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.

LAVA Lab to integrate HiKey from 96Boards.org

Posted by – February 18, 2015

The LAVA Lab is to integrate the Hisilicon Kirin 620 based 64bit HiKey board from http://96boards.org. Tyler Baker and Dave Pigott from the Linaro validation team discuss their plans for the deployment and testing of the HiKey board.

64bit HiKey Board selling at $129 through Arrow Electronics

Posted by – February 17, 2015

Arrow Electronics is the world's biggest distributor of electronics components, they are a supporting partner in the Hi-Key development board, supported by the new http://96Boards.org program. With experience in distributing many different previous developments like the TI based Beaglebone, Arrow is excited for the things to come in this space. This is the world’s first affordable 64bit ARM development board for software developers, makers, and OEMs. It comes with 4GB of eMMC, WiFi/BLE, and HDMI output. You can order yours today for $129 at https://parts.arrow.com/item/detail/circuitco/999-0005854#GenG

Hisilicon D02, 16-core ARM Cortex-A57 High Performance Board (32-core version coming next months!)

Posted by – February 15, 2015

Hisilicon engineer Justin Zhao, Software Architect at Hisilicon SoC architecture department, is bringing up the Linux software on the Hisilicon D02 Board, one of the most powerful ARM Processors in the world. They have a configuration with 32-core Cortex A57 @ max 2.1GHz and up to 2 SoC per board coming up within a few months (64-cores per board!), each SoC has 1MB L2 cache/cluser, 32MB L3 cache. The board has 12 SATA\SAS (8 for one SoC, 4 for the other), 2 10/100/1000Mb/s compatible Ethernet ports, 2 10Gb/s SFP+ Ethernet ports, 8 DDR3 RAM DIMMs, 4 PCIE solts (2 pieces/SoC), 2 UARTs & 2 JTAGs for debug, 1 USB host. Rob Savoye of Linaro's Toolchain Group joins in this video discussing the installation of the latest GCC to this Board. Justin Zhao shows how he can bootup from Sata, PXE, Provision mode, NFS, with OpenSuse 13.1, Ubuntu 14.04, working on Red Hat. A LAMP (LAVA) and lxc (container) have already been enabled, and some Benchmarks (e.g. perf, iperf, ltp) have been executed on it too, perhaps Hisilicon will soon publish the test results also.

96Boards Linaro Development Boards Initiative, $129 HiKey with Hisilicon 64bit Kirin620

Posted by – February 12, 2015

With the first being the Hislicon Kirin620 Octa Core ARM Cortex-A53 based $129 HiKey development board, http://96Boards.org is a new open hardware specification for ARM 32bit and 64bit development boards, and a Community Program for software delivery to developers, makers and OEMs. In this video, Linaro CEO George Grey describes the standardized expansion buses for peripheral I/O, display and cameras allowing the hardware ecosystem to develop a range of compatible add-on products that will work on any 96Boards product over the lifetime of the platform.The 96Boards initiative is designed to offer a single software and hardware community across multiple vendor boards supporting a range of different features. A fixed set of minimum functions including USB, SD, HDMI and standardized low speed and high speed peripheral connectors are provided. Vendors may add customized hardware and feature sets provided the minimum functions are available. Linaro expects this to extend the platform life, increase the market for add-on hardware, and accelerate open source upstreaming of support for new SoC features.

Here is the session by Linaro CEO George Grey talking further about the 96Boards hardware at Linaro Connect Hong Kong 2015:

Live Lava Lab demonstration, adding new development boards for automatic testing

Posted by – February 8, 2015

Showing how easy it is to integrate any development board in Lava. Beaglebone Black, Allwinner A20 Cubieboard2, IFC6410, Odroid-UX3 (Exynos5422). They can take any new board and just get it connected. LAVA is an automated validation architecture primarily aimed at testing deployments of systems based around the Linux kernel on ARM devices, specifically ARMv7 and later. The current range of boards (device types) supported by this LAVA instance can be seen on the scheduler status page https://validation.linaro.org/scheduler/ which includes details of how many boards of each type are available for tests and currently running jobs.

eInfochips enabling Linux support on ARM based SoCs

Posted by – February 8, 2015

They have enabled the Qualcomm Snapdragon APQ8064 (Snapdragon 600) with Linaro's Linaro OpenEmbedded based Ubuntu release. They have optimized it for video/audio capture encode/decode through software based encoding and optimizing HD resolution with hardware acceleration for video-chat.

Linaro Performance Contest, John Maddog Hall

Posted by – February 8, 2015

At http://performance.linaro.org/, in anticipation of ARM’s new 64-bit architecture, Linaro reviewed some of the source code of a typical GNU/Linux system and found over 1400 source code modules that included ARM assembly language which might need to be ported and does need to be tested to work on new ARM 64-bit processors (Aarch64).
Linaro also recognized that some of the modules were written a long time ago (by computer standards) when CPUs were single core and not multi-core, compilers were not as optimized and RAM memories were smaller and more expensive leading to trade-offs in portability and algorithm selection. In today’s era, it might be better to re-evaluate the use of assembly language and perhaps replace it completely with a higher-level language such as “C”. It might also be worthwhile to review algorithms that made sense in an earlier time, but have outlived their usefulness.
In some cases the assembly language that exists in the code was “transposed” from existing assembly language of a different architecture and did not necessarily utilize the best features of each assembly or machine language architecture. In other cases it might make more sense to create a compiler intrinsic to do certain functions such as identifying the architecture of the machine.
Finally, while the code in the modules may be very efficient and highly portable, the compiler invocations may need review to take advantage of new optimization switches.
All this amounts to a major opportunity to not only ensure GNU/Linux based systems will operate efficiently on new ARM 64-bit processors, but also to optimize the performance of these systems across architectures. In pursuit of this performance goal, Linaro decided to create a long-running performance contest directed at these modules, and in the future extend the contest to even more modules which may or may not have assembler language in them.
