* Remove make preinstallChris Johns2018-01-2520-8191/+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.

| | | | | | | | | | 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 Huber2017-11-221-0/+12
| | | | | | | | | | | | 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 a Version API.Chris Johns2017-11-101-0/+77

* 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.

* 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.

* score: Remove fatal is internal indicatorSebastian Huber2016-12-091-7/+10
| | | | | | | | | 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.
* posix: Add self-contained pthread spinlockSebastian Huber2016-11-231-28/+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.
* score: Rename _Scheduler_AssignmentsSebastian Huber2016-11-091-3/+3
| | | | | | | | Rename _Scheduler_Assignments into _Scheduler_Initial_assignments to make it clear that they may not reflect the run-time scheduler assignment. Update #2797.

* confdefs.h: Do not hide network file systemsSebastian Huber2016-06-091-34/+30
| | | | | Do not hide network file systems if RTEMS_NETWORKING is not defined, since they may be provided by the LibBSD.
* confdefs.h: Fix heap alloc size estimateSebastian Huber2016-05-251-4/+8
| | | | Account for the heap minimum block size.
* cpukit, testsuite: Add rtems_printf and rtems_printer support.Chris Johns2016-05-251-17/+4
| | | | | | | | | | | | | | | | | | | This change adds rtems_printf and related functions and wraps the RTEMS print plugin support into a user API. All references to the plugin are removed and replaced with the rtems_printer interface. Printk and related functions are made to return a valid number of characters formatted and output. The function attribute to check printf functions has been added to rtems_printf and printk. No changes to remove warrnings are part of this patch set. The testsuite has been moved over to the rtems_printer. The testsuite has a mix of rtems_printer access and direct print control via the tmacros.h header file. The support for begink/endk has been removed as it served no purpose and only confused the code base. The testsuite has not been refactored to use rtems_printf. This is future work.
