Madhu,
I tried this - However the tree would not compile since the
../ti-davinci/arch/arm/mach-davinci/time.c uses the arch_cycle_to_nsec which is
a part of the hrtimers.
unsigned long davinci_gettimeoffset(void)
{
unsigned long now, elapsed, nsec;
now = davinci_timer32_read(davinci_timers[tid_freerun]);
elapsed = now - davinci_timer32_last;
nsec = arch_cycle_to_nsec(elapsed);
return nsec / 1000;
}
I'm not sure why hrtimers are made configurable then - this is specific to
davinci/mv tree it seems!
Please provide me any other pointer in this regard.
Best Regards,
Deepak Shankar V

Subject: Re: Aieee Killing Interrupt handler after 2 days.
Hello Deepak,
From the log, I could see some problem or conflict between the hrtimer and
pm. One way is you can try disabling hrtimer and check.

Madhu
