2018-01-25Remove make preinstallChris Johns10-4589/+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.
2017-12-06libio: Use API mutexSebastian Huber1-17/+2
2017-11-22sapi: New implementation of rtems_panic()Sebastian Huber1-9/+1
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.
2017-11-15libio: Add assert to rtems_libio_iop_drop()Sebastian Huber1-0/+23

2017-09-15libio: Add hold/drop iop referenceSebastian Huber2-26/+57

This simplifies error handling later. Update #3132.
2017-09-14libio: Simplify rtems_libio_iop()Sebastian Huber1-7/+13
Remove the file descriptor validation. This is the job of rtems_libio_check_fd(). Use an inline function instread of a macro. Update #3132.

Close #3134.
2017-09-14libio: Remove special-case reference countSebastian Huber2-42/+0
The top-level IO library structures should contain no special-case data. Update #2859.

2017-06-07Move RTEMS-specific Termios API contentSebastian Huber1-0/+9
Remove obsolete support for OFILL, OFDEL, NLDLY, CRDLY, BSDLY, VTDLY, and FFDLY which is not present on FreeBSD and not implemented in Linux. Update #2833.

Update #2859.
2017-04-03bsps: Fix baud settingsSebastian Huber1-4/+2
Update #2897.

Adding modified FreeBSD headers to synchronize RTEMS termios with FreeBSD. Modify termios to support dedicated input and output baud for termios structure. Updated BSPs to use dedicated input and output baud in termios structure. Updated tools to use dedicated input and output baud in termios structure. Updated termios testsuites to use dedicated input and output baud in termios structure. Close #2897.
2017-03-16libio: Fix deadlock in location managementSebastian Huber1-1/+4
Perform a context-dependent deferred location release to avoid a deadlock on the file system instance locks, for example during a chdir(). Update #2936.
2017-02-28termios: Change tty_rcvwakeup to boolSebastian Huber1-1/+1
Optimize callout invocation check.
2017-02-23termios: Add kqueue() and poll() supportSebastian Huber1-0/+20
Real implementation is provided by libbsd.
2017-02-03termios: Fix static device initalizationSebastian Huber1-1/+17
This enables early printk() support. Update #2838.

2017-01-12Add rtems_assoc_32_to_string()Sebastian Huber1-1/+32
2016-12-16termios: Add TERMIOS_IRQ_SERVER_DRIVENAlexander Krutwig1-4/+6
Add a new interrupt server driven Termios mode (TERMIOS_IRQ_DRIVEN). This mode is identical to the interrupt driven mode except that a mutex is used for device level locking. The intended use case for this mode are device drivers that use the interrupt server, e.g. SPI or I2C connected devices. Update #2839.
2016-12-16termios: Use mutex for task driven modeSebastian Huber1-5/+21
Termios has a task driven mode (TERMIOS_TASK_DRIVEN). This mode aims to avoid long sections with disabled interrupts. This is only partly implemented since the device level state is still protected by disabled interrupts. Use a mutex to protect the device level state in task driven mode to fix this issue. Update #2838.
2016-11-23posix: Add self-contained pthread spinlockSebastian Huber1-1/+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.
2016-09-19termios: Add IO control handlerSebastian Huber1-0/+15
Update #2785.
2016-09-19termios: Use IMFS nodes for new Termios devicesSebastian Huber1-52/+4
This makes the new Termios devices independent of device major/minor numbers. It enables BSP independent Termios device drivers which may reside in the cpukit domain. These drivers require an IMFS and do not work with the device file system. However, the device file system should go away in the future.
2016-05-02posix: Simplify message queuesSebastian Huber1-1/+0
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.
2016-03-30Move various driver interface definition headers file libcsupport/ to include/Joel Sherrill2-239/+0
These were in libcsupport for historical reasons and the placement no longer made sense. As part of this move, some of the files were placed under subdirectories which reflect their installed location. Thank you git for allowing us to move files. Years of CVS resulted in files being somewhere they no longer belonged.
2016-02-03Use linker set for libio initializationSebastian Huber1-15/+0
Update #2408.
2016-02-03Use atexit() handler to close std file descriptorsSebastian Huber1-2/+0

Update #2408.
2016-02-02Filesystem: Export most generic path eval functionSebastian Huber1-0/+1
Add path length parameter to rtems_filesystem_eval_path_start_with_root_and_current() so that users may pass paths without a '\0' termination. Update #2558.
