* Bump API patch number and header version number to 22 for this update.
Github Issues:
* Translate the subpass self-dependency language into concrete
validity statements, and added a validity statement about the
restrictions on layout parameters (public issue 267).
* Add validity requirement that
slink:VkAttachmentDescription::pname:finalLayout and
slink:VkAttachmentReference::pname:layout must not be
ename:VK_IMAGE_LAYOUT_UNDEFINED or
ename:VK_IMAGE_LAYOUT_PREINITIALIZED (public issue 268).
* Clarify that slink:VkSubpassDescription::pname:pResolveAttachments
layouts are used. Make language consistent with other attachment
arrays (public issue 270).
* Changed 64-bit definition for
dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE to work for x32 platform in
+vk.xml+ and the resulting +vulkan.h+ (public issue 282).
* Add missing error return code for
flink:vkEnumerateInstanceExtensionProperties and
flink:vkEnumerateDeviceExtensionProperties (public issue 285)
* Fix several cases of stext::VkStructName.memberName markup to
stext::VkStructName::pname:memberName, to match other usage in the
spec, and describe this markup in the style guide (public issue
286).
* Modified validity language generation script to avoid redundant
common ancestor language if covered by generic parent language, and
used `Both' instead of `Each' when appropriate (public issue 288).
Internal Issues:
* Add language about behavior of flink:vkAllocateDescriptorSets when
allocation fails due to fragmentation, a new error
ename:VK_ERROR_FRAGMENTED_POOL, and a Note explaining the situation
(internal issue 309).
* For the features of code:PointSize, code:ClipDistance, and
code:CullDistance, the SPIR-V capability is required to be declared
on use (read or write) rather than on decoration (internal issue
359).
* Have desktop versions of GLSL respect precision qualification
(code:mediump and code:lowp) when compiling for Vulkan. These will
get translated to SPIR-V's code:RelaxedPrecision decoration as they
do with OpenGL ES versions of GLSL (ESSL). The default precision of
all types is code:highp when using a desktop version (internal issue
360).
* Add validity statement for slink:VkImageCreateInfo specifying that
multisampled images must be two-dimensional, optimally tiled, and
with a single mipmap level (internal issue 369).
* Add validity statements to slink:VkImageViewCreateInfo disallowing
creation of images or image views with no supported features. Made
some slink:VkImageViewCreateInfo validity statements more precise
and consistent. Added a Note to the <<features,features>> chapter
about formats with no features (internal issue 371).
* Remove +manpages+ from default build targets. Nroff outputs
containing imbedded latexmath will not render properly. Fixing this
is a lot of work for limited use cases (internal issue 401).
Other Commits:
* Fix flink:vkRenderPassBeginInfo::pname:clearValueCount validity
statement to be based on attachment indices rather than the number
of cleared attachments
(Vulkan-LoaderAndValidationLayers/issues/601).
* Convert registry documentation from LaTeX to asciidoc source and
rename from +src/spec/readme.tex+ to +src/spec/registry.txt+.
* Fix lack of Oxford commas in validity language.
* Lots of cleanup of generator scripts and Makefiles to move extension
list for generator into the script arguments instead of the body of
genvk.py, and express better dependencies between XML, scripts, and
generated files.

Members
|
|
-------
|
|
|
|
* pname:residencyStandard2DBlockShape is ename:VK_TRUE if the physical
|
|
device will access all single-sample 2D sparse resources using the
|
|
standard sparse image block shapes (based on image format), as described
|
|
in the <<sparsememory-sparseblockshapessingle,Standard Sparse Image Block
|
|
Shapes (Single Sample)>> table. If this property is not supported the
|
|
value returned in the pname:imageGranularity member of the
|
|
sname:VkSparseImageFormatProperties structure for single-sample 2D
|
|
images is not required: to match the standard sparse image block
|
|
dimensions listed in the table.
|
|
* pname:residencyStandard2DMultisampleBlockShape is ename:VK_TRUE if the
|
|
physical device will access all multisample 2D sparse resources using
|
|
the standard sparse image block shapes (based on image format), as
|
|
described in the <<sparsememory-sparseblockshapesmsaa,Standard Sparse
|
|
Image Block Shapes (MSAA)>> table. If this property is not supported, the
|
|
value returned in the pname:imageGranularity member of the
|
|
sname:VkSparseImageFormatProperties structure for multisample 2D images
|
|
is not required: to match the standard sparse image block dimensions
|
|
listed in the table.
|
|
* pname:residencyStandard3DBlockShape is ename:VK_TRUE if the physical
|
|
device will access all 3D sparse resources using the standard sparse image
|
|
block shapes (based on image format), as described in the
|
|
<<sparsememory-sparseblockshapessingle,Standard Sparse Image Block
|
|
Shapes (Single Sample)>> table. If this property is not supported, the
|
|
value returned in the pname:imageGranularity member of the
|
|
sname:VkSparseImageFormatProperties structure for 3D images is not
|
|
required: to match the standard sparse image block dimensions listed in
|
|
the table.
|
|
* pname:residencyAlignedMipSize is ename:VK_TRUE if images with mip level
|
|
dimensions that are not integer multiples of the corresponding dimensions
|
|
of the sparse image block may: be placed in the mip tail. If this property
|
|
is not reported, only mip levels with dimensions smaller than the
|
|
pname:imageGranularity member of the sname:VkSparseImageFormatProperties
|
|
structure will be placed in the mip tail. If this property is reported the
|
|
implementation is allowed to return
|
|
ename:VK_SPARSE_IMAGE_FORMAT_ALIGNED_MIP_SIZE_BIT in the pname:flags
|
|
member of sname:VkSparseImageFormatProperties, indicating that mip level
|
|
dimensions that are not integer multiples of the corresponding dimensions
|
|
of the sparse image block will be placed in the mip tail.
|
|
* pname:residencyNonResidentStrict specifies whether the physical device
|
|
can: consistently access non-resident regions of a resource. If this
|
|
property is ename:VK_TRUE, access to non-resident regions of resources
|
|
will be guaranteed to return values as if the resource were populated
|
|
with 0; writes to non-resident regions will be discarded.
