Description Hans de Goede 2024-12-19 10:08:05 UTC

Some Meteor Lake (confirmed) and Lunar Lake (?) laptop models use a new camera "glue" chip from Intel replacing the LJCA IO-expander and the VSC vision chips.

In order for IPU6/IPU7 based cameras to be able to work on these laptops support for these glue chips needs to be added to the kernel.

Examples of laptop models with this chip are the Dell Latitude 7450 and Lenovo ThinkPad X1 Carbon Gen 12.

Out if tree drivers for this chip are available here:
https://github.com/intel/usbio-drivers/

These drivers need work before they can be submitted upstream, see e.g. :
https://github.com/intel/usbio-drivers/issues/6


Reproducible: Always

Comment 1 Hans de Goede 2025-09-30 16:09:55 UTC

Good news the just released 6.17 kernel has support for the IPU7 CSI2
receiver and the missing USBIO drivers have recently landed in linux-next.
I have backported the USBIO drivers + a few other camera fixes to
the Fedora 6.17 kernel:

https://gitlab.com/cki-project/kernel-ark/-/merge_requests/4105

I've also prepared an updated libcamera-0.5.2 Fedora package with support
for IPU7 (Lunar Lake) CSI2 receivers as well as backporting a set of
upstream SwStats and AGC fixes, fixing various crashes as well as the
bad flicker MIPI camera users have been hitting with libcamera 0.5.2.

Together these 2 updates should make the FOSS MIPI camera support work on
most Meteor Lake, Lunar Lake and Arrow Lake laptops:

https://bodhi.fedoraproject.org/updates/FEDORA-2025-a2b653cff6
https://bodhi.fedoraproject.org/updates/FEDORA-2025-bdeff04027

Please install these updates, disable the proprietary stack from rpmfusion
(if installed) by running: "sudo ipu6-driver-select foss", reboot and
give the new drivers a try by running qcam, snapshot or video-conferencing
in Firefox. After testing please report the testing results in this bug.

If things work well for you please leave positive feedback on the updates
in bodhi.

Note snapshot on Lunar Lake triggers a bug in the LNL Vulkan code,
to avoid this start snapshot from a terminal with:

GSK_RENDERER=gl snapshot

Comment 2 Hans de Goede 2025-10-03 20:52:27 UTC

The new UBIO driver support on the Fedora 6.17.0 kernels has been tested successfully by several users now -> closing.
