Public bug reported: The following bug report is created with the help of Claude.ai. I don't have the expertise to dig deep into the problem. Hopefully, the information provided below will help resolve this issue
The integrated webcam (Intel MIPI camera with OV02C10 sensor) on Dell XPS 9350 (2024) with Intel Core Ultra 7 258V (Lunar Lake) does not work on Ubuntu 24.04 due to missing GPIO controller driver support for INTC10B5. Hardware: Laptop: Dell XPS 13 9350 (2024 model) CPU: Intel Core Ultra 7 258V (Lunar Lake) Camera: OV02C10 sensor via Intel IPU7 GPIO Controller: INTC10B5:00 (ACPI device) Ubuntu Version: Distribution: Ubuntu 24.04 LTS Kernel: 6.14.0-1015-oem Problem Description: The camera sensor (OVTI02C1:00) is detected by the kernel and the Intel IPU7 driver reports "Found supported sensor OVTI02C1:00", but the sensor cannot initialize because the required GPIO controller (INTC10B5) has no driver binding to it. The pinctrl-intel-platform driver exists in the kernel but only supports INTC105F, not INTC10B5. Without the GPIO controller driver, the camera sensor cannot be powered on or controlled. Steps to Reproduce: Boot Dell XPS 9350 (2024) with Ubuntu 24.04 Try to use camera in any application (Cheese, Zoom, browser, etc.) Camera is detected but shows blank screen Expected Behavior: Camera should work as it does in Windows Actual Behavior: Camera HAL reports: "No sensors available" ACPI device INTC10B5:00 exists but has no driver bound Error in dmesg: "int3472-discrete INT3472:00: cannot find GPIO chip INTC10B5:00, deferring" Technical Details: $ cat /sys/bus/acpi/devices/INTC10B5:00/hid INTC10B5 $ modinfo pinctrl_intel_platform | grep alias alias: acpi*:INTC105F:* $ ls -la /sys/bus/platform/devices/INTC10B5:00/driver ls: cannot access '/sys/bus/platform/devices/INTC10B5:00/driver': No such file or directory $ sudo dmesg | grep OVTI02C1 [ 22.434305] intel-ipu7 intel-ipu7: Found supported sensor OVTI02C1:00 $ sudo dmesg | grep INTC10B5 [ 277.581723] int3472-discrete INT3472:00: cannot find GPIO chip INTC10B5:00, deferring Packages Installed: All IPU7 camera packages from ppa:oem-solutions-group/intel-ipu7 libcamhal-ipu7x (version 0git202510170946.ec24db2-1ubuntu24.04.1) linux-modules-ipu7-oem-24.04c gstreamer1.0-icamera v4l2loopback Root Cause: The drivers/pinctrl/intel/pinctrl-intel-platform.c driver needs to be updated to add INTC10B5 to its ACPI device ID table. This GPIO controller is specific to Lunar Lake platforms. Workaround: None currently available. Camera works in Windows.
