* rtems: Move _Status_Object_name_errors_to_statusSebastian Huber2018-06-053-50/+67
| | | | | | Move _Status_Object_name_errors_to_status to a separate file to avoid a dependency on errno. Dependencies to errno are hard to be removed by the linker garbage collection.
* Use _Thread_Dispatch_direct()Sebastian Huber2018-02-084-5/+5
| | | | | | | Use _Thread_Dispatch_direct() for operations that block the executing thread. This ensures that we get a fatal error (INTERNAL_ERROR_BAD_THREAD_DISPATCH_DISABLE_LEVEL) if we try to block in an invalid context, e.g. during system start or an interrupt handler.
* rtems: Use _Per_CPU_Get_executing()Sebastian Huber2018-02-082-2/+2

* score: Introduce new monotonic clockSebastian Huber2018-02-023-3/+3
| | | | | | | | Rename PER_CPU_WATCHDOG_MONOTONIC to PER_CPU_WATCHDOG_TICKS. Add new PER_CPU_WATCHDOG_MONOTONIC which is based on the system uptime (measured by timecounter). Close #3264.
* score: Rename _Watchdog_Realtime_from_*()Sebastian Huber2018-02-022-2/+2
| | | | | | Rename _Watchdog_Realtime_from_*() to _Watchdog_Ticks_from_*(). Update #3264.
* Remove make preinstallChris Johns2018-01-2551-10815/+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: Fix rtems_task_mode()Sebastian Huber2018-01-191-8/+0
| | | | | | | | | | | A rtems_configuration_is_smp_enabled() inside a !defined( RTEMS_SMP) block makes no sense. Remove !defined( RTEMS_SMP ) conditions. Test tm04 works now again. Update #3000.
* taskmode.c: Ensure all error checking is done before modifying executingJoel Sherrill2017-12-061-3/+31
| | | | | | | Also use single conditional expressions to simplify error checking. Combined, this all resulted in a block of SMP enabled error checking. Updates #3000.
* score: Use self-contained API mutexSebastian Huber2017-12-042-2/+1
| | | | | | | | | | Use a self-contained recursive mutex for API_Mutex_Control. The API mutexes are protected against asynchronous thread cancellation. Add dedicated mutexes for libatomic and TOD. Close #2629. Close #2630.
* score: Simplify global constructionSebastian Huber2017-11-221-20/+4
| | | | Update #3243.
* Fix comments for object lookup error to RTEMS status mapMartin Erik Werner2017-11-211-3/+3
| | | | | | | | | | | | | | | | | | Based on correlation with the enum for object lookup errors in cpukit/score/include/rtems/score/objectimpl.h: typedef enum { OBJECTS_NAME_OR_ID_LOOKUP_SUCCESSFUL, OBJECTS_INVALID_NAME, OBJECTS_INVALID_ADDRESS, OBJECTS_INVALID_ID, OBJECTS_INVALID_NODE } Objects_Name_or_id_lookup_errors; update the comments regarding the object lookup error to status map to match.

* 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: Check thread resource count in timer serverSebastian Huber2017-11-161-1/+7
| | | | | | | The watchdog routines invoked by the timer server may use mutexes for synchronization. Ensure that the resource count of the timer server is zero after each watchdog routine invocation. This helps to detect broken watchdog routines.
* rtems: rtems_clock_get_ticks_per_second()Sebastian Huber2017-10-252-0/+5
| | | | | | | Add macro implementation for rtems_clock_get_ticks_per_second() for C/C++ to avoid the function call overhead. A rtems_clock_get_ticks_per_second() is still provided for language bindings (e.g. Ada).
* score: Move thread queue timeout handlingSebastian Huber2017-10-244-4/+16
| | | | | Update #3117. Update #3182.
* score: Rename _Watchdog_Ticks_from_*()Sebastian Huber2017-10-242-2/+2
| | | | | | | | | | Rename _Watchdog_Ticks_from_*() to _Watchdog_Realtime_from_*(). This highlights that these routines are used for the CLOCK_REALTIME watchdogs (in contrast to CLOCK_MONOTONIC). Update #3117. Update #3182.
* rtems: Simplify RTEMS_MILLISECONDS_TO_MICROSECONDSSebastian Huber2017-10-241-1/+1
| | | | | | | Remove the cast so that it can be used in C pre-processor directives. Update #3117. Update #3182.
* score: Add _Watchdog_Ticks_per_secondSebastian Huber2017-10-241-4/+1
| | | | | | | | This value is frequently used. Avoid the function call overhead and the integer division at run-time. Update #3117. Update #3182.
* score: Add _Thread_Add_timeout_ticks()Sebastian Huber2017-10-242-12/+2
| | | | | | | | Replace _Thread_Timer_insert_monotonic() with _Thread_Add_timeout_ticks(). Update #3117. Update #3182.
* score: Rename _Watchdog_Per_CPU_insert_monotonic()Sebastian Huber2017-10-172-2/+2
| | | | | | | | Rename _Watchdog_Per_CPU_insert_monotonic() in _Watchdog_Per_CPU_insert_ticks(). Update #3117. Update #3182.
* score: Rename watchdog variantsSebastian Huber2017-10-178-10/+10
| | | | | | | | | | | Rename PER_CPU_WATCHDOG_RELATIVE in PER_CPU_WATCHDOG_MONOTONIC to highlight the corresponding POSIX CLOCK_MONOTONIC. Rename PER_CPU_WATCHDOG_ABSOLUTE in PER_CPU_WATCHDOG_REALTIME to highlight the corresponding POSIX CLOCK_REALTIME. Update #3117. Update #3182.

| | | | | Cast the internal PRIORITY_MAXIMUM to the right type for a Classic API task priority to avoid integer conversion warnings.
* score: Add _Thread_queue_Object_nameSebastian Huber2017-01-311-1/+1
| | | | | | | | | | | | | Add the special thread queue name _Thread_queue_Object_name to mark thread queues embedded in an object with identifier. Using the special thread state STATES_THREAD_QUEUE_WITH_IDENTIFIER is not reliable for this purpose since the thread wait information and thread state are protected by different SMP locks in separate critical sections. Remove STATES_THREAD_QUEUE_WITH_IDENTIFIER. Add and use _Thread_queue_Object_initialize(). Update #2858.
* rtems: Fix _Rate_monotonic_Renew_deadline()Kuan-Hsun Chen2017-01-301-4/+7
| | | | | | | | | | | | Prepare a precondition to prevent the potential integer overflow.

* Enhancement of the RMS manager for the overrun handling.Kuan-Hsun Chen2017-01-134-9/+176
| | | | | | | | | | | | | | | Three additional functions: rtems_rate_monotonic_postponed_job_count, _Rate_monotonic_Renew_deadline, and _Rate_monotonic_Release_postponed_job. Four refined functions: _Rate_monotonic_Activate, _Rate_monotonic_Block_while_expired, rtems_rate_monotonic_period, _Rate_monotonic_Timeout. Rate_monotonic_Control contains one counter for counting the postponed jobs and one for recording the recent deadline. Update #2795.
* posix: shared memory supportGedare Bloom2017-01-131-0/+1
| | | | | | | | | Add POSIX shared memory manager (Shm). Includes a hook-based approach for the backing memory storage that defaults to the Workspace, and a test is provided using the heap. A test is also provided for the basic use of mmap'ing a shared memory object. This test currently fails at the mmap stage due to no support for mmap.
