Original AVB driver for BBB from https://github.com/NiklasWan/linux/tree/dev_avb_5.4-rt . Documentation in https://niklaswan.github.io/GSoC-Overview/avb-alsa/ .
Redesigned for Out-of-tree compilation.
A word of warning: At this point the module is in an experimental alpha stage! It will most probably not work as expected, especially it cannot be used in any production environment.
A build infrastructure and kernel headers are needed:
sudo apt install build-essential linux-headers
The module should (at least) work with kernel versions 5.0 to 6.1.
For compilation on the native system just run make.
Providing a specific kernel version (will be used to access /lib/modules/$KVERSION)
make KVERSION=5.10.0-23-amd64
The module can be installed with sudo make install.
Afterwards, the module can be loaded with
sudo modprobe snd-avb.
if an ethernet interface other than eth0 should be used, it can be specified on the command line:
sudo modprobe snd-avb avb_ifname=enp7s0
Removing the module is performed with
sudo modprobe -r snd-avb.
If this is not possible ("modprobe: FATAL: Module snd_avb is in use"), removal can be forced with
sudo rmmod -f snd-avb.
The kernel log with debug messages can be watched live with sudo dmesg -w.
