Len Brown 32e9518005 intel_idle: export both C1 and C1E ... Here we disable HW promotion of C1 to C1E and export both C1 and C1E and distinct C-states. This allows a cpuidle governor to choose a lower latency C-state than C1E when necessary to satisfy performance and QOS constraints -- and still save power versus polling. This also corrects the erroneous latency previously reported for C1E -- it is 10usec, not 1usec. Note that if you use "intel_idle.max_cstate=N", then you must increment N by 1 to get the same behavior after this change. Signed-off-by: Len Brown <len.brown@intel.com>		2013-02-13 18:22:08 -05:00
