2023-05-20Update company nameSebastian Huber1-1/+1
The embedded brains GmbH & Co. KG is the legal successor of embedded brains GmbH.
2022-02-28score/src/[t-z]*.c: Change license to BSD-2Joel Sherrill1-3/+22
Updates #3053.
2021-11-23score: Move _Thread_queue_Extract()Sebastian Huber1-0/+57
Move _Thread_queue_Extract() since this function is not used by the core services (threads, semaphores, mutexes, message queues). Update #4546.
2015-03-22score: Move _Thread_queue_Extract()Sebastian Huber1-71/+0
Move _Thread_queue_Dequeue(). We need all or no thread queue functions so it makes no sense to have them in separate modules. One module enables compiler optimizations without link-time optimization. Make _Thread_blocking_operation_Finalize() static since it is use now only in one module.
2014-07-15Use Shared Method for Thread Unblock CleanupJoel Sherrill1-16/+6
When a thread is removed from a thread queue or is unblocked by receiving an event, the same actions are required. + timeout watchdog canceled, + thread must be unblocked, and + (MP only) proxy cleaned up This patch makes sure there is only one copy of this code.
2014-07-15Thread Queue: Merge discipline subroutines into main methodsJoel Sherrill1-9/+39
There was a lot of duplication between the discipline subroutines. With the transition to RBTrees for priority discipline, there were only a few lines of source code manipulating the data structure for FIFO and priority. Thus is made sense to fold these back into the main methods. As part of doing this all of the tests for discipline were changed to be in the same order.
2014-04-01score: PR2172: _Thread_queue_Extract()Sebastian Huber1-4/+17
Add _Thread_queue_Extract_with_return_code(). On SMP this sequence in _Thread_queue_Process_timeout() was broken: [...] /* * After we enable interrupts here, a lot may happen in the * meantime, e.g. nested interrupts may release the resource that * times out here. So we enter _Thread_queue_Extract() * speculatively. Inside this function we check the actual status * under ISR disable protection. This ensures that exactly one * executing context performs the extract operation (other parties * may call _Thread_queue_Dequeue()). If this context won, then * we have a timeout. * * We can use the_thread_queue pointer here even if * the_thread->Wait.queue is already set to NULL since the extract * operation will only use the thread queue discipline to select * the right extract operation. The timeout status is set during * thread queue initialization. */ we_did_it = _Thread_queue_Extract( the_thread_queue, the_thread ); if ( we_did_it ) { the_thread->Wait.return_code = the_thread_queue->timeout_status; } [...] In case _Thread_queue_Extract() successfully extracted a thread, then this thread may start execution on a remote processor immediately and read the the_thread->Wait.return_code before we update it here with the timeout status. Thus it observes a successful operation even if it timed out.

2013-08-26score: PR2140: _Thread_queue_Extract()Sebastian Huber1-3/+3
Return if the executing context performed the extract operation since interrupts may interfere.
2013-07-26score: Create threadq implementation headerSebastian Huber1-7/+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.

This patch is a task from GCI 2012 which improves the Doxygen comments in the RTEMS source. http://www.google-melange.com/gci/task/view/google/gci2012/7976215
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.
