$ cat /sys/bus/i2c/devices/i2c-SONY471A\:00/modalias
acpi:SONY471A:SONY471A:

[ Test Plan ]

1. Install -proposed kernel oem-6.11/noble or linux-oem-6.14/noble
```
$ sudo apt-get install --no-install-recommends --yes \
    linux-oem-22.04b \
    linux-modules-ipu6-oem-22.04b \
    linux-modules-ipu7-oem-22.04b \
    linux-modules-usbio-oem-22.04b \
    linux-modules-vision-oem-22.04b
$ sudo apt-get install --no-install-recommends --yes \
    linux-oem-22.04c \
    linux-modules-ipu6-oem-22.04c \
    linux-modules-ipu7-oem-22.04c \
    linux-modules-usbio-oem-22.04c \
    linux-modules-vision-oem-22.04c
```

2. To verify dkms changes, install -proposed intel-ipu6-dkms.
```
$ sudo apt-get install --no-install-recommends --yes intel-ipu6-dkms
```

3. Check if the driver has correctly bound:
```
$ sudo dmesg|grep ipu

```

4. Try access via gstreamer plugin via the video device hidden from general users:
```
$ sudo gst-launch-1.0 icamerasrc ! \
    video/x-raw,format=NV12,width=1280,height=720 ! \
    videoconvert ! \
    autovideosink
```

5. Try access webcam from https://webcamtests.com

[ Where problems could occur ]

The changes only take effect for kernels >= v6.10. And while this is a new driver that is not yet upstreamed, it's has no effect to existing systems.

[ Other Info ]

Targets Questing and Plucky because all the oem-6.11/noble, oem-6.14/noble, linux/plucky kernels compile against intel-ipu6-dkms from Plucky.

Hello You-Sheng, or anyone else affected,

Accepted ipu6-drivers into plucky-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/ipu6-drivers/0~git202411190607.0ad49882-0ubuntu4~25.04.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-plucky to verification-done-plucky. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-plucky. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

[Timo Aaltonen (tjaalton)]

The verification of the Stable Release Update for ipu6-drivers has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-oem-6.11/6.11.0-1023.23 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-done-noble-linux-oem-6.11'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-failed-noble-linux-oem-6.11'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
