With the Linux 3.7 kernel there is now support for the SPARC-T4 processor that Oracle introduced last year.
The Freedreno reverse-engineered open-source ARM graphics driver continues to advance.
A university research director has shown that Apple's iPad 2 is as fast as the Cray-2 vector super-computer out of Cray Research from the 1980's. With some work to to the software, the iPad 2 performance benchmark result is quite impressive.
While Wacom tablets command most of the graphics tablet market-share, within the open-source Qt world it seems not many people actually care about these input devices. Wacom support -- after being pressed by many long-standing open bugs -- is being talked about for removal from Qt 5.0.
Matthew Garrett published the first patches this week that take an initial stab at the Linux kernel UEFI Secure Boot support.
There should be a PowerVR driver update soon-to-be-released that can handle kernel mode-setting (KMS) along with Mesa's Graphics Buffer Manager (GBM). With this support will also come the ability to run Wayland.
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.
