  • DragonFlyBSD Finalizes Its Ryzen Workaround

    Separate from the AMD Ryzen performance marginality problem affecting Linux users, BSD users have been working on a workaround for their kernels to address problems with how their user stacks are mapped.

    A link circulating earlier this month was this FreeBSD commit to work around a guard page issue. Issues (funky behavior) can occur if code is running at the top of the user memory address space, so the workaround is to increase the guard page size. Linux has already had a large guard page while the BSDs have not, but they are now being increased for Ryzen.

  • BSDCam 2017 Trip Report: Michael Lucas

     

    BSDCam attendance is invitation only, and the facilities can only handle fifty folks or so. You need to be actively working on FreeBSD to wrangle an invite. Developers attend from all over the world. Yet, there’s no agenda. Robert Watson is the chair, but he doesn’t decide on the conference topics. He goes around the room and asks everyone to introduce themselves, say what they’re working on, and declare what they want to discuss during the conference. The topics of interest are tallied. The most popular topics get assigned time slots and one of the two big rooms. Folks interested in less popular topics are invited to claim one of the small breakout rooms.

  • openbsd changes of note 626
  • kcollect description
  • New mechanism: kcollect

    There’s a new facility in DragonFly: kcollect(8). It holds automatically-collected kernel data for about the last day, and can output to gnuplot. Note the automatic collection part; your system will always be able to tell you about weirdness – assuming that weirdness extends to one of the features kcollect tracks.

  • Contributing to FreeBSD

     

    The FreeBSD Testing Project is building an automated test suite for the entire operating system. They have a whole mess of work to do. There’s only four people on the team, so each additional person that contributes can have a serious impact. They have tutorials on how to write tests, and sample tests.

BSD/UNIX: Trying OpenIndiana Hipster On The Core i9 7900X and 'End' of Bitrig

  • Trying OpenIndiana Hipster On The Core i9 7900X

    Following the Linux and BSD multi-threaded tests on the Intel Core i9 7900X, I next decided to try this system with the Solaris-based OpenIndiana. Sadly, it didn't end well.

    With various BSDs working fine on the Core i9 7900X box paired with the NVMe storage, MSI X299 SLI PLUS motherboard, etc, I figured OpenIndiana would play fine. Sadly, I was wrong.

  • Bitrig: The Short-Lived OpenBSD Fork

    Bitrig, the operating system that forked OpenBSD back in 2012, is no longer being developed.

    Bitrig saw its initial release in 2014 but it's been relatively quiet since. In fact, pretty much forgotten on my end until seeing an LLVM commit this week mentioning Bitrig is dead and has been merged back into OpenBSD.

    Further showing the project is no more is the GitHub project area showing no more work since 2016.

  • Milestone Complete! OpenRC conversion

    The OpenRC conversion project is done! Over one thousand script/port conversions are complete, and all will be available in the TrueOS UNSTABLE and STABLE tracks soon. The project wants to extend a huge thank you to all those who contributed to completing this milestone, and a special thank you to contributors ZackaryWelch and elarge011 for doing the lion’s share of the work.

  • TrueOS Finishes Porting Scripts To OpenRC

    The TrueOS BSD distribution has finished porting over more than one thousand FreeBSD RC scripts into OpenRC format for this dependency-based init system.

    This year the TrueOS crew has been working on migrating to the OpenRC init system for better boot performance, easier configuration, better organization of configuration files, more reliable service status, etc. Popular services had been in OpenRC form already but now they have finished porting over more than 1,000 other scripts for OpenRC on TrueOS.

  • mandoc-1.14.2 released

     

    With the improved mandoc features, only twenty-five out of the ten thousand software packages in the OpenBSD ports tree still need groff to format their manual pages.

Baidu puts open source deep learning into smartphones

A year after it open sourced its PaddlePaddle deep learning suite, Baidu has dropped another piece of AI tech into the public domain – a project to put AI on smartphones. Mobile Deep Learning (MDL) landed at GitHub under the MIT license a day ago, along with the exhortation “Be all eagerness to see it”. MDL is a convolution-based neural network designed to fit on a mobile device. Baidu said it is suitable for applications such as recognising objects in an image using a smartphone's camera.

AMD and Linux Kernel

  • Ataribox runs Linux on AMD chip and will cost at least $250
    Atari released more details about its Ataribox game console today, disclosing for the first time that the machine will run Linux on an Advanced Micro Devices processor and cost $250 to $300. In an exclusive interview last week with GamesBeat, Ataribox creator and general manager Feargal Mac (short for Mac Conuladh) said Atari will begin a crowdfunding campaign on Indiegogo this fall and launch the Ataribox in the spring of 2018. The Ataribox will launch with a large back catalog of the publisher’s classic games. The idea is to create a box that makes people feel nostalgic about the past, but it’s also capable of running the independent games they want to play today, like Minecraft or Terraria.
  • Linux 4.14 + ROCm Might End Up Working Out For Kaveri & Carrizo APUs
    It looks like the upstream Linux 4.14 kernel may end up playing nicely with the ROCm OpenCL compute stack, if you are on a Kaveri or Carrizo system. While ROCm is promising as AMD's open-source compute stack complete with OpenCL 1.2+ support, its downside is that for now not all of the necessary changes to the Linux kernel drivers, LLVM Clang compiler infrastructure, and other components are yet living in their upstream repositories. So for now it can be a bit hairy to setup ROCm compute on your own system, especially if running a distribution without official ROCm packages. AMD developers are working to get all their changes upstreamed in each of the respective sources, but it's not something that will happen overnight and given the nature of Linux kernel development, etc, is something that will still take months longer to complete.
  • Latest Linux kernel release candidate was a sticky mess
    Linus Torvalds is not noted as having the most even of tempers, but after a weekend spent scuba diving a glitch in the latest Linux kernel release candidate saw the Linux overlord merely label the mess "nasty". The release cycle was following its usual cadence when Torvalds announced Linux 4.14 release candidate 2, just after 5:00PM on Sunday, September 24th.
  • Linus Torvalds Announces the Second Release Candidate of Linux Kernel 4.14 LTS
    Development of the Linux 4.14 kernel series continues with the second Release Candidate (RC) milestone, which Linus Torvalds himself announces this past weekend. The update brings more updated drivers and various improvements. Linus Torvalds kicked off the development of Linux kernel 4.14 last week when he announced the first Release Candidate, and now the second RC is available packed full of goodies. These include updated networking, GPU, and RDMA drivers, improvements to the x86, ARM, PowerPC, PA-RISC, MIPS, and s390 hardware architectures, various core networking, filesystem, and documentation changes.
