* posix: Implement self-contained POSIX rwlocksSebastian Huber2017-10-051-6/+3
| | | | | | | | POSIX rwlocks are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3115.
* posix: cond_timedwait remember and use clock from condattrGedare Bloom2016-07-251-1/+1
| | | | updates #2745
* 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: Add Status_Control for all APIsSebastian Huber2016-05-261-19/+14
| | | | | | | | | | | 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 Huber2016-05-251-3/+3
| | | | | | | | 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: Avoid Giant lock for CORE rwlockSebastian Huber2016-04-221-53/+34
| | | | Update #2555.
* score: Rename _CORE_RWLock_Obtain()Sebastian Huber2016-04-211-1/+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.
* score: Delete MP support for RW locksSebastian Huber2016-04-061-3/+1
| | | | MP support was not implemented.
* score: Rename _POSIX_Absolute_timeout_to_ticks()Sebastian Huber2015-07-281-9/+9
| | | | | | 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: Create threadq implementation headerSebastian Huber2013-07-261-1/+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: Avoid direct usage of _Thread_ExecutingSebastian Huber2013-07-221-12/+15
| | | | | | Pass the executing thread as a function parameter. Obtain the executing thread inside a thread dispatch critical section to avoid problems on SMP.
* posix: Create rwlock implementation headerSebastian Huber2013-07-221-1/+1
| | | | | | Move implementation specific parts of rwlock.h and rwlock.inl into new header file rwlockimpl.h. The rwlock.h contains now only the application visible API.
* score: Add and use _Objects_Put()Sebastian Huber2013-06-071-1/+1
| | | | | | 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.

* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-111-2/+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.

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
