Keith Ah, OK, this one more or less slipped through. I might need to revert that. In a situation where there are many processes waiting on the hardware lock, and one process grabs it, the lock will lose the CONTENDED flag, until one of the sleeping processes is woken up by a clock tick and sends the CONTENDED flag again. The process taking the lock will not call the kernel to wake up sleeping processes, and can retake the lock again without calling the kernel. This is not an ideal situation, and the change makes sure that the process taking the lock calls the kernel again to wake up any sleeping processes even if there are none available. This seems improve scheduling at the cost of some extra CPU when there are more than one DRI client. /Thomas ------------------------------------------------------------------------- Using Tomcat but need to do more?
