i'm going to leech off of the collective intelligence of this list
for a few minutes. toward the end of a 1-day kernel course i'm
designing, i want to *very* briefly present some kernel debugging
techniques. given the limited time i'm going to have, i can't see
having more than about 20 or 30 minutes for this, so i can't possibly
get into fancy debugging, such as with kgdb, or anything that requires
a kernel config and reboot. so that doesn't leave me a lot of
options.
i figure the best i can do is talk about SysRq, a number of the
kernel config options that people *could* turn on (under "Kernel
Hacking"), and possibly mounting the debugfs to get access to any
portions of the kernel that bothered to use it. beyond that, i'm
not sure what else could be crammed in there but i'm open to
suggestions. thanks.
