Subject: [PATCH 0/3] drm/i915: MST link training locking and cleanups
Date: Thu, 27 Aug 2015 18:36:47 +0300 [thread overview]
Message-ID: <1440689810-29585-1-git-send-email-ville.syrjala@linux.intel.com> (raw)
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
While glancing at the MST hpd code I noticed we have no locking in there
to protect the link retraining against a concurrent modeset. So I added some,
and then ocd struct and had to clean up the code a bit.
These patches are available at
git://github.com/vsyrjala/linux.git mst_fixes_cleanups
In the repo I've also included an earlier patch which attempts to enable
the DDI PLL for MST on SKL [1]
