NVIDIA Contributes Re-Clocking Code To Nouveau For The GK20A

Filed under
Graphics/Benchmarks
Hardware

One of the biggest challenges with the Nouveau open-source graphics driver for NVIDIA graphics hardware in recent times has been with regard to GPU / video memory re-clocking. As a minor step forward, NVIDIA has contributed re-clocking patches for the GK20A graphics processor.

Re-clocking has long been a big challenge for the Nouveau driver to obtain maximum graphics performance while also maintaining optimal performance-per-Watt and being efficient while idling. With the Linux 3.16 kernel for select generations of GPUs is faster performance but it can be buggy while now today for Tegra K1 owners NVIDIA has come to the table with re-clocking code for the "GK20A" GPU found within this high-end NVIDIA ARM SoC.

Linux
Hardware

As we've noted here many times, when it comes to the top open source stories of the past couple of years, it's clear that one of the biggest is the proliferation of tiny, inexpensive Linux-based computers at some of the smallest form factors ever seen. Surely, the diminutive, credit card-sized Raspberry Pi, priced at $25 and $35, is one of the most widely followed of these miniature systems. It's been implemented for use in home security systems, synthesizers and even in a supercomputer mashup using Lego pieces to bind the parts together, as seen in the photo here.

Linux
Hardware

The Odroid-XU3 runs on a 5V 4A power supply, and once again features four energy monitoring chips for tracking the Big.Little cores. A plastic enclosure and an active cooler are available, along with numerous optional modules. OS support has been boosted to Android 4.4.2 and Ubuntu 14.04, available with full source code.
Schematics will be posted upon shipment, and community support is available via the Odroid project. The quad-core Exynos4412 based Odroid-U3 board came in at third place after the Raspberry Pi and BeagleBone Black in our recent Top 10 Hacker SBC survey.

The Novena Open Hardware Laptop: A Hacker's Dream Machine

Hardware
OSS

Would you buy a high-end laptop built completely around open hardware and the Linux distro of your choice? Novena offers that opportunity, but it comes with an out-of-the-box experience that might be beyond the reach of the typical computer consumer.

That said, the Novena laptop's experimental technology has the potential to offer new options to a sluggish computer industry. Novena is an open-hardware computing platform that is flexible and powerful. It is designed for use as a desktop, laptop or standalone board.

Two engineers cofounded Sutajio Ko-usagi, an operations-oriented company focused on the manufacturing and sales of hardware to OEMs and hobbyists.

Since Sutajio Ko-usagi is difficult to pronounce in English, the Novena developers shortened it to "Kosagi," noted cofounder Andrew "Bunnie" Huang. Huang also runs the IP-oriented Bunniestudios

Hardware

TI unveiled a 1GHz, Cortex-A9 Sitara “AM437x” SoC with a 3D GPU, a Linux SDK, and an updated PRU module for dual simultaneous control of fieldbus protocols.

The Sitara AM437x is a major upgrade to the Texas Instruments Sitara AM335x, as well as the related Sitara AM3715 and Sitara AM3874. The Sitara AM437x is said to offer up to 40 percent more processing power than previous Sitara processors.

The Sitara AM437x begins sampling in July, and is available as part of a Linux-ready, $599 TMDXEVM437X evaluation kit (see farther below). Like other Sitara SoCs, the AM437x is aimed primarily at industrial applications. Suggested pairings include factory automation, Programmable Logic Controllers (PLCs), home automation gateways, Internet of Things (IoT) gateways, and human machine interface (HMI).

Automation controller taps Raspberry Pi Compute Module

Hardware

Techbase has designed a Raspberry Pi Compute Module into a Linux-based “ModBerry” automation computer backed by an “iMod” cloud platform for remote control.

The computer-on-module version of the Raspberry Pi Compute Module, which began shipping this week, was anticipated by many, but perhaps nowhere so acutely as in Poland. First, we heard about A Sherlybox private cloud storage device based on the module from Polish startup Sher.ly, and now Gdansk-based industrial computer manufacturer Techbase has opened pre-orders for an automation computer called the ModBerry 500 based on the COM.

Outside of Logitech, there's many Linux users that have come up with several different open-source utilities for supporting Logitech under Linux. For most of these apps the hardware support is limited to the few keyboards/mice that the developer owns, but it isn't too hard reverse-engineering a USB keyboard for others to help out and contribute.

Intel and Clear Linux Project

  • Intel wants containers to be alone again, naturally
    Intel reckons that's harder to do with Linux containers as “underlying kernel still can be attacked from within the container.” That's bad because it means “all containers on the same host can be compromised, regardless of the intended isolation between them,” making multitennacy risky and therefore unlikely.
  • Docker Drives Interest in App Containerization Technologies
    The biggest example is CoreOS, a heavily venture-backed startup based in San Francisco that has already gained some early attention as a potential alternative to Docker. The company’s open source project dubbed Rocket has won backing from powerhouses like Google and Intel and others like Red Hat and VMware.
  • Intel offers hardware-level answer to container security challenges
    Intel has become the latest vendor to throw its weight behind the push to solve the security woes of containers with the launch of a new technology that promises to address the risks currently standing in the way of widespread production use from the hardware level up. It’s the latest fruit of the internal Clear Linux Project.
  • Intel wants data containers alone again
    The downside is that it does not work well with Linux containers as underlying kernel still can be attacked from within the container and all containers on the same host can be compromised.
  • What are containers and why do you need them?
    Containers are a solution to the problem of how to get software to run reliably when moved from one computing environment to another. This could be from a developer's laptop to a test environment, from a staging environment into production and perhaps from a physical machine in a data center to a virtual machine in a private or public cloud.
