The best modified Linux kernels

The Linux kernel is the main part of the Linux operating system that manages the computer's shared resources, provides access to the file system, manages processes, and communicates with the computer's hardware.

Kernel tasks

The main tasks of the Linux kernel are:

1. Memory management - allocating and controlling memory access.
2. Process management - managing and controlling the execution of processes on the computer.
3. File system management - providing access to the file system and managing files.
4. Device management - managing the computer's hardware, including input and output devices, network cards, and other devices.

The Linux kernel is open source, which means that anyone can learn and modify it. The Linux kernel is developed and maintained by a community of developers around the world, as well as by companies such as Red Hat, IBM, Intel, Oracle, and others. This allows the Linux kernel to be improved and enhanced with each new version.

What is a modified kernel

A modified Linux kernel (modified Linux kernel) is a Linux kernel that has been modified, adding new features, fixing bugs, changing performance or device behavior.

Typically, modified kernels are created to improve performance, optimize performance with a specific type of hardware, add new features, or increase resistance to hacking and malware.

Specific modifications may include security patches, driver updates, task scheduler settings, network stack optimization, and other improvements.

List of modified kernels

1. The pf-kernel is a Linux kernel that is optimized for network security and traffic management. It includes patches that provide more secure data transfer as well as better network traffic management.
2. XanMod is a Linux kernel that is optimized for maximum performance and low latency on the system. It includes patches that improve network drivers and file systems, as well as prioritization and latency adjustments to improve performance.
3. Kernel-rt (Real-Time Kernel) - Designed for real-time, that is, for systems where the absence of latency is critical. It includes patches that improve timer accuracy and reduce system latency.
4. Grsecurity is a set of security patches that can be applied to the Linux kernel. It includes various tamper-proof mechanisms such as stack protection, execution control, buffer overflow protection, and other techniques.
5. Zen-kernel - The Linux kernel is optimized for performance and responsiveness in response to user requests. It includes patches that improve task scheduling mechanisms, increase the speed of network packet processing, and reduce system latency.
6. Linux-Libre is completely free of any proprietary code and drivers. It is designed for users who seek to use only free (no ties to specific owners) software. It includes only free drivers and forgoes any proprietary software.

Typically, a modified Linux kernel is available for download and installation on compatible systems. Using a modified kernel can be risky, as it can become unstable on systems that have not been tested for compatibility.
