* posix: _POSIX_Message_queue_Create_support()Sebastian Huber2016-05-021-14/+0
| | | | | Make _POSIX_Message_queue_Create_support() static since it is only used by mq_open().

* posix: Use _Objects_Get_local() for semaphoresSebastian Huber2016-04-221-7/+4
| | | | | This simplifies the code since the object location is no longer used. Remove superfluous header includes.
* score: Avoid Giant lock for CORE mtx/semSebastian Huber2016-04-221-23/+3
| | | | | | | Avoid Giant lock for CORE mutex and semaphore flush and delete operations. Update #2555.
* score: Optimize _Objects_Get_local()Sebastian Huber2016-04-212-2/+2
| | | | | Make the id the first parameter since usual callers get the object identifier as the first parameter themself.
* score: Optimize _Objects_Get_no_protection()Sebastian Huber2016-04-211-1/+1
| | | | | Make the id the first parameter since usual callers get the object identifier as the first parameter themself.
* posix: Avoid Giant lock for mutexesSebastian Huber2016-04-211-14/+0
| | | | | | | Delete _POSIX_Mutex_Get(). Use _POSIX_Mutex_Get_interrupt_disable() instead. Update #2555.
* posix: Simplify _POSIX_Mutex_Get_interrupt_disableSebastian Huber2016-04-211-7/+7
| | | | Remove superfluous location parameter.
* score: Fix _CORE_semaphore_Flush()Sebastian Huber2016-04-211-1/+0
| | | | | | | Use proper CORE_semaphore_Status for _CORE_semaphore_Flush() and _CORE_semaphore_Destroy() operations. Close #2696.
* posix: Rename killinfo()Sebastian Huber2016-04-121-1/+1
| | | | | | Apparently killinfo() is not defined by POSIX, glibc or FreeBSD. Rename killinfo() to _POSIX_signals_Send() to cleary mark it as an internal function.
* score: Simplify _Objects_Get_no_protection()Sebastian Huber2016-04-121-7/+2
| | | | | | | This functions supports only local objects. Thus, drop the location parameter which was unused by all callers. Remove superfluous includes from Classic Region implementation.

| | | | Update #2555.

* score: Rework MP thread queue callout supportSebastian Huber2016-04-061-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Delete Thread_Wait_information::idSebastian Huber2016-04-064-4/+4
| | | | | | | | | | | 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 Huber2016-04-011-22/+4

* score: Remove Thread_queue_Queue::operations fieldSebastian Huber2016-03-293-0/+16
| | | | | | | | | 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: Avoid Giant lock for CORE spinlockSebastian Huber2016-03-181-17/+10
| | | | | | Use an ISR lock to protect the spinlock state. Remove empty attributes. Update #2555.
* score: Add _Objects_Get_by_name()Sebastian Huber2016-03-183-39/+33
| | | | | | | | | | Replace _Objects_Name_to_id_string() with _Objects_Get_by_name() since all users of this function are interested in the object itself and not the identifier. Use the object allocator lock to protect the search. Update #2555.
* posix: Use per-thread lookup tree for POSIX KeysSebastian Huber2016-03-182-88/+94
| | | | | | Yields higher performance on SMP systems. Close #2625.
* score: Add and use _Objects_Get_local()Sebastian Huber2016-03-141-3/+1
| | | | | | This simplifies the handling with local-only objects. Update #2555.

* posix: Store unblocked signalsSebastian Huber2015-12-151-2/+2
| | | | | Store the unblock signals to exploit the zero-initialization of the thread control block.
* posix: Require struct _pthread_cleanup_contextSebastian Huber2015-11-242-20/+0
| | | | | This structure is available in Newlib since 2013-11-29 (Git commit a534dfd26e765047621acd0eda656ded886e7108).
* various .h files: Add missing C++ extern wrappersMartin Galvan2015-09-031-1/+4
| | | | Updates #2405.
* score: Rename _POSIX_Absolute_timeout_to_ticks()Sebastian Huber2015-07-281-72/+0
| | | | | | Rename _POSIX_Absolute_timeout_to_ticks() to _TOD_Absolute_timeout_to_ticks() and move it to the score directory. Delete empty <rtems/posix/time.h>.
* score: Introduce Thread_queue_HeadsSebastian Huber2015-07-231-3/+3
| | | | | | | | | | | | | Move the storage for the thread queue heads to the threads. Each thread provides a set of thread queue heads allocated from a dedicated memory pool. In case a thread blocks on a queue, then it lends its heads to the queue. In case the thread unblocks, then it takes a free set of threads from the queue. Since a thread can block on at most one queue this works. This mechanism is used in FreeBSD. The motivation for this change is to reduce the memory demands of the synchronization objects. On a 32-bit uni-processor configuration the Thread_queue_Control size is now 8 bytes, compared to 64 bytes in RTEMS 4.10 (other changes reduced the size as well).
* score: Freechain handler API changesSebastian Huber2015-07-011-5/+1
| | | | | Replace the extend function with an allocator since this fits better to the current use case.
* score: Simplify <rtems/score/thread.h>Sebastian Huber2015-06-251-0/+1
| | | | | | Avoid Thread_Control typedef in <rtems/score/percpu.h>. This helps to get rid of the <rtems/score/percpu.h> include in <rtems/score/thread.h> which exposes a lot of implementation details.
