From 7d0bc1ea50e7b3fb1c7a52918611baba8750177d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 16 Sep 2013 17:38:33 +0300 Subject: [PATCH] drm/i915: Redisable VGA before the modeset on resume MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The VGA plane needs to be disabled before we start doing any modeset operations on resume. This should also guarantee that the power well will be enabled when we call i915_redisable_vga() since it gets explicitly powered on during resume, and will get powered back off during the modeset operation if no longer needed.
