Hi all,
hw.cpu_mwait_{idle,spin} sysctls are now read-only on x86_64.
machdep.mwait.CX.idle and machdep.mwait.CX.spin should be used instead.
The possible values for the above two sysctls are listed in the output
of sysctl machdep.mwait.CX.supported. For machdep.mwait.CX.idle,
"AUTO" and "AUTODEEP" may also be configured.
Best Regards,
sephe
