Compiling a driver into the kernel

#GNU #Linux #Tutorial #Driver #DriverDevelopment #embedded_systems #bathroom
Sorry for the bad audio quality. I accidentally got the wrong microphone setting. :-/
But the video is informative anyhow. I compiled lots of Linux Kernel Modules and Drivers on this channel. But I always compiled them to kernel objects, which needs to be loaded into the Kernel. In this video, I will show you how you an directly compile a driver or kernel module into the kernel. Enjoy!

Nice video as usual , i suggest to you to make an playlist about void linux and the tools that you used and vim , that will be interesting ❤

You are doing very good job. i like your videos

Excellent video, as usual. Thanks!
Sound like from a barrel. Perhaps, some kind of echo effect is turned on.

Thanks for sharing the content, it really helped.
I do have a question though, if in case I need to load my firmware as a kernel module, is it the same steps that need to be followed? I mean like do need to place them as part of driver's folder or is there any other right place to include?

[@johannes4gnu_linux96]

You are welcome. Basically yes, but instead of choosing "*" in makeconfig, select "M". so, in the config you would see CONFIG="M" instead of "y". When you compile the kernel the module will know be build as a standalone kernel module. In my example you will get answer.ko file.

Good job 👏

Nice Brother thanks

I know you might be a linux purist, but do you know how to do this for the WSL kernel? Trying to add a driver for a wireless adapter. Not sure if I should build it into the kernel or make it a module. Not sure if WSL2 supports the latter.

[@johannes4gnu_linux96]

Well, it depends. If you just want to corss-compile a driver for a remote target, WSL should be fine. So, if you want to add this wireless adapter to an embedded system for example, WSL is ok.
But if you want to write a driver so you can use the wireless adapter in WSL, I would say, no, that is not possible. The problem is that WSL does not really touch your hardware. For the interfaces, e.g. Ethernet adapters, I think it is using a WSL-bridge instead, and at the end you will use the windows driver.
So, if you want to write a wireless adapter driver use a VM, dual boot or install Linux on a separate device. 😉

Nice video but the mic audio sounds again weird ;-)

[@johannes4gnu_linux96]

Thanks. Yeah, I know and will try to do better next time :)
