* timecounter: Use in RTEMSAlexander Krutwig2015-05-201-2/+0

| | | | | | | Add a thread wait timeout code. Replace _Event_Timeout() with a general purpose _Thread_Timeout() watchdog handler. Update #2273.
* score: Implement fine-grained locking for eventsSebastian Huber2015-03-051-1/+0
| | | | | | | Use the ISR lock of the thread object to protect the event state and use the Giant lock only for the blocking operations. Update #2273.

* score: Multiprocessor Resource Sharing ProtocolSebastian Huber2014-05-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | Add basic support for the Multiprocessor Resource Sharing Protocol (MrsP). The Multiprocessor Resource Sharing Protocol (MrsP) is defined in A. Burns and A.J. Wellings, A Schedulability Compatible Multiprocessor Resource Sharing Protocol - MrsP, Proceedings of the 25th Euromicro Conference on Real-Time Systems (ECRTS 2013), July 2013. It is a generalization of the Priority Ceiling Protocol to SMP systems. Each MrsP semaphore uses a ceiling priority per scheduler instance. These ceiling priorities can be specified with rtems_semaphore_set_priority(). A task obtaining or owning a MrsP semaphore will execute with the ceiling priority for its scheduler instance as specified by the MrsP semaphore object. Tasks waiting to get ownership of a MrsP semaphore will not relinquish the processor voluntarily. In case the owner of a MrsP semaphore gets preempted it can ask all tasks waiting for this semaphore to help out and temporarily borrow the right to execute on one of their assigned processors. The help out feature is not implemented with this patch.

* rtems: Rename rtems_smp_get_current_processor()Sebastian Huber2014-04-111-0/+1
| | | | | | | Rename rtems_smp_get_current_processor() in rtems_get_current_processor(). Make rtems_get_current_processor() a function in uni-processor configurations to enable ABI compatibility with SMP configurations.

| | | | | | Rename rtems_smp_get_processor_count() in rtems_get_processor_count(). Make rtems_get_processor_count() a function in uni-processor configurations to enable ABI compatibility with SMP configurations.
* Disable per task variables when SMP is enabledJoel Sherrill2014-04-041-0/+3
| | | | | | Per task variables are inherently unsafe in SMP systems. This patch disables them from the build and adds warnings in the appropriate documentation and configuration sections.
* score: PR2152: Use allocator mutex for objectsSebastian Huber2014-03-311-1/+0
| | | | | Use allocator mutex for objects allocate/free. This prevents that the thread dispatch latency depends on the workspace/heap fragmentation.

* rtems: Add system eventsSebastian Huber2012-10-301-0/+2
| | | | | | | System events are similar to normal events. They offer a second set of events. These events are intended for internal RTEMS use and should not be used by applications (with the exception of the transient system event).
* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-111-4/+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.

* Add functions for greedy workspace allocationSebastian Huber2012-02-171-0/+1
| | | | | | | Various tests must check program paths that result due to failed memory allocations from the workspace. To avoid tinkering with internal workspace structures throughout the test code these functions should be used.
* PR 1991/cpukit - attr.c (really mode code) warning reworkJoel Sherrill2012-02-021-1/+1
| | | | | | | | | | | | | | This PR was about a warning for no previous prototype for rtems_interrupt_level_attribute. This method exists (like a few others) to have real bodies for Classic API services implemented as macros. These macros are not available from anything but C and C++. The most explicit use was in the Ada binding but these would be needed from assembly language or any other non-C based language. On top of needing a prototype, the methods were misnamed. They were related to modes. This renames them, moves the file, fixes test code, etc.
