* score: Rename _CORE_RWLock_Obtain()Sebastian Huber2016-04-214-6/+6
| | | | | | | | Rename _CORE_RWLock_Obtain_for_reading() into _CORE_RWLock_Seize_for_reading(). Rename _CORE_RWLock_Obtain_for_writing() into _CORE_RWLock_Seize_for_writing(). Rename _CORE_RWLock_Release() into _CORE_RWLock_Surrender(). This avoids confusion with the ISR lock acquire and release.

| | | | | Remove superfluous _CORE_message_queue_Flush() since we completely re-initialize the structure in _CORE_message_queue_Initialize().

| | | | | | | | | | | Add a lock and use a chain iterator for safe iteration during concurrent user extension addition and removal. Ensure that dynamically added thread delete and fatal extensions are called in reverse order. Update #2555. Update #2692.

* score: Simplify _Objects_Get_no_protection()Sebastian Huber2016-04-123-13/+9
| | | | | | | This functions supports only local objects. Thus, drop the location parameter which was unused by all callers. Remove superfluous includes from Classic Region implementation.

* score: Rework MP thread queue callout supportSebastian Huber2016-04-0623-384/+774
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The thread queue implementation was heavily reworked to support SMP. This broke the multiprocessing support of the thread queues. This is fixed by this patch. A thread proxy is unblocked due to three reasons 1) timeout, 2) request satisfaction, and 3) extraction. In case 1) no MPCI message must be sent. This is ensured via the _Thread_queue_MP_callout_do_nothing() callout set during _Thread_MP_Allocate_proxy(). In case 2) and 3) an MPCI message must be sent. In case we interrupt the blocking operation during _Thread_queue_Enqueue_critical(), then this message must be sent by the blocking thread. For this the new fields Thread_Proxy_control::thread_queue_callout and Thread_Proxy_control::thread_queue_id are used. Delete the individual API MP callout types and use Thread_queue_MP_callout throughout. This type is only defined in multiprocessing configurations. Prefix the multiprocessing parameters with mp_ to ease code review. Multiprocessing specific parameters are optional due to use of a similar macro pattern. There is no overhead for non-multiprocessing configurations.
* score: Simplify _Thread_queue_Do_flush()Sebastian Huber2016-04-061-4/+1
| | | | | Also set the thread wait return code for thread proxies since this causes no harm.
* score: _Thread_queue_Flush() parameter changesSebastian Huber2016-04-0610-150/+154
| | | | | | | | | | | | Change _Thread_queue_Flush() into a macro that invokes _Thread_queue_Do_flush() with the parameter set defined by RTEMS_MULTIPROCESSING. For multiprocessing configurations add the object identifier to avoid direct use of the thread wait information. Use mp_ prefix for multiprocessing related parameters. Rename Thread_queue_Flush_callout to Thread_queue_MP_callout since this type will be re-used later for other operations as well.
* score: Fix _Thread_queue_Extract_locked()Sebastian Huber2016-04-061-4/+8
| | | | | | We must update the wait flags under protection of the current thread lock, otherwise a _Thread_Timeout() running on another processor may interfere.
* score: Delete MP support for RW locksSebastian Huber2016-04-063-36/+13
| | | | MP support was not implemented.
* score: Delete Thread_Wait_information::idSebastian Huber2016-04-0614-13/+100
| | | | | | | | | | | This field was only by the monitor in non-multiprocessing configurations. Add new field Thread_Wait_information::remote_id in multiprocessing configurations and use it for the remote procedure call thread queue. Add _Thread_Wait_get_id() to obtain the object identifier for debug and system information tools. Ensure the object layout via static asserts. Add test cases to sptests/spthreadq01.
* score: Add and use _RBTree_Insert_inline()Sebastian Huber2016-04-011-0/+40
