From 0a7000cc96ad26e01efc4b204d90ce3a9734ea06 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Niklas=20S=C3=B6derlund?= Date: Tue, 3 Nov 2020 01:09:24 +0100 Subject: libcamera: ipa: ipu3: Add an IPA skeleton for the IPU3 pipeline MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add an empty IPA skeleton for the IPU3 pipeline. The skeleton IPA handles the flow of parameter and statistic buffers but does not read or write anything in the buffers. It also allows the IPA to set sensor controls but does not implement any logic to set optimal values and instead sets the V4L2 exposure and gain controls to max and keeps them at that setting. This IPA is meant as a base to allow the pipeline handler to be wired up to an IPA. The image algorithms can then later be added to the IPA independently from also having to add plumbing to the pipeline handler.
