I know this blog article. But the article uses Vanilla kernels and also needs 6 steps. With additional patches (4 steps), third-party modules (2 steps) and cleanup (1 step) the article would also need 13 steps:

Out of the box thinking: Send the patch upstream: - no steps required Open a bug for the kernel team with the patch and ask for inclusin: - 1 step Otherwise ...

Compiling the Linux Kernel, the SUSE way

https://www.suse.com/communities/blog/compiling-de-linux-kernel-suse-way/

This is my Kernel configuration, compilation and installation path:

1. Update kernel-source and kernel-default from Kernel_stable repository 2. Save kernel-source: cp -a /usr/src/linux-4.x.y-... /usr/src/linux-4.x.y-my 3. Apply my patches cd /usr/src/linux-4.x.y-my patch -b -p1 < ~myuser/.../my-kernel-patch.patch 4. Copy standard configuration: cd /usr/src/linux-4.x.y-my cp -v /boot/config-4.11.4-1.gcba98ee-default .config 5. Edit .config: remove CONFIG_LOCALVERSION, CONFIG_DEBUG_KERNEL, CONFIG_EXPERT remove some hardware-dependent settings 6. edit configuration interactively: Disable CONFIG_EXPERT and CONFIG_DEBUG_KERNEL, because otherwise "make binrpm-pkg" creates huge kernel binaries.

4..6 Instead, "make cloneconfig". -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)

OBS, and if it's just for your own machine, include the dkms steps in the spec file. Keep the package locally. -- Gertjan Lettink, a.k.a.

You will need to run 1. mkinitrd 2. grub2-mkconfig -o /boot/grub2/grub.cfg to make the kernel bootable after installing the rpm.

Just after installing rpms, dracut do it automatically, don't it? Regards. --- ┏━━┓彡 Masaru Nomiya mail-to: nomiya @ galaxy.dti.ne.jp ┃＼／彡 ┗━━┛ "Bill! You married with Computer. Not with Me!" "No..., with money."
