From d2a08e46215ccb0e8d7ea5011ff07abc43d79860 Mon Sep 17 00:00:00 2001 From: Evan Quan Date: Thu, 14 Nov 2019 16:58:31 +0800 Subject: drm/amd/powerplay: correct fine grained dpm force level setting For fine grained dpm, there is only two levels supported. However to reflect correctly the current clock frequency, there is an intermediate level faked. Thus on forcing level setting, we need to treat level 2 correctly as level 1.
