Hi, list

There are several host timers that could be seen through the virtual
file named as /proc/xenomai/timer/coreclk,i.e:

~ # cat /proc/xenomai/timer/coreclk
CPU  SCHED/SHOT       TIMEOUT     INTERVAL    NAME
0    239162/150321         3ms467us    -           [host-timer/0]
1    33839/31631            10ms657us   -           [host-timer/1]
2    22189/19355            60us        -                 [host-timer/2]
3    45244/41172            90us        -                 [host-timer/3]
