Hi to all,

   I'm wondering whether you guys have tried to use 2 timers. One is for the Linux \
Systick/heartbeat, and one for RTAI.  Just have a couple of things I just want to \
clarify:

1) Is the recover_jiffies being called together with the Linux Systick?

2) When the rt_timer_handler pends TIMER_8254_IRQ, is it essentially pending the \
recover_jiffies?

  I'm trying to use 2 timers on uCSimm (RTC for Linux and the general purpose timer \
for RTAI) and I'm quite unclear about the dependencies. Should I do a "move \
0x2300,%sr" to enable my RTC during cli()? I couldn't go back to the console once I \
load a module that starts the timer. 

Thanks for your time!

Daniel
