Those details still need to be defined, and "an args blob" clearly isn't
that.

Not including the details in the virtio specification is fine, but we
need a *reference* to the details then.

We basically do the same with the execbuffer format.  That is defined by
mesa and virglrenderer instead of being written down as part of the
virtio-gpu spec.

In case you want keep the door open to change the format/content of the
allocator args blob we also need some plan for backward compatibility,
using a capset for example.

cheers,
