Rtl8812au: It is possible to compile against a moduleless kernel?

[iagosrodrigues]

Hi, I'm actually running a kernel with all modules compiled as builtin, so my question is:

It's possible to compile with the modules=n in .config?

[TheSeven]

Yes, it is possible, but might need some minor makefile fixes.
Basically put the git repository into drivers/net/wireless/rtl8812au and edit Kconfig and Makefile in the parent directory to include it.
There is some confusion around RTL8812A vs. RTL8821A config options that might need addressing...

Yes it's possible, but that's a lot of work.. have to rip out the firmware blob and everything..I mean.. it's a LOT of work. still interested? I can point you in the right direction, but it requires some understanding for the language "C" .. let me know

I actually did it successfully on my similarly patched up rtl8812bu driver over here:
https://github.com/TheSeven/rtl88x2bu
It's mashed up with a lot of other changes in the latest commit there, but might still provide some hints

I see your using code from this repo :yum:
