Subject: [PATCH v4 2/6] drm/virtio: notify before waiting
Date: Fri, 14 Feb 2020 13:55:31 +0100 [thread overview]
Message-ID: <20200214125535.26349-3-kraxel@redhat.com> (raw)
In-Reply-To: <20200214125535.26349-1-kraxel@redhat.com>
Before we are going to wait for virtqueue entries becoming available
call virtio_gpu_notify() to make sure the host has seen everything
we've submitted.
