[Xen-devel] Usermode with Xen?

[Jun Koi <junkoi2004@xxxxxxxxx>]

Hi,

I found the concept of usermode in Xen is a bit confused. With Linux,
usermode means ring 3 code. In Xen, we also have function like
__copy_from_user(), which does copy data from "usermode" to Xen. But
users of Xen is guest VM, so I think usermode here means  ring 1 (for
paravirtualization) and non-root mode (for VTX/Pacifica). Is that
understanding correct?

Many thanks,
Jun
