Borderlands The Pre Sequel [BLES02997] fifo desync

[dyno0]

Issue is present with both master 8818 and latest PR from which I attached the log.
After PR #6678 there was a slight improvement but errors started to be inconsistent, where sometimes it would fifo desync and timeout the semaphore, and sometimes catch an exception and stop the system (exception happened a few times but couldn't get the log beacuse emulator didn't close properly after that).

Update: After numerous tests I noticed that the desync happens always at the same semaphore address which is 0x60300E50

RSX: nv406e::semaphore_acquire has timed out. semaphore_address=0x60300E50

Tested with #7136 , after all the significant rsx merges. No desyncs in ~2 hour session, and significantly less fifo and invalid dma value warnings.

Retest with rsx wake-up delay.

Works good with 0.4 - 0.5ms delay with no visible performance loss. Should I close the issue or is the delay modifier considered hacky?

[elad335]

Close.
