* posix: Provide shared memory objects by defaultSebastian Huber2018-10-291-1/+1
| | | | Update #2514.
* posix: Provide named semaphores by defaultSebastian Huber2018-10-291-4/+4
| | | | Update #2514.
* score: Remove bogus thread object name supportSebastian Huber2018-10-291-3/+1
| | | | Update #2514.
* 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 Huber2018-10-011-0/+38
| | | | 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 Huber2018-06-052-50/+66
| | | | | | 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.
* 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.

* 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 Huber2017-10-251-0/+2
| | | | | | | 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.
* 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.
* score: Remove CPU_set_ControlSebastian Huber2017-10-113-3/+0
| | | | | | Use Processor_mask instead. Update #2514.
* score: Add _Thread_queue_Dispatch_disable()Sebastian Huber2017-10-104-13/+4

* score: Use struct timespec for TODSebastian Huber2017-10-091-8/+5
| | | | | | | Use the timestamps only for uptime based values. Use struct timespec for the absolute time values (TOD). Update #2740.

| | | | | | | | POSIX condition variables are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3113.

| | | | | | | | Account for the thread processor affinity and make sure that it is possible to allocate a processor to each thread dedicated to a scheduler instance. Update #3059.
* score: Add processor set to scheduler contextSebastian Huber2017-07-073-9/+11
| | | | | | | Replace the simple processor count with the processor set owned by the scheduler instance. Update #3059.

* 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

Update #2885.
