2017-07-07rtems: Fix rtems_scheduler_remove_processor()Sebastian Huber1-4/+8

2017-03-28rtems: Fix error return pathSebastian Huber1-0/+1
2017-02-02rtems: Fix RTEMS_NO_TIMEOUT defineSebastian Huber1-1/+1
Cast the internal WATCHDOG_NO_TIMEOUT to the right type for a Classic API interval to avoid implict type conversion warnings.
2017-02-01rtems: Fix RTEMS_MAXIMUM_PRIORITY defineSebastian Huber1-1/+1
Cast the internal PRIORITY_MAXIMUM to the right type for a Classic API task priority to avoid integer conversion warnings.
2017-01-31score: Add _Thread_queue_Object_nameSebastian Huber1-1/+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.
2017-01-30rtems: Fix _Rate_monotonic_Renew_deadline()Kuan-Hsun Chen1-4/+7
Prepare a precondition to prevent the potential integer overflow. Remove one redundant parameter in _Rate_monotonic_Renew_deadline(). sptests/sprmsched02: Create A test case for checking the overflow condition of postponed_jobs in rtems_rate_monotonic_period_status. Update #2885.
2017-01-26Remove rtems_rate_monotonic_postponed_job_count()Kuan-Hsun Chen3-34/+6
Add a variable named "count" in rtems_rate_monotonic_period_status structure. Revise rtems_rate_monotonic_get_status() for the postponed job count. sptests/sp69: Add in the verification of the postponed job count for rtems_rate_monotonic_get_status(). Update #2795.
2017-01-24rtems: rtems_rate_monotonic_postponed_job_count()Sebastian Huber1-12/+7
Use proper locking in SMP configurations. Update #2795.
2017-01-24rtems: Fix _Rate_monotonic_Release_postponed_job()Sebastian Huber1-5/+3
Use proper locking in SMP configurations. Update #2795.
2017-01-24rtems: Fix _Rate_monotonic_Renew_deadline()Sebastian Huber3-44/+21
Make _Rate_monotonic_Renew_deadline() static and use proper locking in SMP configurations. Update #2795.
2017-01-13classic: adjust names of RM postponed job functionsGedare Bloom2-9/+14
closes #2795
2017-01-13Enhancement of the RMS manager for the overrun handling.Kuan-Hsun Chen4-9/+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.
2017-01-13posix: shared memory supportGedare Bloom1-0/+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.
2017-01-12rtems: Use header file for rtems_object_get_name()Sebastian Huber1-10/+1
2017-01-12score: Replace STATES_DELAYINGSebastian Huber1-1/+1
Replace STATES_DELAYING with STATES_WAITING_FOR_TIME. There is no need for separate timeout thread states. The Thread_Control::Timer::header and Watchdog_Control::cpu members can be used to figure out the kind of timeout.
2017-01-11Remove obsolete __RTEMS_HAVE_SYS_CPUSET_H__Joel Sherrill4-14/+0
2016-12-12score: Introduce _Internal_error()Sebastian Huber1-8/+2
2016-12-12Add INTERNAL_ERROR_RTEMS_INIT_TASK_CREATE_FAILEDSebastian Huber1-2/+6
Update #2825.
2016-12-09score: Remove fatal is internal indicatorSebastian Huber1-2/+1
The fatal is internal indicator is redundant since the fatal source and error code uniquely identify a fatal error. Keep the fatal user extension is internal parameter for backward compatibility and set it to false always. Update #2825.
2016-12-02rtems: Use _Thread_Dispatch_direct()Sebastian Huber2-2/+2
Update #2797.
2016-12-02rtems: Fix rtems_scheduler_add_processor()Sebastian Huber1-4/+1
Fix thread dispatch profiling of rtems_scheduler_add_processor(). Update #2797.
2016-12-02score: Initialize thread queue context earlySebastian Huber3-1/+3
Initialize thread queue context early preferably outside the critical section. Remove implicit _Thread_queue_Context_initialize() from _Thread_Wait_acquire().
2016-11-24score: Optimize _Thread_queue_Enqueue()Sebastian Huber1-1/+4
Move thread state for _Thread_queue_Enqueue() to the thread queue context. This reduces the parameter count of _Thread_queue_Enqueue() from five to four (ARM for example has only four function parameter registers). Since the thread state is used after several function calls inside _Thread_queue_Enqueue() this parameter was saved on the stack previously.
2016-11-23posix: Add self-contained pthread spinlockSebastian Huber1-1/+0
Turn pthread_spinlock_t into a self-contained object. On uni-processor configurations, interrupts are disabled in the lock/trylock operations and the previous interrupt status is restored in the corresponding unlock operations. On SMP configurations, a ticket lock is a acquired and released in addition. The self-contained pthread_spinlock_t object is defined by Newlib in <sys/_pthreadtypes.h>. typedef struct { struct _Ticket_lock_Control _lock; __uint32_t _interrupt_state; } pthread_spinlock_t; This implementation is simple and efficient. However, this test case of the Linux Test Project would fail due to call of printf() and sleep() during spin lock ownership: https://github.com/linux-test-project/ltp/blob/master/testcases/open_posix_testsuite/conformance/interfaces/pthread_spin_lock/1-2.c There is only limited support for profiling on SMP configurations. Delete CORE spinlock implementation. Update #2674.
2016-11-23score: Rename _Thread_queue_Enqueue_critical()Sebastian Huber1-1/+1
Delete unused _Thread_queue_Enqueue() and rename _Thread_queue_Enqueue_critical() to _Thread_queue_Enqueue().
2016-11-23score: Add thread queue enqueue calloutSebastian Huber3-31/+44
Replace the expected thread dispatch disable level with a thread queue enqueue callout. This enables the use of _Thread_Dispatch_direct() in the thread queue enqueue procedure. This avoids impossible exection paths, e.g. Per_CPU_Control::dispatch_necessary is always true.
2016-11-18rtems: Conditionally define rtems_interrupt_frameSebastian Huber1-1/+6
Update #2808.
2016-11-18score: Add and use _Thread_Dispatch_direct()Sebastian Huber1-1/+1
This function is useful for operations which synchronously block, e.g. self restart, self deletion, yield, sleep. It helps to detect if these operations are called in the wrong context. Since the thread dispatch necessary indicator is not used, this is more robust in some SMP situations. Update #2751.
2016-11-10rtems: Add scheduler processor add/removeSebastian Huber4-4/+318
Update #2797.
2016-11-09score: Simplify _Scheduler_Get_by_id()Sebastian Huber6-12/+10
Avoid dead code in non-SMP configurations. Return scheduler identifier independent of the current processor count of the scheduler via rtems_scheduler_ident(), since this value may change during run-time. Check the processor count in _Scheduler_Set() under scheduler lock protection. Update #2797.
2016-11-09rtems: Fix rtems_task_create() scheduler selectionSebastian Huber1-1/+1
Use the home scheduler of the executing thread for the created thread. This is in line with pthread_create(). Using the current processor may pick up an unexpected scheduler in case of a temporary migration, e.g. due to locking protocols.
2016-11-03score: Introduce thread resource count methodsSebastian Huber1-1/+1
This makes it easier to conditionally enable/disable the thread resource count usage.
2016-11-03rtems: Fix binary semaphore resource countSebastian Huber1-4/+1
Binary semaphores (not simple binary semaphores) maintain the resource count since 8797c76addf22a2f0ffc3717ff977695e35b9b0b. Do this also for initially locked binary semaphores.
2016-11-02score: Introduce Thread_Scheduler_control::homeSebastian Huber3-4/+4
Replace Thread_Scheduler_control::control and Thread_Scheduler_control::own_control with new Thread_Scheduler_control::home. Update #2556.
2016-11-02rtems: Add rtems_task_iterate()Sebastian Huber3-0/+64
Update #2423.
2016-09-27score: Unify CORE mutex seize/surrenderSebastian Huber2-3/+4
Use the Thread_Control::resource_count for the no protocol mutexes. Merge the no protocol and priority inherit CORE mutex seize/surrender operations.
