Pidora 2014, an optimized Fedora Remix for Raspberry Pi, has been released by the CDOT team from Seneca College. Pidora 2014 is based on the latest build of Fedora for the ARMv6 architecture and includes packages from the Fedora 20 package set, although not all the packages have been implemented.

Linux on ARM
It 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.
This 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.
A few Phoronix readers have written in with excitement thinking in recent weeks - including this morning - that ARM open-sourced their Linux/Android graphics driver... But in reality, nothing has changed.
Here's our first public benchmarks of the NVIDIA Jetson TK1 ARM development board powered by the Tegra K1 SoC with quad-core+1 Cortex-A15 and NVIDIA Kepler GPU. There's also some thermal metrics for those concerned about the active-cooling on this development board.
Arch 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.
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:
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.
