* testsuite/smptests: Merged nested Makefile.am files into one Makefile.amChris Johns2018-04-101-19/+0
| | | | | | This change is part of the testsuite Makefile.am reorganization. Update #3382
* score: Optimize scheduler priority updatesSebastian Huber2017-11-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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()).

* tests: Use simple console driverSebastian Huber2017-11-061-1/+1
| | | | | Update #3170. Update #3199.
* tests: Remove TEST_INITSebastian Huber2017-10-281-2/+0
| | | | | | | | The TEST_EXTERN is a used only by the system.h style tests and they use CONFIGURE_INIT appropriately. Update #3170. Update #3199.
* testsuite: Use printk for all test output where possible.Chris Johns2017-10-231-0/+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.
* smptests/smpscheduler01: Use right schedulerSebastian Huber2017-07-191-0/+3
| | | | Update #3063.
* Rename CONFIGURE_SMP_MAXIMUM_PROCESSORSSebastian Huber2017-02-141-1/+1
| | | | | | | Rename CONFIGURE_SMP_MAXIMUM_PROCESSORS to CONFIGURE_MAXIMUM_PROCESSORS since the SMP part is superfluous. Update #2894.
* Remove CONFIGURE_SMP_APPLICATIONSebastian Huber2017-02-021-2/+0
| | | | | | Enable the SMP support if CONFIGURE_SMP_MAXIMUM_PROCESSORS > 1. Update #2893.
* testsuites: Avoid Giant lockSebastian Huber2016-05-201-4/+6
| | | | | | | | | Replace _Thread_Disable_dispatch() with _Thread_Dispatch_disable(). Replace _Thread_Enable_dispatch() with _Thread_Dispatch_enable(). This is a preparation to remove the Giant lock. Update #2555.
* tests: Add documentationSebastian Huber2014-09-011-3/+2

* score: Collect scheduler related fields in TCBSebastian Huber2014-06-231-2/+3
| | | | | Add Thread_Scheduler_control to collect scheduler related fields of the TCB.
* rtems: Rename rtems_smp_get_processor_count()Sebastian Huber2014-04-111-1/+1
| | | | | | 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.
* smptests/smpschedule01: Rename in smpscheduler01Sebastian Huber2014-04-094-0/+247
