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`

This device extension extends slink:vkQueuePresentKHR, from the
|
|
|
|
|
+VK_KHR_swapchain+ extension, allowing an application to specify a list of
|
|
|
|
|
rectangular, modified regions of each image to present.
|
|
|
|
|
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.
