Emerging the new kernel sources

root #emerge --ask --update --deep --with-bdeps=y --newuse @world
# replace gentoo-sources with whatever version of the kernel that is in-use??
root #emerge --ask --update --deep --with-bdeps=y --newuse sys-kernel/gentoo-sources
# ls /usr/src
linux-6.1.53-gentoo-r1

Set symlink to new kernel sources

The kernel configuration is saved in a file named .config in the directory that holds the kernel sources, a symlink is used to point to that directory.

The symlink /usr/src/linux should always point to the directory that holds the sources of the kernel which currently runs. This can be done in one of three ways:

Default: Setting the link with eselect.
Alternative 1: Manually updating the symbolic link. ln sf linux-6.1.53-gentoo-r1 linux in /usr/src
Alternative 2: Installing the kernel sources with USE="symlink". ??? How ???
eselect kernel list

# eselect kernel list    <-- list available
Available kernel symlink targets:
  [1]   linux-6.1.53-gentoo-r1
# eselect kernel set 1
# eselect kernel list
Available kernel symlink targets:
  [1]   linux-6.1.53-gentoo-r1 *     <-- * indicate the the chosen sources. 
(chroot) hc4Gentoo /usr/src # ls -l
total 4
lrwxrwxrwx  1 root root   22 Oct  4 00:11 linux -> linux-6.1.53-gentoo-r1   <-- `eselect kernel set 1` will create this link
drwxr-xr-x 27 root root 4096 Oct  3 23:59 linux-6.1.53-gentoo-r1

Moving to the new kernel folder

Now that the symbolic link has been modified, change the working directory to the new kernel folder. $cd /usr/src/linux.

Copy the previous kernel configuration

(chroot) hc4Gentoo /usr/src/linux # ls -a
.   .clang-format  .get_maintainer.ignore  .gitignore  .rustfmt.toml  CREDITS        Kbuild   LICENSES     Makefile  arch   certs   distro   fs       init      ipc     lib  net   samples  security  tools  virt
..  .cocciconfig   .gitattributes          .mailmap    COPYING        Documentation  Kconfig  MAINTAINERS  README    block  crypto  drivers  include  io_uring  kernel  mm   rust  scripts  sound     usr
(chroot) hc4Gentoo /usr/src/linux # zcat /proc/config.gz > .config

The .config from the old kernel can be converted to be used with the new kernel. The conversion can be done several ways including running either make oldconfig or make olddefconfig.

make oldconfig, will prompt you for the new selection make olddefconfig, will keep all of the options from the old .config and set the new options to their recommended (i.e. default) values:

- Observing the difference
    - A diff tool can be used to compare the old and new .config files to see what options have been added:
