From 5f080c0f4bd526b36361dd15c4d22f6bbad95af9 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 15 Aug 2014 01:22:06 +0300 Subject: [PATCH] Revert "drm/i915: Nuke pipe A quirk on i830M" MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 830 really does want the pipe A quirk. The planes and ports don't react to any register writes unless the pipe currently attached to them is running, so it's impossible to move them to the other pipe unless both pipes are running. Also it's documented that the DPLL must be enabled on both pipes whenever it's needed. This reverts commit ac6696d3236bd61503f89a1a99680fd7894d5d53.
