2020-04-28doxygen: Switch @brief and @ingroupSebastian Huber
This order change fixes the Latex documentation build via Doxygen.
2020-04-16Canonicalize config.h includeSebastian Huber
Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
2018-02-08Use _Thread_Dispatch_direct()Sebastian Huber
Use _Thread_Dispatch_direct() for operations that block the executing thread. This ensures that we get a fatal error (INTERNAL_ERROR_BAD_THREAD_DISPATCH_DISABLE_LEVEL) if we try to block in an invalid context, e.g. during system start or an interrupt handler.
2017-10-24score: Move thread queue timeout handlingSebastian Huber
Update #3117. Update #3182.
2017-10-24score: Rename function threadq support functionSebastian Huber
Rename _Thread_queue_Context_set_do_nothing_enqueue_callout() into _Thread_queue_Context_set_enqueue_do_nothing_extra(). More _Thread_queue_Context_set_enqueue_*() functions will follow. Update #3117. Update #3182.
2016-11-23score: Add thread queue enqueue calloutSebastian Huber
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.
2016-09-08score: Introduce Thread_queue_Lock_contextSebastian Huber
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.
2016-07-25cpukit: Add and use Watchdog_Discipline.Gedare Bloom
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
2016-05-30score: _CORE_mutex_Check_dispatch_for_seize()Sebastian Huber
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().
2016-05-26score: Add Status_Control for all APIsSebastian Huber
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.
2016-05-20Replace *_Get_interrupt_disable() with *_Get()Sebastian Huber
Uniformly use *_Get() to get an object by identifier with a lock context.
2016-05-20posix: Rework pthread_join()Sebastian Huber
Rework pthread_join() to use _Thread_Join(). Close #2402. Update #2555. Update #2626. Close #2714.
2016-03-29score: Remove Thread_queue_Queue::operations fieldSebastian Huber
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.
2015-05-19score: Delete Thread_queue_Control::timeout_statusSebastian Huber
Use a parameter for _Thread_queue_Enqueue() instead to reduce memory usage.
2015-05-19score: Add Thread_queue_Control::LockSebastian Huber
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.
2015-04-23score: Fix POSIX thread joinSebastian Huber
A thread join is twofold. There is one thread that exists and an arbitrary number of threads that wait for the thread exit (one-to-many relation). The exiting thread may want to wait for a thread that wants to join its exit (STATES_WAITING_FOR_JOIN_AT_EXIT in _POSIX_Thread_Exit()). On the other side we need a thread queue for all the threads that wait for the exit of one particular thread (STATES_WAITING_FOR_JOIN in pthread_join()). Update #2035.
2015-04-23score: Delete Thread_queue_Control::stateSebastian Huber
Use a parameter for _Thread_queue_Enqueue() instead to reduce memory usage.
2014-05-15score: Simplify _Thread_Change_priority()Sebastian Huber
The function to change a thread priority was too complex. Simplify it with a new scheduler operation. This increases the average case performance due to the simplified logic. The interrupt disabled critical section is a bit prolonged since now the extract, update and enqueue steps are executed atomically. This should however not impact the worst-case interrupt latency since at least for the Deterministic Priority Scheduler this sequence can be carried out with a wee bit of instructions and no loops. Add _Scheduler_Change_priority() to replace the sequence of - _Thread_Set_transient(), - _Scheduler_Extract(), - _Scheduler_Enqueue(), and - _Scheduler_Enqueue_first(). Delete STATES_TRANSIENT, _States_Is_transient() and _Thread_Set_transient() since this state is now superfluous. With this change it is possible to get rid of the SCHEDULER_SMP_NODE_IN_THE_AIR state. This considerably simplifies the implementation of the new SMP locking protocols.

2014-02-03posix/*.c: Remove use of register keywordJoel Sherrill
2013-08-23score: _Thread_queue_Enqueue_with_handler()Sebastian Huber
Add thread parameter to _Thread_queue_Enqueue_with_handler() to avoid access to global _Thread_Executing.
2013-07-26score: Create threadq implementation headerSebastian Huber
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.
2013-07-26score: Create thread implementation headerSebastian Huber
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.
2013-07-22posix: Obtain _Thread_Executing in proper contextSebastian Huber
2013-07-22posix: Create pthread implementation headerSebastian Huber
Move implementation specific parts of pthread.h and pthread.inl into new header file pthreadimpl.h. The pthread.h contains now only the application visible API.
2013-07-22posix: Include missing header filesSebastian Huber
2013-06-07score: Add and use _Objects_Put()Sebastian Huber
Add and use _Objects_Put_without_thread_dispatch(). These two functions pair with the _Objects_Get() function. This helps to introduce object specific SMP locks to avoid lock contention.

2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill
Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.

PR 1855/cpukit * posix/src/psignal.c, posix/src/pthread.c, posix/src/pthreadjoin.c: Correct signal processing during pthread_join. We are supposed to unblock the thread waiting on a pthread_join(), dispatch the signal handler, account for it potentially overwriting errno, and then have the thread return to blocking within pthread_join().
