Jon Leech 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`

Jon Leech 1d67e47f14 Change log for June 4, 2017 Vulkan 1.0.51 spec update:
* Bump API patch number and header version number to 51 for this update.

Github Issues:

  * Add Valid Usage statement to flink:vkCmdResolveImage to require that
    source and destination image formats match (public issue 492).
  * Specify that a code:char* parameter must: be a valid null-terminated
    string in the <<fundamentals-implicit-validity, implicit valid usage>>
    section (public issue 494).
  * Removed unnecessary VU for slink:VkPhysicalDeviceFeatures which is
    covered by ename:VK_ERROR_FEATURE_NOT_PRESENT already (public issue
    496).
  * Clarify valid usage of pname:pQueueFamilyIndices in
    slink:VkBufferCreateInfo, slink:VkImageCreateInfo, and
    slink:VkSwapchainCreateInfoKHR (public issue 501).
  * Document that dependencies of enabled extensions must also be enabled in
    the <<extended-functionality-extensions-dependencies, Extension
    Dependencies>> section (public issue 507).

Internal Issues:

  * Change slink:VkMappedMemoryRange valid usage to allow pname:offset +
    pname:size == size of the allocation. Also, if ename:VK_WHOLE_SIZE is
    used, require the end of the mapping to be aligned to a multiple of
    pname:nonCoherentAtomSize (internal issue 611).
  * Add issue to `VK_KHR_win32_surface` about reusing window objects from a
    different graphics API or Vulkan ICD (internal issue 639).
  * Require locations on user in/out in `GL_KHR_vulkan_glsl` (internal issue
    783).
  * Added version info to the json validation output, and updated the schema
    to match (internal issue 838).
  * Restructure enumerated type descriptions separately from the command or
    structure they are used in, allowing better reference page generation
    (internal issue 841).
  * Re-sort extension appendices to be in alphabetical order within each
    author ID section.
  * Fix enum naming and clarify behavior for
    `VK_NVX_device_generated_commands` extension.

Jon Leech cebb71d062 Change log for May 20, 2017 Vulkan 1.0.50 spec update:
* Bump API patch number and header version number to 50 for this update.

Github Issues:

  * Fix numerous minor issues with the VK_EXT_debug_report extension (public
    issues 478, 483, 486, 489, 490).

Internal Issues:

  * Update flink:vkAllocateDescriptorSets to specify conditions under which
    to return ename:VK_ERROR_FRAGMENTED_POOL or
    ename:VK_ERROR_OUT_OF_POOL_MEMORY instead of
    out-of-host/out-of-device-memory, and improve the
    <<fundamentals-errorcodes, description of those errors (internal issue
    654).
  * Add a NOTE documenting that flink:vkAcquireNextImageKHR can only signal
    a single semaphore, and how to deal with that when multiple physical
    devices in a logical device need to wait on it (internal issue 730).
  * Improve description of pname:pNext chains of
    slink:VkPhysicalDeviceImageFormatInfo2KHR and
    slink:VkImageFormatProperties2KHR (internal issue 814).
  * Clean up math markup issues in the <<textures, Image Operations>>
    chapter (internal issue 818).
  * Update validusage target to use more robust code for preprocessing, by
    making direct use of Asciidoctor's preprocessor. Added uniqueItems check
    to JSON vu schema and add clean_validusage target (internal issue 826).
  * Update style guide to prohibit writing non-self-contained (on a single
    bullet point) Valid Usage statements, and modify offending Valid Usage
    statements in the Specification to match, to assist with automatic
    extraction for the validation layers (internal issue 828).
  * Add ename:VK_VALIDATION_CHECK_SHADERS_EXT to elink:VkValidationCheckEXT
    of the `VK_EXT_validation_flags` extension, to selectively disable
    shader validation.
  * Remove duplicate valid usage statement for slink:VkImageMemoryBarrier.
  * Modify reflow.py script to place VUID tag anchors standalone on a line
    following their corresponding bullet point, and reflow the spec text
    accordingly (this had been pending since the initial tag deployment).

New Extensions:

  * `VK_AMD_texture_gather_bias_lod`

Jon Leech 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`

Jon Leech 43f1fd5550 Change log for March 17, 2017 Vulkan 1.0.44 spec update:
* Bump API patch number and header version number to 44 for this update.

Github Issues:

  * Fix description of <<features-extentperimagetype, Allowed Extent Values
    Based On Image Type>> (public issue 290).
  * Better specify VK_DEVICE_LOST behavior around flink:vkQueueSubmit,
    flink:vkWaitForFences, and flink:vkGetFenceStatus (public issue 423).
  * Clarify definition of flink:vkGetQueryPoolResults::pname:queryCount
    (public issue 441).
  * Simplify and clean up normative language. Remove shall and replace
    recommend and variants with should wherever possible (public issue 448).
  * Fix all dangling internal cross-references in the 1.0-extensions
    specification, and add scripts/checkXrefs to find these in the future
    (public issue 456).
  * Reverse order of ChangeLog.txt entries so the most recent version is
    documented first (public issue 463)
  * Removes "become invalid" which clashes with invalid state for command
    buffers. (public issue 467)
  * Disallowed pending state in spec text for vkResetCommandBuffer, matching
    valid usage (public issue 468)
  * Removes sentence describing invalid state "like initial state". (public
    issue 469)
  * Disallows begin command buffer from resetting command buffers in the
    "recording" state. (public issue 470)
  * Removes mention of state from description of
    VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT (public issue 471)
  * Removed extra valid usage statement in VkSubmitInfo (public issue 472)

Internal Issues:

  * Clarify description of the pname:imageLayout member of
    sname:VkDescriptorImageInfo.
  * Fix typos where etext:VK_VIEW_TYPE* was used instead of
    etext:VK_IMAGE_VIEW_TYPE.
  * Removed the <<VK_KHR_display>> and <<VK_KHR_display_swapchain>> example
    code from the specification and noted it has been moved to the Vulkan
    SDK cube demo (internal issue 179).
  * Reorder VkExternalMemoryHandleTypeFlagBitsNV description (internal issue
    480).
  * Clarify than an implementation is
    <<fundamentals-validusage-flags,permitted to return 'undefined' bit
    flags>> in a bitfield (internal issue 640).
  * Break Valid Usage statements describing unrelated parameters into
    separate statements, and add a style guide entry to follow this approach
    (internal issue 685).
  * Move valid usage statement for slink:VkImageCreateInfo from spec body to
    the explicit valid usage block (internal issue 693).
  * Fix typos in the descriptions of slink:VkDisplaySurfaceCreateInfoKHR,
    flink:vkCreateDisplayModeKHR, and
    flink:vkGetDisplayPlaneSupportedDisplaysKHR in the <<display,Presenting
    Directly to Display Devices>> section (internal issue 698, 704, 716).
  * Clarified that mandatory depth/stencil formats are only a requirement
    for 2D images (internal issue 719).
  * Clarify that variables decorated with DeviceIndex/ViewIndex must be in
    the Input storage class (internal issue 733).
  * Work around generator script problem with removal of Unicode literals
    from Python 3.0-3.2 using `future` package (internal issue 737).
  * Remove nonexistent structure type enums from vk.xml (internal issue
    738).
  * Fix validextensionstructs attributes for structures in the pname:pNext
    chain for VkPresentInfoKHR, fixing implicit valid usage statements for
    those structures (internal issue 740).

New Extensions:

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 348990517c Change log for September 30, 2016 Vulkan 1.0.29 spec update:
* Bump API patch number and header version number to 29 for this update.

Github Issues:

  * Remove redundant constraint on
    slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue
    224).
  * Fix typo and remove link in Note in the
    <<extended-functionality-instance-extensions-and-devices, Instance
    Extensions and Device Extensions>> section (public issue 359).
  * Fix erroneous validation statement for the pname:layout member of
    slink:VkComputePipelineCreateInfo (public issue 362).

Internal Issues:

  * Restore long figure captions using asciidoc sidebar blocks, due to
    restrictions of asciidoc syntax (internal issue 101).
  * Replace most latexmath equations with comparable markup in straight
    asciidoc, which significantly improves time required to fully load and
    process the HTML forms of the Specification. There are known minor font
    and alignment inconsistencies with MathJax and PDF rendering of
    latexmath equations. Please do not file github issues about these. We
    are aware of the inconsistencies and will make refinements over time,
    while the performance improvements are compelling in at least some major
    browsers (internal issue 313).
  * Move handcoded validity statements from +vk.xml+ into the Specification
    body, easing work in the single-branch model. Specify the distinction
    between these explicit statements, and the implicit validity statements
    inferred from vk.xml. Validity statements now appear in two blocks for
    each command and structure - handcoded "Valid Usage" and the implicit
    "Valid Usage (Implicit)" (internal issue 392).
  * Add the +returnedonly="false"+ attribute to WSI output structures,
    removing incorrectly generated implicit validity statements for
    slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR,
    slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR,
    slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures
    (internal issue 486).
  * Update slink:VkImageLayout to require the
    ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images
    (internal issue 487).
  * Use an explicit format specifier string for the date command invocation
    in the +Makefile+ instead of the shorthand -R option, which doesn't work
    on BSD and MaxOS X date commands (internal issue 500).

Other Issues:

  * Use the terms ``allocation scope'' and ``extension scope'' instead of
    just ``scope'', and add them to the glossary.
2016-09-30 21:13:37 -07:00
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).
2016-09-24 01:54:47 -07:00
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.
2016-09-16 21:22:17 -07:00
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
    )
  * Cleanup reference page builds so only core pages are built for releases.

Jon Leech 7f7686d7f2 Change log for August 5, 2016 Vulkan 1.0.23 spec update:
* Bump API patch number and header version number to 23 for this update.

Github Issues:

  * Add explicit valid value attributes to pname:sType members in vk.xml
    (public issue 34).
  * Clarify usage of flink:vkGetInstanceProcAddr and
    flink:vkGetDeviceProcAddr (public issue 225).
  * Fix a copy-and-paste error in the description of
    pname:pSwapchainImageCount saying that it was the count of ``format
    pairs'' instead of ``swapchain images'' (public issue 292).
  * flink:vkCmdExecuteCommandBuffers requires all command buffers to be
    allocated from command pools created for the same queue family (public
    issue 296).
  * Remove bogus +optional+ attribute for
    flink:vkEnumerateDeviceLayerProperties::pname:physicalDevice from vk.xml
    (public issue 301).
  * Clean up the <<resources-image-views-compatibility,image and image view
    compatibility table>> reference and contents. Use full enumerant names.
    Refer to pname:layerCount in the ``view parameters'' column instead of
    pname:arrayLayers. Require N >= 1 for the cube array subview row, not
    just arrayLayers >= 6 N (public issue 304).
  * Modify description of <<resources-memory-aliasing,memory aliasing>> to
    be consistent with the description of
    <<resources-bufferimagegranularity,buffer image granularity>> (public
    issue 307).

Internal Issues:

  * Describe remaining +vk_platform.h+ macros in the <<boilerplate,API
    Boilerplate>> appendix (internal issue 6).
  * Clarify
    <<features-features-robustBufferAccess,pname:robustBufferAccess>>
    feature behavior; what memory can be accessed, how bounds checking is
    performed, and allowing for vectorization (internal issue 332).
  * Document markup for automatic extraction of reference pages from the
    spec sources in the style guide (internal issue 395).
  * Allow flink:vkCreateDisplayModeKHR to return
    ename:VK_ERROR_INITIALIZAION_FAILED_KHR if the user requests mode
    parameters that the specified display does not support (internal issue
    411).
  * Remove atomic counters (atomic_uint style) from KHR_vulkan_glsl, and
    more clearly remove the subroutine keyword alongside it (internal issue
    421).
  * Clarify behavior of flink:vkCmdBindDescriptorSets for descriptor sets
    not contained in the layout (internal issue 427).

Other Commits:

  * Change the order in which members of sname:VkAttachmentDescription and
    sname:VkPipelineInputAssemblyStateCreateInfo are described to match
    their order in the structures.
2016-08-05 05:11:02 -07:00
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.
2016-07-23 03:15:48 -07:00
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).
2016-07-10 18:13:41 -07:00
Jon Leech 5de77cf663 Change log for June 10, 2016 Vulkan 1.0.16 spec update:
* Bump API patch number and header version number to 16 for this
    update.

Github Issues:

  * Clarify that integer border values are meant to be 0/1, and that
    integer texture lookups are sign-extended in the
    <<textures-format-conversion,Format Conversion>> and
    <<textures-texel-replacement,Texel Replacement>> sections (public
    issue 52).
  * Add logic to generate spec boilerplate without using the 'git'
    command-line client, needed when building from a tarball or another
    source of the Vulkan tree rather than a cloned git repo. Remove
    boilerplate as part of 'clean' target (public issue 195).
  * Document that color writes and clears to unused attachments have no
    effect for slink:VkClearAttachment and
    elink:VkColorComponentFlagBits (public issue 198).
  * Fixed flink:vkCmdExecuteCommands validity statement for
    sname:VkCommandBufferInheritanceInfo::pname:framebuffer. If used, it
    must match the framebuffer in the current renderpass instance
    (public issue 226).
  * Added valid usage language to require for all functions that set
    dynamic state that the currently bound graphics pipeline has the
    corresponding dynamic state enabled (public issue 235).

Internal Issues:

  * Clarify for flink:vkEnumerateInstanceExtensionProperties, in the
    <<extended-functionality-instance-extensions-and-devices, Instance
    Extensions and Device Extensions>> section, and in the
    <<glossary,Glossary>> section when functionality should be exposed
    as an instance extension, as a device extension, or as both
    (internal issue 109).
  * Place WorkgroupSize in alphabetical order in the
    <<interfaces-builtin-variables,Built-in Variables>> section
    (internal issue 323).
  * Corrects valid usage in vkEndRenderPass to only affect primary
    render passes, as secondaries may be entirely within a render pass,
    and should be able to be ended (previous language disallowed that)
    (internal issue 338).
  * Fix relational operator from <= to >= in the
    <<features-extentperimagetype,Allowed Extent Values>> section
    (internal issue 343).
  * Disallow recursion under SPIR-V entry points in the
    <<spirvenv-module-validation,Validation Rules within a Module>>
    section (internal SPIR-V issue 37).

Other Commits:

  * Use standard Python ElementTree package instead of lxml.etree in
    header / validation layer / include autogeneration from XML,
    reducing platform dependencies.

Jon Leech 2656f45933 Change log for May 13, 2016 Vulkan 1.0.13 spec update:
* Bump API patch number and header version number to 13 for this
    update.

Github Issues:

  * Improve the description of ename:VK_PRESENT_MODE_FIFO_RELAXED_KHR in the
    VK_KHR_surface extension (public issue 174).
  * Clarify use of etext:*_SIMULTANEOUS_USE_BIT for secondary command
    buffers (public issue 182).
  * Fix typos in VK_KHR_wayland_surface extension where code:wl_device was
    used instead of code:wl_display (public issue 193).
  * Replaced {apiname} with ``Vulkan'' in XML validity statements (public
    issue 199).
  * Fix dead links for WSI handle types (public issue 200).
	*** N.b. this needs to be done in WSI branches as well ***
  * Use "signaled" instead of "signalled" spelling everywhere (public issue
    201).
	*** N.b. this needs to be done in WSI branches as well ***
  * Move readme.pdf target directory for XML schema documentation into the
    target generation directory, instead of leaving it checked into the spec
    source tree (public issue 203).
	*** N.b. need to add generated PDF to registry index/1.0 page
  * Fix duplicate 'which which' typo in description of
    elink:VkCommandPoolResetFlagBits (public issue 204).
  * Move the <<Programmable Primitive Shading>> section up one level, out of
    the <<drawing-primitive-topologies,Primitive Topologies>> section
    (public issue 209).

Internal Issues:

  * Clarify in the <<pipelines-cache,Pipeline Cache>> section that
    implementations should not manage the size of pipeline cache (internal
    issue 192).
  * Deprecate the concept of device layers and associated commands (internal
    issue 255).
  * Remove ename:VK_INCOMPLETE from the list of possible result codes of
    flink:vkGetPhysicalDeviceSurfaceCapabilitiesKHR (internal issue 314).
  * Add missing std140/std430 rule: the base alignment of a member following
    a structure is a multiple of the structure's base alignment (internal
    issue 321).
  * Fixes naming of the single elink:VkColorSpaceKHR enum from
    ename:VK_COLORSPACE_SRGB_NONLINEAR_KHR to
    ename:VK_COLOR_SPACE_SRGB_NONLINEAR_KHR in XML/header and the
    VK_KHR_swapchain and VK_KHR_surface extensions to match the style of the
    typename (space and color are two words, not one) (internal issue 322).
  * Make it clear that code:LocalInvocationID should only be applied to an
    input variable and normalize the language describing
    code:LocalInvocationID to the language for other compute shader
    variables in the <<interfaces-builtin-variables,Built-in Variables>>
    section, and add normative language (internal issue 323).
  * Clarify in the <<fundamentals-returncodes,Return Codes>> section that
    the result pointer may be modified for specific commands, even if a
    runtime error is returned (internal issue 324).
2016-05-13 17:01:59 -07:00
Jon Leech 75bbb5f4d5 Change log for April 29, 2016 Vulkan 1.0.12 spec update:
* Bump API patch number and header version number to 12 for this
    update.

Github Issues:

  * Change valid usage statements intended to be "sub-points" to
    be actual sub-points (public issue 66).
  * Replace double negation in description of
    slink:VkRenderPassBeginInfo::pname:pClearValues (based on public
    merge 142).
  * Cleanup minor typos in spec, ref pages and XML, including those
    proposed in public pull requests 144, 150, 151, 167, 168, 181, and
    186.
  * Use *strict subset* in describing the partial order of memory
    property types for slink:VkMemoryType, and update the style guide
    accordingly (public issue 190).
  * Fix various "a image" -> "an image" typos (public issue 191).
  * Note in the <<fundamentals-validusage,Valid Usage>> and
    <<extensions-interactions,Extension Interactions>> sections that
    structures defined by extensions which may be passed in structure
    chains using the ptext:pNext member must: include initial
    ptext:sType and ptext:pNext members (public issue 192).

Internal Issues:

  * Remove duplicate language from the description of the pname:fence
    parameter to flink:vkQueueSubmit and improve validity language
    (internal issue 91).
  * Added documentation for "optional" attribute to XML readme.tex/pdf
    (internal issue 149).
  * Clarify the host-side data validity rules and behavior of
    flink:vkFlushMappedMemoryRanges and
    flink:vkInvalidateMappedMemoryRanges (internal issue 266).

Other Commits:

  * Added clarification to flink:vkCmdFillBuffer regarding the use of
    ename:VK_WHOLE_SIZE.
  * Fixed and documented implementation of "validextensionstructs"
    attribute. in XML processing scripts and readme.tex/pdf.
  * Add missing validity statements to flink:vkResetEvent and
    flink:vkCmdResetEvent.
  * Fix validity for the
    ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT flag.
    Correct all the draw/dispatch commands to mention optimally tiled
    images as well as linear tiled images, and say image VIEWS instead
    of images. Add validity statement to flink:vkCmdBlitImage
  * Replace the {apiname} macro with hardcoded "Vulkan", now that we've
    committed to that name.
  * Add the VK_AMD_rasterization_order extension to vk.xml.
2016-04-29 14:53:46 +02:00
Jon Leech 6db51e9241 Change log for April 22, 2016 Vulkan 1.0.11 spec update:
* Bump API patch number and header version number to 11 for this
    update.

Github Issues:

  * Clarify the WSI extension language by switching from the fuzzier
    "ownership" language to more-consistent "acquire" language (public
    issue 117).
  * Clarify that memory barriers apply to all commands in the dependency
    chains in the flink:vkGetRenderAreaGranularity command and the
    <<synchronization-execution-and-memory-dependencies,Execution And
    Memory Dependencies>> section (public issue 132).
  * Clarify that a queue family is a set of queues in the
    <<fundamentals-execmodel,Execution Model>> section (public issue
    166).
  * Removed requirement from valid usage language that
    VkPresentInfoKHR::waitSemaphoreCount must be greater than 0 (public
    issue 171).
  * Fix broken internal links, describe structures consistently, use
    consistent style for SPIR-V codewords, and tag normative terms that
    were missing asciidoc tags (public issue 183 and ancillary
    markup/normative language fixes).
  * Fix typos for slink:VkPhysicalDeviceLimits member names in
    slink:VkImageCreateInfo validity language (public issue 184).

Internal Issues:

  * Document that the requested patch version number specified as part
    of slink:VkApplicationInfo::pname:apiVersion is ignored when
    creating an instance (internal issue 176).
  * Clarify handling of extension structs in the
    <<fundamentals-validusageValid Usage>> section (internal issue 254).
  * Update required slink:VkImageFormatProperties::pname:maxMipLevels to
    be limited to the maximum allowed mipmap pyramid size corresponding
    to the actual maximum supported size for the format (internal issue
    256).
  * Modify the <<features-extentperimagetype,Allowed Extent Values Based
    On Image Type>> section so the allowed maximum extent is the maximum
    image dimension supported for each dimension of the type of texture
    being queried (internal issue 257).
  * Clarify in the <<spirvenv-module-validation,Validation Rules within
    a Module>> section that at least one of the code:LocalSize execution
    mode or code:WorkgroupSize decoration is required for each compute
    shader entry point in a shader module (internal issue 279).
  * Add validity rules for formats in flink:vkCmdClearColorImage and
    flink:vkCmdClearDepthStencilImage (internal issue 283).
  * Clarify that slink:VkImageFormatProperties::pname:maxResourceSize is
    an upper bound, and that it may not be possible to create an image
    anywhere near that size (internal issue 284).

Other Commits:

  * Fix various minor markup errors reported by validation scripts.
  * Change copyright from Khronos Free Use License to Apache 2.0 license
    on relevant script/XML/header files. This does not affect the

2016-04-21 01:08:38 -07:00
Jon Leech 3b32b240f6 Change log for April 15, 2016 Vulkan 1.0.10 spec update:
* Bump API patch number and header version number to 10 for this
    update.

Github Issues:

  * Slightly tweak the <<memory-allocation,Host Memory>> allocator language
    so that an application wrapping the standard C alloc/free/realloc
    functions is still correct - the previous language was too strong with
    regards to freeing memory. Also made certain scenarios clearer - an
    implementation may now continue without error if an allocation failed
    and it is able to continue correctly (public issue 21).
  * Require that etext:VK_*_CREATE_SPARSE_BINDING_BIT is set when the
    corresponding etext:VK_*_CREATE_SPARSE_RESIDENCY_BIT is used, in the
    <<sparsememory-miptail,Mip Tail Regions>> section and related commands
    flink:vkCreateBuffer and flink:vkCreateImage (public issue 84).
  * Update the <<features,Features, Limits, and Formats>> chapter to clarify
    interactions between optional features and dynamic state for the
    pname:depthBiasClamp and pname:wideLines features (public issue 89).
  * Describe the code:WorkgroupSize builtin in the
    <<interfaces-builtin-variables,Built-In Variables>> section, and update
    the <<compute-shaders,Compute Shaders>> section to further clarify how
    to set the number of workgroups to execute in a compute shader (public
    issue 145).
  * Use the term *image subresource* everywhere instead of *subresource*,
    except for the special case of *host-accessible subresource*, which may
    be either an image subresource or buffer range (public issue 120)
  * Add a note to the <<features,Features, Limits, and Formats>> section
    about extensibility of structures (Public issue 165).
  * Fix return code flink:vkAcquireNextImageKHR when the timeout parameter
    is 0 to ename:VK_NOT_READY instead of ename:VK_TIMEOUT (public issue
    170).
  * Fix typo in slink:VkLayerProperties::pname:apiVersion field (public
    issue 172).

Internal Issues:

  * Fix a few minor internally-detected typos.
  * Minor formatting tweaks to pseudocode in the <<resources,Resource
    Creation>> chapter (internal issue 179).
  * Fix typo in the definition of point sampling for
    elink:VkCullModeFlagBits (internal issue 268).
2016-04-14 01:58:49 -07:00
Jon Leech 1f875738fd Change log for March 10, 2016 Vulkan 1.0.6 spec update:
* Bump API patch number and header version number to 6 for this
    update.

Github Issues:
  * Define 'invocation group' for compute and graphics shaders. Cleanup
    definition and use of 'workgroup', and add glossary entries (public
    issue 1).
  * Various minor editorial fixes (public issue 33).
  * Clarify locations for block members in the
    &lt;&lt;interfaces-iointerfaces-locations,Location Assignment>>
    section (public issue 45).
  * Editorial fixes for &lt;&lt;commandbuffer-allocation,Command Buffer
    Allocation>> section (public issues 54, 59).
  * Clarify behavior of depth test in the &lt;&lt;fragops-depth,Depth
    Test&gt;&gt; section (public issues 80, 81).
  * Remove discussion of return codes from
    flink:vkGetPhysicalDeviceSparseImageFormatProperties and
    flink:vkGetImageSparseMemoryRequirements, which don't return values
    (public issue 82).
  * Allow flink:vkCmdDrawIndirect and flink:vkCmdDrawIndexedIndirect
    pname:drawCount of 0, as well as 1, when the multiDrawIndirect
    feature is not supported (public issue 88).
  * Remove confusing wording in the &lt;&lt;features-limits,Limits>>
    section describing the slink:VkPhysicalDeviceLimits
    pname:minTexelBufferOffsetAlignment,
    pname:minUniformBufferOffsetAlignment, and
    pname:minStorageBufferOffsetAlignment members as both minimums and
    maximums (public issue 91).
  * Clarified that only the RGB components should be affected in places
    where sRGB is referred to in the spec, such as ASTC formats. Minor
    re-wording to avoid "color space" when actively incorrect, now that
    we refer to the Data Format Spec which actually makes a distinction
    between color space and transfer function (public issue 94).
  * Treat pname:pPropertyCount == 0 consistently in
    flink:vkEnumerateInstanceLayerProperties and
    flink:vkEnumerateDeviceLayerProperties (public issue 99)
  * Cleanup minor editorial issues in chapters 14-17 (public issue 100).
  * Clarify definition of flink:vkEnumerateInstanceExtensionProperties
    and flink:vkEnumerateDeviceExtensionProperties (public issue 101).
  * Define the flink:vkEnumerateInstanceExtensionProperties and
    flink:vkEnumerateDeviceExtensionProperties pname:pLayerName
    parameter to be a pointer to a null-terminated UTF-8 string (public
    issue 101).
  * Rearrange "Missing information" references in mandatory format
    tables (public issue 101).
  * Clarify that the enumerated extensions returned by
    flink:vkEnumerateInstanceExtensionProperties and
    flink:vkEnumerateDeviceExtensionProperties will only include
    extensions provided by the platform or extensions implemented in
    implicitly enabled layers (public issue 101).
  * Miscellaneous editorial fixes. Include the Vulkan spec patch number
    in the PDF title. Fix label on &lt;&lt;fig-non-strict-lines,Non
    strict lines>> diagram. Use more easily distinguished symbols in
    tables in the &lt;&lt;features-required-format-support,Required
    Format Support>> section. Don't require FQDNs used as layer names be
    encoded in lower case if not possible, in the
    &lt;&lt;extensions-naming-conventions, Extension and Layer Naming
    Conventions>> section (public issues 101, 119, 121).

Internal Issues:
  * Fixed excessive spacing in tables in XHTML (internal issue 18).
  * Clarify that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT
    applies to secondary command buffers. Previously spec only referred
    to the members of pname:pCommandBuffers being affected by this bit.
    Added a separate slink:VkSubmitInfo Valid Usage restriction
    specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT
    also applies to any secondary command buffers that are recorded into
    the primary command buffers in pname:pCommandBuffers (internal issue
    106).
  * Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be
    NULL (internal issue 117).
  * Remove "the value of" where it is redundant (e.g. speaking of an API
    parameter, struct member, or SPIR-V variable, but not when speaking
    of color components) (internal issue 175).
  * Forced patch version to always be 0 in the header. Add a
    "VK_API_VERSION_<major>_<minor>" macro for people to use to do the
    right thing. Add a VK_HEADER_VERSION which captures the header
    release number independent of the spec patch number (internal issue
    176).
  * Correct description of
    slink:VkPipelineShaderStageCreateInfo::pname:pName to "a pointer to
    a null-terminated UTF-8 string" (internal issue ).

Other Commits:
  * Updated DataFormat spec reference to the new date for revision 5 of
    that spec.
  * Fixed KEEP option (to retain LaTeX intermediate files) in the
    Makefile to be included when edited there, as well as set on the
    command line.
  * Reserve and add "VK_IMG_filter_cubic" to the registry, and implement
    script functionality to add and remove validity from existing
    functions. Includes schema and readme changes.
  * Update GL_KHR_vulkan_glsl so push_constants do not have descriptor
    sets.

Jon Leech 7380aee56b Change log for March 4, 2016 Vulkan 1.0.5 spec update:
* Bump API patch number to 5 for this update.

Github Issues:
  * Correctly describe slink:VkPhysicalDeviceProperties pname:deviceName
    member as a string, not a pointer to a string. Also one typo fix for
    "hetereogeneous" (public issue 4).
  * Replace maynot: macro with may: not, and "may: or maynot:" with
    "may:" (public issue 4).
  * Clarify that redundantly setting the state of a fence or event has
    no effect (public issue 4).
  * Minor fixes to ref pages to track descriptions of memory bits that
    changed in the core spec. Fix name of a member in the description of
    sname:sname:VkPipelineMultisampleStateCreateInfo (public issues 8,
    13).
  * Remove redundant validity statement for
    sname:VkGraphicsPipelineCreateInfo::pname:stageCount (public issue
    14).
  * Fix typos in chapters 7-9 (public issue 14).
  * Clarify the example demonstrating the behavior of
    code:OpMemoryBarrier in the
    &lt;&lt;shaders-execution-memory-ordering,shader memory acces
    ordering>> section (public issue 16).
  * Specify that freeing mapped memory implicitly unmaps the memory in
    the description of flink:vkFreeMemory (public issue 17).
  * Forbid allocation callbacks from calling into the API in the
    &lt;&lt;memory-allocation,memory allocation>> section (public issue
    20).
  * Add missing validity rules about size being greater than 0 and
    offset being less than size of object. Fix
    flink:VkMappedMemoryRange's misinterpretation of offset (public
    issues 27, 31).
  * Add validity rule disallowing overlapping source/destination
    descriptors in flink:VkCopyDescriptorSet (public issue 32).
  * Clarify that array and matrix stride has to be a multiple of the
    base alignment of the array or matrix in the
    &lt;&lt;interfaces-resources-layout,Offset and Stride Assignment>>
    section (public issue 38).
  * Correct parenthesis floor nesting error in equation for
    &lt;&lt;textures-RGB-sexp,RGB to shared exponent conversion>>.
    Clarify case of when exp' is forced to 0, avoiding log2(0) undefined
    problem (public issue 40).
  * Remove redundant statement from the code:FragDepth description in
    the &lt;&lt;interfaces-builtin-variables,Built-In Variables>>
    section (public issue 47).
  * Define the clamping of the
    &lt;&lt;textures-level-of-detail-operation,bias added to the scale
    factor>> by linking to the slink:VkPhysicalDevice feature
    pname:maxSamplerLodBias (public issue 64).
  * Fix typo "optimal linear resources" and clarify the set of resources
    &lt;&lt;features-limits-bufferImageGranularity,the
    pname:bufferImageGranularity resource>> applies to (public issue
    67).
  * Replace 'descriptor accessed by a pipeline' language for
    sname:VkDescriptorSetAllocateInfo with more precise phrasing about
    binding a descriptor set before a command that invokes work using
    that set (public issue 69).
  * tstripadj.svg contained an Inkscape tag which caused Firefox and IE
    11 to fail to render it, and was illegal SVG. Generating Plain SVG
    from the Inkscape SVG source fixes this (public issue 70).
  * Fix validity for sname:VkVertexInputBindingDescription and
    sname:VkVertexInputAttributeDescription numbers (public issue 72).

Internal Issues:
  * Clarify the meaning of
    ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT in
    elink:VkFormatFeatureFlagBits with respect to depth compare
    (internal issue 107).
  * Added a note explaining that ename:VK_QUEUE_TRANSFER_BIT may or may
    not be reported for a queue family that already supports
    ename:VK_QUEUE_GRAPHICS_BIT or ename:VK_QUEUE_COMPUTE_BIT as the
    former is a strict subset of the latter ones (internal issue 116).
  * Add validity language for sname:VkDescriptorSetAllocateInfo about
    exceeding the descriptor pool capacity (internal issue 140).
  * Add ename:VK_INCOMPLETE success code for
    flink:vkEnumeratePhysicalDevices query (internal issue 163).

Other Commits:
  * Add the VK_NV_glsl_shader extension definitions to the API.
  * Update GL_KHR_vulkan_glsl with 1) origin_upper_left as default 2)
    specialization array constant semantics.
  * Corrected/updated Data Format Specification date.

Jon Leech 1f35f84e2b Fixes for (public issue 101)
This is for people to review edits for @philiptaylor's points, but I'll
probably pull equivalent changes back into the private repo and merge
there before bringing it back to github in one of the (hopefully) weekly
updates.

[ChangeLog] This bundles up low-hanging editorial issues from public issue
101. Some items from that issue are more complex and remain to be done.
There's also some related cleanup of the extensions appendix to clarify the
distinction between a Vulkan API command, and the functions and function
pointers corresponding to that command which may be provided by the API
loader and runtime.

Remaining todo from  :

- [ ] 24.5.1 "Ab, Yb, Zb" -> "Xb, Yb, Zb".
- [ ] 29.2 "explicitly enabled layers" clarification.
- [ ] 30.3.3 Confusingly similar tiny circle symbols in format tables.
- [ ] 30.3.3 Missing information about some formats.
- [ ] C.3 Clarify or punt on "lower-case UTF-8" in FQDN layer names.

Jon Leech 5a4c5e5925 Change log for February 25, 2015 Vulkan 1.0.4 spec update:
* Bump API patch number from 3 to 4 for the first public update to the
    spec. Add patch number to the spec title (this will be done
    automatically from XML, later).
  * Fixes for numerous editorial issues. Regularize descriptions of
    variable-length array queries. Properly tag enumerants so they come
    out in the right font (many were mislabeled in usage tags in vk.xml,
    or not tagged). Spelling and markup corrections (public issue 4).
  * Fix typos and clearly separate description of different types of
    memory areas (public issue 5).
  * Use standards-compliant preprocessor guard symbols on headers
    (public issue 7).
  * Note that Github users can't currently set labels on issues, and
    recommend a fallback approach (public issue 15).
  * Use latexmath prefix on len= attributes (public issue 29).
  * Make flink:vkCmdUpdateBuffer pname:dataSize limit consistent (public
    issue 65).
  * Add VK_KHR_mirror_clamp_to_edge extension to core API branch, as an
    optional feature not introducing new commands or enums (internal
    issue 104).
  * Cleanup invariance language inherited from the GL specification to
    not refer to nonexistent (GL-specific) state (internal issue 111).
  * Modify the flink:vkCmdDrawIndexed pname:vertexOffset definition to
    not be the "base offset within the index buffer" but rather the
    "value added to the vertex index before indexing into the vertex
    buffer" (internal issue 118).
  * Fix drawing chapter in the "Programmable Primitive Shading" section
    where it described categories of drawing commands. It referenced
    flink:vkCmdDrawIndexed twice. Replace the second reference with
    flink:vkCmdDrawIndexedIndirect (internal issue 119).
  * Typo fixed in <<sparsememory-examples-advanced,Advanced Sparse
    Resources>> sparse memory example (internal issue 122).
  * Add flink:VkDisplayPlaneAlphaFlagsKHR to <require> section of
    VK_KHR_display extension (internal issue 125)
  * Add missing optional="false,true" to
    flink:vkGetImageSparseMemoryRequirements
    pname:pSparseMemoryRequirementCount parameter (internal issue 132)
  * Rename ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CREATE_INFO_EXT to
    ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CALLBACK_CREATE_INFO_EXT
    (internal issue 133)
  * Fix a handful of broken cross-references in the
    <<samplers,Samplers>> chapter (internal issue 134).
  * Fix "Input Attachement" GLSL example to use correct syntax (internal
    issue 135).
  * Update XML schema and documentation to accomodate recently added
    attributes for validity. Add some introductory material describing
    design choices and pointing to the public repository to file issues.
  * Put include of validity in the core spec extensions chapter on its
    own line, so that asciidoc is happy.
  * Fix vertexOffset language to specify that it's the value added to
    the vertex index before indexing into the vertex buffer, not the
    base offset within the index buffer.
  * Fix error in the description of flink:vkCmdNextSubpass.
