Hi Chris, My understanding is that running at efficient freq (RPe) where RPe is greater than the min freq (RPn) (RPe > RPn), at same Vmin voltage should give us better performance right?. Please correct me if my understand is not right Thanks Deepak -----Original Message----- From: Chris Wilson [mailto:chris@xxxxxxxxxxxxxxxxxx] Sent: Sunday, December 8, 2013 9:37 PM To: S, Deepak Cc: intel-gfx@xxxxxxxxxxxxxxxxxxxxx Subject: Re: [PATCH 2/4] drm/i915: set min delay to rpe delay (Efficient frequency) for better performace.

Your perf arguments are fallacious. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
