MONITOR/MWAIT problem

[ntjioe29]

Hello,

I am trying to implement MONITOR/MWAIT in Linux user space but I always get Illegal Instructions when I try to run it. Does anyone willing to share their MONITOR/MWAIT implementation?

From my experience they are usually just prohibited in user-space, like CLI/STI.
