Hi James, I will be happy to ginea pig your work regarding kexec/kdump, as soon as you got something testable let me know.
I guess the first validation step will be kexec so we can boot the 2nd kernel and have kcore at hand. Good luck with this new challenge :) On the side of this, do you think getting a guest dump from qemu is worth a trail to investigate. (I am iliterate here dunno if this is doable or not) Cheers Phi On Tue, Jun 4, 2013 at 1:05 PM, James King <james.k...@linaro.org> wrote: > Hi Phi, > > As part of my Linaro assignee role, I am working on implementation of > kexec/crashdump for armv8.
