If you see an error message in the Gentoo Kernel Guide on your PC, check out these fix ideas. gentoo-sources is a kernel based on Linux #4.x and 5.x with minor fixes to fix security issues, read the kernel and improve compatibility with one of our most unusual system architectures. The sys-kernel/gentoo-sources package contains most of the Gentoo Core Team websites.
Kernel is the basis of the operating system. Each of our kernels primarily contains device readers and provides interfaces for programs to access system hardware such as memory, visible cards, and block devices.
This short article is for the Linux kernel only and focuses on the methods you can find to obtain, configure, and compile the Linux kernel on Gentoo systems.
Which Kernel To Manually Install?
If you are using kernel sources or using genkernel, you can automate part of the process. Gentoo recommends the sys-kernel/gentoo-sources package for more users. Its stable releases use the Long-Term Stable (LTS) kernels from Upstream-Kernel.org.
Kernels of the distribution
The kernel company provides packages for installing and maintaining kernels through Portage. In any case, these kernels are compiled (if necessary) and appear with a single command, like almost all other packages, thus reducing administrative overhead. UpdatedKernel changes are performed when the system is updated (i.e. ends with -av world). The only step you need to take is to force all bootloaders to use the new kernel.
These kernels come with a default configuration that should “work” for most systems. For users who are not interested in customizing their precious custom kernel from scratch, these popcorn kernels can speed things up. sys-kernel/gentoo-kernel
The package contains the latest kernel that will be compiled and installed when the package conditions are met. It comes with a default layout that should work out of the box on most systems, but can help with customization if needed. sys-kernel/gentoo-kernel-bin
This may be a binary package containing the latest pre-compiled kernel to speed up installation. This element is a precompiled version of the gentoo-kernel package with evasion configuration.
Because gentoo-kernel* usually offers automatic configuration and compilationAs opposed to the usual manual way of compiling and installing popcorn kernels, the remainder of this article will walk you through installation using sys-kernels /gentoo – package sources. For more information about flags, see the main distribution project
Where is Gentoo kernel config?
The configuration file is located here in /usr/src/linux/. config This is a quick and therefore safe way to update an awesome config file that has all the build options you need to back up your hardware as well as bug fixes and security fixes.
To the kernels of the distribution
USAGE To Get A Single Kernel, You Must Include The Source Code For The Kernel. Gentoo Recommends Kernel Sources For The Computer System, Of Course Sys-kernel/gentoo-sources. They Are Maintained By The Creators Of Gentoo And Patched As Necessary To Address Security Vulnerabilities, Functional Issues, And Ideally Compatibility With Certain System Architectures.
Although all the reliable kernels provided by Gentoo are sourced from sys-kernel/gentoo, there are currently many other kernel packages that use the portage tree. See the kernel source overview article for aspects of most of them.
For more information on the choice, see the blog article on the site What is a stable kernel ?should be used? Greg Kroah-Hartman, renowned kernel developer.

- Auto Tuning
- genkernel is simply a tool used to automate the ni initramfs kernel build process. The purpose of genkernel is almost certainly to help users with certain kernel build processes.
- Manual tuning
- Manual configuration allows a specific user to create a custom kernel configuration with some effort.

- Basic Seeds
- Like the answer above, Kernels Seeds helps people, some with difficulty, create a huge custom kernel configuration that uses a free .config file as a base.

Native Kernel Support
How do I change my Gentoo kernel?
Step 1: Create new kernel sources.Step 2: Install the correct symlink to the new kernel.Step 3: Move relative to the new kernel folder.Step 4: Set up the file.Step 5: Build the kernel and initramfs.Step 6: Update the bootloader.
Kernel Command Line Options
When booting from the bootloader, the Linux kernel can accept command-line options to adjust its behavior. This can help move the debug kernel for a while on startup, blacklist a certain module that won’t load, etc.
Kernel.org contains a well-formatted list of purchasable kernel command-line options for reference.
In particular, it can be useful to save options on the command line even when starting Gentoo:
