This change is part of the testsuite Makefile.am reorganization. Update #3382
2017-11-20score: Optimize scheduler priority updatesSebastian Huber1-5/+10
Thread priority changes may append or prepend the thread to its priority group on the scheduler ready queue. Previously, a separate priority value and a prepend-it flag in the scheduler node were used to propagate a priority change to the scheduler. Now, use an append-it bit in the priority control and reduce the plain priority value to 63 bits. This change leads to a significant code size reduction (about 25%) of the SMP schedulers. The negligible increase of the standard priority scheduler is due to some additional shift operations (SCHEDULER_PRIORITY_MAP() and SCHEDULER_PRIORITY_UNMAP()).

2017-11-06tests: Use simple console driverSebastian Huber1-1/+1
Update #3170. Update #3199.
2017-10-28tests: Remove TEST_INITSebastian Huber1-2/+0
The TEST_EXTERN is a used only by the system.h style tests and they use CONFIGURE_INIT appropriately. Update #3170. Update #3199.
2017-10-23testsuite: Use printk for all test output where possible.Chris Johns1-0/+2
- Remove the printf support leaving the direct printk support configured with TESTS_USE_PRINTK and all other output goes via a buffered vsniprintf call to printk. - Control the test's single init for functions and global data with TEST_INIT and not CONFIGURE_INIT. They are now separate. Updates #3170.
2016-06-24sptests/spintrcritical23: Explicity set schedulerSebastian Huber1-0/+3
This test uses scheduler-specific data structures, thus it must use the right scheduler.
2016-06-22score: Add thread priority to scheduler nodesSebastian Huber1-48/+9
The thread priority is manifest in two independent areas. One area is the user visible thread priority along with a potential thread queue. The other is the scheduler. Currently, a thread priority update via _Thread_Change_priority() first updates the user visble thread priority and the thread queue, then the scheduler is notified if necessary. The priority is passed to the scheduler via a local variable. A generation counter ensures that the scheduler discards out-of-date priorities. This use of a local variable ties the update in these two areas close together. For later enhancements and the OMIP locking protocol implementation we need more flexibility. Add a thread priority information block to Scheduler_Node and synchronize priority value updates via a sequence lock on SMP configurations. Update #2556.
2016-05-20Replace *_Get_interrupt_disable() with *_Get()Sebastian Huber1-1/+1
Uniformly use *_Get() to get an object by identifier with a lock context.
2016-05-20testsuites: Replace _Thread_Get()Sebastian Huber1-5/+4
Replace _Thread_Get() with _Thread_Get_interrupt_disable() to avoid the Giant lock. Update #2555.
2015-05-19score: Add Thread_queue_OperationsSebastian Huber1-2/+2
Replace the Thread_Priority_control with more general Thread_queue_Operations which will be used for generic priority change, timeout, signal and wait queue operations in the future. Update #2273.
2015-03-24score: Add thread priority change handlerSebastian Huber1-2/+2
Since the thread current priority change and thread queue requeue is performed in one critical section it is possible to simplify the thread queue requeue procedure. Add a thread queue agnostic thread priority change handler so that we are able to use alternative thread queue implementations. Update #2273.
2015-03-21sptests/spintrcritical23: Fix warningsSebastian Huber1-8/+10
2015-03-20Replace www.rtems.com with www.rtems.orgSebastian Huber1-1/+1
2015-03-20score: Fix _Thread_Change_priority()Sebastian Huber4-0/+223
Atomically update the current priority of a thread and the wait queue. Serialize the scheduler update in a separate critical section with a generation number. New test sptests/spintrcritical23. Close #2310.
