Hm.  If the GPU memory is really separate from main RAM, which it

That's true, if the user owns the device and the device provides the
memory backing, it doesn't seem like it should count against the user's
locked memory limit.  That'd make things easy for libvirt.  Thanks,

Sounds good.

Is this a QEMU (or even kernel) side change? If so, and we choose to go
through with it, I'll wait for a new spin of this series to see what must
be done in Libvirt to proper support it.


Thanks,
