2010-02-17 Thread Andrew Brampton
After reading though the kernel source I realise what I want isn't implemented at the moment but I wanted to discuss if this feature would be an useful addition. Basically I want to see counts of how many interrupts for a particular interrupt have fired on each core. Linux has provided this kind
