Back in the 2.2.13 kernel days, I would hook up 2 computers via serial ports and could use ddd/gdb to walk through the kernel on the 2nd computer.
My old notes tells me I would enabled "Kernel Hacking -> Kernel support for GDB" when running "make menuconfig", and then add "gdb gdbttyS=1 gdbbaud=115200" when booting the 2nd computer.
Is this still the way to do it?
I'd like to play around with this again after many years of not having looked at the kernel internals. One of the things I found tonight while searching for info on the web is this:
http://kgdb.linsyssoft.com
Is this what it has evolved into, or is this something else? It looks like a commercial product, which is why I was reluctant to dig further into it. I guess what I'm asking is: What is the most common method people use to walk a debugger through the linux kernel?
Thanks,
