While the binary wall has yet to fall with ARM SoC vendors in terms of providing open-source drivers -- namely when it comes to the graphics / multimedia blocks -- there's many active community projects for reverse-engineering these ARM blocks to provide open-source support. Here's another project that's being done for cracking the video decoder on a popular Chinese ARM SoC.
Version 1.0 has been reached for the cputemp utility that uses ACPI for monitoring the CPU temperature and providing various statistics under Linux.
Here are some more benchmarks of the ODROID-X, a $129 ARMv7 development board that packs four Cortex-A9 cores along with Mali-400 graphics to provide a fairly impressive punch. There's even some comparative numbers to a Sony PlayStation 3 running Linux.
Earlier today I published the long-awaited benchmarks of OS X 10.8 Mountain Lion vs. Ubuntu 12.04/12.10. The benchmarks showed strengths and weaknesses of both operating systems, resulting in the the usual spectrum of comments from Phoronix readers. Here now are the power consumption results when comparing OS X and Ubuntu Linux on Apple hardware.
Following the recent release of PowerTOP 2.1 I did some testing from a modern Intel notebook to see what kind of power-savings one can expect from running the open-source PowerTOP software on a modern notebook running Ubuntu.
Back in June there were Calxeda's ARM Highbank performance claims of delivering 15x performance-per-Watt superior performance to Intel's Xeon x86 processor. At long last, independent benchmarks of a quad-core Calxeda Highbank board are beginning to surface.
While Atheros network adapters were once notorious under Linux, their wired and wireless network adapters in recent years have been backed by permissively-licensed open-source drivers from the company. This work continues with Qualcomm Atheros announcing this week the release of a new ALX network driver.
While lately I've been busy with trying out the Retina MacBook Pro under Linux, which has been a big problem and I'm not recommending the rMBP for Linux users at this time (more details soon), it looks like the new MacBook Air might also have some Linux woes. Outside of Apple, the Sony Vaio Z Ivy Bridge laptop also has some Linux problems of its own.
While the Apple MacBook Pro with Retina Display is beautiful having a 15-inch display running at a resolution of 2880 x 1800 and 220 pixels-per-inch, Linux isn't ready for this high-performance, high pixel density notebook.
For those that missed it from Twitter this weekend, I was back on the Linux Action Show talking about, well, Linux.
Linux on the 2012 Apple MacBook Pro with Retina Display can cause some problems.
Hitting OpenBenchmarking.org this weekend are some interesting benchmarks comparing performance of AHCI vs. IDE modes under Linux from an AMD Fusion system.
When it comes to advancing Linux and open-source benchmarking, a number of breakthroughs are on the horizon with the Phoronix Test Suite and OpenBenchmarking.org.
For those interested in reverse-engineering USB keyboards (or other input devices), there's a short yet effective guide by Julien Danjou for reverse-engineering a Logitech keyboard in order to provide Linux support.
While Imagination Technologies has yet to change their stance on allowing open-source Linux graphics drivers or improving the quality of their closed-source Linux driver IP, they released two new GPUs today in the PowerVR line-up.
For those curious about the Linux performance on some modern ARM hardware like the Motorola Xoom or HTC Desire HD, here are some benchmarks comparing the performance of some ARM hardware compared to an Intel Atom, Intel Pentium, and AMD Athlon processors.
David Airlie has started out the week by putting out new releases for several of the vintage X.Org graphics drivers as well as publishing his very latest GPU hot-plug / PRIME stack, which is now 36 patches against the X.Org Server.
The latest milestone for Freedreno, the reverse-engineered open-source Qualcomm Adreno graphics processor found on their Snapdragon ARM SoC, is a spinning cube.
For those that missed it, the Green500 list was updated for June 2012. IBM's BlueGene/Q super-computer hardware dominates but there's a few surprises besides that.
If you happen to have about six projectors laying around, there's a new open-source project available that comes out of academia for panoramic multi-projector image rendering to have a panoramic visualization system for things like flight simulators and Google Earth.
If you've been wanting to share your iPad's Internet connection with your Linux system without resorting to jail-breaking your tablet or going through other lengthy steps, it should now be possible to setup.
As a follow-up to the Building A 96-Core Ubuntu ARM Solar-Powered Cluster, here's some videos and other information on this ~200 Watt ARM cluster that was running Ubuntu 12.04 and assembled out of 48 PandaBoards.
A few days ago when I shared the biggest problems with Linux as judged by the Phoronix community, at least a few people took issue with the fact that some of the ugly issues with Linux were pointed out.
Calxeda has put out its first benchmark of their forthcoming Calxeda ARM Server. The company is claiming a 15x performance-per-Watt advantage over a recent Intel Xeon CPU.
Since yesterday's keynote at the beginning of Apple's WWDC event where they announced several new MacBook products, I've received a number of emails asking about the Linux support for these 2012 MacBook Air models and the next-generation MacBook Pro.
Samsung Electronics has become a platinum sponsor of the Linux Foundation.
With the 8th birthday of Phoronix yesterday, here's a collection of the most popular Phoronix stories about Linux and open-source that were written since its creation in 2004.
After writing last month the open-source graphics card is dead and why the open-source graphics card failed, this weekend I received an email that begins with "Open Graphics! Here we go again! As our master thesis work we have implemented a open source graphics accelerator."
The UEFI SecureBoot saga for Linux continues with another update by Matthew Garrett of Red Hat.
Back in April I wrote about an open-source graphics driver for Qualcomm's Snapdragon. This reverse-engineered driver project was actually started by an employee of Texas Instruments -- a competitor to Qualcomm -- but was being done since it was some of the only ARM hardware out there where the developer wasn't tainted by NDAs. Since Phoronix delivered the announcement of this Snapdragon GPU driver, there hasn't been much news to report.
