Mwait works as follows: 1. A cpu monitors an address of interest (monitor instruction) 2. A cpu calls mwait - this loads the cache line into that cpu's cache. 3. The cpu goes to sleep. 4. When another processor requests write permission for the line, it is evicted from the sleeping cpu's cache. This eviction is forwarded to the sleeping cpu, which then wakes up.
