* score: Simplify thread queue acquire/releaseSebastian Huber2016-09-081-12/+3

* cpukit: Add and use Watchdog_Discipline.Gedare Bloom2016-07-251-10/+0
| | | | | | | | | Clock disciplines may be WATCHDOG_RELATIVE, WATCHDOG_ABSOLUTE, or WATCHDOG_NO_TIMEOUT. A discipline of WATCHDOG_RELATIVE with a timeout of WATCHDOG_NO_TIMEOUT is equivalent to a discipline of WATCHDOG_NO_TIMEOUT. updates #2732
* score: Add Status_Control for all APIsSebastian Huber2016-05-261-39/+6
| | | | | | | | | | | Unify the status codes of the Classic and POSIX API to use the new enum Status_Control. This eliminates the Thread_Control::Wait::timeout_code field and the timeout parameter of _Thread_queue_Enqueue_critical() and _MPCI_Send_request_packet(). It gets rid of the status code translation tables and instead uses simple bit operations to get the status for a particular API. This enables translation of status code constants at compile time. Add _Thread_Wait_get_status() to avoid direct access of thread internal data structures.
* score: Move thread queue MP callout to contextSebastian Huber2016-05-251-247/+94
| | | | | | | | 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 Huber2016-05-251-26/+0
| | | | | Get rid of the mp_id parameter used for some thread queue methods. Use THREAD_QUEUE_QUEUE_TO_OBJECT() instead.
* score: Fix blocking _CORE_message_queue_Submit()Sebastian Huber2016-05-241-3/+1
| | | | Close #2718.
* score: _CORE_message_queue_Seize()Sebastian Huber2016-05-241-3/+0
| | | | Delete unused parameter.
* score: Move message notificationSebastian Huber2016-05-021-6/+4
| | | | | | | | Move message notification to end of critical section and delegate the message queue release to the notification handler. It may do more complex notification actions out of the critical section. Update #2555.
* score: _CORE_message_queue_Insert_message()Sebastian Huber2016-05-021-6/+6
| | | | Move common code into _CORE_message_queue_Insert_message().
* score: _CORE_message_queue_Set_message_priority()Sebastian Huber2016-05-021-16/+0
| | | | | Remove _CORE_message_queue_Set_message_priority() and set the priority in _CORE_message_queue_Insert_message().
* score: _CORE_message_queue_Close()Sebastian Huber2016-05-021-7/+13
| | | | | | Move lock acquire to caller of _CORE_message_queue_Close() to allow state checks during object close operations under lock protection. Ensures deletion safety on uni-processor configuration.
* score: Simplify _CORE_message_queue_Close()Sebastian Huber2016-04-211-9/+2
| | | | | | | Drop status parameter since each caller used CORE_MESSAGE_QUEUE_STATUS_WAS_DELETED. Remove superfluous _CORE_message_queue_Flush().
* score: Rework MP thread queue callout supportSebastian Huber2016-04-061-97/+207
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: _Thread_queue_Flush() parameter changesSebastian Huber2016-04-061-7/+38
| | | | | | | | | | | | 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: Remove Thread_queue_Queue::operations fieldSebastian Huber2016-03-291-20/+10
| | | | | | | | | 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: Introduce Thread_queue_QueueSebastian Huber2015-07-231-1/+2
| | | | | | Separate the thread queue heads and lock from the operations. This enables the support for light weight objects which only support one queuing discipline.
* score: Fine grained locking for message queuesSebastian Huber2015-05-191-12/+109
| | | | | | | | | | | Aggregate several critical sections into a bigger one. Sending and receiving messages is now protected by an ISR lock. Thread dispatching is only disabled in case a blocking operation is necessary. The message copy procedure is done inside the critical section (interrupts disabled). Thus this change may have a negative impact on the interrupt latency in case very large messages are transferred. Update #2273.
* score: Delete _CORE_message_queue_Flush_support()Sebastian Huber2015-05-191-17/+0
| | | | | Check the number of pending messages in _CORE_message_queue_Flush() to avoid race conditions.
* score: Fix priority message queue insertSebastian Huber2015-04-231-31/+1
| | | | | | | | Move the linear search into a critical section to avoid corruption due to higher priority interrupts. The interrupt disable time depends now on the count of pending messages. Close #2328.
* cpukit: Remove old DESCRIPTION: in commentsJoel Sherrill2015-03-111-6/+0
| | | | These were remnants of pre-Doxygen comment style.

* score: Create threadq implementation headerSebastian Huber2013-07-261-0/+1
| | | | | | | | Move implementation specific parts of tqdata.h, threadq.h and threadq.inl into new header file threadqimpl.h. The threadq.h contains now only the application visible API. Delete tqdata.h.
* score: Create chain implementation headerSebastian Huber2013-07-221-0/+1
| | | | | | Move implementation specific parts of chain.h and chain.inl into new header file chainimpl.h. The chain.h contains now only the application visible API.
* score: Avoid direct usage of _Thread_ExecutingSebastian Huber2013-07-221-0/+4
| | | | | | Pass the executing thread as a function parameter. Obtain the executing thread inside a thread dispatch critical section to avoid problems on SMP.
* score: Create message queue implementation headerSebastian Huber2013-07-221-0/+577
Move implementation specific parts of coremsg.h and coremsg.inl into new header file coremsgimpl.h. The coremsg.h contains now only the application visible API.
