Hello World device driver kernel compile

[hapster]

Hi. I'm starting out in writing device drivers. Let's say I have a simple source code named test.c and the latest linux kernel source code, where do I put test.c and where do I put the Makefile with the obj-m: test.o thing? Should I make a new folder named "tests" from the root directory?

Thanks in advance.

Is "test" a kernel module or is it going to be statically included in the kernel?

.ko file.

Nevermind. I got it already. I just need to compile it against a kernel tree regardless of its position. I ran it using make -C [kernel source] -M=`pwd` modules
