Perhaps we really need to have either some automated testing on\nreal i.MX8MP devices, or maybe I should have pushed back and asked for a\nseparate Tested-by: tag from another NXP/ISI user ... still - hopefully\nthis won't break things for anyone else ;-)\n\nAnyway, as you're @NXP, and therefore pretty close to being considerable\nas a maintainer for the ISI pipeline handler - along with a review by\ntag from Laurent....\n\nI've merged this.\n\n--\nKieran\n\n\n\n> Best regards\n> Antoine\n> \n> > \n> > --\n> > Kieran\n> > \n> >> Best regards\n> >> Antoine\n> >>\n> >> Antoine Bouyer (2):\n> >> pipeline: imx8-isi: Add constexpr for maximum pipeline and resize if\n> >> needed\n> >> pipeline: imx8-isi: Add multicamera support\n> >>\n> >> src/libcamera/pipeline/imx8-isi/imx8-isi.cpp | 119 ++++++++++++-------\n> >> 1 file changed, 79 insertions(+), 40 deletions(-)\n> >>\n> >> --\n> >> 2.34.1\n> >>\n>","headers":{"Return-Path":"","X-Original-To":"parsemail@patchwork.libcamera.org","Delivered-To":"parsemail@patchwork.libcamera.org","Received":["from lancelot.ideasonboard.com (lancelot.ideasonboard.com\n\t[92.243.16.209])\n\tby patchwork.libcamera.org (Postfix) with ESMTPS id 6E15FC3237\n\tfor ;\n\tMon, 21 Jul 2025 16:22:18 +0000 (UTC)","from lancelot.ideasonboard.com (localhost [IPv6:::1])\n\tby lancelot.ideasonboard.com (Postfix) with ESMTP id F282C68FF7;\n\tMon, 21 Jul 2025 18:22:16 +0200 (CEST)","from perceval.ideasonboard.com (perceval.ideasonboard.com\n\t[IPv6:2001:4b98:dc2:55:216:3eff:fef7:d647])\n\tby lancelot.ideasonboard.com (Postfix) with ESMTPS id B808968FE5\n\tfor ;\n\tMon, 21 Jul 2025 18:22:14 +0200 (CEST)","from pendragon.ideasonboard.com\n\t(cpc89244-aztw30-2-0-cust6594.18-1.cable.virginm.net [86.31.185.195])\n\tby perceval.ideasonboard.com (Postfix) with ESMTPSA id A0BEF7940;\n\tMon, 21 Jul 2025 18:21:37 +0200 (CEST)"],"Authentication-Results":"lancelot.ideasonboard.com; dkim=pass (1024-bit key;\n\tunprotected) header.d=ideasonboard.com header.i=@ideasonboard.com\n\theader.b=\"fA+Te9f/\"; dkim-atps=neutral","DKIM-Signature":"v=1; a=rsa-sha256; c=relaxed/simple; d=ideasonboard.com;\n\ts=mail; t=1753114897;\n\tbh=aVx+9tUOzQMxg924sXUWTGqwUWJy4x9CJZwTCAEtZew=;\n\th=In-Reply-To:References:Subject:From:Cc:To:Date:From;\n\tb=fA+Te9f/q6i2uJa3cFPMuKEZ9u7ydW2SviiJpJWlBMlCjp/R0U7w1GKubY9QMxcNA\n\tCGcO/FMYoFytgV53X2OIuC/1SSj/1H1Ky27irde30opYgpdw6L6MaEXoEVyFwOErva\n\tWUo96NZBsvhXATh+fPyfxGaPdP4m/GHpSqwx1WC4=","Content-Type":"text/plain; charset=\"utf-8\"","MIME-Version":"1.0","Content-Transfer-Encoding":"quoted-printable","In-Reply-To":"<46b3a4a7-b4f8-4fd3-b498-1215338e60e5@nxp.com>","References":"<20250701085818.2447600-1-antoine.bouyer@nxp.com>\n\t<175284518492.560048.2748562905289040990@ping.linuxembedded.co.uk>\n\t<46b3a4a7-b4f8-4fd3-b498-1215338e60e5@nxp.com>","Subject":"Re: [PATCH v4 0/2] pipeline: imx8-isi: Add multicamera support","From":"Kieran Bingham ","Cc":"julien.vuillaumier@nxp.com","To":"Antoine Bouyer ,\n\tlibcamera-devel@lists.libcamera.org","Date":"Mon, 21 Jul 2025 17:22:12 +0100","Message-ID":"<175311493233.50296.3278977077656568704@ping.linuxembedded.co.uk>","User-Agent":"alot/0.9.1","X-BeenThere":"libcamera-devel@lists.libcamera.org","X-Mailman-Version":"2.1.29","Precedence":"list","List-Id":"","List-Unsubscribe":",\n\t","List-Archive":"","List-Post":"","List-Help":"","List-Subscribe":",\n\t","Errors-To":"libcamera-devel-bounces@lists.libcamera.org","Sender":"\"libcamera-devel\" "}}]
