jhb 2000/11/01 10:40:02 PST Modified files: sys/alpha/alpha interrupt.c sys/alpha/include intr.h Log: - Modify alpha_setup_intr() to take interrupt handler flags as an additional argument. These flags include INTR_FAST, INTR_MPSAFE, etc. - Properly handle INTR_EXCL when it is passed in to allow an interrupt handler to claim exclusive ownership of an interrupt thread. - Add support for psuedo-fast interrupts on the alpha. For fast interrupts, we don't allocate an interrupt thread; instead, during dispatching of an interrupt, we run the handler directly instead of scheduling the thread to run. Note that the handler is currently run without Giant and must be MP safe. The only fast handler currently is for the sio driver.
