* 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).

|
This extension adds the device coherent and device uncached memory types.
|
|
Any device accesses to device coherent memory are automatically made visible
|
|
to any other device access.
|
|
Device uncached memory indicates to applications that caches are disabled
|
|
for a particular memory type, which guarantees device coherence.
|
|
|
|
Device coherent and uncached memory are expected to have lower performance
|
|
for general access than non-device coherent memory, but can be useful in
|
|
certain scenarios; particularly so for debugging.
