Linux Kernel

Linus Torvalds announced the release of Linux kernel 5.8 two days ago on Sunday. Here’s how to install it in Ubuntu and / or Linux Mint.

New features in Linux Kernel 5.8 include:

  • Qualcomm Adreno 405 / 640 / 650 open-source support.
  • AMDGPU TMZ support.
  • Intel Tiger Lake SAGV support.
  • New Arm SoC and platform support.
  • AMD Energy Driver.
  • Initial support for booting POWER10 processors.
  • Intel Tiger Lake Thunderbolt support for Intel’s Gateway SoCs.
  • And many other new features and improvements.

How to Install Linux Kernel 5.8 in Ubuntu:

The mainline kernels do not include any Ubuntu-provided drivers or patches. They are not supported and are not appropriate for production use

The mainline kernel packages for Linux 5.8 (64-bit) are now available for download at the link below:

Download Kernel 5.8

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio):

  1. linux-headers-5.8.0-xxxxxx_all.deb
  2. linux-headers-5.8.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  3. linux-modules-5.8.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  4. linux-image-xxx-5.8.0-xxx-generic(/lowlatency)_xxx_amd64.deb

Alternatively you can download and install the kernel binaries via terminal commands ( open terminal via Ctrl+Alt+T):

Linux Kernel 5.6 was officially released. Linus Torvalds announced:

So I’ll admit to vacillating between doing this 5.6 release and doing another -rc.

This has a bit more changes than I’d like, but they are mostly from davem’s networking fixes pulls, and David feels comfy with them. And I looked over the diff, and none of it looks scary. It’s just slightly more than I’d have preferred at this stage – not doesn’t really seem worth delaying a release over.

So about half the diff from the final week is network driver fixlets, and some minor core networking fixes. Another 20% is tooling – mostly bpf and netfilter selftests (but also some perf work).

Linux Kernel 5.5 features WireGuard VPN support, and a lot of other notable improvements, including initial USB 4 support, Amazon’s Echo smart speaker, new Intel, AMD, and Arm hardware enablement.

Linux Kernel 5.5 was announced two days ago. Linus Torvalds wrote on lkml.org:

So this last week was pretty quiet, and while we had a late network update with some (mainly iwl wireless) network driver and netfilter module loading fixes, David didn’t think that warranted another -rc. And outside of that, it’s really been very quiet indeed – there’s a panfrost driver update too, but again it didn’t really seem to make sense to delay the final release by another week.

Kernel 5.5 release highlights:

  • Support for the Broadcom BCM2711 SoC (Raspberry Pi 4).
  • New Logitech driver for G15 and G510 keyboard.
  • KVM support for IBM POWER secure guests/VMs.
  • Initial Intel Jasper Lake support.
  • Intel 5-level paging support is enabled by default
  • AMD OverDrive overclocking for Navi GPUs.
  • and much more other changes.

Linux 5.4 Kernel was released today. Here’s how to install it in Ubuntu and Linux Mint.

Linus Torvalds announced the 5.4 Kernel on lkml.org:

Not a lot happened this last week, which is just how I like it. And as expected, most of the pull requests I got were for the 5.5 merge window, which I’ll obviously start working through tomorrow.

Linux 5.4 Kernel brings a lot of new hardware support,including AMD Arcturus GPU, Navi 12 and Navi 14 GPUs, AMD Dali and Renoir APU support,Intel Tiger Lake “Gen 12” graphics,Qualcomm Snapdragon 855 SoC, Intel Ice Lake Thunderbolt support.

The latest stable Linux Kernel 5.1 was released. Linus Torvalds announced last night:

So it’s a bit later in the day than I usually do this, just because I was waffling about the release. Partly because I got some small pull requests today, but mostly just because I wasn’t looking forward to the timing of this upcoming 5.2 merge window.

On the whole, 5.1 looks very normal with just over 13k commits (plus another 1k+ if you count merges). Which is pretty much our normal size these days. No way to boil that down to a sane shortlog, with work all over.

Linux 5.1 brings many exciting changes including improved support for Intel Fastbook (enabled by default), Intel 22260 WiFi support, new I/O interface, new ACPI support, Raspberry Pi 3 Model A+ support by mainline, and a lot of new hardware support.
