Linux Kernel 5.11 – What’s New

Processors

AMD Zen1/Zen2/Zen3 PowerCap RAPL (Runtime Average Power Limiting) Support is added. The power capping feature was there for Intel hardware which is now being added for AMD Zen initial series of processors.

AMD SFH Driver (Sensor Fusion Hub) driver is being included in this Kernel. This driver handles the gyroscope and other sensors in AMD based Ryzen series of laptops.

AMD SoC PMC (system-on-chip power management controller) driver is included which brings better power management on Ryzen notebooks, AMD Chromebooks.

Software Guard Extensions support for Intel processors finally lands. This brings better security on DRM, web browsing and encryption keys handling, etc cases.

Intel Platform Monitoring Technology (PMT) is now supported by this Kernel. This feature helps to collect telemetry about devices and managing them. This is beneficial for large organizations and data centers that handle huge sets of devices.

Linux Kernel 5.11 release – Download and Install

You can install the mainline kernel packages from the below link right now in your latest Ubuntu or Ubuntu-based derivatives. But it is not recommended to install this as it might break the current Ubuntu Linux system whichever you are running (e.g Ubuntu 20.04 LTS). If you are running Debian, Ubuntu, and other stable releases – do not upgrade using the below steps. Instead, wait for an official update in respective distributions.

For general users, unless you are keen to experiment with the latest hardware whose support is added in this release, you should not update at the moment.

If you still want to install the latest Linux Kernel 5.11, follow the below instructions to install in Ubuntu-based systems.

  • Visit the mainline kernel page.
  • There are two types of builds available – generic and lowlatency. For common systems, you can download generic builds that work most of the time. For audio recordings and other setups that require low latency, download the lowlatency one.
  • Download below four packages for generic via terminal and install.
cd /tmp
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11/amd64/linux-headers-5.11.0-051100-generic_5.11.0-051100.202102142330_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11/amd64/linux-headers-5.11.0-051100_5.11.0-051100.202102142330_all.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11/amd64/linux-image-unsigned-5.11.0-051100-generic_5.11.0-051100.202102142330_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11/amd64/linux-modules-5.11.0-051100-generic_5.11.0-051100.202102142330_amd64.deb
sudo dpkg -i *.deb
  • After installation, reboot the system.

The instruction for lowlatency and other architecture (ARM) installations are the same. Replace the package name in above wget command. Below are the links to .deb files for other architectures.

If you are using Arch Linux, or Arch-based distribution, it is expected that Linux Kernel 5.11 release packages arrive within the March 2021 first week during monthly refresh.

Linux Kernel 5.11 would be available in Fedora 34 and Ubuntu 21.04 Hirsute Hippo. Linux Kernel 5.12 development window kicks off with this stable release.
