Linaro 14.04 release is now available for download. See the detailed highlights of this release to get an overview of what has been accomplished by the Working Groups, Landing Teams and Platform Teams. The release details are linked from the Details column for each released artifact on the release information:
NetBSD - ARM multiprocessor support - - Those following the source-changes mailing list closely may have noticed several evbarm kernels getting "options MULTIPROCESSOR" in the last few days. This is due to...
AMD’s Big Bet on ARM Powered Servers: Opteron A1100 Revealed - - It has been a full seven months since AMD released detailed information about its Opteron A1100 server CPU, and twenty two months since announcement. Today, at the...
Red Hat Rolls Up Linux For ARM Servers - - The great thing about Linux is that it runs on nearly everything, and if ARM servers ever take off, they will do so because Linux workloads are ported from X86 and...
Linux on ARM
A 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.
There 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.
Yesterday 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:
The 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.
The latest illustration of software patents being bad and of pure silliness is a group of Chinese people trying to obtain a patent covering Wine on ARM for having the open-source program running Windows programs on the CPU architecture popular to smart-phones.
Back in September of last year after Apple unveiled the iPhone 5S smart-phone with a 64-bit processor, they said they would ultimately open-source their 64-bit ARM compiler back-end... A half-year later, we're finally seeing this code that yields another AArch64 back-end for LLVM.
Why 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!
Besides announcing the next-gen Pascal GPU family, NVIDIA just announced the Jetson TK1 DevKit... Already I have put in an order for this ARM development board with likely more on the way in being super-excited about the performance potential of this sub-$200 ARM Linux platform.
Avnet announced a COM based on Xilinx Zynq-7000 ARM/FPGA SoCs, and supported by an optional baseboard, power module, FPGA mezzanine card, and Linux BSP.
Jon Masters is responsible for leading research and development efforts around the ARM Architecture at Red Hat (in particular, the 64-bit ARM Architecture known as AArch64), instrumental in the creation of the Linaro Enterprise Group, sitting on the LEG Technical Steering Committee, and is elected to represent LEG on the core Linaro Technical Steering Committee.
In this video I go over how to install Linux Ubuntu onto a Google ChromeBook.
Debian developers are trying to land upstream support for 64-bit ARM (AArch64) in the Qt tool-kit.
Ukraine-based Evodbg announced an extremely small, Linux-ready COM based on Freescale’s i.MX287 ARM9 SoC, and matching the form-factor of a mini-PCIe card.
At least two companies have recently launched hosting services using dedicated ARM servers based on low cost development boards: NanoXion with its NX-BOX service powered by PiBox (Raspberry Pi) and CubieBox (Cubieboard 2) microservers, and miniNodes with servers based on Cubieboard2 first, then ODROID development boards, and possibly AllWinner OptimusBoard once/if it becomes available.
