Thanks for your effort! gentoo-kernel is building without issue. It is certainly nice to be able to leverage binpkg! As discussed on IRC, gentoo-kernel populates an uncompressed vmlinux in /boot that needs to be wrapped as a uimage for uboot platforms. As suggested, I've been iterating on a trivial uimage kernel wrapping script in /etc/kernel/postinst.d. Feel free to peek at the current postinst.d script here: https://github.com/lmchale/uImage-eselect/blob/main/90-uImage.install The kernel source provides a reliable ppc uimage wrapping script in: arch/powerpc/boot/wrapper (https://elixir.bootlin.com/linux/v5.10.88/source/arch/powerpc/boot/wrapper). However, this does not exist in the /usr/src/<kver> directory deployed by gentoo-kernel, but does exist in gentoo-sources. Depending on the platform, this script also may rely on object files generated in arch/powerpc/boot. Is it possible to preserve the arch/powerpc/boot directory? If not, the above postinst.d script is a workable solution. Followed up just in-case there is interest in generalizing the postinst.d uboot script. Thanks, will check out. Yes we can preserve more files if there’s real value ofc, I’ll look at it too, thanks for suggestion. |
I've been building and installing the kernel (via a script) from sys-kernel/gentoo-sources thus far for a somewhat odd embedded powerpc architecture. Installing isn't so bad, but it requires somewhat manual cleanup of /boot and /lib/modules from time to time. I would also like to be able to utilize the binpkg facilities of sys-kernel/gentoo-kernel, if possible. I've attached a few diffs in order to treat ppc like arm for easy kernel building on embedded ppc platforms. It would be great if this can be included going forward. I'm currently on kernel 5.10 as 5.11 introduced some issues with wifi card region issues on atheros cards in ap mode. I haven't re-tested since early 5.11 builds. I currently build a uImage from sys-kernel/gentoo-sources, but I may be able to boot a self-extracting vmlinux directly (not yet tested). Otherwise, I'll need to devise a yet to be written post-install ebuild command to convert a vmlinux to a uImage... If this already exists somewhere, please let me know!
