There ia a comment from the packager of one of the AUR’s packages:
This package is obsolete!
Linux kernel 6.10 onwards now has built-in IPU6 drivers and this package will no longer work! Uninstall it from your system if it is still installed.
So if it is already in the kernel… 
find /lib/modules/$(uname -r) -type f -name '*.ko*' | grep ipu6
What is the output?
