AMD “Bald Eagle” APUs target high-end embedded Linux

Hardware

AMD’s “Bald Eagle” R-Series processors offer four 3.6GHz “Steamroller” cores with Heterogeneous System Architecture support, plus Mentor Embedded Linux.

AMD has a dual-platform strategy for embedded: G-Series on the low end and R-Series on the high end. Now, the chipmaker has launched a second generation of AMD Embedded R-series processors in both CPU and APU (accelerated processing unit) variants, with the latter offering integrated, rather than optional discrete AMD Radeon graphics. AMD tipped its Bald Eagle R-Series processors last September, and has launched sales for five new variants. The new R-Series CPUs are designed for gaming machines, digital signage, medical imaging, industrial control and automation, and communications and networking infrastructure, says AMD.

Hardware
OSS

There’s a rash of open source hardware announcements today in advance of this weekend’s Maker Faire in San Mateo, California—and two are related to the popular Arduino microcontroller. While Arduino and its manufacturing partner Amtel are announcing Arduino Zero—a new high-end 32-bit version of the open-source microcontroller board—another Arduino partner is releasing a simplified version of the controller intended to make it easier for beginners to start prototyping devices with little or no knowledge of electronics.

Filed under
Hardware

Olimex has entered the computer-on-module market with three Linux- and Android-ready COMs, based on Allwinner’s A13 and A20 SoCs, and on TI’s AM3352.

In addition to selling oLinuXino branded open source single board computers based on Allwinner SoCs, such as the Allwinner A20-based A20-OLinuXino-Micro SBC, Bulgaria-based Olimex is now getting into computer-on-modules. Its first three COMs include.

Coreboot Keeps Getting Better Bay Trail Support

Filed under
Hardware

Coreboot for Intel's low-power Bay Trail platform is a basic DPTF framework. The DPTF framework for Bay Trail isn't yet complete but is nearly working. DPTF is the Dynamic Platform and Thermal Framework designed for "thin, quiet, and cool platform designs." As explained at 01.org, "Intel DPTF provides mechanisms for platform components and devices to be exposed to individual technologies in a consistent and modular fashion thus enabling a coordinated control of the platform to achieve the power and thermal management goals."

3D Printing's Success Points to a Rosy Future for Open Hardware

Filed under
Hardware
OSS

It's no secret that open source has shaken up the software world, not least for the savings it's brought both organizations and consumers. Now it's starting to look like open source hardware could have a similar, game-changing effect.

Though still nowhere near as ubiquitous as FOSS, open hardware is gaining ground rapidly -- especially with the booming popularity of open source 3D printing -- and some very compelling benefits are becoming clear.

Hardware

David has now posted working patches for his DP MST code on the DRI-devel mailing list. Right now his code has just been tested on a Lenovo Ultrabook boasting Intel "Haswell" graphics and it's working when connected to external hubs. There's still code that's a work in progress but overall it seems to be working fine. Right now this initial "preview code" works for Intel Haswell hardware with certain DP MST hubs.

No, ARM Didn't Open-Source Their Full Mali Linux Driver

Filed under
Linux
Hardware

A few links have been sent in to our news tip box with this page, which reads, "Open Source Mali-200/300/400/450 GPU Kernel Device Drivers." While the page mentions open-source drivers, it's only about the kernel portion of the driver and it's always been that way with ARM -- and most other ARM-based graphics vendors. The kernel portion is open, the user-space components are closed. Without an open user-space, having an open kernel driver is only of limited use, and will not be accepted into the upstream Linux kernel.

Kernel 3.18 development – the kernel column

Linus Torvalds announced Linux 3.17, the Shuffling Zombie Juror, saying, “The past week was fairly calm, and so I have no qualms about releasing 3.17 on the normal schedule”. The latest kernel includes a number of nice headline features, such as the new getrandom() system call and sealed files APIs that we covered in previous issues of LU&D. Linux 3.17 also includes support for less highlighted new features, such as new signature checking of kexec()’d kernel images and sparse files on Samba file systems (which is significant for those mounting Windows and Mac shares).

Weston's IVI Shell Sees New Version

There hasn't been much in the way of exciting Wayland/Weston developments to report on this month, but its development is continuing in its usual manner. Out today is another version of the Weston IVI Shell as it still works to being accepted upstream. The weston-ivi-shell is a reference shell for Wayland's Weston compositor running on In-Vehicle Infotainment (IVI) systems. The Weston-IVI work dates back many months and today's revision to the shell marks its eighth public version as it still seeks to be accepted into mainline Weston. Read more

Python 3 Support Added To The GNOME Shell

The GNOME Shell 3.15.2 release fixes some visual glitching, improves the layout of the extension installation dialog, supports the CSS margin property, and offers other bug fixes and minor enhancements. Most notable to GNOME Shell 3.15.2 though is there's finally Python 3 support. Many GNOME components have long ported their Python 2 code to Python 3 while GNOME Shell's Python support has just received the Py3 treatment. Details on GNOME's overall Python 3 porting work can be found via this Wiki page. Read more
