Subject: [PATCH 0/9] Enable upfront link training on DDI platforms
Date: Mon, 8 Aug 2016 19:33:09 -0700 [thread overview]
Message-ID: <1470709998-10751-1-git-send-email-manasi.d.navare@intel.com> (raw)
This patch series enables upfront link training on DDI platforms
(SKL/BDW/HSW/BXT). They are based on some of the pacthes submitted
earlier by Ander and Durgadoss.
The upfront link training had to be factored out of long pulse
hanlder because of deadlock issues seen on DP MST cases.
Now the upfront link training takes place in intel_dp_mode_valid()
to find the maximum lane count and link rate at which the DP link
can be successfully trained. These values are used to prune the
invalid modes before modeset. Modeset makes use the upfront lane
count and link train values.
These patches have been validated for DP SST on DDI platforms
(SKL/HSW/BDW/BXT). They have also been tested for any regressions
on non DDI platforms (CHV).
