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 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.

*Overview*::
|
|
|
|
|
|
|
|
|
|
+VK_KHR_maintenance1+ adds a collection of minor features that were
|
|
|
|
|
intentionally left out or overlooked from the original Vulkan 1.0 release.
|
|
|
|
|
|
|
|
|
|
The new features are as follows:
|
|
|
|
|
|
|
|
|
|
* Allow 2D and 2D array image views to be created from 3D images, which
|
|
|
|
|
can then be used as color framebuffer attachments.
|
|
|
|
|
This allows applications to render to slices of a 3D image.
|
|
|
|
|
* Support flink:vkCmdCopyImage between 2D array layers and 3D slices.
|
|
|
|
|
This extension allows copying from layers of a 2D array image to slices
|
|
|
|
|
of a 3D image and vice versa.
|
|
|
|
|
* Allow negative height to be specified in the
|
|
|
|
|
slink::VkViewport::pname:height field to perform y-inversion of the
|
|
|
|
|
clip-space to framebuffer-space transform.
|
|
|
|
|
This allows apps to avoid having to use gl_Position.y = -gl_Position.y
|
|
|
|
|
in shaders also targeting other APIs.
|
|
|
|
|
* Allow implementations to express support for doing just transfers and
|
|
|
|
|
clears of image formats that they otherwise support no other format
|
|
|
|
|
features for.
|
|
|
|
|
This is done by adding new format feature flags
|
|
|
|
|
ename:VK_FORMAT_FEATURE_TRANSFER_SRC_BIT_KHR and
|
|
|
|
|
ename:VK_FORMAT_FEATURE_TRANSFER_DST_BIT_KHR.
|
|
|
|
|
* Support flink:vkCmdFillBuffer on transfer-only queues.
|
|
|
|
|
Previously flink:vkCmdFillBuffer was defined to only work on command
|
|
|
|
|
buffers allocated from command pools which support graphics or compute
|
|
|
|
|
queues.
|
|
|
|
|
It is now allowed on queues that just support transfer operations.
|
|
|
|
|
* Fix the inconsistency of how error conditions are returned between the
|
|
|
|
|
flink:vkCreateGraphicsPipelines and flink:vkCreateComputePipelines
|
|
|
|
|
functions and the flink:vkAllocateDescriptorSets and
|
|
|
|
|
flink:vkAllocateCommandBuffers functions.
|
|
|
|
|
* Add new ename:VK_ERROR_OUT_OF_POOL_MEMORY_KHR error so implementations
|
|
|
|
|
can give a more precise reason for flink:vkAllocateDescriptorSets
|
|
|
|
|
failures.
|
|
|
|
|
* Add a new command flink:vkTrimCommandPoolKHR which gives the
|
|
|
|
|
implementation an opportunity to release any unused command pool memory
|
|
|
|
|
back to the system.
