* score: Add _IO_Printf() and _IO_Vprintf()Sebastian Huber2017-11-061-0/+46
| | | | | | | | | | | | | | The previous vprintk() implementation had a questionable licence header, lacks support for the 'z' and 'j' format specifiers, is not robust against invalid format specifiers, uses a global variable for output. Replace it with a stripped down version of the FreeBSD kernel kvprintf() function. The new implementation allows a low overhead rtems_snprintf() if necessary. Update #3199. Close #3216.
* posix: Use far future for very long timeoutsSebastian Huber2017-11-021-0/+30
| | | | Close #3205.
* score: Simplify SMP get lowest scheduledSebastian Huber2017-10-281-7/+4
| | | | | | There is no need to pass in the order relation since the scheduled threads reside on an already ordered chain. The caller will decide what to do with the lowest scheduled thread.

| | | | | | | | | Rename _Thread_queue_Context_set_do_nothing_enqueue_callout() into _Thread_queue_Context_set_enqueue_do_nothing_extra(). More _Thread_queue_Context_set_enqueue_*() functions will follow. Update #3117. Update #3182.

* score: Rename _Watchdog_Ticks_from_*()Sebastian Huber2017-10-241-3/+3
| | | | | | | | | | Rename _Watchdog_Ticks_from_*() to _Watchdog_Realtime_from_*(). This highlights that these routines are used for the CLOCK_REALTIME watchdogs (in contrast to CLOCK_MONOTONIC). Update #3117. Update #3182.
* score: Add _Watchdog_Ticks_per_secondSebastian Huber2017-10-241-0/+8
| | | | | | | | This value is frequently used. Avoid the function call overhead and the integer division at run-time. Update #3117. Update #3182.
* score: Add _Thread_Add_timeout_ticks()Sebastian Huber2017-10-241-6/+5
| | | | | | | | Replace _Thread_Timer_insert_monotonic() with _Thread_Add_timeout_ticks(). Update #3117. Update #3182.

| | | | | | | | Rename _Watchdog_Per_CPU_insert_monotonic() in _Watchdog_Per_CPU_insert_ticks(). Update #3117. Update #3182.
* score: Rename watchdog variantsSebastian Huber2017-10-173-26/+30
| | | | | | | | | | | Rename PER_CPU_WATCHDOG_RELATIVE in PER_CPU_WATCHDOG_MONOTONIC to highlight the corresponding POSIX CLOCK_MONOTONIC. Rename PER_CPU_WATCHDOG_ABSOLUTE in PER_CPU_WATCHDOG_REALTIME to highlight the corresponding POSIX CLOCK_REALTIME. Update #3117. Update #3182.

* timecounter: Merge FreeBSD change r303382Konstantin Belousov2017-10-121-7/+14
| | | | | | | | | | | | | | | | | | | | | | Hide the boottime and bootimebin globals, provide the getboottime(9) and getboottimebin(9) KPI. Change consumers of boottime to use the KPI. The variables were renamed to avoid shadowing issues with local variables of the same name. Issue is that boottime* should be adjusted from tc_windup(), which requires them to be members of the timehands structure. As a preparation, this commit only introduces the interface. Some uses of boottime were found doubtful, e.g. NLM uses boottime to identify the system boot instance. Arguably the identity should not change on the leap second adjustment, but the commit is about the timekeeping code and the consumers were kept bug-to-bug compatible.

* score: Remove CPU_set_ControlSebastian Huber2017-10-115-196/+3

* score: Change Timestamp_Control to sbintime_tSebastian Huber2017-10-093-34/+24
| | | | | | | | The timestamp are based on the uptime. There is no need for a 64-bit seconds part. The signed 32-bit seconds part of the sbintime_t limits the uptime to roughly 68 years. Close #2740.
* score: Use struct timespec for TODSebastian Huber2017-10-091-46/+8
| | | | | | | Use the timestamps only for uptime based values. Use struct timespec for the absolute time values (TOD). Update #2740.

| | | | | | | | | | | | | | 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.
* posix: Optimize pthread_once_tSebastian Huber2017-10-051-1/+1
| | | | | | Reduce size of pthread_once_t and make it zero-initialized. Update #3142.
* score: Make status codes unconditionalSebastian Huber2017-10-051-9/+2
| | | | | | | | The internal status codes encode a Classic rtems_status_code and error codes used by the POSIX and C11/C++11 APIs. In case the POSIX API is disabled, the C11/C++11 support must still work. Close #3167.
* score: Simplify red-black tree debug supportSebastian Huber2017-09-271-8/+0
