However OPAL events are not # particularly performance or latency critical, so they can all be # invoked by kopald. # # This patch removes the irq_work queueing, and instead wakes up # kopald when there is an event to be processed. kopald processes # interrupts individually, enabling irqs and calling cond_resched # between each one to minimise latencies. # # Event handlers themselves should still use threaded handlers, # workqueues, etc. as necessary to avoid high interrupts-off latencies # within any single interrupt. # # Signed-off-by: Nicholas Piggin # Signed-off-by: Michael Ellerman
