Physio is supposed to do this and it does. But my physio cheats. It uses copyin/copyout to move the user data into kernel data space. That's the copy I would like to avoid. I noticed that Sun's physio does not do a copy. But I guess it uses a different mechanism for accessing user space. Tony Cooper sramtrc@albert.dsir.govt.nz
