Hi,

I a novice & want to contribute to linux community. I have basic knowledge of kernel.

Problem statement:
I want to work on x86 architecture. I am not sure how to go about unit testing. I can use qemu for testing but i find kernel on x86 architecture too big to compile. How i can get the smaller size kernel on x86 architecture? Please help me setting up testing environment so that i can test my changes properly & quickly.

thanks,
Shubham

If you want smaller kernel size, just avoid compiling modules or kernel component that you don't need. Things like unneccessary device support, protocol support are something you can begin with.

Also, once you do:

make

then if later you did modification on certain .c files, then next invocation of "make" will only recompile the changed .c files. if you need further speed, use ccache.
