20:33 <leitao> fche, if I want to add support for vector registers on ppc64le on SystemTap, what is your recommendation? Start with register() or print_regs()? Looking at register, it seems it only grab registers from ptrace pt_regs struct.

21:17 <fche> leitao, would have to see how exactly kernel code can get at vector registers - at all. maybe inline assembly code with direct %xmmwhatever?

21:17 <fche> dunno, would start with hand-made c code

21:43 <gromero> fche: Hi. How do you usually debug a probe that crashes the kernel? Given it's on a VM? Any hint on that?

21:56 <drsmith> gromero: Basically you want to be able to watch the console output. For a vm, that might mean using your VM manager instead of ssh'ing into the VM. Another solution would be to use a network console (google 'netconsole").

21:58 <gromero> drsmith: hum, right. so basically you use the kernel backtraces?

21:58 <drsmith> right

21:59 <gromero> ok, thanks!

22:00 <drsmith> good lunk

22:00 <drsmith> or luck even
