Sound on the RockPro64

I have never included a patch, so I am not sure what to do exactly. Does this mean I have to recompile the kernel? So if I come from the readme here,

github.com

drm-subtree/README.md at 15-CURRENT · jsm222/drm-subtree

what steps do I need before I even get to the first point here?

make buildenv TARGET_ARCH=aarch64 BUILDENV_SHELL=/bin/sh

Also guessing from the URL above, I assume I would need to install a amd64 15-current version first on that laptop and not 15.1-RELEASE?

You do not need that command. You are compiling on AMD64 correct?

Look at adding new module to FreeBSD Kernel. Basically copy the C file to new directory under /usr/src/sys/dev/*
Then add details that a new module is present in sys/dev and make a new kernel.

The name of the patch should help you place it.

sys_dev_iicbus_es8316.c = new file /usr/src/sys/dev/iicbus/es8316.c

Then you must add the module name to config or manually compile the module.

For a caveman like me I just cut and paste the text and delete all the plus signs. Figuring out diff/patch sometimes takes me longer.
