Docker Founder Must Right His Ship

Filed under

Server

Success can build a feedback loop that sustains its own momentum, making those who are successful certain they are doing the right thing. I don't want to charge Docker with such hubris, but recent events illustrate why open source code projects function the way they do.

Interviews

A Reddit AMA last week with Greg Kroah-Hartman, Linux kernel developer and Linux Foundation Fellow, went beyond the usual questions about his workstation setup and job description. Much of that was preempted by Kroah-Hartman's lengthy list of resources where the un-initiated can find his previous writing and presentations on those topics. Instead, he was able to answer more timely and specific questions which ranged from his thoughts on specific kernel patches, to the overall development process, to personal questions about his family, work habits and favorite beer. Below is an edited digest of some of the best responses. Visit the r/linux subreddit for the full AMA.

New Features On The Horizon For The Linux Kernel

Filed under
Linux

Besides the many Linux graphics driver changes for Linux 3.19, there's many other non-graphics features out on the horizon in kernel land -- some of which might land in Linux 3.19 but most of the other items are post-3.19 material. Linux 4.0 also isn't likely far out.

Seems like a great idea to me. It makes sense to prepare inmates for life outside of prison with useful skills, and the Linux job market is certainly hot right now.

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.
