* Update release number to 88.
Public Issues:
* Make clear that
tname:PFN_vkDebugUtilsMessengerCallbackEXT::pname:messageTypes is a
bitmask, and correct a typo in the spelling of
slink:VkDebugUtilsMessengerCreateInfoEXT.txt::pname:messageType (public
pull request 800).
* Make an ABI-compatible change of the type of
slink:VkPhysicalDeviceDriverPropertiesKHR::pname:driverID to use the new
elink:VkDriverIdKHR type (public issue 811).
Internal Issues:
* Clarify for the <<features-features-shaderStorageImageExtendedFormats>>
feature and in the <<spirvenv-capabilities-table>> that the feature
means that all of the formats are supported, and that otherwise the
features can be queried per-format (internal issue 1273).
* Clarified interactions of `VK_EXT_external_memory_host` with host cache
management commands and structures flink:vkMapMemory,
flink:vkFlushMappedMemoryRanges, slink:VkMappedMemoryRange, and
flink:vkUnmapMemory using the new glossary term "`Host Mapped Device
Memory`" (internal issue 1385).
* Update the language for flink:vkCreateViSurfaceNN.txt describing the
pname:currentExtent of a VI surface to more accurately reflect current
capabilities, replacing "`undefined`" with more explicit behavior
(internal issue 1410).
New Extensions:
* `VK_EXT_calibrated_timestamps`
* `VK_EXT_image_drm_format_modifier` (this extension was previously
disabled in vk.xml, and has now been enabled after some changes to fix
performance issues).
* `VK_EXT_pci_bus_info`
* `VK_EXT_transform_feedback`
* `VK_GOOGLE_hlsl_functionality1`, exposing support for
`SPV_GOOGLE_hlsl_functionality1`.
* `VK_GOOGLE_decorate_string`, exposing support for
`SPV_GOOGLE_decorate_string`.
* Update release number to 87.
Public Issues:
* Merge flink:vkCmdPipelineBarrier self-dependency barrier VUs referring
to the same subpass dependency (public pull request 756).
* Describe default value of `"optional"` attribute in the registry schema
document (public issue 769)
* Fix links in <<VK_NVX_raytracing>> extension (public pull request 805).
* Mark the <<VK_KHR_mir_surface>> extension obsolete (see public issue 814
- does not close this, however).
* Fix missing endif in Image Creation block (public issue 817).
Internal Issues:
* Clarify that the compressed texture formats corresponding to
<<features-features-textureCompressionETC2>>,
<<features-features-textureCompressionASTC_LDR>>, and
<<features-features-textureCompressionBC>> is not contingent on the
feature bits, and may be supported even if the features are not enabled
(internal issue 663).
* Clarify that code:FragStencilRefEXT is output only in the
<<interfaces-builtin-variables, Built-In Variables>> section (internal
issue 1173).
* Identify and correct many overly-aggressive uses of "`undefined`", and
narrow them down, where straightforward to do so. Mark such resolved
uses of "`undefined`" with the custom undefined: macro. Add a new
<<writing-undefined, Describing Undefined Behavior>> section (internal
issue 1267).
* Don't require code:inline_uniform_block descriptors to be populated
before use in the flink:vkAllocateDescriptorSets section (internal issue
1380).
* Allow suppressing inline SVG images by controlling this with an
attribute set in the Makefile, rather than the explicit [%inline]
directive (internal issue 1391).
* Mark 'Khronos' as a registered trademark in several places, now that it
is one.
* Fix typo in the <<VK_KHR_shader_atomic_int64>> appendix using the GLSL
naming of the compare exchange op when referring to the SPIR-V op.
* Specify in the flink:vkGetPhysicalDeviceQueueFamilyProperties section
that all implementations must support at least one queue family, and
that every queue family must contain at least one queue.
* Make slink:VkPipelineDynamicStateCreateInfo::pname:dynamicStateCount,
slink:VkSampleLocationsInfoEXT::pname:sampleLocationsPerPixel, and
slink:VkSampleLocationsInfoEXT::pname:sampleLocationsCount optional, to
fix bogus implicit valid usage checks that were causing failures in the
conformance tests.
* Fix vendor tag in reserved extension 237 constants. Does not affect
anything since it's just a placeholder, but this should avoid further
comments.
* Minor markup fixes in some extension appendices.
New Extensions:
* `<<VK_FUCHSIA_imagepipe_surface>>`
* Update release number to 86.
Internal Issues:
* Add new <<resources-image-creation-limits, Image Creation Limits>>
section and reference that from valid usage statements, reducing
combinatorial complexity of extension-dependent VUs. Also fixes some
underspecified limits (such as pname:maxMipLevels) in the VUs for
slink:VkImageCreateInfo when
slink:VkExternalMemoryImageCreateInfo::pname:externalMemoryHandles
contains multiple bits, and fixes incorrectly (and underspecified)
limits when an Android external format is used (internal issue 1370).
* Remove unused "`Fragment Area Granularity`" glossary entry accidentally
introduced in the 1.1.85 update.
New Extensions:
* `VK_KHR_driver_properties`
* `VK_KHR_shader_atomic_int64`
* The specification sources contain text for another extension,
`VK_EXT_image_drm_format_modifier`, but this extension is not yet
complete, and is marked disabled in `vk.xml`. The extension will be
enabled, and become part of the spec, only when the authors decide it is
ready.
