Fedora 21 Released For POWER & AArch64 Hardware

Filed under
Red Hat
Hardware

While Fedora 21 was officially released last week, coming out today is the release of Fedora 21 for the PowerPC and ARM AArch64 architectures.

Fedora 21 and its packages are now officially available for IBM POWER servers as the only PowerPC systems being officially supported by the PPC release. Support for Apple's older PowerPC systems is mentioned as a PPC platform that's most likely broken and will not be working out-of-the-box. Fedora for POWER in the 21 release offers an installer for the Fedora Server product, support for 32-bit Power has been dropped in favor of 64-bit, and there's numerous enhancements to Fedora on POWER compared to older releases.

Generic TrustZone Driver Proposed For Linux Kernel

Filed under
Hardware

ARM's security extensions are in the process of being bettered on Linux.

TrustZone is the marketing name for ARM's security extensions. TrustZone exposes two virtual processors with hardware access controls to let the application core switch between the two virtual states to avoid potentially leaking any information from one state/world to the other. TrustZone has been around going back to the ARMv6 days and there's been Linux support but it's largely been platform specific. Now, however, a generic TrustZone driver might finally come to the Linux kernel.

Is the ASRock Q1900DC-ITX Intel Motherboard a Good ARM SBC Alternative?

Filed under
Linux
Hardware

In the recent series on ARM single board computers I have covered the BeagleBone Black, MaRS, TI's OMAP5432 Board, the Radxa, a few of the ODroid ARM machines, and many more. On the Intel desktop side I've covered the NUC and MinnowBoard. I've learned that outright performance is faster on the Intel NUC than any ARM machine reviewed so far -- the tradeoff, of course, is cost. This time around we'll see whether the ASRock Q1900DC-ITX motherboard retains the high performance characteristic of an Intel board but also dips down to the low cost and lower power draw of the ARM world.

Eben Upton: Google’s Eric Schmidt helped inspire Raspberry Pi Model A+ price cut

Filed under

Hardware

While the Raspberry Pi has always been cheap, the Foundation didn’t rest on their laurels with the Model A+ price. In fact, Google’s Eric Schmidt had a hand in making it cheaper…
While it would have been the easiest thing in the world to continue selling the Raspberry Pi at the same price, the charitable foundation behind the credit card-sized PC made it even cheaper with the recent release of the Model A+. Why did they abandon their already impressive $25 price? Eben Upton explains:

AMD's HSA Run-Time Library Is Now Open-Source

Filed under
Hardware
OSS

Last week we reported on AMD's plans for a complete user-space open-source HSA stack. Today they have finally delivered!

The last remaining component,. the HSA run-time library was open-sourced this afternoon on GitHub. This HSA library goes with the AMD GPU LLVM back-end to form a complete user-space open-source driver stack for HSA applications using kernels written using OpenCL C99. This code goes along with AMD's new "AMDKFD" kernel HSA driver that's still in the process of being mainlined. The AMDKFD driver could potentially appear in the Linux 3.19 kernel but probably won't be merged before Linux 3.20 if going through the DRM subsystem pull.

Canonical’s “Snappy Ubuntu” Lands On AWS

Canonical’s stripped down “Snappy” edition of Ubuntu Core is now available on Amazon’s AWS cloud computing platform. If you’ve followed along over the last few weeks, that’s not a major surprise. Snappy first launched on Microsoft Azure at the beginning of this month and then arrived on Google’s Compute Engine platform earlier this week. It was pretty obvious that AWS’s EC2 would be next.

Public Interest, Software Freedom and Open Standards

...importance of working with upstream projects and initiatives for a government like the UK Government. [...] Public interest and software freedom are not always aligned, in the sense that software freedom grant rights to users of Free Software but does not imply users will get what they want; in this case however, these two notions could become very much aligned. The same holds true for Open Standards: if major chunks of the UK’s public sector’s pool of documents is migrated to ODF, there is something close to a liability – and an opportunity- for this Government to ensure the format continues to thrive and be improved.

Defending the Free Linux World

Co-opetition is a part of open source. The Open Invention Network model allows companies to decide where they will compete and where they will collaborate, explained OIN CEO Keith Bergelt. As open source evolved, "we had to create channels for collaboration. Otherwise, we would have hundreds of entities spending billions of dollars on the same technology." Read more
