The qemu model should be fully independent of the underlying HW, it
should not override from HW.
It should check if the underlying supports the model and fail if it
doesn't.

My feeling is that it is undesirable to have the shadowing code in the
VMM at all, as it increases the attack surface/complexity/etc.
There should be a way to fully inhibit legacy mode, and if that means
old kernels don't work that's just how it is.
Jason

The SMMUv3 spec started out with definitions for S1 and S2 as well as
capability bits for them at day 0. So it never had this backward
compatible problem where we want to remove something that was
a mandatory part of the specification.
