CC: Arjan and linux-acpi mailing list. It seems that the selection of C-state will become very sensitive to IO wait after the multi factor is changed from 10 to 1000. Maybe only one IO/wait will bring that the system can't enter the deep C-state. > > Signed-off-by: Eric Anholt <[email protected]> > --- > drivers/cpuidle/governors/menu.c | 2 +- > 1 files changed, 1 insertions(+), 1 deletions(-) > > diff --git a/drivers/cpuidle/governors/menu.c > b/drivers/cpuidle/governors/menu.c > index f508690..9bb5654 100644 > --- a/drivers/cpuidle/governors/menu.c > +++ b/drivers/cpuidle/governors/menu.c > @@ -175,7 +175,7 @@ static inline int performance_multiplier(void) > mult += 2 * get_loadavg(); > > /* for IO wait tasks (per cpu!) we add 5x each */ > - mult += 10 * nr_iowait_cpu(smp_processor_id()); > + mult += 1000 * nr_iowait_cpu(smp_processor_id()); > > return mult; > } _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
