Re: [RFC PATCH] virtio_ring: Use DMA API if guest memory is encrypted

Hello,

Just going back to this question which I wasn't able to answer.

So far so good, but now a question:

how are we handling guest address width limitations?
Is VIRTIO_F_ACCESS_PLATFORM_IDENTITY_ADDRESS subject to
guest address width limitations?
I am guessing we can make them so ...
This needs to be documented.

I'm not sure. I will get back to you on this.

We don't have address width limitations between host and guest.
