Hardware:
- Laptop: Lenovo 83CX (board: LNVNB161216), Intel Lunar Lake
- IPU: 00:05.0 Multimedia controller [0480]: Intel Corporation Lunar Lake IPU [8086:645d] (rev 04), bound to intel-ipu7
- Camera sensor ACPI device: OVTI32C4:00, _STA = 15 (present, enabled), i2c client instantiated at /sys/bus/i2c/devices/i2c-OVTI32C4:00
- Kernel: 7.0.14 (Fedora 43)
What I did:
Built and installed all four components from the IPU7 stack:
- ipu7-drivers (kernel module intel_ipu7 / intel_ipu7_isys - loaded and bound to the PCI IPU device correctly)
- ipu7-camera-bins (firmware + ia_imaging libs installed)
- ipu7-camera-hal (built and installed libcamhal.so, IPU_VERSIONS=ipu7x;ipu75xa;ipu8)
- icamerasrc (icamerasrc_slim_api branch, built against libcamhal, GStreamer plugin loads fine via gst-inspect-1.0 icamerasrc)
Everything up through the IPU7 core and media controller topology works: /dev/video* nodes exist, media-ctl -p shows 4x Intel IPU7 CSI2 N entities each fanning out to 8 capture nodes correctly.
Problem:
The camera sensor itself (OVTI32C4, identified as OmniVision OV32C - a 32MP RGBC "Always-On" sensor, likely used here as the front-facing webcam) has no matching driver:
- No alias for OVTI32C4 in this kernel's modules.alias
- No mention of 32C4/ov32c in any of the patches under ipu7-drivers/patch/*
- No sensor subdevice appears in the media graph (CSI2 sink pads stay SINK,MUST_CONNECT with no source link)
- libcamhal correctly detects the IPU (Found IPU: IPU7) but reports parseSensors: No sensors available
Ask:
Is there a driver for the OV32C sensor (ACPI HID OVTI32C4) planned or available out-of-tree? If so, could it be added to this repo (or pointed to), similar to the existing ov13b10/ov02c10
support? Happy to test on this hardware.
