* 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 Huber2016-11-231-1/+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.
* posix: Fix timeout handling in sigtimedwait()Sebastian Huber2016-10-311-4/+7
| | | | Update #2798.
* cpukit: Add and use Watchdog_Discipline.Gedare Bloom2016-07-251-1/+1
| | | | | | | | | 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: _CORE_mutex_Check_dispatch_for_seize()Sebastian Huber2016-05-301-12/+14
| | | | | | | | | | | 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 Status_Control for all APIsSebastian Huber2016-05-261-9/+13
| | | | | | | | | | | 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.
* posix: Remove superfluous thread dispatch disableSebastian Huber2016-05-021-14/+12
| | | | | | | The _Thread_queue_Enqueue_critical() already deals with thread dispatching. Update #2555.
* score: Remove Thread_queue_Queue::operations fieldSebastian Huber2016-03-291-1/+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.
* score: Rename _POSIX_Absolute_timeout_to_ticks()Sebastian Huber2015-07-281-1/+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_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: Delete Thread_queue_Control::timeout_statusSebastian Huber2015-05-191-0/+1
| | | | | Use a parameter for _Thread_queue_Enqueue() instead to reduce memory usage.
* score: Add Thread_queue_Control::LockSebastian Huber2015-05-191-5/+3
| | | | | | | | | | | 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: Delete Thread_queue_Control::stateSebastian Huber2015-04-231-1/+6
| | | | | Use a parameter for _Thread_queue_Enqueue() instead to reduce memory usage.
* Change all references of rtems.com to rtems.org.Chris Johns2014-03-211-1/+1

* score: Add local context to SMP lock APISebastian Huber2014-03-111-5/+5
| | | | | | | | | | | Add a local context structure to the SMP lock API for acquire and release pairs. This context can be used to store the ISR level and profiling information. It may be later used to enable more sophisticated lock algorithms, e.g. MCS locks. There is only one lock that cannot be used with a local context. This is the per-CPU lock since here we would have to transfer the local context through a context switch which is very complicated.
* signal methods: Add restrict keywordBryan Dunsmore2013-11-291-3/+3

* posix: Add and use _POSIX_signals_Acquire()Sebastian Huber2013-08-271-6/+14
| | | | | | Add and use _POSIX_signals_Release(). The post-switch handler is not protected by disabled thread dispatching. Use proper SMP lock for signal management.
* score: _Thread_queue_Enqueue_with_handler()Sebastian Huber2013-08-231-1/+1
| | | | | Add thread parameter to _Thread_queue_Enqueue_with_handler() to avoid access to global _Thread_Executing.
* score: Create threadq implementation headerSebastian Huber2013-07-261-2/+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.
* posix: Create pthread implementation headerSebastian Huber2013-07-221-1/+1

Some of these services incorrectly took a timeout as a relative time. Others would compute a 0 delta to timeout if the absolute time and the current time were equal and thus incorrectly block the caller forever. The root of the confusion is that POSIX specifies that if the timeout is incorrect (e.g. in the past, is now, or is numerically invalid), that it does not matter if the call would succeed without blocking. This is in contrast to RTEMS programming style where all errors are checked before any critical sections are entered. This fix implemented a more uniform way of handling POSIX absolute time timeouts. + pthread_cond_timedwait - could block forever + mq_timedreceive - used relative not absolute time + mq_timedsend - used relative not absolute time + pthread_mutex_timedlock - used relative not absolute time + pthread_rwlock_timedrdlock- used relative not absolute time + pthread_rwlock_timedwrlock- used relative not absolute time + sem_timedwait - could block forever
