Re: How to get cpu utilization through code with least overhead?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 ?
 
Thanks
