A semaphore type called "progress fence" is derived from the GL semaphore. The progress fence semaphore is created by CreateProgressFenceNVX() returning the name of a newly created semaphore object. Like other semaphores, these are signaled by the GL server. Each signal operation is queued in the GPU command stream with an associated fence value that is written to the semaphore at the completion of a signal operation. A GL server wait can be added to the command stream using WaitSemaphoreui64NVX. This blocks the GPU until the progress fence semaphore reaches or exceeds the specified fence value. A GL client wait can be initiated using ClientWaitSemaphoreui64NVX. This blocks the CPU until the specified fence value is reached.
