* 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
specification source copyright.
* 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).
