Subject: [PATCH AUTOSEL 4.14 55/95] drm/i915: Downgrade Gen9 Plane WM latency error
Date: Tue, 7 May 2019 01:37:44 -0400 [thread overview]
Message-ID: <20190507053826.31622-55-sashal@kernel.org> (raw)
In-Reply-To: <20190507053826.31622-1-sashal@kernel.org>
From: Chris Wilson <chris@chris-wilson.co.uk>
[ Upstream commit 86c1c87d0e6241cbe35bd52badfc84b154e1b959 ]
According to intel_read_wm_latency() it is perfectly legal for one WM
and all subsequent levels to be 0 (and the deeper powersaving states
disabled), so don't shout *ERROR*, over and over again.
