  • Bootlin toolchains integration in Buildroot

    Since 2017, Bootlin is freely providing ready-to-use pre-built cross-compilation toolchains at We are now providing over 150 toolchains, for a wide range of CPU architectures, covering the glibc, uClibc-ng and musl C libraries, with up-to-date gcc, binutils, gdb and C library support.

    We recently contributed an improvement to Buildroot that allows those toolchains to very easily be used in Buildroot configurations: the Bootlin toolchains are now all known by Buildroot as existing external toolchains, next to toolchains from other vendors such as ARM, Synopsys and others.


    Internally, this support for Bootlin toolchains in Buildroot is generated and updated using the support/scripts/gen-bootlin-toolchains script. In addition to making the toolchains available to the user, it allows generates some Buildroot test cases for each toolchain, so that each of those configuration is tested by Buildroot continuous integration, see support/testing/tests/toolchain/


  • Intel Vision Processing Unit Patches Updated For The Linux Kernel

    As part of Intel's lengthy "Keem Bay" upstreaming for Linux as their latest-generation Movidius VPU offering, now that much of the core infrastructure bits are all mainlined, the latest focus has been on their Vision Processing Unit enablement. 

    The Intel Vision Processing Unit upstreaming is quite big and includes new xlink-pcie, xlink-ipc, and xlink-core drivers as part of the effort. This VPU was developed through Intel's acquisition of Movidius and can be used for computer vision processing on a locally attached camera or CV processing for a network or tethered camera setup. While most common will be the Keem Bay SoC on a PCI Express card, it can also be found in form factors as a USB dongle or M.2 card as a computer vision accelerator. 

  • Tomasz Torcz: KubeCon NA 2020 talks to watch, part 1 [Ed: Typical Linux Foundation. Slack and Zoom instead of Free software and all projects outsourced to Microsoft's proprietary GitHub]

    The main course of conference are talks. There were plenty. Sometimes there were a dozen or so parallel tracks, so I did not have a chance to watch everything. I'm slowly working through backlog of things I missed. The talks itself were pre-recorded, but after the talk there was a live Q&A session with the speaker. Sadly, the Q&A is not available in recordings below. I guess this was one of the exclusive perks for attendees.

Like in January 2021, a lot of stuff happened for Kate in February 2021, too. I will skip the stuff that I already reported on Valentine’s Day. The web site for example has still a new design and some people are still working behind the scenes to improve it! Let’s take a look at which cool new stuff you can expect to have in the 21.04 release of Kate. If you are adventurous: build the current development version yourself and try the stuff today. Feedback & patches welcome! Read more

Top 10 Version Control Systems for Linux

Version control systems are programs that record changes in filesystems, source code, or software. They are integral to agile software development. Depending on the design, you can categorize them into two types---centralized and distributed. Thankfully, we can choose from several robust version control systems for Linux. This guide outlines some of the best such tools for starting software developers and DevOps professionals. Read more
