Subject: [PATCH 6/9] drm/amd/display: Add debug param to force dio disable
Date: Fri, 25 Sep 2020 10:54:52 -0400	[thread overview]
Message-ID: <20200925145455.2398170-7-Rodrigo.Siqueira@amd.com> (raw)
In-Reply-To: <20200925145455.2398170-1-Rodrigo.Siqueira@amd.com>

From: Wesley Chalmers <Wesley.Chalmers@amd.com>

[WHY]
At the moment, some tests are failing because cur_link_settings is
invalid. As a workaround, add an option to force dio disable.
