I am porting the openPOWERLINK stack (Industrial Ethernet protocol
implementation) to RTEMS. Because RTEMS includes the POSIX layer, I
tried to reuse most of the Linux implementation of openPOWERLINK.
When it came to the timers, I discovered some differences of the POSIX
timer behaviour in RTEMS in respect to Linux. I don't know what the
POSIX standard says in that regard.
POSIX is pretty clear in this regard:
http://pubs.opengroup.org/onlinepubs/009695399/functions/timer_create.html
It is a per-process timer, so the current RTEMS implementation is not
conformant with the POSIX requirements. The question is whether this is
a bug or a feature. If we change the behaviour then we may break
existing RTEMS applications. I am in favour of enforcing POSIX strictly.
Can you please open a ticket:
