[ Test Plan ] 1. Install the dkms from -proposed pocket. The corresponding binary kernel module should be built automatically; if not, run: ``` $ sudo dkms install --force ipu6-drivers/0~git202506270118.9bff7368 -k $(uname -r) ``` 2. Reboot to the same kernel to reload the drivers. 3. Make sure the device is probed and up running: ``` $ media-ctl -p Media controller API version 6.14.8 Media device information ------------------------ driver intel-ipu7 model ipu7 serial bus info PCI:intel-ipu7 hw revision 0x17aa233b driver version 6.14.8 ... ``` 4. Use https://webcamtests.com to verify the camera is really capable of streaming. [ Where problems could occur ] This fills the probe procedure as other similar camera sensors do. No known problem so far. [ Other Info ] This is a follow-up for bug 2107320 that supports IMX471 in linux- oem-6.11 and on. Nominate for Plucky, Questing for ipu6-drivers, which will be compiled within linux-oem-6.11 and on. ========== original bug report ========== This is a follow-up for bug 2107320, support Sony IMX471 camera sensor for Intel IPU7 platforms.
