* doxygen: Rename Score* groups in RTEMSScore*Sebastian Huber2019-04-041-1/+1
| | | | Update #3706
* score: Add thread pin/unpin supportSebastian Huber2018-09-101-23/+73
| | | | | | | | | Add support to temporarily pin a thread to its current processor. This may be used to access per-processor data structures in critical sections with enabled thread dispatching, e.g. a pinned thread is allowed to block. Update #3508.
* score: Fix EDF SMP schedulerSebastian Huber2018-09-031-1/+24
| | | | | Fix a special case: block a one-to-one scheduled thread while having a non-empty affine ready queue on the same processor.
* score: Generalize SMP scheduler block supportSebastian Huber2018-09-031-1/+2
| | | | | | Add extract from scheduled function to the _Scheduler_SMP_Block() operation. This allows a scheduler implementation to do extra work in case a scheduled node is blocked.
* score: Fix _Scheduler_EDF_SMP_Set_affinity()Sebastian Huber2018-07-181-7/+5
| | | | | | Commit 8744498752ad4f0eaf9fb5640c6a0e0f2dc92fda broke the _Scheduler_EDF_SMP_Set_affinity() implementation. We must test the overall affinity against the online processors.
* score: Optimize scheduler priority updatesSebastian Huber2017-11-201-139/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thread priority changes may append or prepend the thread to its priority group on the scheduler ready queue. Previously, a separate priority value and a prepend-it flag in the scheduler node were used to propagate a priority change to the scheduler. Now, use an append-it bit in the priority control and reduce the plain priority value to 63 bits. This change leads to a significant code size reduction (about 25%) of the SMP schedulers. The negligible increase of the standard priority scheduler is due to some additional shift operations (SCHEDULER_PRIORITY_MAP() and SCHEDULER_PRIORITY_UNMAP()).

* score: Adjust _Scheduler_EDF_SMP_Insert_ready()Sebastian Huber2017-11-171-6/+4
| | | | | Use only one parameter to compute the next generation. Use index 0 for LIFO ordering, and index 1 for FIFO ordering.
* score: Fix _Scheduler_Set_affinity()Sebastian Huber2017-10-281-5/+4
|
* score: Simplify SMP get lowest scheduledSebastian Huber2017-10-281-3/+2
| | | | | | There is no need to pass in the order relation since the scheduled threads reside on an already ordered chain. The caller will decide what to do with the lowest scheduled thread.
