* testsuites/sptests/sp[g-r]*: Change license to BSD-2Joel Sherrill2022-04-051-3/+22
| | | | Updates #3053.
* bsps/testsuites/: Scripted embedded brains header file clean upJoel Sherrill2022-03-101-6/+0
| | | | Updates #4625.
* rtems: Require RTEMS_PRIORITY for MrsP semaphoresSebastian Huber2021-03-161-9/+14
| | | | | | | | | MrsP semaphores are a generalization of the priority ceiling semaphores for SMP configurations. Priority ceiling semaphores are required to use the priority task wait queue discipline. Require this discipline also for MrsP semaphores. Close #4347.
* Canonicalize config.h includeSebastian Huber2020-04-161-1/+1
| | | | | | | | Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
* config: Remove CONFIGURE_DISABLE_SMP_CONFIGURATIONSebastian Huber2020-02-251-2/+0
| | | | | | | | | | The CONFIGURE_DISABLE_SMP_CONFIGURATION configuration option and rtems_configuration_is_smp_enabled() were added during the SMP support development cycle as a workaround to fix some testsuite failures in SMP configurations. All use cases were replaced with tests for specific conditions. The configuration option and test macro were undocumented. Close #3876.
* rtems: Simplify semaphore configurationSebastian Huber2019-12-111-1/+0
| | | | | | | | | | | | | | | The MrsP semaphore implementation predates the addition of self-contained synchronization objects. At this time, the potential memory reduction was justified considering the more complex configuration and additional use of the workspace. With the availability of self-contained synchronization options, e.g. POSIX mutexes, this is no longer justified. Memory constrained applications should use the self-contained synchronization objects. Remove the CONFIGURE_MAXIMUM_MRSP_SEMAPHORES configuration option. This has only an impact on applications which use SMP and a large number of scheduler instances. Update #3833.
* tests: Use rtems_task_exit()Sebastian Huber2018-10-051-1/+1
| | | | Update #3533.
* testsuite/sptests: 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
* 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.
* confdefs.h: CONFIGURE_DISABLE_SMP_CONFIGURATIONSebastian Huber2017-05-111-0/+2
| | | | | | | | | | | Enable the SMP configuration by default in case SMP is enabled. Add configuration option CONFIGURE_DISABLE_SMP_CONFIGURATION to disable it explicitly. Add CONFIGURE_DISABLE_SMP_CONFIGURATION to all test which would fail otherwise. Update #3001.
* rtems: Rework RTEMS API to SuperCore prioritySebastian Huber2016-06-221-0/+13
| | | | | Use same structure as POSIX API for thread priority conversion to/from SuperCore.
* Delete CONFIGURE_USE_IMFS_AS_BASE_FILESYSTEMSebastian Huber2014-12-161-2/+0
| | | | This define was superfluous, undocumented and used inconsistently.
* tests: Add documentationSebastian Huber2014-09-011-2/+15

* score: Multiprocessor Resource Sharing ProtocolSebastian Huber2014-05-284-0/+368
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.
