Subject: [PATCH v2 3/5] drm/nouveau/kms/gv100-: Add support for interlaced modes
Date: Fri, 14 Feb 2020 17:58:54 -0500	[thread overview]
Message-ID: <20200214225910.695210-4-lyude@redhat.com> (raw)
In-Reply-To: <20200214225910.695210-1-lyude@redhat.com>

We advertise being able to set interlaced modes, so let's actually make
sure to do that. Otherwise, we'll end up hanging the display engine due
to trying to set a mode with timings adjusted for interlacing without
telling the hardware it's actually an interlaced mode.
