* Update release number to 98.
Public Issues:
* Fix missing markup in flink:vkDestroyPipelineLayout valid usage
statement (pull request 882).
* Add missing contributors for `<<VK_EXT_buffer_device_address>>` (public
pull request 891).
Internal Issues:
* Detect nested bullet points in valid usage blocks and warn about them
during VUID assignment (internal issue 1382).
* Update the style guide to document the process for reserving new bits in
bitmask types (internal issue 1411).
* Clarify for slink:VkApplicationInfo::pname:apiVersion and in the
<<fundamentals-validusage-versions, Valid Usage for Newer Core
Versions>> section when it is valid for an application to use a certain
version of Vulkan API functionality (for an instance and for a
device/physical device); and when the validation layers must generate an
error (internal issue 1412).
* Add optional <<memory-model-availability-visibility, transitive
availability/visibility operations to the memory model, including a new
pname:vulkanMemoryModelAvailabilityVisibilityChains feature for
slink:VkPhysicalDeviceVulkanMemoryModelFeaturesKHR (internal issue
1460).
* Add the code:StorageBuffer storage class to those in the
<<interfaces-resources-descset, Descriptor Set Interface>> (internal
issue 1480).
* Add missing `returnedonly` tags for a number of returned extension
structures that can be passed in pname:pNext chains (internal issue
1515).
* Clean up and rearrange some spec language for
slink:VkRenderPassCreateInfo and slink:VkAttachmentReference.txt
(internal issue 1522).
* Correctly round the code:OpVectorTimesScalar and
code:OpMatrixTimesScalar SPIR-V operations in the <<Precision of core
SPIR-V Instructions>> table (internal merge request 2996).
* Work around cases in flink:vkCmdBeginTransformFeedbackEXT,
flink:vkCmdEndTransformFeedbackEXT, and
slink:VkPipelineCoverageModulationStateCreateInfoNV where an array
parameter is `optional` but the length is not in `vk.xml`. This is an
interim fix using `noautovalidity` + handcoded VU replacing those that
should be autogenerated (internal issue 2944 and
https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/480).
* Remove redundant capability validation of the code:float16 and code:int8
SPIR-V capabilities from the <<spirvenv-capabilities, Capabilities>>
section, since they are already covered in the preceding table.
* Update check_spec_links script, including validation for reference page
open blocks. Fix errors identified by the script.

|
This extension provides new entry points to query device display properties
|
|
and capabilities in a way that can be easily extended by other extensions,
|
|
without introducing any further entry points.
|
|
This extension can be considered the <<VK_KHR_display,VK_KHR_display>>
|
|
equivalent of the <<VK_KHR_get_physical_device_properties2,
|
|
VK_KHR_get_physical_device_properties2>> extension.
|
|
|
|
=== New Object Types
|
|
|
|
None.
|
|
|
|
=== New Enum Constants
|
|
|
|
* Extending elink:VkStructureType:
|
|
** ename:VK_STRUCTURE_TYPE_DISPLAY_PROPERTIES_2_KHR
|
|
** ename:VK_STRUCTURE_TYPE_DISPLAY_PLANE_PROPERTIES_2_KHR
|
|
** ename:VK_STRUCTURE_TYPE_DISPLAY_MODE_PROPERTIES_2_KHR
|
|
** ename:VK_STRUCTURE_TYPE_DISPLAY_PLANE_INFO_2_KHR
|
|
** ename:VK_STRUCTURE_TYPE_DISPLAY_PLANE_CAPABILITIES_2_KHR
|
|
|
|
=== New Enums
|
|
|
|
None.
|
|
|
|
=== New Structures
|
|
|
|
* slink:VkDisplayProperties2KHR
|
|
* slink:VkDisplayPlaneProperties2KHR
|
|
* slink:VkDisplayModeProperties2KHR
|
|
* slink:VkDisplayPlaneInfo2KHR
|
|
* slink:VkDisplayPlaneCapabilities2KHR
|
|
|
|
=== New Functions
|
|
|
|
* flink:vkGetPhysicalDeviceDisplayProperties2KHR
|
|
* flink:vkGetPhysicalDeviceDisplayPlaneProperties2KHR
|
|
* flink:vkGetDisplayModeProperties2KHR
|
|
* flink:vkGetDisplayPlaneCapabilities2KHR
|
|
|
|
=== Issues
|
|
|
|
1) What should this extension be named?
|
|
|
|
*RESOLVED*: `VK_KHR_get_display_properties2`.
|
|
Other alternatives:
|
|
|
|
* `VK_KHR_display2`
|
|
* One extension, combined with `VK_KHR_surface_capabilites2`.
|
|
|
|
2) Should extensible input structs be added for these new functions:
|
|
|
|
*RESOLVED*:
|
|
|
|
* flink:vkGetPhysicalDeviceDisplayProperties2KHR: No.
|
|
The only current input is a slink:VkPhysicalDevice.
|
|
Other inputs wouldn't make sense.
|
|
* flink:vkGetPhysicalDeviceDisplayPlaneProperties2KHR: No.
|
|
The only current input is a slink:VkPhysicalDevice.
|
|
Other inputs wouldn't make sense.
|
|
* flink:vkGetDisplayModeProperties2KHR: No.
|
|
The only current inputs are a slink:VkPhysicalDevice and a
|
|
slink:VkDisplayModeKHR.
|
|
Other inputs wouldn't make sense.
|
|
|
|
3) Should additional display query functions be extended?
|
|
|
|
*RESOLVED*:
|
|
|
|
* flink:vkGetDisplayPlaneSupportedDisplaysKHR: No.
|
|
Extensions should instead extend
|
|
flink:vkGetDisplayPlaneCapabilitiesKHR().
