Subject: [RFC PATCH 0/3] drm/i915: tell bios to update audio controller em4/5 values
Date: Tue, 1 Jul 2014 16:48:59 +0300 [thread overview]
Message-ID: <cover.1404222047.git.jani.nikula@intel.com> (raw)
Hi Mengdong -
Here's the first drafts towards fixing [1], but unfortunately this is
still Broadwell specific. Currently patch 2 is not needed, but is
included in case we'll need that too (maybe for Haswell?). Please
review/test, I don't have access to either hsw or bdw right now.
BR,
Jani.
