* Bump API patch number and header version number to 67 for this update. * Update copyright dates to 2018 Github Issues: * Fix texture lookup functions in `GL_KHR_vulkan_glsl` specification (public pull request 363). * Clarify the state waited semaphores are left in when a call to flink:vkQueuePresentKHR fails (public issue 572). * Cleanup descriptions of slink:VkObjectTablePushConstantEntryNVX and slink:VkObjectTableDescriptorSetEntryNVX (public issue 583) * Remove redundant flink:vkCmdSetDiscardRectangleEXT valid usage statements (public pull 586). * Make dynamic state array length valid usage statements implicit for flink:vkCmdSetViewportWScalingNV, flink:vkCmdSetDiscardRectangleEXT, and flink:vkCmdSetViewport (public pull 589). * Clarify meaning of window extent (0,0) in slink:VkSwapchainKHR for the Windows and X11 platforms, in their respective extensions (public issue 590). * Allow flink:vkGetPastPresentationTimingGOOGLE to return ename:VK_INCOMPLETE (public issue 604). * Add synchronization valid usage statements to flink:vkAcquireNextImage (public pull 611). * Fix some broken external links and internal xrefs (public pull 613). * Clean up slink:VkViewport valid usage statements in the presence or absence of relevant extensions (public pull 623). * Remove ename:VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_STENCIL_ATTACHMENT_OPTIMAL_KHR token from VK_KHR_maintenance2 from the non-extension VU path for slink:VkGraphicsPipelineCreateInfo (public issue 628). * Miscellaneous minor markup fixes - extension name strings (public pull 631), Notes (pull 633), queue names emitted by generator scripts (pull 634), block formatting in slink:VkDescriptorUpdateTemplateEntryKHR (pull 635), ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_CUBIC_BIT_IMG (pull 641), quotes and apostrophes (pull 643), * Miscellaneous minor grammar fixes (public pull 644). * Fix markup macros so usage like ptext:*Src* works (public pull 647). Internal Issues: * Clarify in the `VK_KHR_surface` and `VK_KHR_swapchain` extensions that parameter combinations which aren't supported for normal images are also unsupported for presentable images, even if the parameter values are individually supported as reported by the surface capability queries (internal issue 1029). * Fixed XML typo in the valid value field of the pname:sType member of slink:VkPhysicalDeviceExternalMemoryHostPropertiesEXT (internal issue 1100). Other Issues: * Add memory semantics validity rules to the <<spirvenv-module-validation, Validation Rules within a Module>> section of the SPIR-V environment appendix, and specify that sequentiality consistency is not supported. This forbids certain cases like "`Load+Release`" that we don't expect to ever be meaningful. * Document mapping of OpenGL Shading Language barriers to SPIR-V scope and semantics in the `GL_KHR_vulkan_glsl` specification. New Extensions: * `VK_EXT_conservative_rasterization`
HTML Diff Script for Vulkan
This is a first cut at a script to compare Vulkan HTML specifications. Usage is simply 'htmldiff file1.html file2.html > diff.html'. The script does not copy CSS and images requires by the input specs, so it's best to generate the output in the same directory as one of the inputs.
The scripts used require Python and Perl. Additionally, the python 'utidylib' module and the underlying libtidy C library are required, which may make it challenging to run the scripts on non-Linux platforms
- I haven't checked and those requirements cannot be easily removed. On Debian Linux, it may be necessary to install the 'python-utidylib' and 'libtidy' packages if they are not already present. I haven't checked dependencies for other Linux distributions but they are probably similar.
The scripts are taken from the code backing the
http://services.w3.org/htmldiff
website. 'htmldiff' is the Python driver script. 'htmldiff.pl' is the Perl script which generates the diff after preprocessing of the input HTML by 'htmldiff'. 'htmldiff.orig' is the original Python script from the website, modified to run at the command line instead of as a CGI script.
