Hi,

 

I've seen a similar message regarding the changing of the HZ value in
the Linux kernel, but there hasn't been a solution on the list. 

 

We wish to increase the HZ value in the Linux kernel from 100 (10ms
period) to 1000 (1 ms period). I've changed the actual value of HZ in
include/asm-arm/param.h, but I don't see any change: timer ticks are
still 10ms. This can be shown by running procinfo -n1 on the DVEVM and
examining IRQ35, which is the System Tick. Its value is increased with
exactly 100 every second...

 

As far as I can tell, the IRQ35 period is calculated in
arch/arm/mach-davinci/time.c as: ((CLOCK_TICK_RATE / HZ) - 1), where
CLOCK_TICK_RATE equals 27MHz (hardware timer).

Who can tell us what we need to do to increase the HZ as used in the
kernel? 

Thanks,

Sander Huijsen
