* Update release number to 124.
Github Issues:
* Fix Makefile SPECREMARK macro to work when not building in a git tree
(public issue 992).
* Ignore pname:aspectMask for unused attachments in
slink:VkSubpassDescription2KHR valid usage statements (public pull
request 1028).
* Minor markup / spelling fixes (public pull requests 1035, 1045).
Internal Issues:
* Fix markup in Valid Usage statement for slink:VkCreateFramebuffer
(internal issue 1823).
* Add a new <<synchronization-signal-operation-order, _signal operation
order_>> section to the synchronization chapter which describes in
detail the ordering guarantees provided by the API between fence and
semaphore signal operations (internal merge request 3368).
* Move generated `appendix/meta/` files into the Makefile GENERATED
directory (internal merge request 3381).
New Extensions

This extension provides functionality to use a logical device that consists
|
|
of multiple physical devices, as created with the
|
|
`<<VK_KHR_device_group_creation>>` extension.
|
|
A device group can allocate memory across the subdevices, bind memory from
|
|
one subdevice to a resource on another subdevice, record command buffers
|
|
where some work executes on an arbitrary subset of the subdevices, and
|
|
potentially present a swapchain image from one or more subdevices.

The base functionality in this extension is included in core Vulkan 1.1,

=== Version History
|
|
|
|
* Revision 1, 2016-10-19 (Jeff Bolz)
|
|
- Internal revisions
|
|
* Revision 2, 2017-05-19 (Tobias Hector)
|
|
- Removed extended memory bind functions to VK_KHR_bind_memory2, added
|
|
dependency on that extension, and device-group-specific structs for
|
|
those functions.
|
|
* Revision 3, 2017-10-06 (Ian Elliott)
|
|
- Corrected Vulkan 1.1 interactions with the WSI extensions.
|
|
All Vulkan 1.1 WSI interactions are with the VK_KHR_swapchain
|
|
extension.
|
|
* Revision 4, 2017-10-10 (Jeff Bolz)
|
|
- Rename "SFR" bits and structure members to use the phrase "split
|
|
instance bind regions".
