This looks quite interesting. Is there anything written up about the
motivations for this design, and how it compares to other similar
mechanisms, say, L4's grant-via-IPC system?
Are the grant references capabilities, or how do you prevent domains
from inventing their own? Who takes care of garbage-collecting them when
a domain exists or dies? Can a domain DoS a Xen-system by allocating all
the grant refs in the system?
best,
Jacob
