From b82a682d3234115dda6c8d05c31bafe98a66c885 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 1 Jun 2017 17:36:18 +0300 Subject: [PATCH] drm/i915: Drop pipe A quirk for Thinkapd T60 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The pipe A force quirk shouldn't needed except on 830. So let's nuke it for the IBM Thinkpad T60 945 machines. This quirk pre-dates KMS so it's usefulness is doubtful at best now. The original bug report [1] describes the symptoms as "system hang on closing T60 panel lid", and we already dropped a similar quirk for another 945 machine in commit 736a69ca8c99 ("drm/i915: Drop PIPE-A quirk for 945GSE HP Mini") so I'm hopeful we can drop this one as well. The quirk was added into xf86-video-intel in commit 08903abe4dc0 ("Add pipe a force enable quirk for Lenovo T60") [1] https://bugs.freedesktop.org/show_bug.cgi?id=16494 Signed-off-by: Ville Syrjälä Link: http://patchwork.freedesktop.org/patch/msgid/20170601143619.27840-7-ville.syrjala@linux.intel.com Acked-by: Chris Wilson Acked-by: Maarten Lankhorst --- drivers/gpu/drm/i915/intel_display.c | 3 --- 1 file changed, 3 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index f84691fb909d..c3d9c8e511c6 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -14817,9 +14817,6 @@ static const struct intel_dmi_quirk intel_dmi_quirks[] = { }; static struct intel_quirk intel_quirks[] = { - /* ThinkPad T60 needs pipe A force quirk (bug #16494) */ - { 0x2782, 0x17aa, 0x201a, quirk_pipea_force }, - /* 830 needs to leave pipe A & dpll A up */ { 0x3577, PCI_ANY_ID, PCI_ANY_ID, quirk_pipea_force }, -- 2.11.0
