Debian and Ubuntu: Debian LTS, Debian 9.4, Zstd and More

  • Debian LTS work, February 2018

    I was assigned 15 hours of work by Freexian's Debian LTS initiative and worked 13 hours. I will carry over 2 hours to March.

    I made another release on the Linux 3.2 longterm stable branch (3.2.99) and started the review cycle for the next update (3.2.100). I rebased the Debian package onto 3.2.99 but didn't upload an update to Debian this month.

  • Debian 9.4 Stretch GNU/Linux Released With 150+ Fixes: Update Now

    One of the great things about using a popular Linux distro is that you keep getting timely upgrades, which ensure that you’re running a secure operating system. The same holds true for Debian GNU/Linux, whose development team keeps offering regular updates. Just a couple of days ago, the team pushed the fourth point release of Debian 9 “stretch.”

    For those who don’t know, Debian 9.0 series is an LTS edition, and it’ll remain supported for the next five years.

  • Debian GNU/Linux 9.4 "Stretch" Point Release Brings More Than 70 Security Fixes

    The Debian Project announced over the weekend the release of the fourth maintenance update to the stable Debian GNU/Linux 9 "Stretch" operating system series.

    Debian GNU/Linux 9.4 "Stretch" comes three months after the 9.3 point release and brings more than 70 security fixes and 89 miscellaneous bugfixes for various core components or other packages available in the main software repositories of the Linux-based operating system. However, the Debian Project warns that this point release doesn't represent a new version of Debian Stretch.

    "This point release mainly adds corrections for security issues, along with a few adjustments for serious problems. Security advisories have already been published separately and are referenced where available. Please note that the point release does not constitute a new version of Debian 9 but only updates some of the packages included," reads the release announcement.

  • Debian 9.4 released
  • Ubuntu Installs Made 10% Faster Using Facebook Tech

    If you long to install Ubuntu a little bit faster help it at hand thanks to some nifty open-source tech developed by Facebook.

    Using Zstandard (zstd), a ‘lossless data compression algorithm’ developed by Facebook, Ubuntu developers have been able to speed up Ubuntu installs by 10%.

    While Zstd is primarily designed for use in “real-time compression scenarios” it is able to unpack packages during an Ubuntu install faster than current compression tools Xz and Gzip do.

  • Canonical Working On Zstd-Compressed Debian Packages For Ubuntu

    Support for Zstd-compressed Debian packages was worked on last week by some Canonical/Ubuntu developers and already by the end of the year they are looking at potentially using it by default.

    Zstd is the compression algorithm out of Facebook that has been attracting a fair amount of interest in the Linux/open-source space due to its higher decompression speeds that can trump XZ or Gzip.

  • Keeping Governance Simple and Uncomplicated

    We did this in Ubuntu. We started with some core governance boards (the Community Council, focused on community policy and the Technical Council focused on technical policy). The rest of the extensive governance structure came as Ubuntu grew significantly. Our goal was always to keep things as lightweight as possible.

  • Ubuntu 18.04 LTS Beta 1 Released for Participating Flavors

    Ahoy, Beavers! The first beta builds of the Ubuntu 18.04 release cycle have been released and are available to download.

Graphics: VC4 and AMDVLK Driver

  • VC4 display, VC5 kernel submitted
    For VC5, I renamed the kernel driver to “v3d” and submitted it to the kernel. Daniel Vetter came back right away with a bunch of useful feedback, and next week I’m resolving that feedback and continuing to work on the GMP support. On the vc4 front, I did the investigation of the HDL to determine that the OLED matrix applies before the gamma tables, so we can expose it in the DRM for Android’s color correction. Stefan was also interested in reworking his fencing patches to use syncobjs, so hopefully we can merge those and get DRM HWC support in mainline soon. I also pushed Gustavo’s patch for using the new core DRM infrastructure for async cursor updates. This doesn’t simplify our code much yet, but Boris has a series he’s working on that gets rid of a lot of custom vc4 display code by switching more code over to the new async support.
  • V3D DRM Driver Revised As It Works To Get Into The Mainline Kernel
    Eric Anholt of Broadcom has sent out his revised patches for the "V3D" DRM driver, which up until last week was known as the VC5 DRM driver. As explained last week, the VC5 driver components are being renamed to V3D since it ends up supporting more than just VC5 with Broadcom VC6 hardware already being supported too. Eric is making preparations to get this VideoCore driver into the mainline Linux kernel and he will then also rename the VC5 Gallium3D driver to V3D Gallium3D.
  • AMDVLK Driver Gets Fixed For Rise of the Tomb Raider Using Application Profiles
    With last week's release of Rise of the Tomb Raider on Linux ported by Feral Interactive, when it came to Radeon GPU support for this Vulkan-only Linux game port the Mesa RADV driver was supported while the official AMDVLK driver would lead to GPU hangs. That's now been fixed. With the latest AMDVLK/XGL source code as of today, the GPU hang issue for Rise of the Tomb Raider should now be resolved.

AMD Ryzen 7 2700X Linux Performance Boosted By Updated BIOS/AGESA

With last week's initial launch-day Linux benchmarks of the Ryzen 5 2600X / Ryzen 7 2700X some found the Linux performance to be lower than Windows. While the root cause is undetermined, a BIOS/AGESA update does appear to help the Linux performance significantly at least with the motherboard where I've been doing most of my tests with the Ryzen 7 2700X. Here are the latest benchmark numbers. Read more

GNU: The GNU C Library 2.28 and Guix on Android

  • Glibc 2.28 Upstream Will Build/Run Cleanly On GNU Hurd
    While Linux distributions are still migrating to Glibc 2.27, in the two months since the release changes have continued building up for what will eventually become the GNU C Library 2.28. The Glibc 2.28 work queued thus far isn't nearly as exciting as all the performance optimizations and more introduced with Glibc 2.27, but it's a start. Most notable at this point for Glibc 2.28 is that it will now build and run cleanly on GNU/Hurd without requiring any out-of-tree patches. There has been a ton of Hurd-related commits to Glibc over the past month.
  • Guix on Android!
    Last year I thought to myself: since my phone is just a computer running an operating system called Android (or Replicant!), and that Android is based on a Linux kernel, it's just another foreign distribution I could install GNU Guix on, right? It turned out it was absolutely the case. Today I was reminded on IRC of my attempt last year at installing GNU Guix on my phone. Hence this blog post. I'll try to give you all the knowledge and commands required to install it on your own Android device.
  • GNU Guix Wrangled To Run On Android
    The GNU Guix transactional package manager can be made to run on Android smartphones/tablets, but not without lots of hoops to jump through first.
