[Buildroot] How to apply RT kernel patches?

[Buildroot] How to apply RT kernel patches?

[Patrick Doyle]

How do folks tend to apply the RT kernel patches using buildroot?

There are patch sets available at
https://cdn.kernel.org/pub/linux/kernel/projects/rt/4.9/.  I could
download one of those, unpack it into my buildroot tree, and configure
that directory as a patch directory for the kernel.  But that is
problematic from a version control standpoint.  I would end up with
the whole set of (300+) patches in my source tree that will lead to
repository bloat.

I would rather convince the buildroot machinery to download and apply
the patches automatically as part of the build process.

Do others do this?

Do others do something else?

I think I'll just toss this question out there and see what I can learn.

Thank you.

Have you tried setting:
    BR2_LINUX_KERNEL_PATCH="https://cdn.kernel.org/pub/linux/kernel/projects/rt/4.9/patches-4.9.68-rt60.tar.xz"

As far as I remember, this is is supposed to work, because we do have
explicit support for handling (un)compressed tarballs of patches.

Yann E. MORIN.
