Subject: [PATCH 09/10] drm/i915: Add debugfs entries for reading out DPCD DSC and FEC.
Date: Wed, 21 Aug 2019 15:32:20 +0200 [thread overview]
Message-ID: <20190821133221.29456-10-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <20190821133221.29456-1-maarten.lankhorst@linux.intel.com>
Dump the DSC and FEC in i915_dpcd as well. This is useful when
debugging the link caps.
