Name:dl_rq_of_se
Proto:static inline struct dl_rq *dl_rq_of_se(struct sched_dl_entity *dl_se)
Type:struct dl_rq
Parameter:
Type | Parameter | Name |
---|---|---|
struct sched_dl_entity * | dl_se |
35 | p = dl_task_of(dl_se) |
38 | Return dl |
Name | Describe |
---|---|
task_non_contending | The utilization of a task cannot be immediately removed from* the rq active utilization (running_bw) when the task blocks |
task_contending | |
setup_new_dl_entity | We are being explicitly informed that a new instance is starting,* and this means that:* - the absolute deadline of the entity has to be placed at* current time + relative deadline;* - the runtime of the entity has to be set to the maximum value |
replenish_dl_entity | Pure Earliest Deadline First (EDF) scheduling does not deal with the* possibility of a entity lasting more than what it declared, and thus* exhausting its runtime |
update_dl_entity | When a deadline entity is placed in the runqueue, its runtime and deadline* might need to be updated. This is done by a CBS wake up rule. There are two* different rules: 1) the original CBS; and 2) the Revisited CBS. |
dl_check_constrained_dl | During the activation, CBS checks if it can reuse the current task's* runtime and period |
