  • ARM-Android open source platform for Linaro

    Huawei is backing an initiative for an AOSP (Android open source project) using ARM-based hardware and the Linaro open source collaborative engineering organization to develop the software. Their common aim: an ARM ecosystem.

    The new HiKey 960 dev platform from Huawei is now listed on the 96Boards website and will become available through global distribution channels. It is expected to be of interest to mobile developers and product design for markets like digital signage, point of sale (POS) and robotics.

  • 3 reasons to turn your Raspberry Pi into a DNS server with dnsmasq

    By making DNS requests from a local Raspberry Pi instead of a remote server, you can realize a few advantages. Fetching any kind of data from a local area network will always be faster than fetching something from the Internet.

Using Kdump for examining Linux Kernel crashes

Filed under
Linux

The kexec mechanism has components in the kernel as well as in user space. The kernel provides few system calls for kexec reboot functionality. A user space tool called kexec-tools uses those calls and provides an executable to load and boot the second kernel. Sometimes a distribution also adds wrappers on top of kexec-tools, which helps capture and save the dump for various dump target configurations. In this article, I will use the name distro-kexec-tools to avoid confusion between upstream kexec-tools and distro-specific kexec-tools code. My example will use the Fedora Linux distribution.

  • Ubuntu Is Finally Looking At Shipping Accelerated Video Playback Support

    It's 2017 and Ubuntu is finally looking at shipping GPU-accelerated video playback support out-of-the-box on the Ubuntu desktop.

    Various forms of video acceleration have been available if installing them from the archive on Ubuntu, but nothing has been available by default... But it's looking like that may change, though their direction is a bit peculiar.

  • Netplan by default in 17.10

    Friday, I uploaded an updated nplan package (version 0.24) to change its Priority: field to important, as well as an update of ubuntu-meta (following a seeds update), to replace ifupdown with nplan in the minimal seed.

  • Ubuntu 17.10 To Fully Use Netplan By Default For Network Configuration

    One year after Ubuntu developers announced their Netplan project for consolidated networking configuration across platforms, they are now planning to use Netplan by default in Ubuntu 17.10 across all editions.

    Netplan has picked up many features in the year it's been under development as a replacement to ifupdown. Netplan aims to handle all network configuration use-cases and can in turn generate configuration files for use by NetworkManager and systemd-networkd.

  • Ubuntu 17.10 Continues Aiming For The Linux 4.13 Kernel

    Mentioned in the weekly Ubuntu Kernel Newsletter are the developers reiterating their plans to ship Ubuntu 17.10 "Artful Aardvark" with the Linux 4.13 kernel.

    They've previously expressed plans for shipping Ubuntu 17.10 Artful with Linux 4.13 and this week's newsletter repeats those claims.

Latest quad-core Banana Pi offers SATA support for $32

Debian

SinoVoiP’s open-spec, Linux- and Android-ready “Banana Pi BPI-M2 Berry” SBC has a Raspberry Pi-like layout, WiFi, BT, GbE, HDMI, 4x USB, CSI, and SATA.

SinoVoip’s Banana Pi project has introduced a variation on its $40 Banana Pi M2 Ultra hacker SBC with a smaller, Raspberry Pi like, 85 x 56mm footprint instead of the Ultra’s 92 x 60mm. The quad-core Banana Pi BPI-M2 Berry offers fairly similar features as the Ultra, which is also somewhat like to that of the older, 92 x 60mm Banana Pi M2. The main difference compared to the M2 is that the Berry and the Ultra models add SATA support, and not just the under-powered USB variety.

Hacker Board Survey Results: More Raspberry Pi, Please

Filed under
Linux

The results are in for the 2017 Hacker Board survey. A total of 1,705 Linux.com and LinuxGizmos readers voted for their favorite Linux-driven, community-backed SBCs under $200 out of a catalog of 98. As with last year’s jointly sponsored survey, as well as the 2015 and 2014 polls, a Raspberry Pi single board computer came out on top.

What was remarkable this time around was the huge 4-to-1 gap between the Raspberry Pi 3 and the nearest competitor, which for the first time was also a Raspberry Pi: the Raspberry Pi Zero W. Third place went to the revamped, Cortex-A53 based Raspberry Pi 2.

  • Linus Torvalds and Greg Kroah-Hartman both have new Linux in mind

    Linux lords Linus Torvalds and Greg Kroah-Hartman have clarified Linux's short term future.

    Torvalds took to the Kernel Mailing List to announced release candidate six of Linux 4.12, along with his fervent hope that “this would be a normal release cycle where rc7 is the last rc.”

    If so, that will mean Linux 4.12 will get its last release candidate next weekend and emerge on July 2nd.

    Another eight or nine weeks later we'll get Linux 4.13 and then it will be 4.14's turn in the spotlight.

  • NVMe Now Officially Faster for Emulated Controllers, Thanks to Collabora's Devs

    A year ago, we reported on the performance improvements brought by Collabora's developers to emulated NVMe devices, which were contributed as patches upstream in the Linux 4.8 kernel.

    The patches added huge performance improvements to emulated NVMe devices, but work didn't stop there, and Collabora's Helen Koike is now reporting on the official release in the NVMe Specification Revision 1.3 under the name "Doorbell Buffer Config command."

  • Another Batch Of AMDGPU Feature Updates For Linux 4.13

It brings a bunch of updates and new features to several of its components and apps.
  • Eight years since first release and still no usable theme?
    Well, let me be frank. Ever since gtk-3.0 I've been skeptical of it, especially of the theming aspect. In gtk-2 we had (and still have) many themes ranging from trash to excellent, almost every kind of taste could have been satisfied. Not so in gtk-3. First issue is constant changes to theming API, meaning that despite there being hundreds of themes, only handful of them actually work right :( And among them, I still have yet to find one that would work on my fairly usual 15,6″ laptop screen with 1366×768 px resolution. Basicaly I have two issues.

  • Honda shuts down factory after finding NSA-derived Wcry in its networks
    The WCry ransomware worm has struck again, this time prompting Honda Company to halt production in one of its Japan-based factories after finding infections in a broad swath of its computer networks, according to media reports. The automaker shut down its Sayama plant northwest of Tokyo on Monday after finding that WCry had affected networks across Japan, North America, Europe, China, and other regions, Reuters reported Wednesday. Discovery of the infection came on Sunday, more than five weeks after the onset of the NSA-derived ransomware worm, which struck an estimated 727,000 computers in 90 countries. The mass outbreak was quickly contained through a major stroke of good luck. A security researcher largely acting out of curiosity registered a mysterious domain name contained in the WCry code that acted as a global kill switch that immediately halted the self-replicating attack.
