Now the minimum interrupt time is 10ms, I want to get a 1ms interrupt, how?
Can I use the way of edit the macro definition in /include/asm/param.h and then recompile the kernel?
change #define HZ 100
to #define HZ 1000
I am not sure whether this way is OK, whether the HW can support this,below is the basic information of my environment:
yellow dog linux 2.4.22-2
