--- Comment #10 from Gary <gary.c.wang at intel.com> ---
I verified it on Ubuntu 14.10 beta-1 (3.16.0-10-generic #15-Ubuntu) for Intel
CRB with BDW-Y/U CPUs) by "i915_bdw.enable_rc6=0", and cat the value in
/sys/module/i915/parameter/enable_rc6 is 0. if i915_bdw.enable_rc6=1, its value
is also 1.

It seems to work well in drm/i915 driver layer.
