Linux Kernel 4.11 Fearless Coyote Released – Features of Fearless Coyote Explained

Here we are going to tell you about the newly released kernel developed by Linus Torvalds. The new version of Linux i.e. Linux kernel 4.11 is named as Fearless Coyote. This eight release has come with so many new features in it. The new kernel has so many features in it i.e. Turbo Max 3.0 improvements, new perf ftrace tool, etc. You can read for all of them , so please be with us.

Linux Kernel 4.11 | Fearless Coyote

The release date for Linux kernel 4.11 was on 21st April 2017, due to some reason it was postponed to 30th April 2017. The kernel 4.11 is finally released by Mr. Linus Torvalds with a happy note on his website blog.

Linux 4.10-rc6 Released Code Name Fearless Coyote

Linux kernel 4.11 is a blend of many different things. A large variety of code section is covered by networking & sound drivers. The remaining code is focused on Arch updates, generic networking, and file system fixes. According to Linus Torvalds “The code section for Arch updates & generic networking is so small that he saw it on the last week of release date.”

So here for all the Linux users , we are going to describe the main features of Linux Kernel 4.11 & the changes that were made comparing the previous version.
Soon there will be linux distros released which are based on Fearless coyote. Before all the details are written here , you can check the new features of your post so that you can know what you are going to get after this version is implemented in the Linux Distros.

Features of Linux Kernel 4.11 / Fearless Coyote

Graphics changes

The power management for AMD graphics unit has been matured with new Kernel 4.11. The improved speed can also be seen in RADV Vulkan. With Intel DRM driver now you can easily handle DisplayPost & MST Audio. By default frame buffer compression is enabled for Skylake & other new hardware by default. TinyDRM is also merged with it.

Initial Gemini Lake support

The initial support for Gemini Lake chips is also added into it.

Scalable swapping for solid state drives

Modern storage devices are using Swap techniques not just to tackle memory load, but also helpful for performance improvement. Now the cloud storage SSD are also using it for more better performance as in case of traditional rotating hard disks. With kernel 4.11 the swap implementation more scalable make it suitable for modern storage devices.

SMC-R protocol

The implementation of SMC-R protocol defined in RFC7609 is supported by Kernel 4.11. If you don’t know about SMC-R protocol then read this. SMC-R stands for Shared Memory Communications-RDMA which is invented by IBM which lets the Virtual Machine to share memory & fasten communications.

Improved support for Intel Turbo Boost Max 3.0

Intel Turbo Boost 3.0 was one of the feature which Kernel was lacking . With the support provided for Intel Turbo Boost 3.0, users can make use of their CPU cores more efficiently.

Pluggable IO schedulers

In Linux 3.13, the block layer added a new multi-queue design which improved performance with modern devices like SSD, NVM. But there was no support for pluggable IO schedulers.
With kernel 4.11 release , a port of deadline scheduler has been added. In future more schedulers will be added in the newer versions.

New perf ftrace tool

perf ftrace is a new tool added in the perf toolkit. This is a simple perf ftrace front end for the existing interface. It now supports only two tracers i.e.  function_graph , function.

Support for OPAL drives

OPAL drives is a set of specification for data storage devices like disk drives to enhance security.  For example if an unauthorised person get the drive some how But could not see the data because of encryption. It is a specification of self-encrypting drives.

    Wow, so the lack of a simple PI call determined the game. The old refs are bad, but this has become a circus.
