* posix: Implement self-contained POSIX mutexSebastian Huber2017-10-051-1/+0
| | | | | | | | POSIX mutexes are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3112.
* posix: Implement self-contained POSIX condvarSebastian Huber2017-10-051-1/+0
| | | | | | | | POSIX condition variables are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3113.
* posix: Implement self-contained POSIX rwlocksSebastian Huber2017-10-051-1/+0
| | | | | | | | POSIX rwlocks are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3115.
* posix: Implement self-contained POSIX barriersSebastian Huber2017-10-051-1/+0

* score: Fix user extensions orderSebastian Huber2017-01-261-2/+2
| | | | | | | | | | | Use forward and reverse order for initial and dynamic extensions. This is the behaviour documented in the C Users Guide. Change thread terminate order to backward to be in line with the thread delete order. Change fatal error order to forward to ensure that initial extensions are called first due the peculiar execution context of fatal error extensions, see _Terminate() documentation. Update #2692.
* 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.
* posix: Add self-contained pthread spinlockSebastian Huber2016-11-231-1/+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.

* Use linker set for system initializationSebastian Huber2015-12-111-0/+75
Make rtems_initialize_data_structures(), rtems_initialize_before_drivers() and rtems_initialize_device_drivers() static. Rename rtems_initialize_start_multitasking() to rtems_initialize_executive() and call the registered system initialization handlers in this function. Add system initialization API available via #include <rtems/sysinit.h>. Update the documentation accordingly. This is no functional change, only the method to call the existing initialization routines changes. Instead of direct function calls a table of function pointers contained in the new RTEMS system initialization linker set is used. This table looks like this (the actual addresses depend on the target). nm *.exe | grep _Linker | sort 0201a2d0 D _Linker_set__Sysinit_begin 0201a2d0 D _Linker_set__Sysinit_bsp_work_area_initialize 0201a2d4 D _Linker_set__Sysinit_bsp_start 0201a2d8 D _Linker_set__Sysinit_rtems_initialize_data_structures 0201a2dc D _Linker_set__Sysinit_bsp_libc_init 0201a2e0 D _Linker_set__Sysinit_rtems_initialize_before_drivers 0201a2e4 D _Linker_set__Sysinit_bsp_predriver_hook 0201a2e8 D _Linker_set__Sysinit_rtems_initialize_device_drivers 0201a2ec D _Linker_set__Sysinit_bsp_postdriver_hook 0201a2f0 D _Linker_set__Sysinit_end Add test sptests/spsysinit01.
