Subject: [PATCH v5 2/2] drm/nouveau/kms/nv50-: Log SOR/PIOR caps
Date:   Fri,  4 Sep 2020 16:27:59 -0400
Message-Id: <20200904202813.1260202-2-lyude@redhat.com>
In-Reply-To: <20200904202813.1260202-1-lyude@redhat.com>

Precedence: bulk

Since I'm almost certain I didn't get capability checking right for
pre-volta chipsets, let's start logging any caps we find to make things
like this obvious in the future.
