* posix: Remove unused OBJECTS_POSIX_INTERRUPTSSebastian Huber2019-05-201-3/+0

* score: Rename _SMP_Get_processor_count()Sebastian Huber2019-04-112-2/+2
| | | | | | | Rename _SMP_Get_processor_count() in _SMP_Get_processor_maximum() to be in line with the API level rtems_scheduler_get_processor_maximum(). Update #3732.
* rtems: Add rtems_scheduler_get_processor_maximum()Sebastian Huber2019-04-091-2/+2
| | | | | | | | | | | Add rtems_scheduler_get_processor_maximum() as a replacement for rtems_get_processor_count(). The rtems_get_processor_count() is a bit orphaned. Adopt it by the Scheduler Manager. The count is also misleading, since the processor set may have gaps and the actual count of online processors may be less than the value returned by rtems_get_processor_count(). Update #3732.
* rtems: Add rtems_scheduler_get_processor()Sebastian Huber2019-04-091-2/+2
| | | | | | | | | | | Add rtems_scheduler_get_processor() as a replacement for rtems_get_current_processor(). The rtems_get_current_processor() is a bit orphaned. Adopt it by the Scheduler Manager. This is in line with the glibc sched_getcpu() function. Deprecate rtems_get_current_processor(). Update #3731.
* Remove superfluous <rtems/system.h> includesSebastian Huber2019-03-1415-15/+0

* Remove explicit file names from @fileSebastian Huber2019-02-282-2/+2
| | | | | | This makes the @file documentation independent of the actual file name. Update #3707.
* score: Avoid some deadlocks in _Once()Sebastian Huber2019-02-181-2/+3
| | | | | | | | Recursive usage of the same pthread_once_t results now in a deadlock. Previously, an error of EINVAL was returned. This usage scenario is invalid according to the POSIX pthread_once() specification. Close #3334.
* Adjust interrupt mode tests for some CPU portsSebastian Huber2019-01-091-1/+3
| | | | | | | In case the robust thread dispatch is enabled by the CPU port, then the interrupt level must not be changed through the task mode. Update #3000.
* rtems: Allow to set ISR level 0 in SMP configSebastian Huber2019-01-091-0/+1
| | | | Update #3000.
* Separate task mode checksSebastian Huber2019-01-091-15/+15
| | | | Update #3000.
* score: Static Objects_Information initializationSebastian Huber2018-12-1418-490/+466
| | | | | | | | | | | Statically allocate the objects information together with the initial set of objects either via <rtems/confdefs.h>. Provide default object informations with zero objects via librtemscpu.a. This greatly simplifies the workspace size estimate. RTEMS applications which do not use the unlimited objects option are easier to debug since all objects reside now in statically allocated objects of the right types. Close #3621.
* score: Remove Objects_Information::auto_extendSebastian Huber2018-12-141-1/+1
| | | | | | | Use Objects_Information::objects_per_block to provide this information. Add and use _Objects_Is_auto_extend(). Update #3621.
* score: Remove Objects_Information::maximumSebastian Huber2018-12-071-1/+1
| | | | | | | This information is already present in Objects_Information::maximum_id. Add and use _Objects_Get_maximum_index(). Update #3621.
* score: Optimize object lookupSebastian Huber2018-12-073-8/+16
| | | | | | | | | | | | | | | | Use the maximum ID for the ID to object translation. Using the maximum ID gets rid of an additional load from the object information in _Objects_Get(). In addition, object lookups fail for every ID in case the object information is cleared to zero. This makes it a bit more robust during system startup (see new tests in spconfig02). The local table no longer needs a NULL pointer entry at array index zero. Adjust all the object iteration loops accordingly. Remove Objects_Information::minimum_id since it contains only redundant information. Add _Objects_Get_minimum_id() to get the minimum ID. Update #3621.
* score: Remove Objects_Information::is_stringSebastian Huber2018-12-078-16/+8
| | | | | | Use Objects_Information::name_length to store this information. Update #3621.
* rtems: Add rtems_scheduler_get_maximum_priority()Sebastian Huber2018-12-071-0/+53
| | | | Update #3636.
* score: Avoid sbintime_t in API headersSebastian Huber2018-12-072-0/+2
| | | | | | | | | | The sbintime_t is a non-POSIX type and not visible if strict standard options are selected. Move implementation details from <rtems/score/timestamp.h> to <rtems/score/timestampimpl.h>. Update #3598.
* rtems: Fix rtems_task_restart() argument typeSebastian Huber2018-12-061-2/+2

* rtems: Simplify rtems_interrupt_catch()Sebastian Huber2018-11-121-33/+5
| | | | | | Remove casts and superfluous inline functions. Update #3585.
* rtems: Avoid include of <rtems/score/scheduler.h>Sebastian Huber2018-11-121-0/+31
| | | | Update #3598.
* rtems: Avoid <rtems/score/timecounter.h> in APISebastian Huber2018-11-121-0/+31
| | | | | | Use a real function for rtems_clock_get_uptime_seconds(). Update #3598.

| | | | Update #3598.
* rtems: Remove Modes_ControlSebastian Huber2018-11-122-2/+2
| | | | | | | Use rtems_mode directly. This is in line with rtems_attribute and rtems_option. Update #3598.

* score: Fix legacy RTEMS_STATIC_ASSERT()Sebastian Huber2018-10-053-6/+18
| | | | | | | | | In standard C pointer operands are not allowed in integer constant expressions. Avoid a static assertion based on an array typedef since this could lead to warnings ("variably modified 'x' at file scope" and "typedef 'x' locally defined but not used"); This implementation requires unique messages.
* rtems: Add rtems_task_exit()Sebastian Huber2018-10-012-0/+39
| | | | Update #3533.
* score: Add thread pin/unpin supportSebastian Huber2018-09-101-1/+1
| | | | | | | | | Add support to temporarily pin a thread to its current processor. This may be used to access per-processor data structures in critical sections with enabled thread dispatching, e.g. a pinned thread is allowed to block. Update #3508.
* score: Fix _Addresses_Subtract()Sebastian Huber2018-08-102-8/+8
| | | | | | Use architecture-specific integer type for an address difference. Update #3486.
* rtems: Parameter types in rtems_partition_create()Sebastian Huber2018-08-101-2/+2
| | | | | | | | | | Use uintptr_t to specify the length of the partition buffer area instead of uint32_t. This is in line with rtems_region_create(). On 64-bit targets, the length may exceed 4GiB. Use size_t for the buffer size, since on some targets the single object size is less than the overall address range, e.g. m32c sizeof(uintptr_t) > sizeof(size_t). Update #3486.
* rtems: Relax partition buffer area alignmentSebastian Huber2018-08-021-2/+2
| | | | | | | | | | | | | | | The partition buffer area alignment required by rtems_partition_create() was too strict since it was checked via _Addresses_Is_aligned() which uses CPU_ALIGNMENT. The CPU_ALIGNMENT must take long double and vector data type alignment requirements into account. For the partition maintenance only pointer alignment is required (Chain_Node, which consists of two pointers). The user should ensure that its partition buffer area is suitable for the items it wants to manage. The user should not be burdened to provide buffers with the maximum architecture alignment, e.g. why need a 16 byte aligned buffer if you want to manage items with 4 byte integers only? Update #3482.
* score: Remove CPU_PARTITION_ALIGNMENTSebastian Huber2018-08-021-2/+13
| | | | | | | | | | | | | | Use the CPU_SIZEOF_POINTER alignment instead. The internal alignment requirement is defined by the use of Chain_Node (consisting of two pointers) to manage the free chain of partitions. It seems that previously the condition CPU_PARTITION_ALIGNMENT >= sizeof(Chain_Node) was true on all CPU ports. Now, we need an additional check. Update #3482.
* 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.
