And perhaps not all properties will be\n> available on every pipeline ? Or have I missed something obvious...\n>\n> This seems odd to me at the moment ;(\n\nIt is, it has puzzled me for the last hour or so.\n\nMy recollection was that every control list should be initialized with\nan idMap_ to support the id-based interface. The id-based interface is\nused by the CameraSensor to set/get controls on the subdevice and by\nclosed source IPAs that use custom controls.\n\nI'm currently failing to find is where the idmap_ is used in the whole\nControlList or ControlSerializer.\n\nI might have mixed up how the PipelineHandler::controls_ ControlInfoMap needs\nto be initialized to specify control limits for application-modifiable\nControlList associated with a Request, and how\nPipelineHandler::properties_, being immutable from application\nperspective, just need to be filled in with ControlValues (and being\napplication visibile, it should only be inspected using libcamera\ncontrols).\n\nI've tested without this change, and it seems not required.\nI'll keep looking as I've the feeling I'm really missing something\nnow, or got something mixed up at the time I implemented this.\n\n>\n> > Signed-off-by: Jacopo Mondi \n> > ---\n> > include/libcamera/internal/pipeline_handler.h | 3 ++-\n> > 1 file changed, 2 insertions(+), 1 deletion(-)\n> >\n> > diff --git a/include/libcamera/internal/pipeline_handler.h b/include/libcamera/internal/pipeline_handler.h\n> > index a4e1b529c461..e579da711b33 100644\n> > --- a/include/libcamera/internal/pipeline_handler.h\n> > +++ b/include/libcamera/internal/pipeline_handler.h\n> > @@ -17,6 +17,7 @@\n> >\n> > #include \n> > #include \n> > +#include \n> > #include \n> >\n> > #include \"libcamera/internal/ipa_proxy.h\"\n> > @@ -37,7 +38,7 @@ class CameraData\n> > {\n> > public:\n> > \texplicit CameraData(PipelineHandler *pipe)\n> > -\t\t: pipe_(pipe)\n> > +\t\t: pipe_(pipe), properties_(properties::properties)\n> > \t{\n> > \t}\n> > \tvirtual ~CameraData() {}\n> >\n>\n> --\n> Regards\n> --\n> Kieran","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 E3242BEEE0\n\tfor ;\n\tThu, 8 Oct 2020 10:21:01 +0000 (UTC)","from lancelot.ideasonboard.com (localhost [IPv6:::1])\n\tby lancelot.ideasonboard.com (Postfix) with ESMTP id 5747B605BD;\n\tThu, 8 Oct 2020 12:21:01 +0200 (CEST)","from relay9-d.mail.gandi.net (relay9-d.mail.gandi.net\n\t[217.70.183.199])\n\tby lancelot.ideasonboard.com (Postfix) with ESMTPS id EBAD660391\n\tfor ;\n\tThu, 8 Oct 2020 12:20:59 +0200 (CEST)","from uno.localdomain (93-34-118-233.ip49.fastwebnet.it\n\t[93.34.118.233]) (Authenticated sender: jacopo@jmondi.org)\n\tby relay9-d.mail.gandi.net (Postfix) with ESMTPSA id 48F6BFF805;\n\tThu, 8 Oct 2020 10:20:58 +0000 (UTC)"],"X-Originating-IP":"93.34.118.233","Date":"Thu, 8 Oct 2020 12:24:58 +0200","From":"Jacopo Mondi ","To":"Kieran Bingham ","Message-ID":"<20201008102458.zp44tgk5a3ot4t7f@uno.localdomain>","References":"<20200911162039.61933-1-jacopo@jmondi.org>\n\t<20200911162039.61933-5-jacopo@jmondi.org>\n\t","MIME-Version":"1.0","Content-Disposition":"inline","In-Reply-To":"","Subject":"Re: [libcamera-devel] [RFC 4/6] libcamera: pipeline_handler:\n\tInitialize properties_","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","Cc":"hanlinchen@chromium.org, libcamera-devel@lists.libcamera.org","Content-Type":"text/plain; charset=\"us-ascii\"","Content-Transfer-Encoding":"7bit","Errors-To":"libcamera-devel-bounces@lists.libcamera.org","Sender":"\"libcamera-devel\" "}}]
