Subject: [PATCH v2 08/14] media: staging: rkisp1: params: set vb.sequence to be the isp's frame_sequence + 1
Date: Sat, 15 Aug 2020 12:37:28 +0200 [thread overview]
Message-ID: <20200815103734.31153-9-dafna.hirschfeld@collabora.com> (raw)
In-Reply-To: <20200815103734.31153-1-dafna.hirschfeld@collabora.com>
The params isr is called when a frame is out of the isp. The parameters
are applied immediately since the isr updates the shadow registers.
Therefore the params are first applied on the next frame.
We want the vb.sequence to be the frame that the params are applied to.
So we set vb.sequence to be the isp's frame_sequence + 1
