Change log for September 5, 2017 Vulkan 1.0.60 spec update:
* Bump API patch number and header version number to 60 for this update.
Github Issues:
* Document that <<queries-timestamps, Timestamp Queries>> can only be
meaningfully compared when they are written from the same queue (public
issue 216).
* Document that the `<extension>` tag `type` attribute is required for
non-disabled extensions (derived from, but does not close public issue
354).
* Clean up registry schema length attribute descriptions to be consistent
and correct (public issue 555).
Internal Issues:
* Replace as much of the hand-written extension appendix metadata as
possible with asciidoc includes generated from corresponding attributes
of +vk.xml+, and enhance the style guide to match. This avoids
inconsistencies between +vk.xml+ and the appendices, and produces a more
uniform style (internal issue 137).
* Remove the generated extDependency.{py,sh} files from the tree and
create them dynamically on demand instead, reducing merge conflicts
(internal issue 713).
* Add a prototype tool for generating in-place difference markup for
sections guarded by asciidoc conditionals, and new syntax for open
blocks to support it (internal issue 833).
* Remove unnecessary restriction of etext:*SYNC_FD_BIT_KHR external handle
types to the same physical device in the
slink:VkPhysicalDeviceIDPropertiesKHR,
flink:VkImportMemoryWin32HandleInfoKHR,
slink:VkImportFenceWin32HandleInfoKHR, slink:VkImportFenceFdInfoKHR,
slink:VkImportSemaphoreWin32HandleInfoKHR,
slink:VkImportSemaphoreFdInfoKHR
<<external-memory-handle-types-compatibility, External memory handle
types compatibility>>, <<external-semaphore-handle-types-compatibility,
External semaphore handle types compatibility>>, and
<<external-fence-handle-types-compatibility, External fence handle types
compatibility>> sections (internal issue 956).
Other Issues:
* Remove dependency of +VK_KHX_device_group+ on +VK_KHR_swapchain+ (there
is an interaction, but not a strict dependency), and add a new
`extension` attribute to the `<require` XML tag to allow classifying a
subset of interfaces of an extension as requiring another extension.
Update the registry schema and documentation accordingly.
New Extensions:
* `VK_AMD_shader_fragment_mask` (and related `GL_AMD_shader_fragment_mask`
GLSL extension)
* `VK_EXT_sample_locations`
* `VK_EXT_validation_cache`

Change log for January 23, 2017 Vulkan 1.0.39 spec update:
* Bump API patch number and header version number to 39 for this update.
Github Issues:
* Clarified that only accesses via the specified buffer/image subresource
ranges are included in the access scopes (public issue 306).
* Add missing valid usage statements for flink:vkCreateComputePipelines
and flink:vkCreateGraphicsPipelines (public issue 427).
Internal Issues:
* Add a Note to the <<invariance,Invariance>> appendix about a difference
between OpenGL and Vulkan with regards to how primitives derived from
offsets are handled (internal issue 355).
* Add the +<<VK_KHR_get_physical_device_properties2>>+,
+<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+
extensions (internal issue 448).
* Add the +<<VK_EXT_shader_subgroup_vote>>+ and
+<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449).
* Update the texture level-of-detail equation in the
<<textures-scale-factor,Scale Factor Operation>> section to better
approximate the ellipse major and minor axes (internal issue 547).
* Forbid non-explicitly allowed uses of interface decorations in the
introduction to the <<interfaces,Shader Interfaces>> chapter (internal
issue 607).
* Replace use of MathJax with KaTeX, for improved load-time performance as
well as avoiding the scrolling-and-scrolling behavior due to MathJax
asynchronous rendering when loading at an anchor inside the spec. This
change also requires moving to HTML5 output for the spec instead of
XHTML, and there is a visible difference in that the chapter navigation
index is now in a scrollable sidebar instead of at the top of the
document. We may or may not retain the nav sidebar based on feedback
(internal issue 613).
* Improve consistency of markup and formatting in extension appendices
(internal issue 631).
Other Issues:
* Add explicit valid usage statements to slink:VkImageCopy requiring that
the source and destination layer ranges be contained in their respective
source and destination images.
* Add valid usage language for swapchain of flink:vkAcquireNextImage. If
the swapchain has been replaced, then it should not be passed to
flink:vkAcquireNextImage.
* Add a valid usage statement to flink:vkCreateImageView, that the image
must have been created with an appropriate usage bit set.
* Noted that slink:VkDisplayPresentInfoKHR is a valid extension of
slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section.
* Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor
to account for the multiple viewport feature. If the feature is not
enabled, the parameters for these functions have required values that
are defined in the <<features-features-multiViewport,multiple
viewports>> section of the spec but were not reflected in the valid
usage text for these functions.
* Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common
color spaces.

Change log for January 5, 2018 Vulkan 1.0.67 spec update:
* 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`

signaled at vsync that the application can wait on?
|
|
|
|
|
|
|
|
*RESOLVED*: A fence.
|
|
|
|
A separate API could later be provided that allows exporting the fence to a
|
|
|
|
native object that could be inserted into standard run loops on POSIX and
|
|
|
|
Windows systems.
|
|
|
|
|
|
|
|
2) Should callbacks be added for a vsync event, or in general to monitor
|
|
|
|
events in Vulkan?
|
|
|
|
|
|
|
|
*RESOLVED*: No, fences should be used.
|
|
|
|
Some events are generated by interrupts which are managed in the kernel.
|
|
|
|
In order to use a callback provided by the application, drivers would need
|
|
|
|
to have the userspace driver spawn threads that would wait on the kernel
|
|
|
|
event, and hence the callbacks could be difficult for the application to
|
|
|
|
synchronize with its other work given they would arrive on a foreign thread.
|
|
|
|
|
|
|
|
3) Should vblank or scanline events be exposed?
|
|
|
|
|
|
|
|
*RESOLVED*: Vblank events.
|
|
|
|
Scanline events could be added by a separate extension, but the latency of
|
|
|
|
processing an interrupt and waking up a userspace event is high enough that
|
|
|
|
the accuracy of a scanline event would be rather low.
|
|
|
|
Further, per-scanline interrupts are not supported by all hardware.
