From 23526249fc4ef1810d3567ff52ed7606f3548517 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 27 Nov 2019 21:05:55 +0200 Subject: [PATCH] drm/i915: Nuke intel_pre_disable_primary_noatomic() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Let's just inline intel_pre_disable_primary_noatomic() into intel_plane_disable_noatomic(). The CxSR disable we can do regardless of which plane we're disabling, and while at it we can make the gen2 underrun w/a accurate by consulting the active_planes bitmask.
