I want to work on Linux module programming (Device Drivers). And as a my college project I have to do profiling or benchmarking of a kernel modules based on various parameters. Everywhere I looked, I found info on how to write device drivers, whereas I want info on what parameters affect the performance of any specific driver/module. I also want to know how can I change them to test their various values.
If you are looking for the driver-specific parameters, there's several places you can find information.
And, of course, where things are vague, there's always empirical testing — try it and see.
