  • Linux on ARMIt's not even Friday yet, but there's more awkward entertainment today at the expense of Linux kernel trolls. The latest in the series of weird messages hitting the Linux kernel mailing list is a proposal to drop support for all CPU architectures but ARM and a new "invisible" file-system feature.

  • Linux on ARMThe latest Linux ARM benchmarks at Phoronix are comparing the performance of Gentoo Linux against Linaro 12.08 from a 1.4GHz quad-core ARM Cortex-A9 development board.
     

  • Linux on ARMHere's the latest benchmarks of the low-cost ODROID-X, a $129 quad-core ARM Cortex-A9 development board out of Korea with ARM Mali 400 graphics. For just $129 USD, the ODROID-X development board is very interesting with packing Samsung's quad-core Exynos 4412 ARM Cortex-A9 processors running at 1.4GHz per core, Mali-400 MP Core graphics, six USB 2.0 ports, 10/100 Ethernet, and support for running Android and/or Ubuntu/Linaro.

  • Linux on ARMHere's some interesting test results recently uploaded to OpenBenchmarking.org that compares the performance of ARM Cortex A8 and Cortex A9 cores running at 1.0GHz against an Intel Atom N450. All three systems running at 1.0GHz were also running Gentoo Linux. Clock-for-clock, can the latest-generation ARM Cortex-A9 take out the Intel Atom? For the most part, yes.

  • Linux on ARMHere 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.

  • Linux on ARMWhen it comes to operating systems for the TI OMAP4 PandaBoard and PandaBoard ES, Ubuntu Linux is usually the winner for several reasons. However, with last month's release of Fedora 17 for ARM, how is the Red Hat sponsored distribution running on these ARM development boards? 

  • Linux on ARMLast week I shared my plans to build a low-cost, 12-core, 30-watt ARMv7 cluster running Ubuntu Linux. The ARM cluster that is built around the PandaBoard ES development boards is now online and producing results... Quite surprising results actually for a low-power Cortex-A9 compute cluster. Results include performance-per-Watt comparisons to Intel Atom and Ivy Bridge processors along with AMD's Fusion APU.

  • Linux on ARMWhile comparing compiler performance of different Linux code compilers on different software stacks and hardware configurations is nothing new at all to Phoronix, usually it's done on x86 hardware. However, with ARM hardware becoming increasingly common and much more powerful, here's a comparison of the GCC and LLVM/Clang compilers on a dual-core ARM development board.

  • Linux on ARMIn recent weeks I have shown how Ubuntu 12.04 is ARM-ing up for better performance on the ARMv7 architecture by enabling hard-float builds and how the TI OMAP4 support has come together resulting in significant performance gains. Nevertheless, how is modern ARM hardware now comparing to the low-end Intel x86 competition? In this article are some results from Ubuntu 12.04 comparing the ARM performance to some Intel Core, Pentium, and Atom hardware.

  • Linux on ARMAs shared on Phoronix in many articles already, Canonical has big plans for Ubuntu in the ARM-space. They are looking forward to making Ubuntu Linux be the first operating system to support the forthcoming ARM Cortex A15, but before that and the other achievements they have planned, they must first ship Ubuntu 12.04 LTS.
