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

Linux
  • 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.

Linux
OSS

MYIR released an add-on board for its Linux-driven, i.MX6 UL-based MYS-6ULX SBC that adds a second LAN port, plus CAN, RS485, camera, audio, and RTC.

In April, MYIR released a Linux-powered MYS-6ULX SBC, which was notable for being available in two different versions using NXP’s low power, Cortex-A7 i.MX6 UltraLite (UL) or the more affordable, and almost identical i.MX6 ULL SoC. Now, MYIR has released an “MYB-6ULX Expansion Board” designed to stack onto either model. The $21.20 accessory adds a second 10/100 Ethernet port to the MYS-6ULX, as well as new CAN, RS485, audio, micro-USB, RTC, and camera functions.

Linux
  • Introducing The Linux Foundation’s Open Source Networking Days

    One of my primary goals at The Linux Foundation is to foster innovation across the entire open source networking ecosystem. This involves coordinating across multiple open source projects and initiatives and identifying key areas for collaboration to create an open source networking stack.

    We are working across the entire ecosystem with industry-leading partners — from developers to service providers to vendors — to unify various open source components and create solutions that will accelerate network transformation. As part of this journey, I am pleased to introduce Open Source Networking Days (OSN Days), a series of free events that are hosted and organized by local user groups and The Linux Foundation members, with support from our projects, including DPDK, FD.io, ONAP, OpenDaylight, OPNFV, PNDA, and others.

  • Randa news, release update

    Last week, from wednesday to saturday I attended KDE’s annual Randa sprint organized by wonderful people. This was an occasion to work fulltime on Kdenlive.

Linux

BeagleBoard.org’s $25 “PocketBeagle” USB key-fob BeagleBone clone is based on the Octavo OSD3358-SM SiP module, and offers micro-USB and microSD links.

BeagleBoard.org has released its smallest BeagleBone variant yet. The COM-like, 56 x 35 x 5mm PocketBeagle is a USB key-fob SBC built on the Octavo Systems OSD335x-SM System-In-Package (SiP) module that was announced earlier this week. Octavo’s 21 x 21mm SiP module, which packs a 1GHz Texas Instruments Sitara AM3358 SoC and nearly all the functions of a BeagleBone Black SBC into a BGA form factor, is 40 percent smaller than the original 27 x 27mm OSD335x.

  • Adding More Policy Firepower to the Mozilla Network
    In June, Mozilla launched a new fellowship that brings together policy experts from around the world to advance crucial tech policy efforts. Today, we are excited to announce the appointment of seven advisors to help steer this fellowship into the future. We are also announcing one new fellow, bringing the cohort to 11 fellows from four countries who are already up to great work. Over the past three months, Mozilla’s Tech Policy Fellows have been digging into their projects to keep the Internet open and freely accessible to all. With most fellows joining directly out of government service, they’re continuing to move forward some of the urgent policy efforts they had been leading, and working to avoid any backsliding that might come with government transitions. The fellows’ work is focused on protecting net neutrality, advancing policies around artificial intelligence and the Internet of Things, promoting affordable broadband service for vulnerable communities, and more. Amba Kak is our most recent addition, starting this month to work on promoting net neutrality in India. To advance this work, the fellows are meeting with policymakers inside and outside of government; they’re keynoting major events and giving press interviews about the importance of these topics; and in the coming weeks, they’ll share more about their work with the Mozilla network on our network blog.

    So in a sense I have been part-time part of the FreeBSD Community for nearly 15 years as well. FreeBSD has reached Tier-1 status within KDE now, with the KDE FreeBSD CI, which much stronger upstreaming happening, and with Tobias and Raphael following new releases pretty closely. I’ve been pushing and prodding at our ports tree a lot, and chasing CMake releases (and reporting bugs), and trying to get some KDE KF5-based applications into the official ports tree. So I’m happy to now receive a FreeBSD ports commit bit, with Tobias and Raphael acting as mentors. I won’t pretend this will immediately lead to Qt 5.9 and KDE Applications 17.latest in the official FreeBSD ports tree, but it increases the (direct) effort we can expend on it.
  • Free the Seed: An Open Source Approach to Food Crop Seed
    We Americans value the freedom to do what we want with our property. These days, our freedom of action in regard to what we own is increasingly being eroded and constrained by the expansion of corporate power and the evolving legal dimensions of ownership. Nowhere has this tendency to limit freedom to operate come into sharper focus than in farming. A farmer may buy a John Deere tractor, but ownership of the copyrighted software—without which the tractor cannot run and cannot be repaired—is retained by the company. According to Deere, the farmer has “an implied lease” to operate the tractor but is prohibited from making any repair or change involving use of the copyrighted code.
  • Synthace raises a £7.3m Series A to bring open source to biotech
    Synthace, a UK startup using open source technology to make process in biotechnology move faster, has raises a £7.3m Series A round. New investors White Cloud Capital, Amadeus Capital Partners and Eleven Two Capital participated alongside existing investors that included Sofinnova Partners, SOSV and Bioeconomy Capital. The Company’s Antha operating system replaces processes which are currently done, almost, by hand. CEO Tim Fell says the company came out of the desire to better engineer biology: “Our need to heal, feed, fuel and manufacture for a growing population can be met by unlocking the near infinite power of biology but only by bringing software abstraction and more automation to biological R&D and manufacturing, and by enabling biologists to build atop their collective work. That is what the Antha platform does.”
