Radxa Rock2 RK3288 development board

Posted by – March 26, 2015

This is the Radxa Rock2 on Rockchip RK3288 quad-core ARM Cortex-A17, still being optimized for release at http://radxa.com/Rock2 it's configured as a SoM (System on Module) board with a choice of two base boards with more or less connectors and with that SoM module swappable. Tyler Baker of the Linaro LAVA team talks about the connectors and how Linaro is integrating this into http://kernelci.org which you can hear about at http://armdevices.net/2015/02/28/kernelci-org-upstream-kernel-validation-project/

Grant Likely, Linaro Fellow, talks ARM Linux Development

Posted by – March 26, 2015

Grant Likely is a Linaro Fellow, Linux kernel Device Tree maintainer and Chair of the Linux Foundation Technical Advisory Board. In this video he talks about the things Linaro has been doing to advance Linux on ARM and where he sees Linaro working towards in the future. They helped make big.LITTLE possible, they advance power/performance scheduling features around current and future ARM SoC designs to optimize the performance and power consumption for ARM Powered devices, from mobile to high-performance servers and networking.

ARM64 Open Laptop Project by Vero Apparatus

Posted by – March 26, 2015

Vero Apparatus is trying to design the worlds most powerful ARM Powered Laptop, powerful enough for software developers at Linaro to use ARM Laptops for their ARM related software development. The open source hardware and software will address the concerns that many people have about proprietary products, and provide the most transparent assurances about absence of security vulnerabilities.

The ARM64 Open Laptop concept was announced in an ad hoc session at DebConf 2014 in Portland, Oregon, where over a dozen interested developers gathered at fairly short notice. They approved the concept and decided on some of the things to do next. See the slides of the presentation

The idea is to produce a small quantity (say 100) of replacement motherboards physically compatible with a laptop model that is already popular with developers. Lenovo or HP might have suitable chassis models. The Lenovo X220 is a good candidate but Vero Apparatus is open to alternative proposals. The design will re-use an existing case, SATA drive, display, battery, keyboard, touchpad, webcam, speaker and microphone to reduce development cost.

The main processor will probably be an AMD Opteron A1100 system-on-chip code named "Seattle". In short, this has four or eight 64-bit Cortex-A57 cores, supports up to 128GB RAM, SATA and LAN. Being a server chip it lacks video, audio and USB, so either those must be added to the motherboard or another, more versatile chip must come along soon. Hardware choices will opt for longer battery life rather than 3D graphics performance.

Debian GNU/Linux is the default OS and distribution choice but Open Source implies freedom for the user. UEFI is the preferred firmware architecture, realistically in the form of Tianocore EDK2.

Qualcomm at Linaro Connect, Open Source Freedreno GPU Drivers for Qualcomm Adreno GPUs running on Inforce Computing’s Single-board-computers

Posted by – March 17, 2015

Hacking on Qualcomm Snapdragon 600 and Snapdragon 805 based Inforce Computing single-board-computers, Inforce 6410 and Inforce 6540, in this video, the Qualcomm Linaro Landing Team and Qualcomm Linaro engineers talk about the status of Ubuntu Linux release on Snapdragon 600 processor based development boards. Rob Clark, Freedreno project owner, talks about the status of open source graphics drivers for Qualcomm Adreno processor. The Linaro Linux release uses Freedreno graphics driver for HW acceleration. Other landing team engineers talk about various other plugins and drivers such Gstreamer plugin developed for the Linux release to enable to support for HW accelerated HTML5 video. There has been a lot of progress made on up streaming drivers for Snapdragon processors.

48-core 64bit Cavium ThunderX ARM Server demonstrating Virtualization

Posted by – February 24, 2015

Cavium is showing the most powerful ARM Processor in the world, with a 48-core ARMv8 64bit processor, demonstrating the high-performance visualization running the Xen Hypervisor running on an internal evaluation board and the KVM Hypervisor running on a rack-mounted 1U platform.

Google Project Ara development boards at Linaro Connect, Greybus status with Greg Kroah-Hartman

Posted by – February 22, 2015

Greg Kroah-Hartman shows the Google Project Ara prototype phone and development board, and he talks about Greybus the protocol that they are developing to make it possible for these hardware modules that must be able to talk to each other and to the host module, they can be hot swappable, they have to be able to describe themselves so everything just works smoothly, they work on the knowledge that they have from USB, PCI, Firewire and all the previous protocols that people have implemented, they work on the base level of what UniPro can do, and they go from there. This is just another sub-system of Linux that drivers plug into. Rob Herring is the project tech lead at Linaro for Project Ara, and he talks about how the Linaro guys are working on the Kernel portions, the ARM Applications Processor modules and the Android modifications to support hardware modules hotplug in a Smartphone.

Google Project Ara at Linaro Connect 2015

Posted by – February 21, 2015

Smartphone hardware modules Google Project Ara is being shown by Linaro CEO George Grey, as the modifications to Linux on ARM to support Project Ara are being developed and optimized together with Linaro engineers, many of the Google Project Ara engineers meet at the Linaro Connect conference to advance their development for the project. Linaro is one of many companies working for Google on Project Ara, focused on the firmware and on the software to make Android work with removable modules, to communicate through the UniPro bus for hardware modules. Linaro has a lot of experts in Linux and the Linux kernel, able to deliver what Google needs for this project.

ZTE ZX296702 Dual-core ARM Cortex-A9 for Set-top-boxes at Linaro Connect

Posted by – February 20, 2015

The Linaro ZTE Landing Team engineers talk about optimizing Android Kitkat boot time using TuxOnIce hibernation mechanism on ZTE SmartTV board. The net result is that it takes around 10 seconds to get into the Android home screen from a fresh power-on compared to the original over 30 seconds bootup time among other optimizations that they are doing for the ZTE Powered Set-top-box which is in millions of homes in China and around the world.
