Hi, Is there any other way to do this? If I need to write a kernel module that needs to get cpu utilization should I still use proc/stat ? Is there a kernel function that can be used in a module ?
To get the information that's shown in /proc/stat, I'd suggest having a look at fs/proc/stat.c in the kernel tree. HTH, Jonathan Neusch?fer
