It should be one of these: https://hverkuil.home.xs4all.nl/spec/uapi/mediactl/media-types.html#media-entity-type However, we don't have a proper function defined. I would suggest adding a new MEDIA_ENT_F_DTV_DECODER analogous to MEDIA_ENT_F_ATV_DECODER. It would be a new patch adding this + documentation. > Pad 0x01000004 : Source > Link 0x0200006f: to remote pad 0x1000063 of entity 'ipu1_csi0_mux': > Data > > Compliance test for device /dev/v4l-subdev1: > > Allow for multiple opens: > test second /dev/v4l-subdev1 open: OK > test for unlimited opens: OK > > Debug ioctls: > test VIDIOC_LOG_STATUS: OK > > Input ioctls: > test VIDIOC_G/S_TUNER/ENUM_FREQ_BANDS: OK (Not Supported) > test VIDIOC_G/S_FREQUENCY: OK (Not Supported) > test VIDIOC_S_HW_FREQ_SEEK: OK (Not Supported) > test VIDIOC_ENUMAUDIO: OK (Not Supported) > test VIDIOC_G/S/ENUMINPUT: OK (Not Supported) > test VIDIOC_G/S_AUDIO: OK (Not Supported) > Inputs: 0 Audio Inputs: 0 Tuners: 0 > > Output ioctls: > test VIDIOC_G/S_MODULATOR: OK (Not Supported) > test VIDIOC_G/S_FREQUENCY: OK (Not Supported) > test VIDIOC_ENUMAUDOUT: OK (Not Supported) > test VIDIOC_G/S/ENUMOUTPUT: OK (Not Supported) > test VIDIOC_G/S_AUDOUT: OK (Not Supported) > Outputs: 0 Audio Outputs: 0 Modulators: 0 > > Input/Output configuration ioctls: > test VIDIOC_ENUM/G/S/QUERY_STD: OK (Not Supported) > test VIDIOC_ENUM/G/S/QUERY_DV_TIMINGS: OK > test VIDIOC_DV_TIMINGS_CAP: OK > test VIDIOC_G/S_EDID: OK Nice! > > Sub-Device ioctls (Source Pad 0): > test Try VIDIOC_SUBDEV_ENUM_MBUS_CODE/FRAME_SIZE/FRAME_INTERVAL: OK > test Try VIDIOC_SUBDEV_G/S_FMT: OK > test Try VIDIOC_SUBDEV_G/S_SELECTION/CROP: OK (Not Supported) > test Active VIDIOC_SUBDEV_ENUM_MBUS_CODE/FRAME_SIZE/FRAME_INTERVAL: OK > test Active VIDIOC_SUBDEV_G/S_FMT: OK > test Active VIDIOC_SUBDEV_G/S_SELECTION/CROP: OK (Not Supported) > test VIDIOC_SUBDEV_G/S_FRAME_INTERVAL: OK (Not Supported) > > Control ioctls: > test VIDIOC_QUERY_EXT_CTRL/QUERYMENU: OK (Not Supported) > test VIDIOC_QUERYCTRL: OK (Not Supported) > test VIDIOC_G/S_CTRL: OK (Not Supported) > test VIDIOC_G/S/TRY_EXT_CTRLS: OK (Not Supported) > test VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT: OK (Not Supported) > test VIDIOC_G/S_JPEGCOMP: OK (Not Supported) > Standard Controls: 0 Private Controls: 0 Why doesn't this show anything? You have at least one control, so this should reflect that. Does 'v4l2-ctl -d /dev/v4l-subdev1 -l' show any controls? I think sd->ctrl_handler is never set to the v4l2_ctrl_handler pointer. Have you ever tested the controls? Looking closer I also notice that the control handler is never freed. Or checked for errors when it is created in the probe function. Hmm, I should have caught that earlier. Regards, Hans
