* Use right time format in _times()Sebastian Huber2017-10-121-9/+5
| | | | | Update #2740. Close #3179.
* timecounter: Merge FreeBSD change r303382Konstantin Belousov2017-10-121-1/+3
| | | | | | | | | | | | | | | | | | | | | | 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.

* libio: Simplify rtems_libio_iop()Sebastian Huber2017-09-142-8/+14
| | | | | | | 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.
* libio: Remove special-case reference countSebastian Huber2017-09-143-72/+2
| | | | | | The top-level IO library structures should contain no special-case data. Update #2859.
* Simplify and unify BSP_output_charSebastian Huber2017-09-121-2/+2
| | | | | | | | The BSP_output_char should output a char and not mingle with high level processing, e.g. '\n' to '\r\n' translation. Move this translation to rtems_putc(). Remove it from all the BSP_output_char implementations. Close #3122.
* Implement clock()Sebastian Huber2017-09-072-0/+34
| | | | | | | | | | | Newlib uses _times_r() in clock(). The problem is that the _times_r() clock frequency is defined by sysconf(_SC_CLK_TCK). The clock frequency of clock() is the constant CLOCKS_PER_SEC. FreeBSD uses getrusage() for clock(). Since RTEMS has only one process, the implementation can be simplified. Update #3121.
