does anyone have an example of a Go kernel module

[Siglo XIX]

I have tried many ways but now that the ecosystem is more mature maybe someone knows of an example of how to make a Linux kernle module with Go,.

Maybe you mean something like this ?

Hasn’t been touched in 6 years and it doesn’t work. I guess they figured out it wasn’t worth the effort. 

The only plausible way to write a kernel module in Go is… don’t.

Maybe run a user space Go process and some sort of shared memory communication.

Why would you want to do that? The amount of stuff going on under the hood in a Go program (GC, scheduling, etc)
make it a bad fit for low level kernel stuff. 

So best stick to C.
Writing a Kernel module in C is well supported and documented.
Having a skim through https://lwn.net/Kernel/LDD3/ .

Recently some people have been writing modules in Rust.
I have not tried it myself, but there is some documentation on the web, eg 
https://www.kernel.org/doc/html/latest/rust/quick-start.html

Or as others have suggested write your program as a plain old user-mode program in Go,
and write a minimal device driver which creates a sys-fs device tree that your program can talk to.
