Re-Clocking Your NVIDIA GPU With Nouveau On Linux 3.17

Filed under
Linux
Hardware

If you are trying to re-clock your NVIDIA GPU with the Nouveau driver when using the Linux 3.17 kernel, there's an extra step involved, but still your mileage may vary and the re-clocking is still mostly for Kepler GPUs.

With the Nouveau driver changes for Linux 3.17 there are no magic breakthroughs when it comes to re-clocking -- allowing the GPU's core and memory clocks to run at their rated frequencies and voltages rather than any (often much lower) values programmed by the video BIOS at boot time. With Linux 3.17 came re-clocking for Kepler GPUs and now it works, but generally not all performance levels/states properly function. If you are running a GeForce 400/500 "Fermi" GPU or other generations of NVIDIA hardware aside from the few integrated mobile chipsets, chances are you're out of luck in being able to tap the full potential of the GPU when using this open-source, reverse-engineered NVIDIA GPU.

Eltechs Debuts x86 Crossover Platform for ARM Tablets, Mini-PCs

Filed under
Linux
Hardware
Software

The product, called ExaGear Desktop, runs x86 operating systems on top of hardware devices using ARMv7 CPUs. That's significant because x86 software, which is the kind that runs natively on most computing platforms today, does not generally work on ARM hardware unless software developers undertake the considerable effort of porting it. Since few are likely to do that, having a way to run x86 applications on ARM devices is likely to become increasingly important as more ARM-based tablets and portable computers come to market.

That said, the ExaGear Desktop, which Eltechs plans to make available next month, currently has some steep limitations. First, it only supports Ubuntu Linux. And while Eltechs said support for additional Linux distributions is forthcoming, there's no indication the product will be able to run x86 builds of Windows on ARM hardware, a feat that is likely to be in much greater demand than Linux compatibility.

Ruth Suehle and Tom Callaway are presenting at LinuxCon 2014 Chicago tomorrow about many different Raspberry Pi hacks and other Linux capabilities of these low-cost, low-performance single board computers.

The two Fedora contributors cover the back-story of the Raspberry Pi for anyone that's been sleeping under a rock, how to go about getting parts for the RPi, and the process to get Linux running on the ~$35 ARMv6 system. With Linux running on the Raspberry Pi, the possibilities are nearly endless for this low-cost development-friendly board.

According to a new DigiTimes report, sales of credit-card sized Raspberry Pi devices, which run Linux, remain very strong. The Raspberry Pi Foundation says that 3.5 million units have sold worldwide, with demand from China and Taiwan staying strong. The devices are helping to teach children basic programming skills and are arriving in educational systems all around the world.

Raspberry Pi needs no introduction. It is one of the most popular credit card sized single board computers which has become a revolution in its own right. The $25 (and $35 for B model) hardware is being used in so many fields that it’s hard to keep a tab on it.

Project aims to build “fully open” SoC and dev board

Filed under
Hardware
OSS

A non-profit company is developing an open source, 64-bit “lowRISC” SoC that will enable fully open hardware, “from the CPU core to the development board.”

University of Cambridge spinoff “lowRISC” is a not-for-profit company with a goal of making a completely open computing eco-system, including the instruction set architecture (ISA), processor silicon, and development boards. The first step is to develop a new system-on-chip design based on the new, 64-bit RISC-V ISA developed at the University of California, Berkeley.

Linux-based controller mixes Atom SoC with Kintex-7 FPGA

Filed under
Linux
Hardware

NI’s new 4-slot CompactRIO control system combines a dual-core Atom E3825 with a Kintex-7 FPGA, and features industrial temperatures and NI Real-Time Linux.

The National Instruments (NI) “CompactRIO 4-slot Performance Controller” is the high end “performance” big brother to NI’s “value” CompactRIO cRIO-9068 model, introduced a year ago. Whereas the cRIO-9068 runs NI Linux Real-Time OS on a Xilinx ARM+FPGA hybrid Zynq-7020 system-on-chip, the new CompactRIO splits processing duty between an Intel Atom processor and a higher-end Xilinx Kintex-7 325T FPGA. The CompactRIO uses a dual-core, 1.33GHz Atom E3825 SoC from the latest, 22nm Bay-Trail-I generation, featuring a relatively low, 6 Watt TDP.

Raspberry Pi-powered Bigtrak

Filed under
Hardware
Gadgets

The Raspberry Pi is a small, low-cost computer designed to promote an interest in computing and programming – but it doesn’t have to be straight-laced computing. In fact, in this article we’ll be showing you how you can use it to turn a Bigtrak into a robot. That’s educational, right?

The Bigtrak is a toy that takes in a list of straightforward commands (Go forwards, turn left, turn right) and then executes them. To make things more interesting we’re going to remove the existing circuitry and replace it with a Raspberry Pi, using a small motor driver to safely control the motors in the Bigtrak, which we’ll then set up to be controlled via a PlayStation 3 DualShock controller.

Everything required on the software side comes pre- installed on the latest Raspbian OS images, so all we need to translate changes from the controller to the motors is a small Python script that uses the Pygame and RPI.GPIO modules.

Storm Energy has upgraded its “SunSniffer” solar plant monitoring system to a Linux-based platform running on a Raspberry Pi SBC.

Germany-based Storm Energy is the latest of a growing number of companies building commercial products based on the hackable Raspberry Pi single board computer. The company’s SunSniffer system is designed to monitor photovoltaic (PV) solar power installations of all sizes, and the latest version can also control the equipment, says the company. The new SunSniffer version adds a Raspberry Pi SBC along with a custom expansion board and customized Linux OS, which combine to enhance the system’s flexibility and upgradability.

Leftovers: Ubuntu

  • Ubuntu-based Smartphones And Tablets Sound Good, On Paper, But...Do They Make Any Sense?
    As I previously stated in a recent article, I'm a huge fan of Ubuntu as a desktop operating system. It's friendly, reliable, consumes little resources and is largely virus-free.
  • Elementary OS 0.4 ‘Loki’ expected to be based on Ubuntu 16.04
    Elementary OS 0.4 ‘Loki’ coming soon, to be based on Ubuntu 16.04 and have plenty of new features
  • BQ Aquaris M10 Ubuntu Edition tablet - The heat is on
    Some investments are financial. Some are emotional. When it comes to Linux on tablets, my motives are mostly of the latter kind. I was super-excited to learn BQ was launching a tablet with Ubuntu, something that I have been waiting for a good solid three years now. We had the phone released last spring, and now there's a tablet. The cycle is almost complete. Now, as you know, I was only mildly pleased with the Ubuntu phone. It is a very neat product, but it is not yet as good as the competitors, across all shades of the usability spectrum. But this tablet promises a lot. Full HD, desktop-touch continuum, seamless usage model, and more. Let us have a look.
  • Kubuntu-16.04 — a review
    The kubuntu implementation of Plasma 5 seems to work quite well. It’s close to what I am seeing in other implementations. It includes the Libre Office software, rather than the KDE office suite. But most users will prefer that anyway. I’m not a big fan of the default menu. But the menu can easily be switched to one of the alternative forms. I’ve already done that, and am preferring the “launcher based on cascading popup menus”. If you are trying kubuntu, I suggest you experiment with the alternative formats to see which you prefer.
  • Ubuntu 16.04 LTS Review: Very Stable & Improved, Buggy Software Center, Though
    In almost all the occasions that I tested Ubuntu LTS releases, quite rightly so, they’ve always worked better than the non-LTS releases. And this Ubuntu 16.04 LTS, the 6th of such release is no exception. This one actually is even more impressive than the others because it has addressed some security related issues and even although not critical, subtle issues that I mentioned in the review. As far as the performance was concerned, Ubuntu 16.04 LTS was only largely outperformed by the memory usage where there is a large increase in memory usage. Other than that, those numbers look pretty good to me. That ‘.deb’ file issues with the Software Center is the only major concern that I can come up with. But I’m sure it’ll be fixed very soon.

Devuan Beta, Stumbling Tumbleweed, Ubuntu Too
