* score: Rename to _Scheduler_ControlSebastian Huber2017-09-271-2/+2
| | | | | | | Rename struct Scheduler_Control to _Scheduler_Control to allow its use in standard header files, e.g. <pthread.h>. Update #3112.
* score: Rework thread priority managementSebastian Huber2016-09-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Add priority nodes which contribute to the overall thread priority. The actual priority of a thread is now an aggregation of priority nodes. The thread priority aggregation for the home scheduler instance of a thread consists of at least one priority node, which is normally the real priority of the thread. The locking protocols (e.g. priority ceiling and priority inheritance), rate-monotonic period objects and the POSIX sporadic server add, change and remove priority nodes. A thread changes its priority now immediately, e.g. priority changes are not deferred until the thread releases its last resource. Replace the _Thread_Change_priority() function with * _Thread_Priority_perform_actions(), * _Thread_Priority_add(), * _Thread_Priority_remove(), * _Thread_Priority_change(), and * _Thread_Priority_update(). Update #2412. Update #2556.
* score: Introduce map priority scheduler operationSebastian Huber2016-06-221-0/+9
| | | | | | | | | | | Introduce map/unmap priority scheduler operations to map thread priority values from/to the user domain to/from the scheduler domain. Use the map priority operation to validate the thread priority. The EDF schedulers use this new operation to distinguish between normal priorities and priorities obtain through a job release. Update #2173. Update #2556.
* score: Use owner of thread queue for CORE mutexSebastian Huber2016-05-301-10/+6
|
* score: Rework CORE inherit priority mutexSebastian Huber2016-05-301-49/+0
| | | | | Provide dedicated seize and surrender methods for inherit priority mutexes. This eliminates CORE_mutex_Attributes.
* score: Rework CORE priority ceiling mutexSebastian Huber2016-05-301-24/+0
| | | | | Rework seize and surrender methods to use CORE_ceiling_mutex_Control. This eliminates CORE_mutex_Disciplines.
* score: Add CORE mutex variantsSebastian Huber2016-05-301-13/+30
| | | | | | | | Add CORE_recursive_mutex_Control and CORE_ceiling_mutex_Control to avoid the run-time evaluation of attributes to figure out how a particular mutex methods should behave. Start with the no protocol variants. This eliminates the CORE_MUTEX_DISCIPLINES_FIFO and CORE_MUTEX_DISCIPLINES_PRIORITY disciplines.
* score: Simplify CORE mutexSebastian Huber2016-05-301-7/+0
| | | | | Remove superfluous support for simple binary semaphores. With this we can get rid of the CORE_MUTEX_NESTING_BLOCKS variant.
* score: Delete __RTEMS_STRICT_ORDER_MUTEX__Sebastian Huber2016-05-021-25/+0
| | | | | | Remove support for strict order mutexes. Close #2124.
* score: Remove Thread_queue_Queue::operations fieldSebastian Huber2016-03-291-0/+6
| | | | | | | | | Remove the Thread_queue_Queue::operations field to reduce the size of this structure. Add a thread queue operations parameter to the _Thread_queue_First(), _Thread_queue_First_locked(), _Thread_queue_Enqueue(), _Thread_queue_Dequeue() and _Thread_queue_Flush() functions. This is a preparation patch to reduce the size of several synchronization objects.
* score: Delete CORE_mutex_Control::lockSebastian Huber2014-03-311-3/+0
| | | | | | | | The holder field is enough to determine if a mutex is locked or not. This leads also to better error status codes in case a rtems_semaphore_release() is done for a mutex without having the ownership.
* score: Delete CORE_mutex_Control::holder_idSebastian Huber2014-03-311-2/+0
| | | | We can use the holder pointer to get the identifier if necessary.

Some of these services incorrectly took a timeout as a relative time. Others would compute a 0 delta to timeout if the absolute time and the current time were equal and thus incorrectly block the caller forever. The root of the confusion is that POSIX specifies that if the timeout is incorrect (e.g. in the past, is now, or is numerically invalid), that it does not matter if the call would succeed without blocking. This is in contrast to RTEMS programming style where all errors are checked before any critical sections are entered. This fix implemented a more uniform way of handling POSIX absolute time timeouts. + pthread_cond_timedwait - could block forever + mq_timedreceive - used relative not absolute time + mq_timedsend - used relative not absolute time + pthread_mutex_timedlock - used relative not absolute time + pthread_rwlock_timedrdlock- used relative not absolute time + pthread_rwlock_timedwrlock- used relative not absolute time + sem_timedwait - could block forever
