Subject: [RFC 14/17] drm/amdgpu: use dma-fence annotations for gpu reset code
Date: Tue, 12 May 2020 10:59:41 +0200 [thread overview]
Message-ID: <20200512085944.222637-15-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20200512085944.222637-1-daniel.vetter@ffwll.ch>
To improve coverage also annotate the gpu reset code itself, since
that's called from other places than drm/scheduler (which is already
annotated). Annotations nests, so this doesn't break anything, and
allows easier testing.
