Subject: [PATCH 39/43] drm/i915/crt: implement get_hw_state
Date: Tue, 3 Jul 2012 11:28:31 +0200 [thread overview]
Message-ID: <1341307715-3886-40-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <1341307715-3886-1-git-send-email-daniel.vetter@ffwll.ch>
Note that even though this connector is cloneable we have still can
use the exact same test to check whether the connector is on or
whether the output is enabled - both the dpms code and the encoder
disable/enable frob the exact same hw state.
For dvo/sdvo outputs, this will be different.
