*	Use preempt_enable_no_resched() before calling schedule() anyway.	Bjoern B. Brandenburg	2007-09-23
\|
*	Fix litmus_controlled initialization bug.	Bjoern B. Brandenburg	2007-09-23
\| \| \| \| \|	litmus_controlled was 0 until _after_ first successful wake up. Also adds some more debug info to mode switches.
*	Access per-cpu variable non-preemptively	Bjoern B. Brandenburg	2007-09-23
\| \| \| \| \|	Since SRP only works under partitioning, this is superfluous, but it makes Linux shut up (in debug builds).
*	Fix PSN-EDF scheduling logic.	Bjoern B. Brandenburg	2007-09-23
\| \| \| \|	This fixes a bug with the preemption and non-rt mode logic.
*	Another sanity check.	Bjoern B. Brandenburg	2007-09-23
\|
*	Make sufficient number of PI semaphores and SRP resources available.	Bjoern B. Brandenburg	2007-09-22
\| \| \| \| \|	Also fixes a case where the kernel would have returned to userspace with preemptions disabled.
*	Prevent corruption from multiple Feather-Trace readers.	Bjoern B. Brandenburg	2007-09-22
\| \| \| \|	Introduces Feather-Trace reader semaphore.
*	Some cleanup and an attempt to pin point a race condition.	Bjoern B. Brandenburg	2007-09-22
\|
*	Fix a race between np_mem_kill() and do_exit().	Bjoern B. Brandenburg	2007-09-22
\| \| \| \| \|	Don't try to reference signal related data structures after the tear down of the task has started.
*	Allocate more semaphores for the test runs.	Bjoern B. Brandenburg	2007-09-22
\|
*	reintroduce TS_EXIT_NP_* Feather-Trace events.	Bjoern B. Brandenburg	2007-09-17
\|
*	PSN-EDF now seems to work	Bjoern B. Brandenburg	2007-09-13
\| \| \| \| \|	I cannot reproduce any crashes under QEMU any more, and the code looks like it's ok. I'll test it on the real machine next.
*	add flag based np-sections	Bjoern B. Brandenburg	2007-09-13
\| \| \| \| \| \|	This commit introduces the infrastructure for flag based np sections. It also features an overhauled GSN-EDF scheduler that respects the flags (and has less bugs).
*	Merge with wait_for_job_release().	Bjoern B. Brandenburg	2007-08-23
\|\
\| *	Add wait_for_job system call	Bjoern B. Brandenburg	2007-08-21
\| \| \| \| \| \| \| \|	Allow userspace to wait for a specific job release.
\| *	Add job_no to struct rt_times	Bjoern B. Brandenburg	2007-08-21
\| \| \| \| \| \| \| \| \| \|	Adds the notion of a job sequence number to the LITMUS per-task state. This will allow userspace to refer to specific jobs.
* \|	Change fifo_domain_t to rt_domain_t + bug fixes.	Bjoern B. Brandenburg	2007-08-23
\| \|
* \|	Introduce rt_domain_t.	Bjoern B. Brandenburg	2007-08-23
\|/
*	Fix locking bug in GSN-EDF.RTSS07	Bjoern B. Brandenburg	2007-05-18
\|
*	Fix partition handling of PSN-EDF.	Bjoern B. Brandenburg	2007-05-18
\|
*	Make PI semaphores under PSN-EDF non-preemptable.	Bjoern B. Brandenburg	2007-05-17
\|
*	Let PI semaphores inherit only inside a partition.	Bjoern B. Brandenburg	2007-05-17
\| \| \| \| \|	- Track hp.cpu_task per partition - inherit priority only from local tasks
*	Prepare struct pi_semaphore for per-CPU PI protocol as required by FMLP.	Bjoern B. Brandenburg	2007-05-17
\|
*	Restructure PI semaphores so that they are easier to trace.	Bjoern B. Brandenburg	2007-05-17
\|
*	Add timestamps to semaphore functions	Bjoern B. Brandenburg	2007-05-17
\|
*	Don't disable interrupts in semaphore syscalls.	Bjoern B. Brandenburg	2007-05-17
\| \| \| \| \|	We don't need to protect against interrupts in the semaphore functions since semaphores are never touched from interrupt context.
*	Fix compiler warnings.	Bjoern B. Brandenburg	2007-05-17
\|
*	Make the inclusion of sched_trace_XXX() and TRACE() a configurable option.	Bjoern B. Brandenburg	2007-05-17
\| \| \| \|	This allows us to remove the debugging code from benchmarking kernels.
*	Fix a compiler warning.	Bjoern B. Brandenburg	2007-05-17
\|
*	Insert trigger for enter_np()/exit_np() tracing.	Bjoern B. Brandenburg	2007-05-16
\|
*	Make sched_trace conditional.	Bjoern B. Brandenburg	2007-05-16
\| \| \| \|	TODO: Make it a .config option.
*	Place trigger for scheduling overhead benchmark.	Bjoern B. Brandenburg	2007-05-16
\|
*	Add time stamps for schedule(), the timer interrupt, and the plugin	Bjoern B. Brandenburg	2007-05-16
\| \| \| \|	scheduler_tick() and schedule() callbacks.
*	Change feather-trace device to support enabling and disabling of events.	Bjoern B. Brandenburg	2007-05-16
\|
*	Merged Feather-Trace.	Bjoern B. Brandenburg	2007-05-15
\|
*	Activate ceiling blocking and fix a stupid list corruption bug.	Bjoern B. Brandenburg	2007-05-15
\|
*	Reworked SRP implementation.	Bjoern Brandenburg	2007-05-15
\|
*	PSN-EDF priority inheritance implementation.	Bjoern B. Brandenburg	2007-05-15
\|
*	Move edf_set_hp_task() to litmus_sem.c as it needs to have knowledge of	Bjoern B. Brandenburg	2007-05-15
\| \| \| \|	what is stored in the wait queue's ->private field.
*	PI implementation for sched_gsn_edf.c	Bjoern B. Brandenburg	2007-05-15
\|
*	Fixed several bugs in the semaphore code concerning racing wake ups + misc	Bjoern B. Brandenburg	2007-05-15
\| \| \| \|	fixex.
*	Fix try_to_wake_up() for RT tasks if it races with schedule.	Bjoern B. Brandenburg	2007-05-15
\| \| \| \| \|	We need to set the task state to TASK_RUNNING if it races, otherwise the task might get lost once it gets de-scheduled.
*	First part of the PI semaphore implementation.	Bjoern B. Brandenburg	2007-05-14
\| \| \| \| \| \| \| \| \| \| \|	- move struct pi_semaphore to place where it makes more sense (not included everywhere) - change semantics of scheduler plugin callbacks and add comments - remove old unneeded code - compile fixes Note: The plugins don't actually work yet, since the semantics of the callbacks have changed. That will be fixed in the next patch.
*	Move common code to edf_common.c.	Bjoern B. Brandenburg	2007-05-14
\| \| \| \| \|	Finding the highest-priority task in a pi_semaphore is same in all EDF-based plugins.
*	Fix gsnedf_sleep_next_period() locking.	Bjoern B. Brandenburg	2007-05-14
\|
*	Fix GSN-EDF sleep_next_period	Bjoern B. Brandenburg	2007-05-14
\| \| \| \| \|	The standard EDF implementation does not work for GSN-EDF since it does not perform the task preparation in schedule().
*	Reimplemented LITMUS standard FIFO semaphores + misc fixes	Bjoern B. Brandenburg	2007-05-14
\| \| \| \| \| \| \|	This version is much more straightforward than the last one and actually enforces FIFO order in all cases. Further, it removes the need for the sem_wake_up() calls by providing a custom wake up function for the wait queue.
*	Move specialized PI semaphore code into litmus_sem.c + small fix	Bjoern B. Brandenburg	2007-05-14
\| \| \| \| \| \| \|	- Let's keep all the code belonging to LITMUS in one place, this makes maintenance and porting much easier. - add_wait_queue_exlclusive_locked() sets the exclusive flag anyway
*	Start of LITMUS semaphore, PI, and SRP rewrite.	Bjoern B. Brandenburg	2007-05-14
\| \| \| \| \|	Rearrange the code to get out of the architecture dependent areas of the kernel and make it live in a central file, kernel/litmus_sem.c.
*	Initial implementation of inherit and return priority for PSN-EDF.	Bjoern B. Brandenburg	2007-05-13
