Freedreno ARM GPU Driver Keeps Hitting Milestones

The Freedreno open-source graphics driver project that's a clean-room reverse-engineered implementation of the Qualcomm Adreno graphics core on the company's ARM SoCs keeps reaching new milestones. While the driver is mostly just worked on by Rob Clark and without any support from Qualcomm, it's quickly becoming the flagship open-source ARM graphics driver for the Linux desktop.

IBM: Memory Power Management Savings Measurable

An IBM Linux Technology Center has shared that enabling experimental memory power management within the Linux kernel has dropped one of their test system's power consumption by about 2.6% but it's likely even more with experimental hardware.

OpenWFD: Open-Source WiFi Displays For Linux

David Herrmann, the open-source Linux graphics developer of fame for working to kill CONFIG_VT via work on numerous projects and many other open-source contributions, has started a new open-source project. Herrmann's latest initiative is OpenWFD, an open-source implementation of the WiFi Display Standard / Miracast.

It Looks Like The Open-Source GPU Will Fail Again

It looks like the latest attempt at producing an open-source graphics processor down to the hardware level -- an open-source FPGA GPU design -- will fail and not come to fruition with its targeted Kickstarter campaign.

OpenMoko Might Live On With N900 Phone Base

It's been a long time since hearing anything out of the OpenMoko camp, but Golden Delicious that worked on the GTA04 / OpenPhoneux is now trying for a new initiative. The company wants to develop the Neo900, which would be based around the once-popular Nokia N900 case but utilize upgraded internal components.

VIA Launches Its Own ARM Development Board

The latest company now offering low-cost ARM development boards for pushing their platform to ARM Linux and Android developers is VIA Technologies. VIA claims their new Springboard platform is "the fast path from prototype to production" and only costs $100 USD, but the specifications aren't all that impressive.

The ASUS "Bay Trail" T100 Is Not Linux Friendly

Last week I bought the ASUS Transformer Book T100TA, which is one of the first Intel "Bay Trail" devices in the United States. At a cost of $399 USD, it isn't as cheap as some Bay Trail devices talked up by Intel, but I was eager to see how the "Valley View" graphics would perform and all-around how this Atom SoC would run under Linux. Sadly, the ASUS T100TA appears to be a crap wreck at this point for running Linux.

ARM Cortex-A15 big.LITTLE Pitted Against Intel, AMD

Yesterday I began posting quad-core ARM Cortex-A15 SoC benchmarks using an ODRIOID-XU with Exynos 5 Octa, which has a quad-core Cortex-A15 paired with the "little" quad-core Cortex-A7. In this article are more benchmarks of the Samsung Exynos 5 Octa compared to various AMD and Intel CPUs.

ARM Cortex-A15 Quad-Core Linux ODROID-XU Tests

When the first ARM Cortex-A15 SoCs started rolling out in devices I found the dual-core A15 performance to be crazy fast for ARM and still find the Cortex-A15 performance to be great for low-power devices. Now, however, there's quad-core Cortex-A15 SoCs and even with the big.LITTLE architecture these four A15 cores can be paired with four A7 cores. In this article are our first benchmark results to share of a Samsung Exynos 5 Octa with a 1.6GHz Cortex-A15 configuration paired with a quad-core Cortex-A7 processor.

Linux Gets Extended Hardware Error Log Driver

A set of eight patches were published today for the Linux kernel that implement an extended hardware error log driver that provides enhanced Intel MCA event logging. With this driver, certain errors are more useful for users like being able to report the particular memory RAM DIMM where a memory corrected error happened and other detailed information not currently exposed via the Linux kernel.
