/* Submitted fences are added to pending_syncs first. How submitted fences

|
* VKR_RENDERER_ASYNC_FENCE_CB.
|
|
*
|
|
* When VKR_RENDERER_THREAD_SYNC is not set, the main thread calls
|
|
* vkGetFenceStatus and retires signaled fences in pending_syncs in order.
|
|
*
|
|
* When VKR_RENDERER_THREAD_SYNC is set but VKR_RENDERER_ASYNC_FENCE_CB is
|
|
* not set, the sync thread calls vkWaitForFences and moves signaled fences
|
|
* from pending_syncs to signaled_syncs in order. The main thread simply
|
|
* retires all fences in signaled_syncs.
|

*
|
|
* When VKR_RENDERER_THREAD_SYNC and VKR_RENDERER_ASYNC_FENCE_CB are both
|
|
* set, the sync thread calls vkWaitForFences and retires signaled fences
|
|
* in pending_syncs in order.
