2017-10-24score: Move thread queue timeout handlingSebastian Huber1-1/+0
Update #3117. Update #3182.
2017-10-24score: Rename function threadq support functionSebastian Huber1-1/+1
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.
2017-10-05posix: Implement self-contained POSIX rwlocksSebastian Huber1-3/+4
POSIX rwlocks are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3115.
2017-01-31score: Add _Thread_queue_Object_nameSebastian Huber1-1/+1
Add the special thread queue name _Thread_queue_Object_name to mark thread queues embedded in an object with identifier. Using the special thread state STATES_THREAD_QUEUE_WITH_IDENTIFIER is not reliable for this purpose since the thread wait information and thread state are protected by different SMP locks in separate critical sections. Remove STATES_THREAD_QUEUE_WITH_IDENTIFIER. Add and use _Thread_queue_Object_initialize(). Update #2858.
2017-01-11score: Add STATES_THREAD_QUEUE_WITH_IDENTIFIERSebastian Huber1-1/+1
Add thread state bit to identify thread queues that are embedded in an object with identifier.
2016-11-24score: Optimize _Thread_queue_Enqueue()Sebastian Huber1-1/+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.
2016-11-23score: Rename _Thread_queue_Enqueue_critical()Sebastian Huber1-1/+1
Delete unused _Thread_queue_Enqueue() and rename _Thread_queue_Enqueue_critical() to _Thread_queue_Enqueue().
2016-11-23score: Add thread queue enqueue calloutSebastian Huber1-1/+1
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.
2016-07-25cpukit: Add and use Watchdog_Discipline.Gedare Bloom1-2/+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
2016-05-30score: _CORE_mutex_Check_dispatch_for_seize()Sebastian Huber1-1/+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().
2016-05-26score: Add Status_Control for all APIsSebastian Huber1-8/+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.
2016-05-25score: Move thread queue MP callout to contextSebastian Huber1-9/+9
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.
2016-04-22score: Avoid Giant lock for CORE rwlockSebastian Huber1-40/+38
Update #2555.
2016-04-21score: Rename _CORE_RWLock_Obtain()Sebastian Huber1-1/+1
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.
2016-04-06score: Delete MP support for RW locksSebastian Huber1-3/+1
MP support was not implemented.
2016-04-06score: Delete Thread_Wait_information::idSebastian Huber1-1/+0
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.
2016-03-29score: Remove Thread_queue_Queue::operations fieldSebastian Huber1-1/+1
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.
2015-07-23score: Introduce Thread_queue_QueueSebastian Huber1-1/+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.
2015-05-19score: Delete Thread_queue_Control::timeout_statusSebastian Huber1-0/+1
Use a parameter for _Thread_queue_Enqueue() instead to reduce memory usage.
2015-05-19score: Add Thread_queue_Control::LockSebastian Huber1-12/+10
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: Delete Thread_queue_Control::stateSebastian Huber1-0/+2
Use a parameter for _Thread_queue_Enqueue() instead to reduce memory usage.
2015-04-22score: Delete _CORE_RWLock_Timeout()Sebastian Huber1-4/+2
This function was identical to _Thread_queue_Timeout(). This makes _Thread_queue_Enqueue_with_handler() obsolete.
2014-03-21Change all references of rtems.com to rtems.org.Chris Johns1-1/+1
2013-08-23score: _Thread_queue_Enqueue_with_handler()Sebastian Huber1-0/+1
Add thread parameter to _Thread_queue_Enqueue_with_handler() to avoid access to global _Thread_Executing.
2013-07-26score: Create threadq implementation headerSebastian Huber1-2/+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.
2013-07-26score: Create states implementation headerSebastian Huber1-1/+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.
2013-07-22score: Avoid direct usage of _Thread_ExecutingSebastian Huber1-1/+1
Pass the executing thread as a function parameter. Obtain the executing thread inside a thread dispatch critical section to avoid problems on SMP.
2013-07-22score: Create rwlock implementation headerSebastian Huber1-1/+1
Move implementation specific parts of corerwlock.h and corerwlock.inl into new header file corerwlockimpl.h. The corerwlock.h contains now only the application visible API.
2012-11-28score misc: Clean up Doxygen (GCI 2012)Alex Ivanov1-16/+7
This patch is a task from GCI 2012 which improves the Doxygen comments in the RTEMS source. https://google-melange.appspot.com/gci/task/view/google/gci2012/7978208
2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill1-2/+0
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.
