AMD IPU Camera Not Detected on Acer Nitro ANV16S-41 (Fedora 44)
Summary
The internal webcam on an Acer Nitro ANV16S-41 laptop is not detected under Fedora 44.
The system detects an AMD IPU device, but no V4L2 camera device is created.
Hardware
- Laptop: Acer Nitro ANV16S-41
- CPU/APU: AMD Ryzen 7 260 with Radeon 780M Graphics
- GPU: AMD Radeon 780M
- Manufacturer: Acer
Software
- Distribution: Fedora 44
- Kernel:
7.1.5-200.fc44.x86_64
Symptoms
No camera devices are available:
$ v4l2-ctl --list-devices
(no output)
No video devices exist:
/dev/video\*
No media devices exist:
/dev/media\*
PCI Device Detection
The AMD IPU device is detected:
66:00.1 Signal processing controller:
Advanced Micro Devices, Inc. \[AMD\]
AMD IPU Device \[1022:1502\]
Driver binding:
Kernel driver in use: amdxdna
Kernel modules: amdxdna
Driver Observation
The loaded driver is:
amdxdna
This appears to be the AMD XDNA/NPU driver and does not expose a camera pipeline.
No AMD camera V4L2 driver is loaded.
Kernel Configuration
Camera framework is enabled:
CONFIG_MEDIA_CAMERA_SUPPORT=y
CONFIG_VIDEO_CAMERA_SENSOR=y
CONFIG_MEDIA_CONTROLLER=y
Available IPU camera drivers are Intel-specific:
CONFIG_VIDEO_IPU3_CIO2=m
CONFIG_VIDEO_INTEL_IPU6=m
CONFIG_VIDEO_INTEL_IPU7=m
No AMD IPU camera V4L2 driver is present.
Additional Checks
Acer WMI driver loaded:
acer_wmi
No camera-related Acer WMI controls found.
No ACPI camera device exposed:
/sys/bus/acpi/devices/
No camera/IPU/sensor entries found.
I2C buses are available, but no camera sensor device was detected.
Expected Behavior
The internal webcam should appear as:
/dev/video0
and be accessible through:
- V4L2
- libcamera
- PipeWire camera portal
Possible Cause
The AMD IPU camera pipeline support for this hardware may be missing from the current Linux kernel.
The system appears to require:
- AMD IPU camera driver support
- AMD ISP/V4L2 integration
- Proper ACPI firmware exposure for the camera sensor
Request
Please investigate support for:
AMD IPU Device \[1022:1502\]
on AMD Phoenix/Hawk Point platforms.
