| | | |||
| * | 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 |
| | | |||

| | | |||

| | | |||
| * | 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. | ||
| * | Remove old, unneeded ASM cruft. | Bjoern B. Brandenburg | 2007-05-14 |
| | | |||
| * | Initial implementation of inherit and return priority for PSN-EDF. | Bjoern B. Brandenburg | 2007-05-13 |
| | | |||
| * | Streamline PI implementation a little. | Bjoern B. Brandenburg | 2007-05-13 |
| | | |||
| * | Kick out commented ASM code. | Bjoern B. Brandenburg | 2007-05-13 |
| | | |||
| * | Added psnedf_handle_priority_change() implementation | Bjoern B. Brandenburg | 2007-05-13 |
| | | |||
| * | NP section backport and debug fixes | Bjoern B. Brandenburg | 2007-05-13 |
| | | | | | | | - port NP section logic from PSN-EDF to GSN-EDF - remove old debugging stuff from GSN-EDF - add some tracing info | ||
| * | Add macros for convenient task tracing. | Bjoern B. Brandenburg | 2007-05-13 |
| | | |||
| * | Add a whole bunch of TRACEs to facilitate debugging. | Bjoern B. Brandenburg | 2007-05-13 |
| | | |||
| * | TRACE RT task arrivals and departures. | Bjoern B. Brandenburg | 2007-05-13 |
| | | |||
| * | Improve debugging output and support | Bjoern B. Brandenburg | 2007-05-13 |
| | | | | | | | - TRACE jobs being queued - TRACE enter_np/exit_np - fix double assignment of F in sysrq handlers | ||
| * | Pay attention to (preempt_count() & PREEMPT_ACTIVE) hack. | Bjoern B. Brandenburg | 2007-05-13 |
| | | | | | | | | | | | This change should fix the long standing problem that certain IO intensive work loads would "crash" the kernel. What really happened was that real-time tasks caught an interrupt right before they would have called schedule as a part of a suspension anyway. As they were already in a different state then TASK_RUNNING, they were not requeued and got lost. If they were holding important locks (such as a TTY lock or the BKL), then "bad things" happened... | ||
| * | Use volatile access and relax_cpu() in queue lock. | Bjoern B. Brandenburg | 2007-05-13 |
| | | |||
| * | PSN-EDF fixes. | Bjoern B. Brandenburg | 2007-05-10 |
| | | | | | | | - fix recursive lock acquisition of cpu state lock, found by deplock - properly guard cpu state during mode change - cosmetic fix in initialization | ||
| * | Pull in John's SRP fixes. | Bjoern B. Brandenburg | 2007-05-10 |
| |\ | | | | | | | Merge with git+ssh://cvs/cvs/proj/litmus/repo/litmus | ||
| | * | Modified SRP semaphores so that waiting for prio to exceed SPC works | John M. Calandrino | 2007-05-10 |
| | | | | | | | | | correctly, mostly by adding waitqueues and rewriting wait_until_exceed_spc. | ||
| * | | Add PSN-EDF. | Bjoern B. Brandenburg | 2007-05-10 |
| | | | |||
| * | | Minor fixes. | Bjoern B. Brandenburg | 2007-05-10 |
| | | | |||
| * | | Break out __release_pending() from try_release_pending() | Bjoern B. Brandenburg | 2007-05-10 |
| | | | |||
| * | | Some random code cleanup. | Bjoern B. Brandenburg | 2007-05-10 |
| | | | | | | | | | | | | | - IRQs are disabled in _schedule - use TRACE - coding style | ||
