* Fix semaphore post overflow statusSebastian Huber2016-05-262-2/+3
| | | | Close #2720.

| | | | Close #2719.
* score: Move thread queue MP callout to contextSebastian Huber2016-05-2533-965/+678
| | | | | | | | Drop the multiprocessing (MP) dependent callout parameter from the thread queue extract, dequeue, flush and unblock methods. Merge this parameter with the lock context into new structure Thread_queue_Context. This helps to gets rid of the conditionally compiled method call helpers.
* score: Get rid of mp_id parameterSebastian Huber2016-05-2523-133/+22
| | | | | Get rid of the mp_id parameter used for some thread queue methods. Use THREAD_QUEUE_QUEUE_TO_OBJECT() instead.
* score: Move thread queue object supportSebastian Huber2016-05-253-26/+29

* mpci: Fix thread queue flush methodSebastian Huber2016-05-256-97/+56
| | | | | | | We must call the MP callout for proxies if we unblock them after a thread queue extraction. This was missing in _Thread_queue_Flush_critical(). Move thread remove timer and unblock code to new function _Thread_Remove_timer_and_unblock().
* score/i386: Fix printk format warnings.Chris Johns2016-05-251-5/+7

* cpukit, testsuite: Add rtems_printf and rtems_printer support.Chris Johns2016-05-251-17/+13
| | | | | | | | | | | | | | | | | | | This change adds rtems_printf and related functions and wraps the RTEMS print plugin support into a user API. All references to the plugin are removed and replaced with the rtems_printer interface. Printk and related functions are made to return a valid number of characters formatted and output. The function attribute to check printf functions has been added to rtems_printf and printk. No changes to remove warrnings are part of this patch set. The testsuite has been moved over to the rtems_printer. The testsuite has a mix of rtems_printer access and direct print control via the tmacros.h header file. The support for begink/endk has been removed as it served no purpose and only confused the code base. The testsuite has not been refactored to use rtems_printf. This is future work.
* score: Fix blocking _CORE_message_queue_Submit()Sebastian Huber2016-05-242-4/+3
| | | | Close #2718.
* score: _CORE_message_queue_Seize()Sebastian Huber2016-05-242-4/+0
| | | | Delete unused parameter.
* score: _CORE_semaphore_Seize()Sebastian Huber2016-05-202-3/+0
| | | | Delete unused parameter.
* Replace *_Get_interrupt_disable() with *_Get()Sebastian Huber2016-05-207-7/+7
| | | | | Uniformly use *_Get() to get an object by identifier with a lock context.
* score: Rename _Objects_Get_local()Sebastian Huber2016-05-206-6/+6
| | | | | | Rename _Objects_Get_local() into _Objects_Get(). Confusions with the previous _Objects_Get() function are avoided since the Objects_Locations parameter is gone.
* score: Delete unused _Objects_Get_isr_disable()Sebastian Huber2016-05-203-98/+1
| | | | Delete now unused Objects_Locations.
* mpci: Simplify _Objects_MP_Is_remote()Sebastian Huber2016-05-204-22/+20

* score: Use _RBTree_Insert_inline()Sebastian Huber2016-05-203-42/+22
| | | | | | Use _RBTree_Insert_inline() for priority thread queues. Update #2556.
* score: Add per scheduler instance maximum prioritySebastian Huber2016-05-206-8/+22
| | | | | | | | | | | The priority values are only valid within a scheduler instance. Thus, the maximum priority value must be defined per scheduler instance. The first scheduler instance defines PRIORITY_MAXIMUM. This implies that RTEMS_MAXIMUM_PRIORITY and POSIX_SCHEDULER_MAXIMUM_PRIORITY are only valid for threads of the first scheduler instance. Further API/implementation changes are necessary to fix this. Update #2556.
