Subject: [PATCH 02/11] drm/vkms: Annotate vblank timer
Date: Thu, 21 Jan 2021 16:29:50 +0100	[thread overview]
Message-ID: <20210121152959.1725404-3-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20210121152959.1725404-1-daniel.vetter@ffwll.ch>

This is needed to signal the fences from page flips, annotate it
accordingly. We need to annotate entire timer callback since if we get
stuck anywhere in there, then the timer stops, and hence fences stop.
Just annotating the top part that does the vblank handling isn't
enough.
