Hi All,

I'd like to investigate kernel crashdump debuging for armv8.

For this I need a crashdump, basically I would be happy with a vmlinux with debuginfos (-g compiled) either as 1 a.out or a splitted a.out ( ala suse) a save state of some sort (a crash notes records) and a vmcore that could be a simple raw file, a core file, an elf file, a kdump format.

I am not to picky on the crashdump format for the time being.

What would be my best bet?

- Does someone as a crashdump at hand, I would simply download the vmlinux/vmcore/crashnotes.

- Make it myself as a qemu guest crash.

If qemu is able to produce a guest core dump, I could build a kernel -g then trig a guest dump (if someone did this  any receipe would be appreciated :) )

- Make it myself with a manual kdump (ideal) or kexec phases.

I would then have to install linaro, get the source, build the -g vmlinux, then try some kexec sequence and catch the kcore, or better if available I could do a makedumpfile to get a kdump.

Again if one did this, any help appreciated.

Cheers,
Phi
