Linux on ARM
Last March, the ARM Linux community got shaken by the complaints by Linus Torvalds for its lack of proper structure and organisation. This is totally true and mainly due to the large number of different SoC vendors, each one integrating the ARM IP's in a slightly different variant. Linaro immediately accepted the challenge to drive the kernel alignment of the ARM community and most ARM Linux experts got together and agreed on the way forward as early as May 2011 at the Developers' summit in Budapest.
This talk highlights the effort, subtleties and details involved in creating a common Power Management (PM) framework for ARM SMP Linux kernel. Since different ARM System on Chips (SoCs) are implementing PM management hardware in custom ways, the kernel has to adapt the PM framework to HW needs.
Five months ago I did a post announcing that we are working to bring Bodhi to ARM devices. I've been rather quiet about this part of our project since then. We are still finalizing the direction this part of our project is headed in, but for now we have landed on the choice of Debian Stable as our core. Our repository is currently online and you can easily install our Enlightenment packages on top of your Debian Stable ARM install by following these steps:
Steve Jobs was such a captivating promoter of inventions that his products reshaped our thinking, defining or redefining products we once thought we fully understood. At his best, Jobs was almost too good. If Picasso were God all fish would be flounders. But the computer industry, like nature, fosters diversity. Apple's smart clients, the iPhone and iPad, are iconic devices built around systems-on-a-chip (SoCs), but they are not the only important applications of this technology. Servers, too, can be made from compact, efficient, and inexpensive SoCs. And they will prove to be exceedingly disruptive.
This is a very early build (mostly a proof of concept) of Bodhi Linux for ARM running in a Debian Squeeze chroot on the Nokia N900. It is far from done, but that will change in the coming months. You can see from this video though the base functionality is there and the OS is snappy. Bodhi Linux is a minimalistic Linux distribution that utilizes the Enlightenment Desktop.
Even as x86 chipmakers like Intel Corp. (INTC) dream of getting a piece of lucrative smartphone and tablet chip market dominated by ARM Holdings plc (LON:ARM) licensees, ARM is ready to take the fight to Intel. Already preparing to invade the laptop space, courtesy of Microsoft Corp.'s (MSFT) incoming support with Windows 8, ARM has just taken a major step towards establishing a beachhead on Intel's most fertile and fast growing empire -- the server market.
It's no secret that ARM-based SoCs are advancing at an incredible rate compared to x86 CPUs. While ARM ratchets up the performance on the high end with multi-core architectures like the Cortex A9 and Cortex A15, which rivals and in many cases exceed the performance on low-power x86 chips, licensees such as TI have created full-featured SoCs at single-digit prices, enabling new low-power devices at tiny price points.
Earlier this year British games pioneer David Braben surprised many people with the first appearance of the Raspberry Pi, a low-cost, open source computer aimed at children that he was helping to develop.
After yesterday's announcement of HP's Project Moonshot, a programme that will accelerate the use of ARM low-power CPUs in data centers, Canonical also announced today that it will be involved in the Moonshot project.
BeagleBone, a miniature motherboard based on the ARM architecture, that will costs around $89 USD (65 EUR), has just been announced. BeagleBone is designed be installed in the BeagleBoard, a low-cost, fan-less single-board computer based on low-power Texas Instruments processors featuring the ARM Cortex-A series core.
Cellular network operator Vodacom recently launched a netbook, the Vodafone Webbook, that, at R1 499, it hopes will give South Africans an affordable entry into personal computing. TechCentral put the Webbook through its paces.
Kate Stewart announced on October 28th that thr Ubuntu 10.04 (Lucid Lynx) Netbook and ARM editions reached EOL (End of Life) on October 29th, 2011. The ARM and Netbook editions of Lucid Lynx were released 18 months ago, on April 29th, 2010. Since then, it received important security updates and critical fixes.
Applied Micro Showcases World’s First 64-bit ARMv8 Core at ARM Techcon 2011, Santa Clara California. The day ARM announced the first 64-bit ARMv8 instruction set architecture, AppliedMicro unveiled the launch of the industry’s first 64-bit ARM “Server-on-a-Chip” solution.
Ubuntu announced the 10.04 Netbook Edition and Ubuntu for ARM products 18 months ago, on April 29, 2010. At that time, Ubuntu committed to ongoing security and critical fixes for a period of 18 months for these specific products.
