Linux on ARMNearly two months ago I wrote that a major open-source ARM announcement was coming. "This forthcoming announcement, which isn't being detailed yet but will be yet another Linux graphics exclusive for Phoronix the near future, is something entirely different from the other recent open-source ARM Linux graphics advancements" So what's the announcement?

Linux on ARMSummary: Linux founder Linus Torvalds, the founder and lead developer of Linux, has always been a man of few words and yesterday at LinuxCon 2012 he was no different. Still, the Linux creator hailed advances the kernel has made in the way of ARM support and power management, its progress on the cell phone front, and the fact that the kernel group has maintained its independence from manufacturers.

Linux on ARMFirst of all, this post is not about building an Angstrom distribution (Linux OS that is known to run well on embedded devices) from scratch. This about compiling a Linux kernel source which you can boot from using your Angstrom distro. I'm assuming that you already have a working Angstrom MMC with you. I used the one that came along with the BeagleBoard XM, pre-installed with Angstrom.

Linux on ARMWe've added support for the Nitrogen6X board from Boundary Devices, which features a 1GHz quad-core i.MX6 SoC. This board has a comparative wealth of connectivity to the other ARMv7 boards supported by Arch Linux ARM. Multiple display outputs, PCIe, SPI/I2C/GPIO, CAN, gigabit ethernet, and SATA are just some of the features available.

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 ARMThe Linux 3.5 kernel for Texas Instruments OMAP4 devices has finally been uploaded into the Quantal repository for Ubuntu 12.10. With the upgraded kernel release, here are some new benchmarks of the popular PandaBoard ES compared to earlier Ubuntu 12.10 development snapshots, Ubuntu 12.04 LTS, and Ubuntu 11.10 from the dual-core Cortex-A9 ARMv7 development hardware.

Linux on ARMSyracuse, NY and Pittsburgh, PA – August 23, 2012 – Critical Link (www.criticallink.com) and Timesys Corporation (www.timesys.com), today announced they are partnering to provide developers using the Critical Link MityARM-3359 System-on-Module (SoM) with an easy-to-use, affordable Linux software development framework that significantly speeds up time-to-market.

Linux on ARMMK802 is a popular ARM based super micro computer which can plug directly into any HDMI output for an on the go media player, internet browser, game machine or for general use. It features 1.0GHz Cortex-A8 CPU and 500MHz GPU, 1GB DDR3 memory and 4GB flash storage. The stock Android can be replaced with Ubuntu Linux.

Linux on ARMCanonical thinks that the ARM servers are the way of the future, and they are doing everything in their power to assure themselves that they're ready for the massive adoption of low-powered servers.

Linux on ARMWhile not as popular as NVIDIA's Tegra 3 ARM SoC, the Samsung Exynos 4412 quad-core ARM Cortex-A9 found on cheaply priced ODROID-X can actually outperform the quad-core NVIDIA ARM processor. Here are benchmarks of the $129 USD ODROID-X benchmarked against the NVIDIA Tegra 3 reference tablet and a PandaBoard ES running the Texas Instruments OMAP4460.

Linux on ARMThe Baserock™ Slab is a multi-processor server featuring 8 quad-core ARMv7-A CPUs running at 1.33GHz and an on-board high-speed network switch fabric with 5Gbit/s between the CPUs and 2x10Gbit/s external. Each compute node gets additional performance with its own dedicated low-latency mSATA solid state drive.

Linux on ARMThe ARMv8 64-bit architecture enablement, officially known as AArch64, is still ongoing for the Linux kernel. Back in early July were the initial Linux kernel patches for AArch64. The initial code drop consisted of about 23,000 lines of code to enable this 64-bit ARMv8 support in Linux. More on the AArch64/ARMv8 Linux enablement was talked about last month at Debian's DebConf 12.

Linux on ARMBack 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.

Linux on ARMNokia engineer Oleg Romashin has ported an early version of Firefox OS to run on the Raspberry Pi. Firefox OS is Mozilla's upcoming operating system for smartphones and tablets. Like Google Android, it uses a Linux kernel, but Firefox puts a heavy emphasis on the web — all the apps it runs are basically web apps.

Linux on ARMThere’s been a lot of good progress in the Xen on ARM with virtualisation extensions port since I first blogged about it here. Thanks to some recent work, mainly by Stefano Stabellini, we are now able to start our first guest domain, including paravirtual console disk and network devices!
