* Update release number to 108.
Internal Issues:
* Clarify that only external resources can be bound to external memory in
valid usage statements for flink:vkBindBufferMemory,
flink:vkBindImageMemory, slink:VkSparseMemoryBind, and
slink:VkSparseImageMemoryBind (internal issue 1496).
* Move all `vk.xml`requirements for
flink:vkGetDeviceGroupSurfacePresentModes2EXT into
`<<VK_EXT_full_screen_exclusive>>` (internal issue 1622).
* Add some missing valid usage statements for
flink:vkCmdEndQueryIndexedEXT (internal issue 1638).
* Specify rules for defining "`New Flags and Bitmask Types`" in that
section of the style guide (internal issue 1649).
* Add a comment to the `vk.xml` extension block for
`VK_ANDROID_native_buffer` explaining why the extension is tagged
`"disabled"` (internal issue 1657).
* Fix typos in the description of slink:VkImageViewCreateInfo (internal
issue 1661).
* Modify valid usage statements for slink:VkImageViewCreateInfo to fix the
description about the restriction for pname:baseArrayLayer and
pname:layerCount from pname:extent.depth to the depth of mipmap level
while creating a 2D array image view on a 3D image.
* Forbid structures that contain opaque types (images or samplers) in the
SPIR-V <<spirvenv-module-validation, Validation Rules within a Module>>
section.
* Minor editorial changes for the `VK_EXT_swapchain_colorspace` extension
in the description of slink:VkColorSpace KHR and `vk.xml`, including:
** Consistently specify which function (OETF or Inverse-EOTF) is being
defined;
** Remove the Display P3 EOTF, since no other EOTFs are defined;
** Include luminance range for the HLG OETF;
** Remove a duplicated paragraph; and,
** Rename ename:VK_COLOR_SPACE_DISPLAY_P3_LINEAR_EXT, leaving the old
ename:VK_COLOR_SPACE_DCI_P3_LINEAR_EXT token as an alias.
New Extensions:
* `<<VK_NV_framebuffer_mixed_samples_coverage_reduction_mode>>`
* `<<VK_KHR_uniform_buffer_standard_layout>>`

=== Short Description
|
|
|
|
Enables tighter array and struct packing to be used with uniform buffers.
|
|
|
|
=== Description
|
|
|
|
This extension modifies the alignment rules for uniform buffers, allowing
|
|
for tighter packing of arrays and structures.
|
|
This allows, for example, the std430 layout, as defined in
|
|
https://www.khronos.org/registry/OpenGL/specs/gl/GLSLangSpec.4.60.pdf[GLSL]
|
|
to be supported in uniform buffers.
|
|
|
|
=== New Enum Constants
|
|
|
|
* Extending elink:VkStructureType:
|
|
** ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_UNIFORM_BUFFER_STANDARD_LAYOUT_FEATURES_KHR
|
|
|
|
=== New Structures
|
|
|
|
* slink:VkPhysicalDeviceUniformBufferStandardLayoutFeaturesKHR
|
|
|
|
=== Issues
|
|
|
|
None.
