Embedded Development with ARM mbed on Linux

Filed under
Linux

The ARM CPU used in the BeagleBone Black and other single board computers is designed to interface with half to a few gigabytes of RAM and allow a full operating system such as Linux to be run on the computer. (See my long series of reviews on Linux.com of ARM-based computers that run Linux). By contrast the ARM Cortex-M is a microcontroller level chip which might run at 16-100Mhz, contain 2-100kb of RAM, and some flash memory to contain only the program that you want to execute.

IoT, Revolution In Personal Computing, or FLOSS Taking Over the World of IT

Filed under
GNU
Linux

What can you say? In a few short years, that other OS has gone from mainstream to niche and Android/Linux and GNU/Linux are stepping up to displace it as the goto OS of the world. It’s all good. This is the right way to do IT with the world making its own software throughout the whole stack: OS on client and server and a ton of applications too. There is no need for a monopoly in IT. The world wants a revolution not lock-in.

Just Switch to Linux if You Want to Download Lots of Freeware

Filed under
Linux

We’ve been banging on about the horrific and broken Windows software ecosystem for a long time now. Rather than installing applications from Download.com and every other freeware site, you should just switch to Linux if you want to download freeware safely.

Yes, we’ve tried to recommend some tips, but the only really good one we can come up with is “just use Ninite.” “Just switch to Linux if you want to download freeware” is another good one.

NVIDIA's Latest Maxwell Line-Up Against AMD With Catalyst On Linux

Graphics/Benchmarks
Linux

Last week NVIDIA released the GeForce GTX 960, a great $200 GPU for Linux gamers that is based on their new power-efficient Maxwell architecture. On launch-day I delivered some initial performance figures of the full GeForce GTX 900 series line-up along with other graphics cards and following that I did many new NVIDIA Linux GPU tests going back to the GeForce GTX 400 (Fermi) series. Not part of those tests were any AMD Radeon graphics cards while in this article are such numbers in making a new 18-way graphics card comparison with the latest Linux graphics drivers.

Linux Desktop Evolution: Minor, Invisible, or Aesthetic

Filed under
GNU
Linux

In the last two years, the Linux desktop has settled into a period of quiet diversity. The user revolts of 2008-2012 are safely in the past, and users are scattered among at least seven major desktops -- Cinnamon, GNOME, KDE,LXDE, MATE, Unity, and Xfce -- and likely to stay that way.

So what comes next? What will the next innovations on the desktop be? Where will they come from? Prediction is as safe as investing in penny mining stocks, but some major trends for the next couple of years seem obvious without the bother of a tarot reading.

NVIDIA Tegra DRM Driver Supports Atomic Mode-Setting In Linux 3.20

Filed under
Linux

The latest work landing in the DRM-Next code-base for the Linux 3.20 kernel merge window is the Tegra DRM driver updates.

The Tegra DRM driver is primarily designed to support the Tegra 4 and older SoCs while the Tegra K1 and newer is supported by the Nouveau DRM driver due to the graphics core now being common with their mainline desktop architecture. The Tegra K1's GK20A graphics core is derived directly from Kepler while the brand new Tegra X1 is derived from Maxwell. Regardless, the Tegra DRM driver continues to be actively developed by NVIDIA stakeholders.

Embedded Linux Conference hijacked by drones

Filed under
Linux

The Embedded Linux Conference + Android Builders Summit on Mar. 23-25 in San Jose is about “Drones, Things, and Automobiles,” but drones get the most love.

Maybe it’s just our imagination, but the Linux Foundation’s Embedded Linux Conference seems to be getting more interesting than ever. The program increasingly reflects new opportunities for Linux in areas such as drones, robots, automotive computers, IoT gizmos, 3D sensing, modular phones, and much more. For those of you worried that ELC North America is skimping on the basics as it explores the more colorful sides of Linux, rest your mind at ease. There are still plenty of sessions on booting, trace analysis, NAND support, PHY frameworks, power management, defragmenting, systemd, device tree, and toolchain. Geeks still rule!

  • Session suspension and restoration protocol
  • A Session Suspension & Restoration Protocol Proposed For Wayland
    KDE Wayland developer Roman Gilg who started contributing to Wayland via last year's Google Summer of Code is proposing a new Wayland protocol for dealing with desktop session suspension and restoration. This protocol extension would allow for more efficient support for client session suspension and restoration such as when you are logging out of your desktop session and want the windows restored at next log-in or if you are suspending your system. While Roman Gilg is working on this protocol with his KDE hat on, he has been talking with Sway and GNOME developers too for ensuring this protocol could work out for their needs.
  • RadeonSI Lands OpenGL 3.3 Compatibility Profile Support
    Thanks to work done over the past few months by AMD's Marek Olšák on improving Mesa's OpenGL compatibility profile support and then today carried over the final mile by Valve's Timothy Arceri, Mesa 18.2 now exposes OpenGL 3.3 under the compatibility context. Hitting Git tonight is the enabling of the OpenGL 3.3 compatibility profile for RadeonSI.

Server Domination by GNU/Linux

  • Security and Performance Help Mainframes Stand the Test of Time
    As of last year, the Linux operating system was running 90 percent of public cloud workloads; has 62 percent of the embedded market share and runs all of the supercomputers in the TOP500 list, according to The Linux Foundation Open Mainframe Project’s 2018 State of the Open Mainframe Survey report. Despite a perceived bias that mainframes are behemoths that are costly to run and unreliable, the findings also revealed that more than nine in 10 respondents have an overall positive attitude about mainframe computing. The project conducted the survey to better understand use of mainframes in general. “If you have this amazing technology, with literally the fastest commercial CPUs on the planet, what are some of the barriers?” said John Mertic, director of program management for the foundation and Open Mainframe Project. “The driver was, there wasn’t any hard data around trends on the mainframe.”
  • HPE announces world's largest ARM-based supercomputer
    The race to exascale speed is getting a little more interesting with the introduction of HPE's Astra -- what will be the world's largest ARM-based supercomputer. HPE is building Astra for Sandia National Laboratories and the US Department of Energy's National Nuclear Security Administration (NNSA). The NNSA will use the supercomputer to run advanced modeling and simulation workloads for things like national security, energy, science and health care.
