* 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).
* 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.
