Intel Beignet Is Working Out Surprisingly Well For OpenCL On Linux

Filed under
Graphics/Benchmarks
Linux
Hardware
OSS

Beignet is the project out of Intel's Open-Source Technology Center for exposing GPGPU/compute capabilities out of Ivy Bridge hardware and newer when using a fully open-source Linux stack. While Beignet differs greatly from Gallium3D's Clover state tracker, this Intel-specific open-source OpenCL implementation is working out quite well for Ubuntu Linux.

While I've been writing about Intel's Beignet project since early 2013, it's probably been about a year now since I tried out the code, which is developed by Intel's OTC graphics team in China. This weekend I tried out Beignet v0.9.2 as trying out the newest Intel OpenCL code has been on my TODO list for a while and it's been working out rather well in my initial tests.

Getting Involved With The New Raspberry Pi Graphics Driver

Filed under
Hardware

Eric Anholt, formerly a lead developer on Intel's Linux graphics driver, has been quickly working away at the VC4 Gallium3D driver and related code now being a Broadcom employee tasked with making an open-source driver for the Raspberry Pi. If you're looking to try out his in-development driver or help him out in the driver creation process, he's published a brief guide to lower the barrier to entry.

Eric published a blog post on Friday that covers the steps for building a Linux kernel that has the VC4 driver, building mainline Mesa with the VC4 driver, and also building Piglit for carrying out regression tests.

A New AMD Catalyst Linux Driver Unofficially Surfaces

Hardware

A German web-site is hosting a yet to be officially released Catalyst Linux driver.

As pointed out in our forums there is a new Catalyst Linux driver version that's being hosted by Computerbase.de. This driver is marked Catalyst 14.201.1008 and was uploaded today for Linux along with Windows.

While this driver should work for any supported hardware (Radeon HD 5000 series and newer), it's labeled amd-catalyst-desktop-apu-linux-x86-x86-64-14.201.1008.zip. The driver version number is higher than the previous publicly released Catalyst Linux build available from AMD's web-site.

MIPS tempts hackers with Raspbery Pi-like dev board

Hardware
OSS

Hard to choose between Raspberry Pi, BeagleBone Black, and MinnowBoard Max? Now there’s another choice: the open source MIPS-based “Creator CI20″ dev board.

In a bid to harness some of the energy and enthusiasm swirling around today’s open, hackable single board computers Imagination Technologies, licensor of the MIPS ISA, has unveiled the ISA’s counter to ARM’s popular Raspberry Pi and BeagleBone Black SBCs. These days, every processor vendor simply must have a community supported dev board in order to engage with the developer communities. (Incidentally, Intel’s is the MinnowBoard Max and AMD’s is the Gizmo.)

Device Tree Overlay Support Lands Upstream

Filed under
Linux
Hardware

Pantelis Antoniou originated device tree overlay support for the purpose of enabling dynamic hardware configuration under Linux on devices like BeagleBone that use device tree for hardware configuration. Device tree was introduced to Linux for the purpose of putting the description of hardware into data structures, rather than building it up programmatically, greatly reducing the amount of code required to be maintained within the Linux kernel sources. Until now, the device tree data structure was only processed at boot time and that simply can't work for devices that might change hardware configurations after boot. While many BeagleBone capes can be probed by the bootloader, a common use-case is hardware that is reconfigurable. The most obvious example is a cape with an FPGA on it.

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.

Chromebook to come with Intel Broadwell chips

Intel is expected to launch its 5th-gen Intel Core CPUs based on Broadwell architecture by the end of this year. According to the latest leaked information, Google’s Chromebook might feature this Broadwell chip. Intel is focusing on bringing high performance CPU which has minimum power requirement with Broadwell chip. Even though Broadwell is the scaled down version of Haswell, it will still maintain the same CPU performance as Haswell. The company is working on better performance-per-watt and lower power consumption to improve battery life of devices. Broadwell is just 14 nanometer in size. Read more

Quod Libet 3.2.1 Review – An Almost Perfect Music Player

It's a mystery why Quod Libet is not a more popular media player. It's been around for years and the developers have constantly worked on it. The last major update was done back in May 2014, and the software is stable and full of goodies. Quodlibet is a Latin phrase that means "what pleases" and it's used in music to describe a piece that's a combination of multiple melodies. The name seems to relate very well to the media player and it's actually quite catchy. Read more
