[Developer] counting timer tick interrupts, what for?

[Jorge Torres]

Hi everyone,

Please correct me if I'm wrong:

IRQ Time tick interrupts are passed to the  timer_interrupt  function  (for
ia32:  pistachio/arch/ia32/src/timer.cc),  who attends it, and passes it to
the scheduler's handle_timer_interrupt method, right?

Two things I don't understand: what for is the timetick handler keeping a
counter (ticks++)?
is the time tick something I can specify/modify at run time?, how can I
change such ticktime  width?

Oh yes, another thing, I have some free time, and I would like to help on
this elegant irq interrupts handler registration proposed  on OKL4
(irq_manager.register(hwirq, #, FUNCTION)), what is it there to do?

Thank you very much,

Jorge
