* 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).
* 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.
* Bump API patch number and header version number to 14 for this
update.
Github Issues:
* Fix validity language for sname:VkCommandBufferAllocateInfo to
impose range limits on pname:commandBufferCount (public issue 178).
* Fix validity language for flink:vkCmdExecuteCommands to refer to the
correct structure names (public issue 179).
* Fix two copy-and-paste errors in the WSI queries, where the wrong
term was used for what was being returned (public issue 206).
* Add a note in the documentation of
flink:vkGetPhysicalDeviceSurfaceFormatsKHR, about what it means if
ename:VK_FORMAT_UNDEFINED is returned (public issue 207).
Internal Issues:
* Clarify the usage and correct the name for the bitmask referenced in
<<queries-pipestats,Pipeline Statistics Queries>> (internal issue
334).
Other Commits:
* Fix the names of decorations listed in the
<<interfaces-builtin-variables,Built-in Variables>> section such
that they match the SPIR-V specification.
* Bump API patch number and header version number to 9 for this
update.
Github Issues:
* Fix memory type preorder definition and clarify example list and source
code for slink:VkMemoryRequirements and slink:VkMemoryHeap (public issue
26).
* Ensure slink:VkAllocationCallbacks are properly defined (public issue
73).
* Clarify the WSI extension language by switching from the fuzzier
"ownership" language to more-consistent "acquire" language (public issue
117).
* Add language allowing allocation and freeing of memory scoped to the
duration of any API command in the <<memory-allocation,Memory
Allocation>> section (public issue 136).
* Clarify the explicit location assignment always overrides the inherited
location in the <<interfaces-iointerfaces-locations,Location
Assignment>> section, even for the first member of a block (public issue
141).
* Fixed references to
slink:VkCommandBufferInheritanceInfo::pname:pipelineStatistics (public
issue 158).
* Fix name of slink:VkBufferCopy::pname:size field in validity language
for flink:vkCmdCopyBuffer (public issue 162).
Internal Issues:
* Update GL_KHR_vulkan_glsl specification to clarify disallowance of
spec-const arrays in initializers (internal issue 248).
* Clarify <<interfaces-iointerfaces-matching,Interface Matching>> section
to state that user-defined variable interface must match too (internal
issue 250).
* 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
<<interfaces-iointerfaces-locations,Location Assignment>>
section (public issue 45).
* Editorial fixes for <<commandbuffer-allocation,Command Buffer
Allocation>> section (public issues 54, 59).
* Clarify behavior of depth test in the <<fragops-depth,Depth
Test>> 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 <<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 <<fig-non-strict-lines,Non
strict lines>> diagram. Use more easily distinguished symbols in
tables in the <<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
<<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 #197).
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.
* 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.
