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.

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.

  • Not Learning Unix is a Mistake
    It has occurred to me that not learning Unix is a grave mistake. My relatively early exposure to Unix was important. I may not have appreciated Linux as much or even at all if I hadn't had that ability to experiment at home with Xenix. Learning about Unix develops new mental muscles like playing a musical instrument or learning a new language. But learning these new processes becomes more difficult with age. To me the exact technical details are less important. It does not really matter if you are a Linux user or if you use one of the BSDs or even something more exotic like Plan 9. The important thing is you can learn new concepts from what I will broadly refer to as the Unix/Internet Community.
  • Mmm, what's that smell, Google+? Yes it's death: Google unhooks 'social network' from YouTube
    Google is no longer forcing Google+ on the world: people will be able to log into YouTube, and other Googley services, without having to create mandatory Google+ profiles. From now on, only those who deliberately sign up for Google+ will create profiles on the ghost town of a social network. Previously, Google harassed users of YouTube, Gmail and so on, to convert their accounts into Google+ accounts, a move obviously designed to boost G+'s sad numbers. It didn't go down very well at all – a lot of folks hated it.
