* mpci: Fix _MPCI_Enqueue_callout()Sebastian Huber2018-03-221-1/+2
| | | | | Update #3117. Update #3182.
* mpci: Update due to thread queue API changesSebastian Huber2018-03-221-6/+7
| | | | | Update #3117. Update #3182.
* score: Introduce _Internal_error()Sebastian Huber2016-12-121-7/+4
|
* score: Remove fatal is internal indicatorSebastian Huber2016-12-091-16/+3
| | | | | | | | | The fatal is internal indicator is redundant since the fatal source and error code uniquely identify a fatal error. Keep the fatal user extension is internal parameter for backward compatibility and set it to false always. Update #2825.
* score: Optimize _Thread_queue_Enqueue()Sebastian Huber2016-11-241-1/+4
| | | | | | | | | Move thread state for _Thread_queue_Enqueue() to the thread queue context. This reduces the parameter count of _Thread_queue_Enqueue() from five to four (ARM for example has only four function parameter registers). Since the thread state is used after several function calls inside _Thread_queue_Enqueue() this parameter was saved on the stack previously.
* score: Rename _Thread_queue_Enqueue_critical()Sebastian Huber2016-11-231-1/+1
| | | | | Delete unused _Thread_queue_Enqueue() and rename _Thread_queue_Enqueue_critical() to _Thread_queue_Enqueue().
* score: Add thread queue enqueue calloutSebastian Huber2016-11-231-27/+39
| | | | | | | Replace the expected thread dispatch disable level with a thread queue enqueue callout. This enables the use of _Thread_Dispatch_direct() in the thread queue enqueue procedure. This avoids impossible exection paths, e.g. Per_CPU_Control::dispatch_necessary is always true.
* mpci: Use the first scheduler for MPCISebastian Huber2016-11-091-1/+1
| | | | Avoid use of processor index 0 which may have no scheduler assigned.
* score: Introduce _Thread_Get_priority()Sebastian Huber2016-09-081-1/+1
| | | | Avoid direct access to thread internal data fields.
* score: Introduce Thread_queue_Lock_contextSebastian Huber2016-09-081-2/+2
| | | | | | Introduce Thread_queue_Lock_context to contain the context necessary for thread queue lock and thread wait lock acquire/release operations to reduce the Thread_Control size.
* cpukit: Add and use Watchdog_Discipline.Gedare Bloom2016-07-251-1/+2
| | | | | | | | | 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 semaphore variantsSebastian Huber2016-05-301-2/+9
|
* score: _CORE_mutex_Check_dispatch_for_seize()Sebastian Huber2016-05-301-1/+2
| | | | | | | | | | | Move the safety check performed by _CORE_mutex_Check_dispatch_for_seize() out of the performance critical path and generalize it. Blocking on a thread queue with an unexpected thread dispatch disabled level is illegal in all system states. Add the expected thread dispatch disable level (which may be 1 or 2 depending on the operation) to Thread_queue_Context and use it in _Thread_queue_Enqueue_critical().
* score: Add _Thread_queue_Context_set_MP_callout()Sebastian Huber2016-05-301-1/+1
| | | | | | Add _Thread_queue_Context_set_MP_callout() to simplify _Thread_queue_Context_initialize(). This makes it possible to more easily add additional fields to Thread_queue_Context.
* score: Add Status_Control for all APIsSebastian Huber2016-05-261-8/+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.
* Fix semaphore post overflow statusSebastian Huber2016-05-261-1/+1
| | | | Close #2720.
* score: Move thread queue MP callout to contextSebastian Huber2016-05-251-9/+10
| | | | | | | | 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 Huber2016-05-251-1/+1
| | | | | Get rid of the mp_id parameter used for some thread queue methods. Use THREAD_QUEUE_QUEUE_TO_OBJECT() instead.
* score: _CORE_semaphore_Seize()Sebastian Huber2016-05-201-1/+0
| | | | Delete unused parameter.
* Replace *_Get_interrupt_disable() with *_Get()Sebastian Huber2016-05-201-1/+1
| | | | | Uniformly use *_Get() to get an object by identifier with a lock context.
* score: Avoid Giant lock for _Thread_Start()Sebastian Huber2016-05-201-2/+4
| | | | Update #2555.
* mpci: Avoid Giant lock in _MPCI_Process_response()Sebastian Huber2016-05-041-17/+15
| | | | | Update #2555. Update #2703.
* score: Delete Thread_Wait_information::idSebastian Huber2016-04-061-1/+1
| | | | | | | | | | | 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: Allow MPCI packet receive function to blockSebastian Huber2016-03-291-0/+2

* score: Use constant for maximum count of CORE semaSebastian Huber2016-03-291-1/+0
|
* score: Remove Thread_queue_Queue::operations fieldSebastian Huber2016-03-291-10/+5
| | | | | | | | | 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.
* mpci: Avoid Giant lockSebastian Huber2016-03-181-8/+11
| | | | Update #2555.
* score: Avoid SCORE_EXTERNSebastian Huber2016-02-171-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | Delete SCORE_INIT. This finally removes the some.h: #ifndef SOME_XYZ_EXTERN #define SOME_XYZ_EXTERN extern #endif SOME_XYZ_EXTERN type xyz; some_xyz.c: #define SOME_XYZ_EXTERN #include <some.h> pattern in favour of some.h: extern type xyz; some_xyz.c #include <some.h> type xyz; Update #2559.
* Use linker set for MPCI initializationSebastian Huber2016-02-031-5/+72
| | | | Update #2408.
* mpci: Fix warningSebastian Huber2016-01-261-2/+0
| | | | Assignment is superfluous due to later call to _Thread_queue_Enqueue().
* mpci: Update due to API changesSebastian Huber2016-01-261-13/+12
| | | | | | | Update due to API changes introduced by ccd54344d904b657123e4e4ba795a32212382be2. Update #2514.
* score: Delete _CORE_semaphore_Seize()Sebastian Huber2015-05-191-3/+4
| | | | Rename _CORE_semaphore_Seize_isr_disable() to _CORE_semaphore_Seize().
* score: Fine grained locking for semaphoresSebastian Huber2015-05-191-3/+4
| | | | Update #2273.
* score: Delete Thread_queue_Control::timeout_statusSebastian Huber2015-05-191-4/+5
| | | | | Use a parameter for _Thread_queue_Enqueue() instead to reduce memory usage.
* score: Add Thread_queue_Control::LockSebastian Huber2015-05-191-2/+0
| | | | | | | | | | | Move the complete thread queue enqueue procedure into _Thread_queue_Enqueue_critical(). It is possible to use the thread queue lock to protect state of the object embedding the thread queue. This enables per object fine grained locking in the future. Delete _Thread_queue_Enter_critical_section(). Update #2273.
* score: _Thread_queue_Extract()Sebastian Huber2015-05-191-1/+1
| | | | | Remove thread queue parameter from _Thread_queue_Extract() since the current thread queue is stored in the thread control block.
* score: Delete Thread_queue_Control::stateSebastian Huber2015-04-231-4/+1
| | | | | Use a parameter for _Thread_queue_Enqueue() instead to reduce memory usage.

| | | | Rename _Internal_error_Occurred() into _Terminate().
* score: _Thread_queue_Enqueue_with_handler()Sebastian Huber2013-08-231-8/+14
| | | | | Add thread parameter to _Thread_queue_Enqueue_with_handler() to avoid access to global _Thread_Executing.
* score: Create mpci implementation headerSebastian Huber2013-07-261-12/+4
| | | | | Move implementation specific parts of mpci.h into new header file mpciimpl.h. The mpci.h contains now only the application visible API.
* score: Create threadq implementation headerSebastian Huber2013-07-261-2/+2
| | | | | | | | 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 states implementation headerSebastian Huber2013-07-261-1/+0
| | | | | | Move implementation specific parts of states.h and states.inl into new header file statesimpl.h. The states.h contains now only the application visible API.
* score: Create thread implementation headerSebastian Huber2013-07-261-1/+1
| | | | | | | | Move implementation specific parts of thread.h and thread.inl into new header file threadimpl.h. The thread.h contains now only the application visible API. Remove superfluous header file includes from various files.
* score: Avoid direct usage of _Thread_ExecutingSebastian Huber2013-07-221-2/+8
| | | | | | 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 semaphore implementation headerSebastian Huber2013-07-221-1/+1
| | | | | | Move implementation specific parts of coresem.h and coresem.inl into new header file coresemimpl.h. The coresem.h contains now only the application visible API.
