Run privileged code with the driver aid

Hello there.

My aim is to communicate with a driver that would create a segment memory with a specified protection level, so my user-level application can copy some protected code there and execute it in that protection level. In x86 this is possible with the aid of a callgate.

Can it be done in x64 ? If one has resources on this, please post.

Best Regards.
