| bemug | Hey, should my camera sensor driver controls be available through /dev/video0 ? From my understanding /dev/video0 is a video device, not a subdevice, and therefore if I want to access my camera sensor driver control (the subdevice) I have to perform ioctls on /dev/v4l-subdevX
But this is not necessary in RPI, I guess that's unicam magic ? Or do I miss something in my camera sensor driver to inherit subdevice controls ? | [09:45] |
| pinchartl | there's support for control inheritance in V4L2
using v4l2_ctrl_add_handler() but I don't recommend it and it's not a decision of the sensor driver anyway | [09:46] |
| bemug | iirc this is something to be done in the isp driver, and that's what unicam does right ? | [09:48] |
| pinchartl | I don't see that function called by unicam
at least not upstream it does in the rpi downstream kernel indeed | [09:49] |
| bemug | since this is not recommended it could have been removed from the upstream process
would make sense | [09:50] |
| pinchartl | I've probably removed it, yes :-) | [09:50] |
| bemug | thank you | [09:53] |
| *** | digetx has quit IRC (Quit: https://quassel-irc.org - Chat comfortably. Anywhere.) | [09:53] |
| bemug | pinchartl I still have a small the question, in the documentation it looks like the register_subdev() should automatically call add_handler(). Which does not seem to be the behavior we talked about. https://www.kernel.org/doc/html/latest/driver-api/media/v4l2-controls.html#inheriting-sub-device-controls | [10:01] |
| pinchartl | oh
pinchartl checks | [10:03] |
| *** | digetx has joined #linux-media | [10:03] |
| pinchartl | only if the v4l2_device has a ctrl_handler set
only 3 video capture drivers do so and 5 radio drivers I don't think that's recommended anymore either | [10:05] |
| *** | Mo_ has joined #linux-media | [10:08] |
| bemug | Ok I though it was automatically called by the register_subdev() by the code, but it looks more like a (outdated) guideline for drivers if I understand correctly | [10:10] |
| hverkuil | It's still recommended for drivers using a standard simple video pipeline. Lots of drivers set it: git grep v4l2_dev.*ctrl_handler
You don't notice because you don't work on such drivers :-) | [10:11] |
| bemug | Exactly :) Thank you | [10:13] |

| pinchartl | hverkuil: ah indeed I missed the drivers that use v4l2_dev.ctrl_handler, I only grepped for v4l2_dev->ctrl_handler
I wouldn't expect many new drivers to do that do we get new submissions for PCI capture cards these days ? | [11:59] |
| hverkuil | Very rarely. Same for usb. | [12:02] |
| pinchartl | I suppose TV isn't as big as it used to be | [12:03] |
| hverkuil | It's a shame, really. I'd love to have a good quality HDMI 4k capture USB or PCIe card. I.e. one that doesn't act like a UVC camera :-) | [12:04] |
| pinchartl | maybe cisco should make one ? :-) | [12:06] |
| hverkuil | We did for internal use (1080p only). The driver is actually in mainline: the cobalt driver. I still use it once in a while.
Sadly, we never made a 4k version :-( | [12:10] |
| pinchartl | ah, I didn't know the cobalt driver came from that, nice | [12:11] |
| hverkuil | Most of the general HDMI V4L2 support was developed using that hardware. | [12:11] |
