Hello I'm taking a class on operating systems and it includes, happily, many Linux examples, outlining OS internal structures and algorithms. I wanted to delve into the Scheduler, particularly the CFS that has been implemented and to try running and testing things such as what is outlined here http://www.embedded.com/design/operating-systems/4371651/Comparing-the-real-... In order to do this, I need to compile and code the Kernel and Kernel modules. I've done this many many time in years gone by, but the current kernel has seemed to have grown even more than I anticipated. For those who work on the kernel and drivers everyday, what would you recommend as a best approach to tinker with the scheduler or even tinker with struct.h entries. I set up a VM with oracles virtualbox, and even that was new to me. I used to keep a usb drive to development and rebooting when I last attempted this. Ruben
