Subject: [PATCH 6/7] drm/i915: Use plane state for primary plane updates.
Date: Thu, 7 Jan 2016 11:54:11 +0100 [thread overview]
Message-ID: <1452164052-21752-7-git-send-email-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <1452164052-21752-1-git-send-email-maarten.lankhorst@linux.intel.com>
Pass in the atomic states to allow for proper updates.
This removes uses of intel_crtc->config and direct access
to plane->state.
This breaks the last bit of kgdboc, but that appears to be dead code.
