internal issue 441).
  * Clarify that slink:VkPhysicalDeviceFeatures::pname:pEnabledFeatures ==
    `NULL` disables all features, including the "required" feature
    pname:robustBufferAccess (internal issue 479).

Other Issues:

  * Expand style guide and make it more self-consistent.
  * Use ISO 8601 date format everywhere.
  * Emphasise the correct way of using
    slink:VkSurfaceCapabilitiesKHR::pname:maxImageCount.
  * Added +VK_EXT_validation_flags+ extension for validation flag mechanism.
  * Fix an <<credits,author credit>> to include their current employer.

Jon Leech eaea7d2709 Change log for September 6, 2016 Vulkan 1.0.26 spec update:
* Bump API patch number and header version number to 26 for this update.

Github Issues:

  * Bring sample code in the +VK_KHR_surface+ and +VK_KHR_swapchain+
    extension summary appendices up to date, and note they will be replaced
    with pointers to the LunarG SDK examples in the future (public issue
    279).
  * Add a new <<fundamentals-commandsyntax-results-lifetime,Lifetime of
    Retrieved Results>> section specifying that ftext:vkGet* and
    ftext:VkEnumerate* results are invariant unless otherwise specified, and
    specify behavior for individual commands which are not invariant (public
    issue 280).
  * Remove conflicting definition of
    slink:VkDisplayPlaneCapabilitiesKHR::pname:maxSrcPosition and clean up
    language of the remaining definition (public issue 351).
  * Fix many minor spelling errors and add rules to the style guide to
    prevent recurrences (public issue 352).

Internal Issues:

  * Remove redundant descriptions of the etext:VK_USE_PLATFORM_* macros from
    the <<wsi,Window System Integration>> chapter in favor of the
    description in the <<boilerplate-wsi-header,Window System-Specific
    Header Control>> appendix (internal issue 6).
  * Replace misleading 'can: be destroyed when not X' with more correct
    'must: not be destroyed while X' in the
    <<fundamentals-objectmodel-lifetime,Object Lifetime>> section. Disallow
    destroying a pipeline layout while a command buffer using it is
    recording (internal issue 241).
  * Clarify that ename:VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT is valid for
    all images used as attachments in elink:VkImageUsageFlagBits and the
    slink:VkImageLayout validity language (internal issue 320).
  * Note that <<extended-functionality-layers,Layers>> may wrap object
    handles, but that this is a generally discouraged. A link to additional
    information in the documentation for layer authors is provided (issue
    398)
  * Replace the mustnot: and shouldnot: macros with equivalent must: not and
    should: not to get rid of non-English words while still highlighting
    normative language (internal issue 407).
  * Disallow creating multisampled images with
    ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT in the slink:VkImageLayout
    validity language and the <<features-supported-sample-counts,Supported
    Sample Counts>> section (internal issue 445).
  * Fix typo so that flink:vkCmdDrawIndexedIndirect is defined in terms of
    flink:vkCmdDrawIndexed rather than flink:vkCmdDrawIndirect (internal
    issue 446).
  * Reorganize the per-extension information sections to all be in the
    <<extensions,Layers & Extensions>> appendix. Also fix a typo in
    +VK_IMG_filter_cubic+ which incorrectly identified it as a +KHR+
    extension (internal issue 461).

Other Issues:

  * Use asciidoc markup instead of latexmath to simplify diagrams in the
    <<features-formats-non-packed,byte mapping tables>> for color formats.
  * Fix a markup problem with the wildcarded enumerant names in a NOTE in
    the <<textures-texel-replacement,Texel Replacement>> section.
  * Fix missing attributes in the XML interface for
    elink:VkExternalMemoryHandleTypeFlagBitsNV and
    elink:VkExternalMemoryFeatureFlagBitsNV (KhronosGroup/Vulkan-Hpp issue
    #25)
  * Cleanup reference page builds so only core pages are built for releases.
