Hi all, I have been trying debian kernel on my OMAP5432 uEVM devboard these days and now manage to boot it by adding some extra configs in the kernel and configure initramfs-tools to include some .ko of regulator drivers in the initrd. Here, I have a few questions about how to do it (adding new configs to support new platform) in debian( kernel)’s way. The first question is about the recommended procedure to change configurations while building the kernel package for testing. According to the debian linux kernel handbook, the recommended ways should be like: $ make -C debian/build/build_armhf_none_armmp-lpae menuconfig And then: $ fakeroot make -f debian/rules.gen binary-arch_armhf_none_armmp-lpae However, I found that it (menuconfig) doesn’t actually affect the real configs while doing binary-arch packaging (though it does change debian/build/build_armhf_none_armmp-lpae/.config). What I have done (while testing) was adding the required configs to the end of debian/build/config.armhf_none_armmp-lpae (for temporary packaging test). The second question is about adding missing .ko while making initrd. Right now, in order to include necessary regulator drivers (palmas-regulator.ko etc.) in the initrd, I have to manually add the required modules in /etc/initramfs-tools/modules. Is it necessary to look into initramfs-tools and make a patch to include the required .ko by default? Or there are other preferred ways to solve the problem if the OMAP5432 uEVM can be called supported by Debian. Cheers, Chen Baozi
