In the various versions of acpi_idle_enter, I see the following code. ... cx->usage++; lapic_timer_state_broadcast(pr, cx, 0); cx->time += idle_time; ... But this usage and idle_time and accounted for by the core cpuidle driver, so is this a small bug and the usage and idle_time accounting code should be removed? Also, I see the following: /* Tell the scheduler how much we idled: */ sched_clock_idle_wakeup_event(idle_time_ns); The sched_clock_idle_wakeup_event does nothing with the idle_time_ns parameter it is passed. Perhaps it did at one time. Is this call still necessary?
