2020-04-16Canonicalize config.h includeSebastian Huber
Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
2018-10-29posix: Provide threads by defaultSebastian Huber
Update #2514.
2017-10-05posix: Implement self-contained POSIX mutexSebastian Huber

2017-10-05posix: Implement self-contained POSIX condvarSebastian Huber

2017-10-05posix: Implement self-contained POSIX barriersSebastian Huber

2017-09-15libio: Use FIFO for iop free listSebastian Huber
Update #3136.
2016-11-23posix: Add self-contained pthread spinlockSebastian Huber
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.
2016-11-04Size optimization for resource snapshotsSebastian Huber
Do not reference the objects information directly.
2016-05-02posix: Simplify message queuesSebastian Huber
The mq_open() function returns a descriptor to a POSIX message queue object identified by a name. This is similar to sem_open(). In contrast to the POSIX semaphore the POSIX message queues use a separate object for the descriptor. This extra object is superfluous, since the object identifier can be used directly for this purpose, just like for the semaphores. Update #2702. Update #2555.
2016-04-21score: Simplify _Objects_Get_next()Sebastian Huber
Remove unused location parameter.
2016-03-18posix: Use per-thread lookup tree for POSIX KeysSebastian Huber
Yields higher performance on SMP systems. Close #2625.
2015-08-31rbheap: Drop direction from _RBTree_Iterate()Sebastian Huber
2015-07-23score: Introduce Thread_queue_HeadsSebastian Huber
Move the storage for the thread queue heads to the threads. Each thread provides a set of thread queue heads allocated from a dedicated memory pool. In case a thread blocks on a queue, then it lends its heads to the queue. In case the thread unblocks, then it takes a free set of threads from the queue. Since a thread can block on at most one queue this works. This mechanism is used in FreeBSD. The motivation for this change is to reduce the memory demands of the synchronization objects. On a 32-bit uni-processor configuration the Thread_queue_Control size is now 8 bytes, compared to 64 bytes in RTEMS 4.10 (other changes reduced the size as well).
2014-12-12Add POSIX key value pairs to resource snapshotSebastian Huber
2014-11-28score: Return heap stats via _Heap_Get_informationSebastian Huber
Print out heap statistics via the MALLOC and WKSPACE shell commands.
2014-03-31score: PR2152: Use allocator mutex for objectsSebastian Huber
Use allocator mutex for objects allocate/free. This prevents that the thread dispatch latency depends on the workspace/heap fragmentation.
2014-03-31score: Thread life cycle re-implementationSebastian Huber
The thread deletion is now supported on SMP. This change fixes the following PRs: PR1814: SMP race condition between stack free and dispatch PR2035: psxcancel reveals NULL pointer access in _Thread_queue_Extract() The POSIX cleanup handler are now called in the right context (should be called in the context of the terminating thread). http://pubs.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_09.html Add a user extension the reflects a thread termination event. This is used to reclaim the Newlib reentrancy structure (may use file operations), the POSIX cleanup handlers and the POSIX key destructors.
