Proto:static void enqueue_dl_entity(struct sched_dl_entity *dl_se, struct sched_dl_entity *pi_se, int flags)

Type:void

Parameter:

Type	Parameter	Name
struct sched_dl_entity *	dl_se
struct sched_dl_entity *	pi_se
int	flags

If flags & ENQUEUE_WAKEUP Then

1454

task_contending(dl_se, flags)

1455

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.

1456

Else if flags & ENQUEUE_REPLENISH Then

1457

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

1458

Else if flags & ENQUEUE_RESTORE && dl_time_before( Absolute deadline for this instance , rq_clock(rq_of_dl_rq(dl_rq_of_se(dl_se)))) Then

1461

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
