LCE12 - Peeking into your Linux system: Training - 30 Oct 2012 - BV2
Channel: Linaro On Air
Date: 2012-10-30

Do you know what is going on in your Linux system? Why the CPU wakes up so much? What CPU is your thread running on? Want to see task migration in action?

Vincent Guittot will walk us through various tools available in the kernel to allow us to peek into the activity of the system (user and kernel threads). He uses these to tweak the way the Linux scheduler works. These tools allows us to study a system and optimise it for power and performance.

Some of the tools covered are: ftrace, kernelshark, cyclictest.
