* Remove make preinstallChris Johns2018-01-251-120/+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.
* rtems: rtems_semaphore_flush() with prio inheritSebastian Huber2017-11-161-2/+6
| | | | | | | | | The _Semaphore_Get_operations() must return the proper operations for priority inheritance semaphores. Add a test case for rtems_semaphore_flush() with priority inheritance. Close #3235.
* score: Introduce Thread_queue_Lock_contextSebastian Huber2016-09-081-1/+1
| | | | | | Introduce Thread_queue_Lock_context to contain the context necessary for thread queue lock and thread wait lock acquire/release operations to reduce the Thread_Control size.
* score: Rework CORE inherit priority mutexSebastian Huber2016-05-301-1/+1
| | | | | Provide dedicated seize and surrender methods for inherit priority mutexes. This eliminates CORE_mutex_Attributes.
* score: Rework CORE priority ceiling mutexSebastian Huber2016-05-301-0/+1
| | | | | Rework seize and surrender methods to use CORE_ceiling_mutex_Control. This eliminates CORE_mutex_Disciplines.
* score: Add CORE mutex variantsSebastian Huber2016-05-301-0/+6
| | | | | | | | 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.
* score: Simplify CORE mutexSebastian Huber2016-05-301-0/+1
| | | | | Remove superfluous support for simple binary semaphores. With this we can get rid of the CORE_MUTEX_NESTING_BLOCKS variant.
* score: Add semaphore variantsSebastian Huber2016-05-301-0/+25

* score: Add _Thread_queue_Context_set_MP_callout()Sebastian Huber2016-05-301-16/+4
| | | | | | Add _Thread_queue_Context_set_MP_callout() to simplify _Thread_queue_Context_initialize(). This makes it possible to more easily add additional fields to Thread_queue_Context.
* score: Add Status_Control for all APIsSebastian Huber2016-05-261-76/+0
| | | | | | | | | | | Unify the status codes of the Classic and POSIX API to use the new enum Status_Control. This eliminates the Thread_Control::Wait::timeout_code field and the timeout parameter of _Thread_queue_Enqueue_critical() and _MPCI_Send_request_packet(). It gets rid of the status code translation tables and instead uses simple bit operations to get the status for a particular API. This enables translation of status code constants at compile time. Add _Thread_Wait_get_status() to avoid direct access of thread internal data structures.
* score: Move thread queue MP callout to contextSebastian Huber2016-05-251-4/+17
| | | | | | | | Drop the multiprocessing (MP) dependent callout parameter from the thread queue extract, dequeue, flush and unblock methods. Merge this parameter with the lock context into new structure Thread_queue_Context. This helps to gets rid of the conditionally compiled method call helpers.
* Replace *_Get_interrupt_disable() with *_Get()Sebastian Huber2016-05-201-1/+1
| | | | | Uniformly use *_Get() to get an object by identifier with a lock context.
* score: Rename _Objects_Get_local()Sebastian Huber2016-05-201-1/+1
| | | | | | Rename _Objects_Get_local() into _Objects_Get(). Confusions with the previous _Objects_Get() function are avoided since the Objects_Locations parameter is gone.
* rtems: _Semaphore_Get_interrupt_disable()Sebastian Huber2016-05-201-17/+4
| | | | | | Use _Objects_Get_local() for _Semaphore_Get_interrupt_disable() to get rid of the location parameter. Move remote object handling to semaphore MPCI support.
* rtems: Avoid Giant lock for semaphoresSebastian Huber2016-05-021-20/+0
| | | | Update #2555.
* Optional Classic Semaphore initializationSebastian Huber2016-02-031-23/+1
| | | | Update #2408.
* score: _Objects_Get_isr_disable()Sebastian Huber2015-04-211-3/+7
| | | | | | | Use ISR_lock_Context instead of ISR_Level to allow use of ISR locks for low-level locking. Update #2273.

* score: Multiprocessor Resource Sharing ProtocolSebastian Huber2014-05-281-0/+9
| | | | | | | | | | | | | | | | | | | | | | 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.
