Change log for March 5, 2018 Vulkan 1.1.72 spec update: * Update release number to 72. Github Issues: * Restructure the repository to put the specification `Makefile` and associated spec source material at the top level, `vk.xml` and associated scripts material in `xml/`, and generated include and source files in `include/vulkan/` and `src/ext_loader/`, respectively (public issue 436). * Add missing bullet point markup to flink:vkCmdCopyImage valid usage statement, so it gets a VUID assigned (public issue 627). * Fix broken links in a couple of extension appendices (public pull request 665). * Add the \<platform> tag to the index in section 4.1 of the registry schema documentation, and add the protect= attribute of \<extension> tags to the comments in `registry.rnc` (public issues 673, 678). * Add missing valid usage statements for sparse image interactions to flink:VkImageCreateInfo (public pull request 675). * Fix improper usage and grammar of "`can: not`" (public pull request 681). * Remove duplicate spec language and NOTE on present layout between the flink:vkAcquireNextImageKHR and flink:vkAcquireNextImage2KHR commands (public pull request 685). * Fix some typos and markup issues (public pull request 689; public issues 642, 667, 687). * Fix typo etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT -> ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT in the <<external-semaphore-handle-types-compatibility, External semaphore handle types compatibility>> table (public pull request 691). Internal Issues: * Remove the need for the "`noautovalidity`" attribute on extension structures in `vk.xml`. It is now implied by the "`structextends`" attribute instead (internal issue 942). * Replace uses of "`currently bound`" with "`bound`", since "`currently`" is redundant and distracting, and add a corresponding rule to the style guide (internal issue 993). * Fixed subtle issues with the last updates to flink:vkAcquireNextImageKHR language that had resulted in ambiguities (internal issue 1178). * Make it clear that only one query of a given type is allowed at a time by reordering valid usage statements for flink:vkCmdBeginQuery and flink:vkCmdEndQuery, and removing redundant ones (internal issue 1213). * Swapped OL1 and OL3 in `tessparamUL.svg` to match previous version, and fixed where "`(no edge)`" appears (internal issue 1215). Other Issues: * Fixed a minor problem with the valid usage statement extraction script, and corresponding markup in the spec source. New Extensions: * `VK_AMD_shader_core_properties` * `VK_EXT_descriptor_indexing` * `VK_NV_shader_subgroup_partitioned`

This extension enables support for a new class of subgroup operations via
the
https://github.com/KhronosGroup/GLSL/blob/master/extensions/nv/GL_NV_shader_subgroup_partitioned.txt[+GL_NV_shader_subgroup_partitioned+]
GLSL extension and
https://www.khronos.org/registry/spir-v/extensions/NV/SPV_NV_shader_subgroup_partitioned.html[+SPV_NV_shader_subgroup_partitioned+]
SPIR-V extension.
Support for these new operations is advertised via the
elink:VK_SUBGROUP_FEATURE_PARTITIONED_BIT_NV bit.
This extension requires Vulkan 1.1, for general subgroup support.
