Try asking on discord, I don't have any experience with drivers.

Basically everything is the same if you were writing them in C.

Wrong repo? :)

Why? :)

I understand that everything is the same as if you were writing in C. But you can't program kernel modules in regular C, because of the C standard library, which assumes there is a kernel thus they can call syscalls; in a kernel module, the module "is" the kernel (actually part of it), so it can't use the kernel userspace API because it's inside.
This being said, what is necessary for V to work is to avoid using the glibc, but using a subset of functionalities instead (as C is already limited for kernel dev in terms of library). Writing a kernel module in C also requires a set of command line flags for both the compiler and the linker.

So, there could be a command line switch in the V compiler such as "-kernel" that would: 1) add the command line flags to the C compiler and linker so it generates a .ko; 2) restrict the language if there are features that cannot be used in kernel mode (I didn't see any yet); 3) use an alternative library implementation that doesn't invoke syscalls.
