Hello,
I am new to kernel development, currently working on https://kernelnewbies.org/FirstKernelPatch. I reached the step "Install your changes" in "Modifying a driver on native Linux". I would like to separate my developed kernel and my installed kernel and to switch between the two in order to test my changes. I am not sure that my tutorial explains how to do that. If you have a link that proposes a workflow for this request (or if my tutorial does explain this workflow and I'm missing the exact paragraph that does that) please let me know.
I've found running a kernel under qemu with my normal rootfs to be quite useful to quickly try out things. See the qemu-test script in the RAUC project for an example: https://github.com/rauc/rauc/blob/master/qemu-test Don't forget to backup of course. Maybe you could even read-only mount the rootfs for added safety. Good luck, Ahmad
Thanks, Gidi
