posix-timers: Make them configurable
Some embedded systems have no use for them. This removes about
25KB from the kernel binary size when configured out.
Corresponding syscalls are routed to a stub logging the attempt to
use those syscalls which should be enough of a clue if they were
disabled without proper consideration. They are: timer_create,
timer_gettime: timer_getoverrun, timer_settime, timer_delete,
clock_adjtime, setitimer, getitimer, alarm.
The clock_settime, clock_gettime, clock_getres and clock_nanosleep
syscalls are replaced by simple wrappers compatible with CLOCK_REALTIME,
CLOCK_MONOTONIC and CLOCK_BOOTTIME only which should cover the vast
majority of use cases with very little code.

The IEEE 1588 standard defines a method to precisely
|
|
|
|
synchronize distributed clocks over Ethernet networks. The
|
|
|
|
standard defines a Precision Time Protocol (PTP), which can
|
|
|
|
be used to achieve synchronization within a few dozen
|
|
|
|
microseconds. In addition, with the help of special hardware
|
|
|
|
time stamping units, it can be possible to achieve
|
|
|
|
synchronization to within a few hundred nanoseconds.

also enable at least one clock driver as well.
