Add Khadas VIM3 support #84

Closed agners closed 2 years ago

agners commented 3 years ago

Add sound configuration for Khadas VIM3. Currently only HDMI supported. This requires access to device tree in sysfs.

That will not work because it's mask by docker. We Can pass the machine type over env

Yes I realized, that is why I set it to draft :sweat_smile:

We could also enable device tree access for Audio with a Supervisor upgrade I guess? Add-ons have that as an option. Not sure what is better/easier.

Hm, I see there is currently not a easy way to access the firmware directory in its default location. /proc/device-tree symlinks to /sys/firmware/devicetree/base and /sys/firmware/` directory is in a hard-coded mask list since years: https://github.com/moby/moby/commit/8b1772c86b20d06ae6bd8ccf4b20f6df4cd86b62

We support non-native location with this pull request: https://github.com/home-assistant/supervisor/pull/519

It seems that a bind mount to a different location works, but the symlink /proc/device-tree can't be changed, so whereever we bind mount it would be non-standard :(

New version using sound device id from sysfs.
