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.

Change log for July 22, 2016 Vulkan 1.0.22 spec update: * 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.

If multiple sname:VkDescriptorPoolSize structures appear in the
pname:pPoolSizes array then the pool will be created with enough storage
for the total number of descriptors of each type.
Fragmentation of a descriptor pool is possible and may: lead to descriptor
set allocation failures. A failure due to fragmentation is defined as
failing a descriptor set allocation despite the sum of all outstanding
descriptor set allocations from the pool plus the requested allocation
requiring no more than the total number of descriptors requested at pool
creation. Implementations provide certain guarantees of when fragmentation
mustnot: cause allocation failure, as described below.
If a descriptor pool has not had any descriptor sets freed since it was
created or most recently reset then fragmentation mustnot: cause an
allocation failure (note that this is always the case for a pool created
without the ename:VK_DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT bit
set). Additionally, if all sets allocated from the pool since it was created
or most recently reset use the same number of descriptors (of each type) and
the requested allocation also uses that same number of descriptors (of each
type), then fragmentation mustnot: cause an allocation failure.
If an allocation failure occurs due to fragmentation, an application can:
create an additional descriptor pool to perform further descriptor set
allocations.

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.

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).
