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.

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.

GeckoLinux 421 Plasma and SUSE Hack Week

  • GeckoLinux 421 Plasma review - It ain't no dragon
    I heard a lot of good praise about this little distro. My inbox is flooded with requests to take it for a spin, so I decided, hey, so many people are asking. Let us. The thing is, openSUSE derivatives are far and few in between, but the potential and the appeal are definitely there. Something like CentOS on steroids, the way Stella did once, the same noble way Fuduntu tried to emancipate Fedora. Take a somewhat somber distro and pimpify it into submission. GeckoLinux is based on openSUSE Leap, and I chose the Plasma Static edition. There's also a Rolling version, based on Tumbleweed, but that one never worked for me. The test box for this review is Lenovo G50. But wait! Dedoimedo, did you not recently write in your second rejection report that GeckoLinux had failed to boot? Indeed I did. But the combo of yet another firmware update on the laptop and a fresh new download fixed it, allowing for a DVD boot. Somewhat like the painful but successful Fedora exercise back in the day. Tough start, but let's see what gives.

From Vista 10 to Linux Mint

  • Microsoft Scared into Changes, 5 Reasons to Ditch
    Following a small claims court judgment against them, Microsoft announced they would be making declining their Windows 10 upgrade easier. Why not just switch to Linux as Daniel Robinson highlighted five reasons you should. My Linux Rig spoke to Christine Hall of FOSS Force about her "Linux rig" today and Bryan Lunduke had some thoughts on Canonical's collaboration myth. Dedoimedo reviewed GeckoLinux 421 and Gary Newell tested Peppermint 7 on his new Lenovo Ideapad.
  • After Multi-Month Tone Deaf Shitshow, Microsoft Finally Lets Users Control Obnoxious Windows 10 Upgrade
    Microsoft's decision to offer Windows 10 as a free upgrade to Windows 7 and Windows 8.1 made sense on its surface. It was a nice freebie for users happy to upgrade, and an effective way to herd customers on older Windows iterations onto the latest platform to help consolidate support expense. But Microsoft's upgrade in practice has seen no shortage of criticism from users annoyed by a total lack of control over the update, and Microsoft's violent tone deafness in response to the complaints. For example a Reddit post from an anti-poaching organization made the rounds earlier this year after the 17 GB automatic Windows 10 update resulted in huge per megabyte charges from their satellite broadband ISP. Microsoft's response to these complaints? Ignore them. As complaints grew, Microsoft finally provided a way to fully disable the forced upgrade, but made sure it involved forcing users to modify the registry, something Microsoft knew full well less technical users wouldn't be comfortable attempting to hurdle. [...] Things have been escalating ever since, often to comedic effect. But this week things changed somewhat with the news that Microsoft has struck a $10,000 settlement with a California woman who sued the company after an ill-timed Windows 10 upgrade brought her office computers to a crawl. The woman took Microsoft to court after support failed to help resolve the issue, a spokesman saying Microsoft halted its appeal of the ruling "to avoid the expense of further litigation."

  • The Linux Setup - Christine Hall, FOSS Force
    On my main desktop, I use Linux Mint 17.1, Rebecca. My main laptop, a 64-bit machine, is running Mint 17.2 Rafaela. The laptop got updated from Rebecca so I could write a review, but the desktop never got upgraded because it’s a 32-bit machine and would require another download, which I haven’t had the time to do. I have another laptop running Bodhi, which might be my favorite distro, but I can be more productive with Mint.
