* 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
* `<<VK_KHR_shader_clock>>`
* `<<VK_KHR_timeline_semaphore>>`

This extension allows the application to query a 64-bit buffer device
|
|
address value for a buffer, which can be used to access the buffer memory
|
|
via the code:PhysicalStorageBufferEXT storage class in the
|
|
https://github.com/KhronosGroup/GLSL/blob/master/extensions/ext/GLSL_EXT_buffer_reference.txt[`GL_EXT_buffer_reference`]
|
|
GLSL extension and
|
|
{spirv}/EXT/SPV_EXT_physical_storage_buffer.html[`SPV_EXT_physical_storage_buffer`]
|
|
SPIR-V extension.
|
|
|
|
It also allows buffer device addresses to be provided by a trace replay
|
|
tool, so that it matches the address used when the trace was captured.

=== Issues
|
|
|
|
1) Where is VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_ADDRESS_FEATURES_EXT
|
|
and VkPhysicalDeviceBufferAddressFeaturesEXT?
|
|
|
|
*RESOLVED*: They were renamed as
|
|
ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_DEVICE_ADDRESS_FEATURES_EXT
|
|
and slink:VkPhysicalDeviceBufferDeviceAddressFeaturesEXT accordingly for
|
|
consistency.
|
|
Even though, the old names can still be found in the generated header files
|
|
for compatibility.
