scottl 2004/01/29 23:04:39 PST FreeBSD src repository Modified files: sys/dev/aac aac.c aac_pci.c aacvar.h Log: Take the plunge and make this driver be INTR_FAST. This re-arranges the interrupt handler so that no locks are needed, and schedules the command completion routine with a taskqueue_fast. This also corrects the locking in the command thread and removes the need for operation flags. Simple load tests show that this is now considerably faster than FreeBSD 4.x in the SMP case when multiple i/o tasks are running.
