[opensuse-kernel] [RFC] dtb-*: Generate the filelists during build
This allows us to share the mkspec-dtb script among slightly different
branches. Nonexistent dtbs will result in empty RPM packages.

I may be missing something but wouldn't ${dts%%*.dts} expand to empty string whenever $dts ends with ".dts"? Is this what we wan't here? Michal Kubeček -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

The % removes the shortest matching pattern, so this correctly removes the .dts suffix. But I agree that it is extremely confusing, I will remove the redundant '*'.

One '%' does (so that ${dts%*.dts} is indeed equivalent to ${dts%.dts}). But Andreas suggested to replace it with '%%' which would cut off the longest match - and that would be the whole string whenever it ends with ".dts".

And that is precisely why I called it extremely confusing: The double % is there because of the rpm specfile parser, bash gets a single %. Oh, and for the real connoisseurs, we also have a quadruple % in rpm/kernel-binary.spec.in ;). Anyway, we drifted away from the topic a bit. I posted the RFC to ask if it is an acceptable trade off to have a shared mkspec-dtb script at the cost of occasionally having empty dtb-* packages.

Could you give us a verbose explanation of what the RFC is doing? For arm64 I would be fine with an auto-generated list of sub-packages: Every vendor directory arch/arm64/boot/dts/foo/ should get its own dtb-foo subpackage. That requires access to an expanded source tree, which I miss in mkspec-dtb. Lua script in the .spec might be a solution? For ARMv7 and ARMv6 things are more complicated, so I don't see how we could automate them... Even the soc-board.dts convention has exceptions.

It generates the %files sections for subpackages during rpm build, as opposed to the mkspec-dtb script generating them. So the mkspec-dtb can live in the packaging branch and contain the union of all the dtb subpackage definitions from master, linux-next, vanilla, SLE15 and the spec file will produce empty subpackages if the kernel does not have a given dts file.
For arm64 I would be fine with an auto-generated list of sub-packages: Every vendor directory arch/arm64/boot/dts/foo/ should get its own dtb-foo subpackage. That requires access to an expanded source tree, which I miss in mkspec-dtb. Lua script in the .spec might be a solution?
This sounds interesting, but the RFC patch is not doing this. And I'm afraid not even lua will help, because the spec file is parsed and all macros evaluated before any of the build scriptlets is executed. We would have to unpack the linux tarball and apply all patches inside the lua script.

% is an rpm special character. To insert a literal % in a specfile you need to double it. You should not depend on rpm leaving it alone when followed by a random character.
