BDW-X idle workaround: force enable MWAIT for internal debug only BDW-X does not currently enable MWAIT, does not export any ACPI C-states, and so it runs in C0 all the time (doesn't even have C1). This hack patch forces MWAIT to be enabled and thus allows intel_idle to load. This patch has been tested to allow 99% PC6 residency, vs 0% out of box. Signed-off-by: Len Brown <len.brown@intel.com>
