* score: Simplify _Watchdog_Tick()Sebastian Huber2016-02-171-0/+5
| | | | | | | Move thread dispatch disable check to legacy rtems_clock_tick(). Assert that thread dispatching is disabled in _Watchdog_Tick(). This is usually the case, since this function is called in interrupt context by the clock tick service routine.
* score: Fix simple timecounter supportSebastian Huber2016-01-191-1/+5
| | | | Update #2502.
* timecounter: Use in RTEMSAlexander Krutwig2015-05-201-12/+5
| | | | | | | | Replace timestamp implementation with FreeBSD bintime and timecounters. New test sptests/sptimecounter02. Update #2271.
* score: Remove Giant lock in rtems_clock_tick()Sebastian Huber2015-05-191-10/+1
| | | | Update #2307.
* score: Add clustered/partitioned schedulingSebastian Huber2014-04-151-1/+1
| | | | | | | | | | | | | | | Clustered/partitioned scheduling helps to control the worst-case latencies in the system. The goal is to reduce the amount of shared state in the system and thus prevention of lock contention. Modern multi-processor systems tend to have several layers of data and instruction caches. With clustered/partitioned scheduling it is possible to honour the cache topology of a system and thus avoid expensive cache synchronization traffic. We have clustered scheduling in case the set of processors of a system is partitioned into non-empty pairwise-disjoint subsets. These subsets are called clusters. Clusters with a cardinality of one are partitions. Each cluster is owned by exactly one scheduler instance.
* score: Add scheduler control to scheduler opsSebastian Huber2014-04-041-1/+1
| | | | | Scheduler operations must be free of a global scheduler context to enable partitioned/clustered scheduling.

* score: Per-CPU thread dispatch disable levelSebastian Huber2013-08-091-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use a per-CPU thread dispatch disable level. So instead of one global thread dispatch disable level we have now one instance per processor. This is a major performance improvement for SMP. On non-SMP configurations this may simplifiy the interrupt entry/exit code. The giant lock is still present, but it is now decoupled from the thread dispatching in _Thread_Dispatch(), _Thread_Handler(), _Thread_Restart_self() and the interrupt entry/exit. Access to the giant lock is now available via _Giant_Acquire() and _Giant_Release(). The giant lock is still implicitly acquired via _Thread_Dispatch_decrement_disable_level(). The giant lock is only acquired for high-level operations in interrupt handlers (e.g. release of a semaphore, sending of an event). As a side-effect this change fixes the lost thread dispatch necessary indication bug in _Thread_Dispatch(). A per-CPU thread dispatch disable level greatly simplifies the SMP support for the interrupt entry/exit code since no spin locks have to be acquired in this area. It is only necessary to get the current processor index and use this to calculate the address of the own per-CPU control. This reduces the interrupt latency considerably. All elements for the interrupt entry/exit code are now part of the Per_CPU_Control structure: thread dispatch disable level, ISR nest level and thread dispatch necessary. Nothing else is required (except CPU port specific stuff like on SPARC).
* score: Rename tod.h to todimpl.hSebastian Huber2013-08-011-1/+1

* score: Create thread implementation headerSebastian Huber2013-07-261-1/+1
| | | | | | | | Move implementation specific parts of thread.h and thread.inl into new header file threadimpl.h. The thread.h contains now only the application visible API. Remove superfluous header file includes from various files.
* score: Create scheduler implementation headerSebastian Huber2013-07-261-3/+1
| | | | | | Move implementation specific parts of scheduler.h and scheduler.inl into new header file schedulerimpl.h. The scheduler.h contains now only the application visible API.
* score: Create watchdog implementation headerSebastian Huber2013-07-221-1/+1
| | | | | | Move implementation specific parts of watchdog.h and watchdog.inl into new header file watchdogimpl.h. The watchdog.h contains now only the application visible API.
* score: Add and use _Thread_Dispatch_is_enabled()Sebastian Huber2013-06-141-1/+1
| | | | | Delete _Thread_Dispatch_in_critical_section() and _Thread_Is_dispatching_enabled().
* cpukit: Clean up Doxygen #3 (GCI 2012)Alex Ivanov2012-12-031-15/+7

* 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.
