2018-12-07score: Remove Objects_Information::is_stringSebastian Huber1-2/+1
Use Objects_Information::name_length to store this information. Update #3621.
2018-12-03Convert CPU counter ticks to/from sbintime_tSebastian Huber1-2/+20
The sbintime_t is an efficient time format. Add the ability to convert CPU counter ticks to/from sbintime_t.
2018-10-09build: Move sapi/Makefile.amSebastian Huber3-109/+0
2018-10-04Rename files to make them unique within cpukitSebastian Huber2-1/+1
This allows to build librtemscpu.a in one rush in the future.
2018-06-15Add _CPU_Counter_frequency()Sebastian Huber1-3/+15
Add rtems_counter_frequency() API function. Use it to initialize the counter value converter via the new system initialization step (RTEMS_SYSINIT_CPU_COUNTER). This decouples the counter implementation and the counter converter. It avoids an unnecessary pull in of the 64-bit integer division from libgcc. Update #3456.
2018-06-05Add RTEMS_FATAL_SOURCE_INVALID_HEAP_FREESebastian Huber1-1/+2
An invalid heap usage such as a double free is usually a fatal error since this indicates a use after free. Replace the use of printk() in free() with a fatal error. Update #3437.
2018-06-05Update rtems_fatal_source_text()Sebastian Huber1-2/+3
Add RTEMS_FATAL_SOURCE_PANIC to rtems_fatal_source_text(). Update #3244.
2018-04-04build: Remove EXTRA_DISTSebastian Huber1-1/+0
A "make dist" is not supported. So, it makes no sense to have pure "make dist" related stuff in the Makefile.am.
2018-01-25Remove make preinstallChris Johns22-8315/+0
A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.

2017-12-04score: Use self-contained API mutexSebastian Huber2-18/+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.

2017-11-22sapi: New implementation of rtems_panic()Sebastian Huber3-0/+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.
2017-11-17cpukit: Add _arc4random_getentropy_fail.Christian Mauderer1-1/+2

2017-10-05posix: Implement self-contained POSIX semaphoresSebastian Huber1-0/+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.

Add new fatal error INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNIT. Update #3077.
2017-07-10score: Make EDF the default SMP schedulerSebastian Huber1-2/+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.

Update #3056.
2017-05-16confdefs.h: Add SMP enabled field to configurationSebastian Huber2-1/+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.

Update #3001.
2017-05-11confdefs.h: CONFIGURE_DISABLE_SMP_CONFIGURATIONSebastian Huber1-2/+6

2017-01-13posix: shared memory supportGedare Bloom1-0/+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.
