Since commit 2159197d6677 ("sched/core: Enable increased load resolution
on 64-bit kernels") we now have two different fixed point units for
load.
load_above_capacity has to have 10 bit fixed point unit like PELT
whereas NICE_0_LOAD has 20 bit fixed point unit on 64-bit kernels.
Fix this by scaling down NICE_0_LOAD when multiplying
load_above_capacity with it.Signed-off-by: Dietmar Eggemann <[email protected]> Acked-by: Morten Rasmussen <[email protected]> --- kernel/sched/fair.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/sched/fair.c b/kernel/sched/fair.c index 4088eedea763..fe4093807852 100644 --- a/kernel/sched/fair.c +++ b/kernel/sched/fair.c @@ -7147,7 +7147,7 @@ static inline void calculate_imbalance(struct lb_env *env, struct sd_lb_stats *s load_above_capacity = busiest->sum_nr_running * SCHED_CAPACITY_SCALE; if (load_above_capacity > busiest->group_capacity) { load_above_capacity -= busiest->group_capacity; - load_above_capacity *= NICE_0_LOAD; + load_above_capacity *= scale_load_down(NICE_0_LOAD); load_above_capacity /= busiest->group_capacity; } else load_above_capacity = ~0UL; -- 1.9.1
