Why ARM Servers, And Why Now?

how-toIt is a pity that smartphones and tablets did not come along earlier and did not need 64-bit processing and memory addressing sooner than they did. Had these consumer devices (which are now generally thought of as being indispensable for business as well) required such rich circuitry earlier, then the collective of chip manufacturers who are part of the ARM collective might have put some server-class chips into the field a lot earlier and given datacenters some real alternatives to the X86 architecture by now.

NVIDIA Tegra K1 Compared To AMD AM1 APUs

Linux on ARMThis weekend when publishing preview benchmarks of NVIDIA's Tegra K1 from the Jetson TK1 development board, there were numerous requests by Phoronix readers to see this high-end ARM SoC pitted against the new AMD AM1 APUs. In this article are some benchmarks of Ubuntu 14.04 LTS on all of the AM1 Athlon and Sempron APUs compared to the Tegra K1 Cortex-A15 SoC.

Enabling Arch Linux ARM on Springboard

Linux on ARMArch Linux is my favorite Linux distribution of the half the dozen I've used. It has cutting edge packages, a rolling release (instead of fixed releases it keeps everything always up to date), the best package manager I've seen (pacman), an amazing community & wiki -- and also ARM support. This last point does matters for Springboard and is the main topic of this post.

A survey of ARM operating systems

Linux on ARMA piece of hardware without the software to run on it does not do much good. I can have the best piece of computing equipment if there's no operating system to boot it. With all their advantages, each ARM CPU still requires some effort on the side of operating system maintainers before the hardware and software can work well together. Fortunately there's a very active community, lots of accumulated developer knowledge, and many choices.

How to set up a lightweight web server on Raspberry Pi

Linux on ARMThere are a variety of web server software available for Linux-based platforms including Raspbian. Using one of those available web server software, we can turn Raspberry Pi into a 24/7 available portable web server. In this case, however, we must understand that Raspberry Pi has hardware limitations in terms of CPU clock speed, memory, etc. As such, we want to avoid running resource-heavy software (e.g., Apache) on Raspberry Pi.

Fedora 21 To Evaluate Remote Journal Logging, 64-bit ARM Emulation

Linux on ARMYesterday on Phoronix we covered 12 new feature proposals for Fedora 21 and following that story yesterday were a handful of new feature proposals for this next major Fedora release. On top of the features already approved, the features talked about yesterday and last week's approved features, a few more proposals were sent in yesterday for the approval by the Fedora Engineering and Steering Committee (FESCo) this week. These very latest proposals include:

Linux 3.14 kernel revision beefs up ARM, VM support

Linux on ARMThe latest Linux kernel's revision number may be 3.14, but don't expect any pi jokes in the release notes. Do, however, look past the matter-of-fact release announcement on the Linux kernel development mailing list for some intriguing improvements in ways that may have implications for cutting-edge processors and for cloud/VM environments.

Porting to 64-bit ARM

Linux on ARMWhy 64-bit? It seems that is a question with many answers! For some, it will be the need to address more than 2GB or 4GB of memory, for others the need for wider registers and greater accuracy of 64-bit data processing, for still others the attraction of a larger register set. Either way, the 64-bit train is gathering speed and if you don't get on board it may leave you behind!
