<pre>Recant this: But I cannot get RC6 GFX power savings with CONFIG_DRM_I915_GVT=y
enabled.
With .config using this:
CONFIG_DRM_I915_GVT=y
# CONFIG_DRM_I915_GVT_KVMGT is not set
I get:
PkgTmp GFX%rc6 GFXMHz Pkg%pc2 Pkg%pc3 Pkg%pc6 Pkg%pc7 PkgWatt CorWatt GFXWatt
52 99.73 200 2.88 0.44 92.09 0.00 0.32 0.01 0.00
So, mearly enabing just the GVT part which won't load anyway
[ 13.376558] [drm:intel_gvt_init [i915]] Unsupported device. GVT-g is
disabled
Does not impact i915.ko power savings</pre>
