Looks like this is the cause: https://lkml.iu.edu/hypermail/linux/kernel/2312.0/06197.html

I was able to build the module

cd /var/lib/dkms/bcwc-pcie/0.6.8.r2.g2b287d4/build
sudo vi fthd_v4l2.c

Then change line 686 from

q->min_buffers_needed = 1;

to

q->min_queued_buffers = 1;

and build with

sudo KERNELRELEASE=6.8.0-zen1-1-zen make
sudo sudo mkinitcpio -P

[edited] - after building and installing properly, confirming this change fixes the problem.

Had a similar issue today after Zen updates to linux-zen-6.8.zen1-1 & linux-zen-headers-6.8.zen1-1

==> dkms install --no-depmod bcwc-pcie/0.6.8.r2.g2b287d4 -k 6.8.0-zen1-1-zen

Checked the log referenced, and the error is:

/var/lib/dkms/bcwc-pcie/0.6.8.r2.g2b287d4/build/fthd_v4l2.c: In function ‘fthd_v4l2_register’:

  686 |         q->min_buffers_needed = 1;
      |          ^~

Looks like the change to the #include mentioned by vloq below has already been made permanent so doesn't help here.

Had the same problem as @rahulmb.

The following seems to solve the problem:

change

#include <media/videobuf-dma-sg.h>

to

#include <media/videobuf2-dma-sg.h>

in fthd_v4l2.h file.

I'm having trouble for some reason the package isn't building against linux-zen-headers . Anyone suggest troubleshooting steps I could try?

I am getting similar errors to nicoandresr, but these are occurring in the "Install DKMS modules" Pacman hook. The package builds just fine, but isn't installable.

@nicoandresr, I checked the build (makepkg) on a system with linux 6.1.12.arch1-1 and could not reproduce your issue; it builds fine.

I am actually using this driver on a machine running the 5.10.xxx-lts Linux kernel series. That works, too (including the build, which I do locally).

I'm getting this error on Kernel 6.1+

==> ERROR: Missing 6.1.6-arch1-3 kernel modules tree for module bcwc-pcie/0.5.18.r0.g75a2a58.

I solved my issue installing and switching to linux-lts kernel:

sudo pacman -S linux-lts linux-headers-lts

I'm using systemd-boot instead of grub, so, I copy my boot loader entry with

sudo cp /boot/loader/entries/XXX.conf /boot/loader/entries/linux-lts.conf

XXX.conf is my only boot in that folder, so I copied it and changed it:

/vmlinuz-linux -> /vmlinuz-linux-lts
...
initrd /initramfs-linux.img -> /initramfs-linux-lts.img

I checked the list of boot entries with:

sudo bootctl list

I changed the default kernel with:

sudo bootctl set-default linux-lts.conf

reeboted my machine and I rebuild and installed this package again, my camera works after that!

thank you for making this package!!

PD. please add support for new kernel 6.1.

Thanks for making it work on 5.18
