(performance impact).
When such timer is available on an architecture, it should really be
made LTTng's default choice.
And BTW, with such a 32 bits timer, you would need to use my 32-64
bits synthetic TSC (see how asm-mips/ltt.h is implemented).

Mathieu
Thanks!

Instead of passing the cpu id as a marker parameter, why don't you
simply use smp_processor_id() right here ?

high-overhead and people
wont start arguing about trace compatibility either, etc.
I think Frank's response explains things in enough depth.

= stuck on rq_lock :( ).
OK, good to know. Guess we need a call_sched() for -rt and for
preemptible RCU sooner rather than later...
Yup, I would need call_sched() and sched_barrier().
Thanks,
Mathieu
