Hi,

I want to increase CONFIG_HZ value to 1000. Now by default it is 200. So i
can have better time in my module as well as user space.

Is it possbile on mini2440  to achieve 1ms timer by enabling this option
into kernel ???

flylinux,

It is possible to change the CONFIG_HZ variable, but not in the .config
file in the kernel.

you have to change the HZ variable in the
(output/build/)linux-kernel/arch/arm/Kconfig file. The .config file will be
adjusted automaticly. (I only tested this in buildroot)

good luck

Hi,
When I change CONFIG_HZ from 200 to 1000, touch screen does not
work. But, USB mouse is ok. 
Can anyone here help with my problem?
