Linux Kernel

Linus Torvalds announced the release of Linux Kernel 5.12 last night. He wrote on lkml:

Thanks to everybody who made last week very calm indeed, which just makes me feel much happier about the final 5.12 release.

New Features in Kernel 5.12 include:

  • Intel VRR / Adaptive-Sync for Intel Xe.
  • Radeon RX 6800/6900 series OverDrive overclocking support.
  • Mainline support for the Nintendo 64
  • Sony PlayStation 5 DualSense controller driver.
  • CXL 2.0 Type-3 memory device support
  • Lenovo Laptop Platform Profile support.
  • Better Microsoft Surface device support.
  • And much more.

How to Install Linux Kernel 5.12:

The Ubuntu Mainline Kernel Archive provides the new kernel packages via DEB files.

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

For those prefer using a graphical tool, see this tool to install the latest Kernel.

To manually download the mainline kernel packages for Linux 5.12, go to the link button:

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

  1. linux-headers-5.12.0-xxxxxx_all.deb
  2. linux-headers-5.12.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  3. linux-modules-5.12.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  4. linux-image-xxx-5.12.0-xxx-generic(/lowlatency)_xxx_amd64.deb

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

cd /tmp/

Linux Kernel 5.11 was released a day ago on Valentine’s Day. Here’ how you can install it in Ubuntu and Linux Mint based systems.

Linus Torvalds announced the Kernel 5.11: “Nothing unexpected or particularly scary happened this week, so here we are – with 5.11 tagged and pushed out.
In fact, it’s a smaller-than-average set of commits from rc7 to final, which makes me happy. And I already have several pull requests lined up for tomorrow, so we’re all set for the merge window to start.
.”

New features in Linux Kernel 5.11 include:

  • Intel Integer Scaling support
  • Intel async page flipping support
  • Initial support for AMD Green Sardine and Van Gogh APUs

Linus Torvalds announced the release of Kernel 5.10: “Ok, here it is – 5.10 is tagged and pushed out. I pretty much always wish that the last week was even calmer than it was, and that’s true here too. There’s a fair amount of fixes in here, including a few last-minute reverts for things that didn’t get fixed, but nothing makes me go “we need another week”. Things look fairly normal.

Kernel 5.10 features include:

  • New hardware support including Intel Rocket Lake and Alder Lake
  • AMD Zen 3 temperature monitoring support.
  • Raspberry Pi VC4 support
  • The Creative Labs SoundBlaster AE-7 sound card support.
  • Nintendo Switch controller support

Linux Kernel 5.9 was released a day ago. Linus Torvalds announced that:

Ok, so I’ll be honest – I had hoped for quite a bit fewer changes this last week, but at the same time there doesn’t really seem to be anything particularly scary in here. It’s just more commits and more lines changed than I would have wished for.

The bulk of this is the networking fixes that I already mentioned as being pending in the rc8 release notes last weekend. In fact, about half the patch (and probably more of the number of commits) is from the networking stuff (both drivers and elsewhere).

Linux 5.9 features initial Intel Rocket Lake graphics, NVMe zoned namespaces (ZNS) support, 32-bit x86 Clang build support, initial support for Radeon RX 6000 “RDNA 2” graphics cards, and more.

How to Install Linux Kernel 5.9 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.

For a graphical tool to install updated kernel package, try Mainline.

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.

How to Install Linux Kernel 5.5 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 5.5 are available for download at the link below:
