Neither. I'm looking at the current state of GRUB, not of Xen. Neither of those Xen projects mentions GRUB at all. > The former has been deprecated, the latter is very much active and > apparently usable.

I can tell you that such support is nonexistent, not merely preliminary (aside from the ability to boot a hypervisor, as I mentioned; but that's not what grub-xen-host is about). > I would expect grub-xen-host to be minimally different between ARM and > x86. Much of the support for running in PV mode on x86-based Xen is of course written as relatively generic C code that ought to be usable on other architectures, but there are essential pieces (at minimum: startup code, the hypercall ABI, a relocator, and the build system) that nobody has yet implemented for Xen on ARM, or if they have then I haven't seen it and the work doesn't seem to have gone upstream. I'm sure it would be welcomed, but it wouldn't be entirely trivial. -- Colin Watson [cjwat...@debian.org]
