Actually, we use bit map to indicate different power features, and use bit one by one on that feature_mask. PP_DCEFCLK_DPM_MASK = 1 << 13 PP_OVERDRIVE_MASK = 1 << 14 And in another patch, I add gfxoff feature mask below: PP_GFXOFF_MASK = 0x8000 = 1 << 15 So I suggest you can set PP_ACG_MASK = 0x10000 = 1 << 16 here.
