i'm getting ready to teach a basic device drivers course in a couple weeks with someone else's courseware and i just wanted to bring some sections up to date. there's one section on basic debugging that covers printk() as well as other topics from LDD3 such as printk_ratelimit(), setting the console loglevel and so on.
however, there's obviously more these days -- the "pr_"-prefixed wrappers, dev_dbg() and so on. is there a single source that covers the standard debugging routines in the kernel these days? if not, no big deal, i'll just summarize what i know of.
Don't forget the dynamic printk stuff, that's very powerful stuff that people tend to forget about. good luck, greg k-h
