Does it exist? You probably want libxl_passthrough_to_string(). Also there's a missing ) to terminate LOGD list of args. I think that's it.

Damn, I'm an idiot. I build tested this on x86. I will find somewhere to build test it on ARM. Thanks for the review. Ian.

I managed to get osstest to let me have one of its arm boxes for long enough to actually build test this and your list of issues was comprehensive. > I think that's it. With those 3 things fixed: > Acked-by: Anthony PERARD <anthony.perard@citrix.com> So, thanks. FTR here is the final version. This now has all the required acks and I will build test it again against staging and push it. Ian.

This is most pleasantly done by also changing the if to a switch.
