Building an Arch 5.0.19 kernel

Kernel 5.1 has been a real buggy for me so I'm sticking with the 5.0 series for now. I would like to build the current 5.0.19 which is not in the Arch repository. What's the best way to do that? I know how to build the kernel the traditional way but then I won't get a package that can be managed by pacman.

I know how to build using "asp update linux" etc but that only gets the latest 5.1 kernel, not what I want. Is there an easy way to pull the PKGBUILD and related files for the 5.0.13 Arch kernel then update that to 5.0.19?

Re: Building an Arch 5.0.19 kernel

There's an even easier way, just get the built package from the archive (assuming you don't still have it in your own cache).

EDIT: ooh, you want 5.0.19, yes that was never in the repos.  Still use asp, and just update the pkgver and _srcname to what you need.

I forgot to mention that I tried asp and updating the pkgver but it failed. I don't believe that 5.0.19 is in the Arch git source archive at all.

How did it fail?

There is no "Arch git source archive".  PKGBUILDs retrieve source files directly from upstream - in this case kernel.org.

Does it?

Re: Building an Arch 5.0.19 kernel

Arch does mirror upstream repos for some packages but that line isn't in the PKGBUILD I get from asp.  Where did you get that PKGBUILD?

EDIT: oops, asp seems to be giving me old PKGBUILDs for some reason (edit 2: I hadn't run `asp update`).  The current one does pull from the arch mirror repo.  In any case, you can change that to kernel.org sources.

Just "asp update linux" and "asp checkout linux". That's the PKGBUILD I just got.

That's the PKGBUILD used for 5.0.13-arch1 , the last 5.0.x kernel arch had.

The extra/linux changelog indicates several things were changed for the 5.1 kernel, starting with 5.0.13 seems a better choice.

Works, sweet, thanks! I was working on the same thing but couldn't get the kernel.org git to work right.
