The shared buffer pointed by the @gpa also has a format defined in the GHCI
spec. E.g., it has a 'status code' field. Does userspace VMM need to setup
this 'status code' as well?
I recall that we used to set the GET_QUOTE_IN_FLIGHT flag in Qemu but not sure
whether it is still true?
I am thinking if Qemu needs to set it, then we need to expose the structure of
the shared buffer to userspace too.
