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).

Change log for March 25, 2016 Vulkan 1.0.7 spec update: * Bump API patch number and header version number to 7 for this update. Github Issues: * Fix slink:VkSpecializationMapEntry example to avoid C/C++ strict aliasing issues (public issue 14). * Clarify the meaning of "matching" in flink:vkCmdBindDescriptorSets validity language (public issue 33). * Add stub reference pages so xrefs to not-yet-written pages don't generate 404 errors. However, the actual content of these pages still needs to be filled in as time allows (public issue 44, but does not close that issue out). * Remove incorrect validity statement for flink:vkGetImageSparseMemoryRequirements (public issue 85). * Reword the <<features-limits-bufferImageGranularity,bufferImageGranularity>> feature in terms of "aliasing", and clarify that it applies to bindings in the same memory object (public issue 90). * Clarify the relationship of the slink:VkPhysicalDeviceLimits pname:maxViewportDimensions and pname:viewportBoundsRange limits (public issue 92). * Specify sparse unbound texture replacement in the <<textures-texel-replacement,Texel Replacement>> section independently of robust buffer access language (public issue 100). * Add the <<fundamentals-architecture-model,Architecture Model>> section to explain architecture constraints Vulkan has chosen to accept in order to enable portable and performant code (public issue 122). * State that an object must not be destroyed until *all* (not *any*) uses of that object have completed (public issue 123). * Minor editorial cleanup (public issues 129, 134, 146, 148). * Add validity language for layer and extension names to slink:VkDeviceCreateInfo matching that used for slink:VkInstanceCreateInfo (public issue 130). * Clean up terminology for the case when the bits set in one bitmask are a subset of the bits set in another bitmask (public issue 138). * Document that input attachments are UniformConstant not Input, in the <<interfaces-inputattachment,Fragment Input Attachment Interface>> section (public glslang bug 169). Internal Issues: * Add max enum values to "flag bits" enums (internal issue #136). * Clarify language around the various uses of the term "block" in the <<appendix-compressedtex-bc,Block Compressed Image Formats>> section (internal issue #202). * Removed "expand" dependency from <enums> groups in vk.xml and added auto-generation code in the scripts to infer it instead, to ensure consistency. This caused renaming of sname:VkColorSpaceKHR and sname:VkPresentModeKHR etext:BEGIN_RANGE (etc.) tokens, but those tokens are metadata, not part of the API, and the Vulkan WG is OK with this change. This change adds ranges to two additional enums that were missing them due to not defining the "expand" attribute (internal issue 217). * Tweak makefile to generate ref page nroff (.3) files in the right output directory, working around an a2x limitation (internal issue 223). Other Commits: * Add validity requirements for flink:vkCmdCopyQueryPoolResults pname:dstBuffer parameter. * Fix ref page build to generate .3 targets in the right output directory.

* pname:flags is reserved for future use.
* pname:pipelineBindPoint is a elink:VkPipelineBindPoint value specifying
whether this is a compute or graphics subpass. Currently, only graphics
subpasses are supported.
* pname:inputAttachmentCount is the number of input attachments.
* pname:pInputAttachments is an array of slink:VkAttachmentReference
structures (defined below) that lists which of the render pass's
attachments can: be read in the shader during the subpass, and what
layout the attachment images will be in during the subpass. Each element
of the array corresponds to an input attachment unit number in the
shader, i.e. if the shader declares an input variable
`layout(input_attachment_index=X, set=Y, binding=Z)` then it uses the
attachment provided in pname:pInputAttachments[X]. Input attachments
must: also be bound to the pipeline with a descriptor set, with the
input attachment descriptor written in the location (set=Y, binding=Z).
* pname:colorAttachmentCount is the number of color attachments.
* pname:pColorAttachments is an array of pname:colorAttachmentCount
slink:VkAttachmentReference structures that lists which of the render
pass's attachments will be used as color attachments in the subpass, and
what layout the attachment images will be in during the subpass. Each
element of the array corresponds to a fragment shader output location,
i.e. if the shader declared an output variable `layout(location=X)` then
it uses the attachment provided in pname:pColorAttachments[X].
* pname:pResolveAttachments is `NULL` or a pointer to an array of
slink:VkAttachmentReference structures. If pname:pResolveAttachments is
not `NULL`, each of its elements corresponds to a color attachment (the
element in pname:pColorAttachments at the same index). At the end of
each subpass, the subpass's color attachments are resolved to
corresponding resolve attachments, unless the resolve attachment index
is ename:VK_ATTACHMENT_UNUSED or pname:pResolveAttachments is `NULL`. If
the first use of an attachment in a render pass is as a resolve
attachment, then the pname:loadOp is effectively ignored as the resolve
is guaranteed to overwrite all pixels in the render area.
* pname:pDepthStencilAttachment is a pointer to a
slink:VkAttachmentReference specifying which attachment will be used for
depth/stencil data and the layout it will be in during the subpass.
Setting the attachment index to ename:VK_ATTACHMENT_UNUSED or leaving
this pointer as `NULL` indicates that no depth/stencil attachment will
be used in the subpass.
* pname:preserveAttachmentCount is the number of preserved attachments.
* pname:pPreserveAttachments is an array of pname:preserveAttachmentCount
render pass attachment indices describing the attachments that
are not used by a subpass, but whose contents must: be preserved
throughout the subpass.

The contents of an attachment within the render area become undefined at
the start of a subpass S if all of the following conditions are true:
* The attachment is used as a color, depth/stencil, or resolve attachment
in any subpass in the render pass.
* There is a subpass S1 that uses or preserves the attachment, and a
subpass dependency from S1 to S.
* The attachment is not used or preserved in subpass S.
Once the contents of an attachment become undefined in subpass S, they
remain undefined for subpasses in subpass dependency chains starting with
subpass S until they are written again. However, they remain valid for
subpasses in other subpass dependency chains starting with subpass S1 if
those subpasses use or preserve the attachment.

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).
