[Minios-devel] [UNIKRAFT] Xen PVH platform

[Marek Marczykowski-Górecki <marmarek@xxxxxxxxxxxxxxxxxxxxxx>]

Hi,

In Unikraft, some of the Xen platform code is under CONFIG_PARAVIRT, as an
alternative to (incomplete, broken) PVH/HVM support. Would it make sense
to support a build for both PV and PVH at the same time? Technically it
would be possible, since those use different entry points and also
start_info structure has a different magic. But on the other hand,
supporting such configuration would mean slightly bigger binary. And
possibly slight slower (not really sure about that yet).
It looks like the x86/entry64.S and x86/mm.c are the most tricky parts,
but it shouldn't be that hard to support runtime PV/PVH detection.
