LWN (Now Open Access): Kernel Configuration, Linux 4.14 Merge Window, Running Android on a Mainline Graphics Stack

  • A different approach to kernel configuration

    The kernel's configuration system can be challenging to deal with; Linus Torvalds recently called it "one of the worst parts of the whole project". Thus, anything that might help users with the process of configuring a kernel build would be welcome. A talk by Junghwan Kang at the 2017 Open-Source Summit demonstrated an interesting approach, even if it's not quite ready for prime time yet.

    Kang is working on a Debian-based, cloud-oriented distribution; he wanted to tweak the kernel configuration to minimize the size of the kernel and, especially, to reduce its attack surface by removing features that were not needed. The problem is that the kernel is huge, and there are a lot of features that are controlled by configuration options. There are over 300 feature groups and over 20,000 configuration options in current kernels. Many of these options have complicated dependencies between them, adding to the challenge of configuring them properly.

  • The first half of the 4.14 merge window

    September 8, 2017 As of this writing, just over 8,000 non-merge changesets have been pulled into the mainline kernel repository for the 4.14 development cycle. In other words, it looks like the pace is not slowing down for this cycle either. The merge window is not yet done, but quite a few significant changes have been merged so far. Read on for a summary of the most interesting changes entering the mainline in the first half of this merge window.

  • Running Android on a mainline graphics stack

    The Android system may be based on the Linux kernel, but its developers have famously gone their own way for many other parts of the system. That includes the graphics subsystem, which avoids user-space components like X or Wayland and has special (often binary-only) kernel drivers as well. But that picture may be about to change. As Robert Foss described in his Open Source Summit North America presentation, running Android on the mainline graphics subsystem is becoming possible and brings a number of potential benefits.
    He started the talk by addressing the question of why one might want to use mainline graphics with Android. The core of the answer was simple enough: we use open-source software because it's better, and running mainline graphics takes us toward a fully open system. With mainline graphics, there are no proprietary blobs to deal with. That, in turn, makes it easy to run current versions of the kernel and higher-level graphics software like Mesa.

Android/Linux Devices: Fire OS/Fire HD, Chromebook Pixel, Pixel 2 XL

  • New Amazon Fire HD 10 adds full HD display, hands-free Alexa

    Amazon has made concessions to hit that price point, of course—mostly via the limitations of Fire OS—but let's start with the good stuff. The 10.1-inch, 1920×1200 pixel IPS screen is colourful, bright, and has excellent viewing angles. It's laminated to the glass, too, making it clear and easy to read. The shiny rear surface of the old Fire 10 has been given the shove, replaced with a hard-wearing, textured plastic that provides plenty of grip, without feeling cheap (or, at least more premium than the price tag suggests).

  • Meet the really cheap Google Home Mini and really expensive Chromebook Pixel 3

    Android fansite Droid Life is on fire today with a big series of leaks of Google's upcoming hardware launches. After showing off pictures and pricing for the Pixel 2 and Pixel 2 XL, the site has details on the new "Google Home Mini," a second smartphone-powered Daydream VR headset, and a new flagship Chromebook Pixel.

    First up is the new "Google Home Mini," a smaller version of the Google Home, which will retail for just $50. The colors here are "Chalk" (white/grey), "Charcoal" (black), and "Coral" (red). Like the Amazon Echo Dot, the Google Home Mini skips the thumping speaker setup for a smaller, cheaper form factor meant more for commands and Q&A sessions rather than for music.

  • The Pixel 2 XL price jumps $80, now starts at $849

Kernel and Graphics: ZenStates, AMDGPU, RADV, Vulkan, NVIDIA

  • ZenStates Allows Adjusting Zen P-States, Other Tweaking Under Linux
    ZenStates is an independent effort to offer P-States-based overclocking from the Linux desktop of AMD Ryzen processors and other tuning. ZenStates-Linux is an open-source Python script inspired by some available Windows programs for offering Ryzen/Zen CPU overclocking from the desktop by manipulating the performance states of the processor.
  • AMDGPU DC Gets A Final Batch Of Changes Before Linux 4.15
    The AMDGPU DC display code has a final batch of feature updates that were sent in this weekend for DRM-Next staging and is the last set besides fixes for the "DC" code for the 4.15 target.
  • Valve Developer Lands VK_EXT_global_priority For RADV Vulkan Driver
  • Vulkan 1.0.64 Adds In Another AMD-Developed Extension
    Vulkan 1.0.64 is out this weekend as the newest specification refinement to this high-performance graphics/compute API. As usual, most of the changes for this minor Vulkan revision are just documentation clarifications and corrections. This week's update brings just under a dozen fixes.
  • NVIDIA TX2 / Tegra186 Display Support Isn't Ready For Linux 4.15
    While the Jetson TX2 has been out since this past March and it's a phenomenal ARM development board, sadly the Direct Rendering Manager (DRM) driver support for it still isn't ready with the mainline Linux kernel. Thierry Reding of NVIDIA sent in the Tegra DRM driver changes for DRM-Next that in turn is staged for Linux 4.15. Reding commented that there is prepatory work for the TX2 (Tegra186) but it's not all ready for upstream yet.

Ubuntu: Mir running on Fedora and Ubuntu 17.10 Guidance

  • Mir running on Fedora
    Last week we released Mir 0.28 and this week we settled down to tidy up a few bugs fixes and feature requests that didn’t make the release. I’ve started collecting these for a Mir 0.28.1 release to come in the next few weeks. The most interesting of these comes from conversations at the Ubuntu Rally: there were several requests from community members around getting Mir working (or even building!) on other distributions.
  • Ubuntu Developer Gets Mir Running On Fedora
    Lead Mir developer Alan Griffiths has spent the time getting the Mir display server running on Fedora. This is part of a broader feature request of getting Mir running on more Linux distributions than just Ubuntu. The changes to get Mir running on at least Fedora should be merged for the upcoming Mir 0.28.1 point release. Mir 0.28.1 will also incorporate other bug fixes.
