LITMUS^RT core: keep track of time of last suspension

2016-06-23T10:32:22+00:00

This information is needed to insert ST_COMPLETION records for
sporadic tasks.

LITMUS^RT core: be more careful when pull-migrating tasks

2016-03-08T15:12:52+00:00

Close more race windows and give plugins a chance to validate
tasks after they have been migrated.

LITMUS^RT core: add next_became_invalid() callback

2016-03-08T15:12:50+00:00

LITMUS^RT core: add should_wait_for_stack() callback

2016-03-08T15:12:49+00:00

Allow plugins to give up when waiting for a stack to become available.

LITMUS^RT: improve integration with fork()

2016-03-08T15:12:45+00:00

LITMUS^RT scheduling class: mark enqueued task as present

Protect LITMUS^RT tasks from re-nicing

2015-08-09T11:20:33+00:00

Assigning a nice value to LITMUS^RT tasks is meaningless. Bail out
early.

Don't call set_tsk_need_resched() on remote LITMUS^RT task

2015-08-09T11:20:32+00:00

This patch fixes a BUG_ON() in litmus/preempt.c.

Hook into SCHED_DEADLINE to protect LITMUS^RT tasks

2015-08-09T11:20:32+00:00

SCHED_DEADLINE should not preempt LITMUS^RT tasks, as the LITMUS^RT
scheduling class is positioned above the SCHED_DEADLINE policy.

Hook into rt scheduling class to protect LITMUS^RT tasks

2015-08-09T11:20:31+00:00

The rt scheduling class thinks it's the highest-priority scheduling
class around, next to SCHED_DEADLINE. It is not in LITMUS^RT. Don't go
preempting remote cores that run SCHED_LITMUS tasks.
