* Bump API patch number and header version number to 61 for this update.
Github Issues:
* Provide alternate length attributes (altlen=) in the XML schema, for
those using length attributes to generate code instead of documentation
(public issue 555).
* Fix erroneous references to `latex:` being used for asciidoc math
markup, rather than `latexmath:` (public pull request 556).
* Add author ID to XML for Kazan software renderer (public pull request
557).
Internal Issues:
* Add the <<fundamentals-abi,Application Binary Interface>> section
describing platform ABI requirements and recommendations, add examples
of function and function pointer declarations to the
<<boilerplate-platform-specific-calling-conventions, Platform-Specific
Calling Conventions>> section, and remove related language that existed
elsewhere in the specification (internal issue 64).
* Describe where to document valid usage interactions of chained
structures in the style guide, and fix one case now appearing in
slink:VkBufferCreateInfo instead of the child
slink:VkDedicatedAllocationBufferCreateInfoNV structure (internal issue
715).
* Add example to the style guide of describing enumerated types which are
empty when the spec is built without relevant extensions enabled, and
apply it to existing examples for
elink:VkDescriptorSetLayoutCreateFlagBits and
elink:VkSubpassDescriptionFlagBits (internal issue 864).
* Add a note to the <<fundamentals-validusage-enums, Valid Usage for
Enumerated Types>> section that the special values suffixed with
etext:_BEGIN_RANGE, etext:_END_RANGE, etext:_RANGE_SIZE and
etext:_MAX_ENUM are not part of the API and should: not be used by
applications (internal issue 872).
* Added note to flink:vkCmdUpdateBuffers explaining the performance
penalty for copies done in this way, and why the upper copy limit is
what it is (internal issue 952).
* Update `VK_KHX_device_group` to split some functionality into the new
`VK_KHR_bind_memory2` extension, and rename that functionality (internal
issue 969).
* Remove *Status* fields from extension appendices, since they are by
definition published and complete by the time they reach the public
github repository (internal issue 973).
Other Issues:
* Update Data Format specification dependency to version 1.2 and change
references to DF sections accordingly.
* Update XML to make the pname:pAllocator parameter of
flink:vkRegisterDeviceEventEXT and flink:vkRegisterDisplayEventEXT in
the `VK_EXT_display_control` extension as optional.
New Extensions:
* `VK_KHR_bind_memory2`
* `VK_KHR_image_format_list`
* `VK_KHR_maintenance2`
* `VK_KHR_sampler_ycbcr_conversion`

+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.
