AW: Kernelnewbies Digest, Vol 73, Issue 3

[Warlich, Christof]

Hi John,

what about this tutorial:

https://www.kernel.org/doc/htmldocs/kgdb/

It's the first hit when you google for kdgb, and it got me started.

If you really look for professional tools, the Lauterbach debuggers are really doing a good job and are comparably cheap. But you may only need such tools when your kernel is not yet up and running (i.e. for BSP development) or when you need tracing support beyond the excellent tracing capabilities already provided by the kernel's ftrace infrastructure.

Hope this helps,

Chris

Hi Andrey,

Can you help post some good/still relevant links? Call me stupid, I did google, found a few websites, and most of them are kind of out of contexts(don't know how to follow). For beginners, step-by-step tutorials are the best. so far, sounds like kgdb is promising, but it requires a lot of backgrounds to start with. I still have not figured out the exact steps.

Thank you,

You'd better budget some time to google a bit and watch conference
videos showing debugging techniques :) There are fine videos from past
Kernel Recipes conferences.
