2020-12-02sapi: Canonicalize @defgroup and @file commentsSebastian Huber1-0/+9
Adjust group identifier and names to be in line with a common pattern. Use common phrases for the group and file brief descriptions. Update #3706.
2020-04-16Canonicalize config.h includeSebastian Huber1-1/+1
Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
2019-04-09rtems: Add rtems_scheduler_get_processor_maximum()Sebastian Huber1-1/+1
Add rtems_scheduler_get_processor_maximum() as a replacement for rtems_get_processor_count(). The rtems_get_processor_count() is a bit orphaned. Adopt it by the Scheduler Manager. The count is also misleading, since the processor set may have gaps and the actual count of online processors may be less than the value returned by rtems_get_processor_count(). Update #3732.
2015-06-26score: Simplify <rtems/system.h>Sebastian Huber1-0/+1
Drop the <rtems/score/percpu.h> include since this file exposes a lot of implementation details.
2014-04-11rtems: Rename rtems_smp_get_processor_count()Sebastian Huber1-1/+1
Rename rtems_smp_get_processor_count() in rtems_get_processor_count(). Make rtems_get_processor_count() a function in uni-processor configurations to enable ABI compatibility with SMP configurations.
2014-03-21Change all references of rtems.com to rtems.org.Chris Johns1-1/+1
2014-03-14score: Add SMP lock profiling supportSebastian Huber1-0/+62
2014-03-14score: Add per-CPU profilingSebastian Huber1-0/+61
Add per-CPU profiling stats API. Implement the thread dispatch disable level profiling. The interrupt profiling must be implemented in CPU port specific parts (mostly assembler code). Add a support function _Profiling_Outer_most_interrupt_entry_and_exit() for this purpose.
2014-03-14sapi: Add profiling application level supportSebastian Huber1-5/+8
2014-02-14score: Add CPU counter supportSebastian Huber1-8/+7
Add a CPU counter interface to allow access to a free-running counter. It is useful to measure short time intervals. This can be used for example to enable profiling of critical low-level functions. Add two busy wait functions rtems_counter_delay_ticks() and rtems_counter_delay_nanoseconds() implemented via the CPU counter.
2012-11-27score: Add CPU_Exception_frameSebastian Huber1-4/+4
Add CPU port type CPU_Exception_frame and function _CPU_Exception_frame_print(). The CPU ports of avr, bfin, h8300, lm32, m32c, m32r, m68k, nios2, sh, sparc64, and v850 use an empty default implementation of _CPU_Exception_frame_print(). Add rtems_exception_frame and rtems_exception_frame_print(). Add RTEMS_FATAL_SOURCE_EXCEPTION for CPU exceptions. Use rtems_fatal() with source RTEMS_FATAL_SOURCE_EXCEPTION in CPU ports of i386, powerpc, and sparc for unexpected exceptions. Add third parameter to RTEMS_BSP_CLEANUP_OPTIONS() which controls the BSP_PRINT_EXCEPTION_CONTEXT define used in the default bsp_fatal_extension(). Add test sptests/spfatal26.
2012-08-20libcsupport: Add and use rtems_putc()Sebastian Huber1-5/+3
This reduces code size and provides a function similar to fputc().
2012-03-13Filesystem: New defaults fsync_h and fdatasync_hSebastian Huber1-2/+2
New defaults rtems_filesystem_default_fsync_or_fdatasync() and rtems_filesystem_default_fsync_or_fdatasync_success() for fsync_h and fdatasync_h. The rtems_filesystem_default_fsync_or_fdatasync() sets now errno to EINVAL according to POSIX.
2012-03-13Filesystem: Reference counting for locationsSebastian Huber1-10/+6
o A new data structure rtems_filesystem_global_location_t was introduced to be used for o the mount point location in the mount table entry, o the file system root location in the mount table entry, o the root directory location in the user environment, and o the current directory location in the user environment. During the path evaluation global start locations are obtained to ensure that the current file system instance will be not unmounted in the meantime. o The user environment uses now reference counting and is protected from concurrent access. o The path evaluation process was completely rewritten and simplified. The IMFS, RFS, NFS, and DOSFS use now a generic path evaluation method. Recursive calls in the path evaluation have been replaced with iteration to avoid stack overflows. Only the evaluation of symbolic links is recursive. No dynamic memory allocations and intermediate buffers are used in the high level path evaluation. No global locks are held during the file system instance specific path evaluation process. o Recursive symbolic link evaluation is now limited by RTEMS_FILESYSTEM_SYMLOOP_MAX. Applications can retrieve this value via sysconf(). o The device file system (devFS) uses now no global variables and allocation from the workspace. Node names are allocated from the heap. o The upper layer lseek() performs now some parameter checks. o The upper layer ftruncate() performs now some parameter checks. o unmask() is now restricted to the RWX flags and protected from concurrent access. o The fchmod_h and rmnod_h file system node handlers are now a file system operation. o The unlink_h operation has been removed. All nodes are now destroyed with the rmnod_h operation. o New lock_h, unlock_h, clonenod_h, and are_nodes_equal_h file system operations. o The path evaluation and file system operations are now protected by per file system instance lock and unlock operations. o Fix and test file descriptor duplicate in fcntl(). o New test fstests/fsnofs01.
