Carpet. Swept. Under. commit 0d55babc8392754352f1058866dd4182ae587d11 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Aug 2 11:06:28 2018 +0100 drm/i915: Drop stray clearing of rps->last_adj We used to reset last_adj to 0 on crossing a power domain boundary, to slow down our rate of change. However, commit 60548c554be2 ("drm/i915: Interactive RPS mode") accidentally caused it to be reset on every frequency update, nerfing the fast response granted by the slow start algorithm.
