Hi!
The macro DRM_WAIT_ON changed behaviour.
In earlier DRMs it checked every HZ for "condition" in case it was slightly missed.
This doesn't happen anymore, which means some applications freezes for about 3 secs, when they
just missed an interrupt.
This in itself is a little bit strange since, if the following occurs:
* Check condition * if false, go to sleep
and DRM_WAKEUP is called by the interrupt handler in between those two, the sleep should never occur, which now it seems to do anyway.
Could we pls have the old behaviour back?
