Type:struct cfs_rq
Parameter:
Type | Parameter | Name |
---|---|---|
struct sched_entity * | se |
455 | Return cfs |
Name | Describe |
---|---|
sched_slice | We calculate the wall-time slice from the period by taking a part* proportional to the weight.* s = p*P[w/rw] |
update_curr_fair | |
reweight_task | |
__clear_buddies_last | |
__clear_buddies_next | |
__clear_buddies_skip | |
enqueue_task_fair | The enqueue_task method is called before nr_running is* increased. Here we update the fair scheduling stats and* then put the task into the rbtree: |
dequeue_task_fair | The dequeue_task method is called before nr_running is* decreased. We remove the task from the rbtree and* update the fair scheduling stats: |
set_last_buddy | |
set_next_buddy | |
set_skip_buddy | |
check_preempt_wakeup | Preempt the current task with a newly woken task if needed: |
put_prev_task_fair | Account for a descheduled task: |
yield_to_task_fair | |
task_tick_fair | scheduler tick hitting a task of our scheduling class |
detach_entity_cfs_rq | |
attach_entity_cfs_rq | |
detach_task_cfs_rq | |
attach_task_cfs_rq | |
set_next_task_fair | Account for a task changing its policy or group.* This routine is mostly called to set cfs_rq->curr field when a task* migrates between groups/classes. |
