Funnily enough, this is how this is done on intel+linux: `echo 0 > /sys/devices/system/cpu/intel_pstate/no_turbo`

  For just a second there I thought Intel provides the kernel some kind of backwards compatibility mode to clock down to 4.77MHz like the original turbo button.

    There is a pin PROCHOT on all Intel processors that can be used to drop the CPU (and IGP, if equipped) into its lowest-power but still running state. It's designed to allow external voltage regulators on the board to assert that they are overloaded, but I don't see why you couldn't also wire in a turbo button there :=)

      On my Lenovo Yoga it's always on when waking from sleep. You have to connect charger, even for a short time, to drop out of PROCHOT.
