Jon Leech e958791a01 Change log for March 16, 2018 Vulkan 1.1.71 spec update: 
* First public update for Vulkan 1.1.

Github Issues:

  * Refer to standard sparse image block shape format tables explicitly in
    the <<sparsememory-standard-shapes, Standard Sparse Image Block Shapes>>
    section (public issue 93).
  * Add the missing definition of the code:LocalInvocationIndex decoration
    in the <<interfaces-builtin-variables, Built-In Variables>> section
    (public issue 532).
  * Clarify dynamic state definition in the introduction to the <<pipelines,
    Pipelines>> section and the new <<pipelines-dynamic-state, Dynamic
    State>> subsection (public issue 620).
  * Clarified deprecation statement in the `VK_AMD_negative_viewport_height`
    appendix (public issue 674).
  * Fix parameter descriptions for flink:vkCreateIndirectCommandsLayoutNVX
    (public issue 677).

Internal Issues:

  * Remove description of <<primsrast-points, rasterization point size>>
    being taken from the tessellation control shader, since there are no
    circumstances under which you can have TCS without TES (internal issue
    522).
  * Define <<copies-images-format-size-compatibility, _size-compatible_
    image formats>> for flink:vkCmdCopyImage, add it to the glossary, and
    use that definition for slink:VkImageViewCreateInfo (internal issue
    771).
  * Change brief descriptions of enumerant names, and of parameters which
    are enumerants, from "`enum *indicates*`" to "`enum *specifies*`" for
    consistency, and add a markup style guide rule (internal issue 862).
  * Clarify how execution dependencies interact with
    <<synchronization-submission-order, submission order>> at numerous
    places in the <<renderpass, Render Pass>> and <<synchronization,
    Synchronization>> chapters (internal issue 1062).
  * Clarify statement in the <<interfaces-resources-setandbinding,
    DescriptorSet and Binding Assignment>> section that only interface
    variables statically used by the entry point used in a pipeline must be
    present in the descriptor set layout (internal issue 1172).
  * Flip sparse image diagrams with partially full mip levels vertically, to
    match graph origins of other image diagrams (internal issue 1176).
  * Update new SVG diagrams to have consistent style and base font size,
    increase consistency of primitive topology diagrams, and add a section
    to the style guide on creating and editing images in a consistent style
    (internal issue 1177).
  * Resolve problems with valid usage statement extraction by fixing
    existing VUID tags for interfaces promoted to version 1.1 and fixing
    conditional directives around
    VUID-VkMemoryDedicatedAllocateInfo-image-01797 (internal issue 1184).
  * Strip `KHR` suffixes from a few interfaces promoted to Vulkan 1.1 that
    were missed previously (internal issue 1185).
  * Restrict code:OpImageQuerySizeLod and code:OpImageQueryLevels to only
    work on code:Image operands with their code:Sampled operand set to 1. In
    other words, these operations are not defined to work with storage
    images (internal issue 1193).
  * Recycle extension slot for extension #82 in `vk.xml`. This extension was
    never published (internal issue 1195).
  * Add an issue to the `VK_KHR_maintenance1` appendix noting that zero
    height viewports are allowed when this extension is enabled (internal
    issue 1202).
  * Fix slink:VkDescriptorSetLayoutBinding description so that shader stages
    always use descriptor bindings, not the other way around (internal issue
    1206).
  * Fix field name for
    slink:VkInputAttachmentAspectReference::pname:inputAttachmentIndex
    (internal issue 1210).

Other Issues:

  * Fix a few broken links in the <<versions-1.1, Version 1.1>> appendix.
  * Replace a few old refBegin/refEnd tags with open block markup around
    interfaces, and remove old KHX VUID tags that were breaking the valid
    usage statement extraction.
  * Fix error codes accidentally tagged as success codes in `vk.xml` for
    flink:vkGetSwapchainCounterEXT.
  * Added valid usage statements for ftext:vkBind*Memory2 input structures
    stext:VkBind*MemoryInfo, and fix a pname:image -> pname:buffer typo in a
    couple of places.
  * Fix swapped descriptions of elink:VkDescriptorType enums
    ename:VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE and
    ename:VK_DESCRIPTOR_TYPE_STORAGE_IMAGE (reported via tweet).

New Extensions:

  * `VK_ANDROID_external_memory_android_hardware_buffer`

= Dispatching Commands
_Dispatching commands_ (commands with ftext:Dispatch in the name) provoke
work in a compute pipeline.
Dispatching commands are recorded into a command buffer and when executed by
a queue, will produce work which executes according to the currently bound
compute pipeline.
A compute pipeline must: be bound to a command buffer before any dispatch
commands are recorded in that command buffer.
[open,refpage='vkCmdDispatch',desc='Dispatch compute work items',type='protos']
--
To record a dispatch, call:
include::../api/protos/vkCmdDispatch.txt[]
* pname:commandBuffer is the command buffer into which the command will be
recorded.
* pname:groupCountX is the number of local workgroups to dispatch in the X
dimension.
* pname:groupCountY is the number of local workgroups to dispatch in the Y
dimension.
* pname:groupCountZ is the number of local workgroups to dispatch in the Z
dimension.
When the command is executed, a global workgroup consisting of
[eq]#groupCountX {times} groupCountY {times} groupCountZ# local workgroups
is assembled.
