User Mode Wait Instructions
The UMONITOR and UMWAIT are user mode (Ring 3) instructions similar to the supervisor mode (Ring 0) MONITOR/MWAIT instructions without the C-state management capability.
TPAUSE us an enhanced PAUSE instruction.
The mnemonics for the three new instructions are:
- UMONITOR: operates just like MONITOR but allowed in all rings.
- UMWAIT: allowed in all rings, and no specification of target C-state.
- TPAUSE: similar to PAUSE but with a software-specified delay. Commonly used in spin loops.
