While the Loongson MIPS64 CPUs have been available for a while now as a Linux-friendly chip, they are still tough to find in the western countries. New benchmarks reveal that the ARM SoCs are becoming a much more compelling offer for those caring about performance.
Over the past several weeks of running the Samsung Chromebook with its Exynos 5 Dual SoC that is comprised of an ARM Cortex-A15 dual-core processor, I've grown quite fond of this latest ARM processor.
MIPS Release 5 was announced today as a new MIPS processor architecture that encompasses MIPS32, MIPS64, and microMIPS instruction set architectures. MIPS "R5" brings in two years of work to deliver new processor features.
While there hasn't been much to report on with the open-source Freedreno driver in recent months -- a reverse-engineered attempt at creating a free 3D driver for Qualcomm's Adreno/Snapdragon graphics processor -- it's still being developed with new Git commits continuing to be common.
The PengPod tablet, which allows for dual-booting Google's Android and Ubuntu/Linaro on an ARM-based tablet, is becoming a reality after it was successfully crowd-funded.
In addition to the Samsung Exynos ARM SoCs being really attractive right now due to the impressive performance of the A15-based Exynos 5 Dual, the hardware is also nice for its open-source DRM graphics driver that keeps advancing.
While custom, unsigned code can be executed on the Microsoft Xbox 360 gaming console with Linux, kernel development in this area has been moving very slow.
It seems the binary curtain among ARM graphics vendors may finally be falling. Aside from NVIDIA contributing to the open-source Tegra DRM driver and other interesting actions recently in the ARM Linux space, Imagination Technologies may finally becoming more open. It's looking like there may be a surprise open-source play out of Imagination for PowerVR graphics in the near future.
After having a few more days to run and benchmark the Samsung Chromebook, it continues to be a very interesting notebook computer. For $250 USD this notebook packs a Samsung Exynos 5 Dual SoC, which bears a dual-core 1.7GHz ARMv7 Cortex-A15 processor and delivers rather good performance results. Here's some more performance numbers when loading up the Chromebook with Ubuntu Linux.
The Arndale Board is a dual-core ARMv7 development board built around the Exynos 5 Dual SoC, which features the new ARM Cortex-A15. As shown in yesterday's Samsung Chromebook benchmarks on Linux, the Exynos 5 Dual packs very good performance for being a low-power ARM chip.
It turns out that for at least one of Lenovo's computer models, their UEFI implementation is explicitly checking for Windows or Red Hat Enterprise Linux and refusing to boot the UEFI-installed system if neither operating system is reported.
With SuperComputing's SC12 conference kicking off today in Salt Lake City, AMD and NVIDIA have both come out with their new high-end GPU products for compute purposes.
Whenever writing about VIA Technologies on Phoronix, S3 Graphics always comes to mind due to its relations with HTC and VIA. In fact, it's the only time that S3 Graphics usually ever comes to my mind aside from when talking about S3 Texture Compression. Anyhow, after writing this morning about the VIA KMS driver still not being mainline, it's worth reminding uninformed Linux users that S3 Graphics products remain poorly supported under Linux.
This week marked the release of a new LM_Sensors user-space update.
MIPS Technologies has announced today that their patent portfolio is being bought out by a company largely backed by ARM while Imagination Technologies will be taking over the MIPS company.
After delivering some AMD Vishera multi-core scaling benchmarks for reference on Saturday, here's some similar tests conducted from a Calxeda ECX-1000 quad-core ARM server node.
Parallella is an attempt to make Linux parallel computing easier and is advertised as a "supercomputer for everyone", but will it come to fruition?
Rob Clark has provided a status update on Freedreno, his reverse-engineered ARM open-source graphics driver for the Qualcomm Snapdragon / Adreno hardware.
While the ultimate future of Texas Instruments' OMAP division remains uncertain, their software engineers continue to work on maturing the OMAP5 Linux support.
While it looked hopeful at first with today's announcement of a fully open-source graphics stack for the Broadcom VideoCore found in the popular Raspberry Pi development board, upon closer examination it's actually not that good.
The popular budget-friendly Raspberry Pi ARM development board now has a fully open-source graphics stack -- the user-space graphics drivers for the Broadcom VideoCore included!
One of few very technical and worthwhile sessions during the openSUSE Conference at this weekend's LinuxDays event was about porting Linux to new ARM-based hardware devices.
It appears that Samsung is preparing to open-source some code pertaining to their Exynos ARM SoC.
For those not over in the Czech Republic this weekend for the Linux events going on here, here are some more data points for the AMD A10-5800K "Trinity" APU to look at under Linux.
After yesterday publishing the first extensive benchmark results for the Calxeda EnergyCore ECX-1000 ARM Servers in the form of the 1.1GHz and 1.4GHz quad-core ARM Cortex-A9 nodes running Ubuntu 12.04 LTS and Ubuntu 12.10, here are more benchmarks to share today from the "5-Watt ARM Server" on Linux.
The Linux Foundation has shared their plan for how they intend to deal with UEFI SecureBoot for running Linux on PCs that have this Microsoft-pushed feature for trying to secure the system boot process.
A brief status report was shared concerning supporting the Consumer Electronics Control (CEC) feature of HDMI under Linux.
For several months there have been developers at Huawei and elsewhere working on an ACPI-based system device hot-plug framework for the Linux kernel.
Lemote has published new Linux kernel patches for enabling the Loongson-3 processor support plus Loongson-3 based systems.
