* Bump API patch number and header version number to 54 for this update.
Github Issues:
Internal Issues:
* Fix tessellation domain to have an upper-left origin in the
<<img-tessellation-topology-ul, tessellation toplogy image>> and related
language. CTS and all implementations were already doing this, it was
just a documentation bug that it was flipped to lower-left (internal
issue 603).
* Add a section to the style guide describing how VUID tags are changed
and removed when the corresponding Valid Usage statements are modified
(internal issue 829).
* Add explicit Valid Usage statement to
slink:VkPipelineDynamicStateCreateInfo to require that members of
pname:pDynamicStates must be unique (internal issue 851).

An application using external memory may wish to synchronize access to that
|
|
memory using fences.
|
|
This extension enables an application to export fence payload to and import
|
|
fence payload from Windows handles.

=== Issues
|
|
|
|
This extension borrows concepts, semantics, and language from
|
|
<<VK_KHR_external_semaphore_win32,VK_KHR_external_semaphore_win32>>.
|
|
That extension's issues apply equally to this extension.
|
|
|
|
1) Should D3D12 fence handle types be supported, like they are for
|
|
semaphores?
|
|
|
|
*RESOLVED*: No.
|
|
Doing so would require extending the fence signal and wait operations to
|
|
provide values to signal / wait for, like sname:VkD3D12FenceSubmitInfoKHR
|
|
does.
|
|
A D3D12 fence can be signaled by importing it into a elink:VkSemaphore
|
|
instead of a elink:VkFence, and applications can check status or wait on the
|
|
D3D12 fence using non-Vulkan APIs.
|
|
The convenience of being able to do these operations on sname:VkFence
|
|
objects doesn't justify the extra API complexity.
