Re: How to use the IPU6 webcam with kernel 6.10+?

Sorry to bring even more pessimism, after upgrading to 6.10, using using Dell XPS 13 Plus (9320) the camera doesn't even seem to be recognized.

Have anyone with that laptop got something else?

I'm using the same laptop, the camera isn't recognized too.

dmesg:

> sudo dmesg | grep ipu6
[    1.764285] intel-ipu6 0000:00:05.0: enabling device (0000 -> 0002)
[    1.764485] intel-ipu6 0000:00:05.0: IPU6 in non-secure mode touch 0x0 mask 0xff
[    1.764518] intel-ipu6 0000:00:05.0: Direct firmware load for intel/ipu/ipu6ep_fw.bin failed with error -2
[    1.764521] intel-ipu6 0000:00:05.0: error -ENOENT: Requesting signed firmware intel/ipu/ipu6ep_fw.bin failed
[    1.764523] intel-ipu6 0000:00:05.0: probe with driver intel-ipu6 failed with error -2

I got the same error because the firmware was stored on an encrypted device. I fixed it by adding the complete path to the firmware in FILES array of mkinitcpio.conf (and generate again the image). I don't know wether it is a valid solution, but the firmware is now loaded.

Re: How to use the IPU6 webcam with kernel 6.10+?

Have you installed external intel driver package?

In my my dmesg (running on XPS 9320 6.10.7-arch1-1) i have only:

lvanni@XPS-LV:~$ sudo dmesg | grep ipu6
[   16.820656] intel-ipu6 0000:00:05.0: enabling device (0000 -> 0002)

[   16.834005] intel-ipu6 0000:00:05.0: FW version: 20230925
.....

and my camera isn't working too.

Re: How to use the IPU6 webcam with kernel 6.10+?

According to this debian bug (https://bugs.debian.org/cgi-bin/bugrepo … ug=1074441), it seems that IPU6 is only fully functional with kernel 6.11. Is this the case for Archlinux?

I don't see how that issue is relevant, I have all those config flags set in my 6.10.5 kernel and still no camera, at least not in an XPS 13+

I have the same output but also the one with

Re: How to use the IPU6 webcam with kernel 6.10+?

So I have been doing some research because I have the same problem where the camera is not recognized (running on Manjaro 6.10 on a Dell Precision 5490). It seems that dkms is failing when building the drivers. In fact if I run

sudo dkms autoinstall -k $(uname -r)

this is the output:

If I take a look at the log, this is what is shown:

So there seems to be a problem with the driver itself. If you guys could try the same so we can see if that's actually the problem here it would be great!

I've tried on my archlinux system. I was not using dkms, I've installed it and run the sudo dkms autoinstall -k $(uname -r) command which exits immediately without any message.

I do not know if it is related, but since some days in the dmesg I got this error:

vsc-tp spi-INTC1094:00: probe with driver vsc-tp failed with error -22

That seems related to the ipu6 somehow.

Re: How to use the IPU6 webcam with kernel 6.10+?

Just adding 0.02 here, from a read of that Debian bug, I checked the config for 6.10.9-arch1-2 and it looks like Arch has everything needed enabled:

% for mod in `cat mod.txt`
do
zcat /proc/config.gz | grep $mod
done
CONFIG_INTEL_MEI_VSC_HW=m
CONFIG_INTEL_MEI_VSC_HW=m
CONFIG_INTEL_MEI_VSC=m
CONFIG_I2C_LJCA=m
CONFIG_SPI_LJCA=m
CONFIG_GPIO_LJCA=m
CONFIG_INTEL_VSC=m
CONFIG_IPU_BRIDGE=m
CONFIG_VIDEO_OV2740=m
CONFIG_USB_LJCA=m
CONFIG_VIDEO_INTEL_IPU6=m

I have a new Dell Latitude 7450 from work and the camera still doesn't work on it, even though everything looks like it's loaded properly and I see no firmware errors in dmesg etc.
