Parametrize the build with kernel version and rt patch version

remusmp commented 2 years ago

Arguments:

Kernel version (e.g. KERNEL_VERSION=5.10). If argument is missing then default to latest.
RT patch version (e.g. RT_PATCH_VERSION=rt54). If argument is missing then default to latest.

Current file is broken because of this: patch-5.10.73-rt54.patch.gz -> patch-5.10.78-rt55.patch.gz

Thanks for the contributions! Much appreciated!

One more thing needs to be done, i.e. update the .config file with the right settings. One cannot use a .config file from an older version with a newer version. I tried that a few weeks ago and the kernel, although it built, was not fully preempt - I had to regenerate the .config file. So my proposal here is to:

remove .config from this repo and don't add it to the docker image anymore
Dockerfile: use sed to disable KVM in .config
Dockerfile: use sed to enable the RT PATCH

I've just pushed the following work on this:

download latest RT patch for a given linux kernel version - it shouldn't break the build anymore when new rt patches are released
download latest raspbian as well by default

TO DO:

let the user specify a certain RT patch and a certain raspbian version (check the PR)
