2023-05-20Update company nameSebastian Huber1-1/+1
The embedded brains GmbH & Co. KG is the legal successor of embedded brains GmbH.
2023-02-14doxygen: Use @anchor for appl config optionsSebastian Huber1-5/+5
The application configuration options are documented in "cpukit/doxygen/appl-config.h". Since the application configuration option defines are also present in multiple test program sources, the "#OPTION" references cannot be mapped to a unique definition. Add an anchor for each option and reference it to avoid the issues with the multiple definitions. Update #3994.

2021-04-07rtems: Fix rtems_semaphore_release() documentationSebastian Huber1-1/+1
The directive returns RTEMS_UNSATISFIED if the semaphore's count already had the maximum value of UINT32_MAX.
2021-03-16rtems: Allow initially locked MrsP semaphoresSebastian Huber1-3/+0
Rejecting initially locked MrsP semaphores was due to a limitiation of the early limitiation of the MrsP protocol. This limitation no longer exists.
2021-03-16rtems: Require RTEMS_PRIORITY for MrsP semaphoresSebastian Huber1-1/+2
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.
2021-02-24rtems: Move rtems_task_priority definitionSebastian Huber1-1/+0
This type is not only used by Task Manager directives. This is a preparation to move the rtems_scheduler_*() directives from <rtems/rtems/tasks.h> to a new <rtems/rtems/scheduler.h>.

2018-01-25Remove make preinstallChris Johns1-0/+0
A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.

Move MrsP semaphore operations to a less prominent location. Fix field name.
2016-05-30score: Rework CORE inherit priority mutexSebastian Huber1-7/+0
Provide dedicated seize and surrender methods for inherit priority mutexes. This eliminates CORE_mutex_Attributes.
2016-05-30score: Add CORE mutex variantsSebastian Huber1-1/+1
Add CORE_recursive_mutex_Control and CORE_ceiling_mutex_Control to avoid the run-time evaluation of attributes to figure out how a particular mutex methods should behave. Start with the no protocol variants. This eliminates the CORE_MUTEX_DISCIPLINES_FIFO and CORE_MUTEX_DISCIPLINES_PRIORITY disciplines.

2016-05-30rtems: Simplify rtems_semaphore_delete()Sebastian Huber1-0/+5
2016-04-06score: Delete Thread_Wait_information::idSebastian Huber1-7/+7
This field was only by the monitor in non-multiprocessing configurations. Add new field Thread_Wait_information::remote_id in multiprocessing configurations and use it for the remote procedure call thread queue. Add _Thread_Wait_get_id() to obtain the object identifier for debug and system information tools. Ensure the object layout via static asserts. Add test cases to sptests/spthreadq01.

2014-05-28score: Multiprocessor Resource Sharing ProtocolSebastian Huber1-0/+46
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.
