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`

Change log for June 24, 2017 Vulkan 1.0.53 spec update:
* Bump API patch number and header version number to 53 for this update.
Github Issues:
Internal Issues:
* Clarify mappings of coordinates for mutable, compatible image views in
slink:VkImageViewCreateInfo (internal issue 815).
* Make ename:VK_BIND_SFR_BIT require a logical device with multiple
physical devices, so that standard sparse image block dimensions are
only required on systems that support multi-GPU (internal issue 835).
* Convert all files from use of // refBegin .. // refEnd comments to
delimit ref pages, to use of open blocks, and update style guide
accordingly (internal issue 839).
* Add valid usage for slink:VkWriteDescriptorSet when performing updates
to a ename:VK_STORAGE_IMAGE descriptor with layout
ename:VK_IMAGE_LAYOUT_GENERAL.
* Add a hack to the validity generator script to support an odd
interaction between flink:vkCmdFillBuffer and an extension (internal
issue 853).
* Remove redundant text describing slink:VkBufferCreateInfo::pname:usage,
which was already covered by implicit valid usage (internal issue 854).
* Update implicit validity generator script to properly handle the
pname:sType and pname:pNext members of "returnedonly" structures
(internal issue 874).
* Note that slink:VkApplicationInfo::pname:pApplicationName &
slink:VkApplicationInfo::pname:pEngineName are optional, and add missing
implicit valid usage statements for flink:vkDestroyInstance.
* Added missing valid usage for flink:vkCmdWriteTimestamp to require a
timestamp query pool.
* Simplify and/or split "`non-atomic`" valid usage statements.
New Extensions:
* `VK_AMD_gpu_shader_int16`
* `VK_EXT_blend_operation_advanced`
* `VK_EXT_sampler_filter_minmax`
* `VK_NV_framebuffer_mixed_samples`
-----------------------------------------------------
Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release
combines both change sets.
-----------------------------------------------------
Change log for June 13, 2017 Vulkan 1.0.52 spec update:
* Bump API patch number and header version number to 52 for this update.
Github Issues:
Internal Issues:
* Clarify behavior when non-coherent memory has
<<memory-device-unmap-does-not-flush, not been flushed before being
unmapped>> (internal issue 819).
* Fix description of code:WorkgroupSize builtin to note it decorates an
object, not a variable (internal issue 836).
* Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style
equations are rendered properly (internal issue 845).
* Add language to the "`Extension Handles, Objects, Enums, and Typedefs`"
section of the Procedures and Conventions document stating that any new
handle type requires a corresponding entry in the elink:VkObjectType
enumerated type (internal issue 856).
* Update style guide to use slink macro for Vulkan handle type names, and
define narrow conditions under which to use the *name and *text macros
instead of *link (internal issue 886).
* Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>>
extension on VK_KHX_device_group_creation to +vk.xml+ and the extension
appendix.
* Change the copyright on Vulkan specification asciidoc *source* files to
CC-BY 4.0, and update the proprietary Khronos copyright applied to the
generated *output* formats (internal issue 327). This enables broader
re-use and modification of the Vulkan specification sources, while not
affecting the Reciprocal IP License between Vulkan Adopters and Working
Group Members.
New Extensions:
* `VK_NV_fill_rectangle`
* `VK_NV_fragment_coverage_to_color`

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`

`<<VK_KHR_swapchain>>` extension, allowing an application to specify a list
|
|
|
|
|
of rectangular, modified regions of each image to present.
|
2017-03-31 23:06:31 +00:00
|
|
|
This should be used in situations where an application is only changing a
|
|
|
|
|
small portion of the presentable images within a swapchain, since it enables
|
|
|
|
|
the presentation engine to avoid wasting time presenting parts of the
|
|
|
|
|
surface that haven't changed.
|
|
|
|
|
|
|
|
|
|
This extension is leveraged from the +EGL_KHR_swap_buffers_with_damage+
|
|
|
|
|
extension.

=== Issues
|
|
|
|
|
|
|
|
|
|
1) How should we handle steroescopic-3D swapchains? We need to add a layer
|
|
|
|
|
for each rectangle.
|
|
|
|
|
One approach is to create another struct that contains the slink:VkRect2D
|
|
|
|
|
plus layer, and have slink:VkPresentRegionsKHR point to an array of that
|
|
|
|
|
struct.
|
2017-11-08 23:09:27 +00:00
|
|
|
Another approach is to have two parallel arrays, ptext:pRectangles and
|
|
|
|
|
ptext:pLayers, where ptext:pRectangles[i] and ptext:pLayers[i] must be used
|
|
|
|
|
together.
|
2017-03-31 23:06:31 +00:00
|
|
|
Which approach should we use, and if the array of a new structure, what
|
|
|
|
|
should that be called?
|
|
|
|
|
|
|
|
|
|
*RESOLVED*: Create a new structure, which is a slink:VkRect2D plus a layer,
|
|
|
|
|
and will be called slink:VkRectLayerKHR.
|
|
|
|
|
|
|
|
|
|
2) Where is the origin of the slink:VkRectLayerKHR?
|
|
|
|
|
|
|
|
|
|
*RESOLVED*: The upper left corner of the presentable image(s) of the
|
|
|
|
|
swapchain, per the definition of framebuffer coordinates.
|
|
|
|
|
|
|
|
|
|
3) Does the rectangular region, slink:VkRectLayerKHR, specify pixels of the
|
|
|
|
|
swapchain's image(s), or of the surface?
|
|
|
|
|
|
|
|
|
|
*RESOLVED*: Of the image(s).
|
|
|
|
|
Some presentation engines may scale the pixels of a swapchain's image(s) to
|
|
|
|
|
the size of the surface.
|
|
|
|
|
The size of the swapchain's image(s) will be consistent, where the size of
|
|
|
|
|
the surface may vary over time.
|
|
|
|
|
|
|
|
|
|
4) What if all of the rectangles for a given swapchain contain a width
|
|
|
|
|
and/or height of zero?
|
|
|
|
|
|
|
|
|
|
*RESOLVED*: The application is indicating that no pixels changed since the
|
|
|
|
|
last present.
|
|
|
|
|
The presentation engine may use such a hint and not update any pixels for
|
|
|
|
|
the swapchain.
|
|
|
|
|
However, all other semantics of flink:vkQueuePresentKHR must still be
|
|
|
|
|
honored, including waiting for semaphores to signal.
