This is not the way I would like to see it. I have some ideas on how this could be implemented, both on the firmware and on the OS side, but let's take that off line. However, as a general note, we need to address this on the spec side, i.e., how to support a platform whose only non-variable storage is behind a controller that is shared with the OS at runtime. @Haojian: for now, there is no point in continuing this discussion on edk2-devel.
