* drvmgr: Use API mutexSebastian Huber2017-12-061-10/+1

* score: Use self-contained API mutexSebastian Huber2017-12-042-18/+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.

* sapi: New implementation of rtems_panic()Sebastian Huber2017-11-223-0/+45
| | | | | | | | | | | | The previous rtems_panic() implementation was quite heavy weight. It depended on _exit() which calls the global destructors. It used fprintf(stderr, ...) for output which depends on an initialized console device and the complex fprintf(). Introduce a new fatal source RTEMS_FATAL_SOURCE_PANIC for rtems_panic() and output via vprintk(). Update #3244.
* cpukit: Add _arc4random_getentropy_fail.Christian Mauderer2017-11-171-1/+2
| | | | | | | Add a default implementation of _arc4random_getentropy_fail with an internal error. Update #3239.

| | | | | | | Change "==" to "=", since "==" for comparison is not available in POSIX sh. Signed-off-by: Martin Erik Werner <martinerikwerner@gmail.com>
* cpukit: Add a Version API.Chris Johns2017-11-106-1/+227
| | | | | | | | Provide functions to get the version string, major, minor and revision numbers and the version control identifer that is a unique tag for the version control system. Update #3199.

* confdefs: Warn about problematic ticks per secondSebastian Huber2017-10-241-0/+4
| | | | | | | | A non-integer clock ticks per second value may lead to inaccurate time format conversions. Update #3117. Update #3182.
* score: Add _Watchdog_Ticks_per_secondSebastian Huber2017-10-241-0/+4
| | | | | | | | This value is frequently used. Avoid the function call overhead and the integer division at run-time. Update #3117. Update #3182.

* posix: Implement self-contained POSIX semaphoresSebastian Huber2017-10-051-0/+25
| | | | | | | | | | | | | | For semaphore object pointer and object validation see POSIX_SEMAPHORE_VALIDATE_OBJECT(). Destruction or close of a busy semaphore returns an error status. The object is not flushed. POSIX semaphores are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3116.

| | | | | | Add new fatal error INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNIT. Update #3077.
* score: Make EDF the default SMP schedulerSebastian Huber2017-07-101-2/+2
| | | | | | | | | | | | | The EDF SMP scheduler supports simple thread processor affinities (see #3059) with a small run-time overhead. The current default SMP scheduler lacks support for thread processor affinities at all. The EDF SMP scheduler offers a good feature set for most applications. So, use it by default. Run-time libraries like libgomp, MTAPI, work stealing schedulers, language interpreters (e.g. Erlang virtual machine), maintainence of per-processor data (e.g. Universal Memory Allocator (UMA)), etc. use a one-to-one thread processor affinity for example. Update #3063.

* confdefs.h: Add SMP enabled field to configurationSebastian Huber2017-05-162-1/+12
| | | | | | | | | | | Do not use the processor count to determine if SMP is enabled. Instead use a dedicated configuration option. Enable SMP by default in SMP configurations. Add CONFIGURE_DISABLE_SMP_CONFIGURATION to all test which would fail otherwise. Update #3001.
* confdefs.h: Fix compile error in non-SMP cfgSebastian Huber2017-05-161-1/+1
| | | | | | Bug introduced by f778b7f3f177a39505aeea61206e95fc54f875be. Update #3001.

* confdefs.h: CONFIGURE_DISABLE_SMP_CONFIGURATIONSebastian Huber2017-05-111-2/+6
| | | | | | | | | | | Enable the SMP configuration by default in case SMP is enabled. Add configuration option CONFIGURE_DISABLE_SMP_CONFIGURATION to disable it explicitly. Add CONFIGURE_DISABLE_SMP_CONFIGURATION to all test which would fail otherwise. Update #3001.

| | | | | | | Rename CONFIGURE_SMP_MAXIMUM_PROCESSORS to CONFIGURE_MAXIMUM_PROCESSORS since the SMP part is superfluous. Update #2894.

* posix: shared memory supportGedare Bloom2017-01-131-0/+39
| | | | | | | | | 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.

| | | | | | | | | 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.
