linux kernel is the essential part of any Linux operating system. It is responsible for resource allocation, low-level hardware interfaces, security, simple communications, basic file system management, and more. Written from scratch by Linus Torvalds (with help from various developers), Linux is a clone of the UNIX operating system. It is geared towards POSIX and Single UNIX Specification compliances.
As you might know already, Linux kernel 4.8 launched on October 2, as announced by Linus Torvalds himself, and it brought quite some interesting changes, including AMDGPU OverDrive support, Nvidia Pascal support, AMDGPU PowerPlay improvements, support for Raspberry Pi 3’s Broadcom BCM2837 system-on-chip (SoC), as well as support for Microsoft Surface 3 touch controller.
As with any new kernel branch, the first one is always marked as mainline, which means that it’s not yet ready to be deployed in stable GNU/Linux distributions, but only in those that are currently in development, such as Ubuntu 16.10 (Yakkety Yak). The status of the new kernel series changes to stable as soon as the first point release is out. Therefore, Linux kernel 4.8.1 is now stable enough to be used by any Linux-based OS.
“I’m announcing the release of the 4.8.1 kernel. All users of the 4.8 kernel series must upgrade,” says Greg Kroah-Hartman. “The updated 4.8.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.8.y and can be browsed at the normal kernel.org git web browser: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary.”
Includes powerful features
Linux provides users with powerful features, such as true multitasking, multistack networking, shared copy-on-write executables, shared libraries, demand loading, virtual memory, and proper memory management.
Initially designed only for 386/486-based computers, now Linux supports a wide range of architectures, including 64-bit (IA64, AMD64), ARM, ARM64, DEC Alpha, MIPS, SUN Sparc, PowerPC, as well as Amiga and Atari machines.
