[How To] Upgrade to Linux Kernel 4.0 RC6 on Ubuntu and Linux Mint


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.



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.


What's new in Linux Kernel 4.0 RC6:

  • Things are calming down nicelly, and there are fixes all over. The NUMA balancing performance regression is fixed, and things are looking up again in general. There were a number of i915 issues and a KVM double-fault thing that meant that for a while there I was pretty sure that this would be a release that will go to rc8, but that may be
  • unnecessary. Apart from the aforementioned issues, the bulk of this is mostly small misc driver fixes and architecture updates. The shortlog gives more of a flavor of what's been going on.
