Socionext shows their new SC2A11 ARMv8 server SoC featuring 24 ARM Cortex-A53 cores and their SC2A20 Interconnect bridge. SC2A11 is a highly integrated low-power server system suitable for edge computing which processes data at the edge of the cloud in the IoT era. Large amount of data can be processed faster in memory by adopting the 64bit ARMv8 architecture. Up to 1536 cores can be configured in a system for uses such as web serving, indexing, cloud computing.
Joakim Bech talks about Linaro's work in OP-TEE (Open Portable Trusted Execution Environment) small OS-like environment that sits aside a rich operating system, for instance Android. The purpose of the TEE is to keep all secret credentials and data manipulation in the small TEE rather than in a larger rich OS that is often the vulnerable target of malware and hackers in general. In order to reach this goal, application software is architected in a way such that sensitive functions are precisely defined and offloaded to the TEE in the form of Trusted Applications.
At Linaro Connect Budapest 2017, ARM and the Linaro LEG (Linaro Enterprise Group) team demonstrate Apache Ambari running on ARM servers. Apache Ambari is one of key Big Data components that provides an easy to use web interface to provision, manage and monitor Hadoop cluster and various other Big Data tools. In this demo Apache Ambari is running on 3 node cluster with Hadoop, YARN and Zookeeper, all on AARCH64 hardware.
With ARM servers getting into Datacenter, Linaro has been collaborating with ARM and ARM vendors in making sure Big data components work well in AARCH64 architecture. Porting and Building Apache Ambari on AARCH64 is one of the efforts the team has been working on apart from porting, building and benchmarking Hadoop, Spark, Hive, HBase and other Big data components. The team chose to showcase Apache Ambari as a high level component due to it being very intuitive, easy-to-use Hadoop management web UI backed by its RESTful APIs. Ambari provides a dashboard with metrics for CPU, Storage, memory utilization and also metrics for HDFS, MapReduce, Pig, Hive etc for monitoring Hadoop Cluster. It also provides step-by-step wizard for managing Hadoop Clusters (like adding nodes, taking down nodes, doing rolling upgrades, etc).
As of today, Ambari is officially supported only on X86 servers. The work team has done is to patch Ambari to work on AARCH64, which involved patching various dependencies like phantomjs, leveldb, leveldbjni java libaries, etc. Linaro is also part of ODPi organization (odpi.org), which has been working on standardizing Big Data. Ambari is part of ODPi's operations specs. The collaboration helps in speeding up upstreaming process since ODPi also has some of same maintainers as of ASF.
The work done for this demo is a PoC running in ARM lab (working on Linaro Dev Cloud at the mean time) and yet published.
This video features Eugene Xie ARM Principal Software Engineer & Tech lead of Workloads team of Enterprise Software, BSG, Ganesh Raju - Tech Lead, BigData team and Naresh Bhat, Cavium assignee to Linaro for BigData.
Arrow Dragonboard 820c Extended 96Boards, the Enterprise Edition Oxalis NXP ARMv8 Layerscape LS1012A
Arrow shows an early prototype of their upcoming Qualcomm Snapdragon 820 based extended edition 96Boards and they are showing their first Enterprise Edition 96Board named Oxalis. Based on NXPs latest ARMv8 Layerscape LS1012A Processor running at 800MHz, this board delivers up to date connectivity with two USB-3.0 ports, SATA, 2x Gigabit Ethernet and PCIe.
Arrow also has a whole bunch of other new development boards such as the Meercat, an i.MX7 based ARM Cortex-A7 board with ARM Cortex-M4 and the Chameleon, the first Intel / Altera FPGA based 96Boards. You can read Arrow's article about maker's experiences with the 96Boards here.
Also check back in the days to come as I will be filming Arrows presenting their latest 96Boards at the Embedded World in Nürnberg 14th-16th February, you can get your free pass here.
Robert Wolff featured in this video is the comunity manager at 96Boards hosting the weekly 96Boards Open Hours.
Rob Clark, maker of the open source GPU driver Freedreno shows off his latest Freedreno open source GPU working on an upcoming Qualcomm Snapdragon 820 based Dragonboard 820c development board, one that is going to use an expanded 96Boards specification to add PCI-E and Gigabit Ethernet ports among other things to the development board. This Freedreno and 820 board provides a significant jump in performance for the GPU, possibly 4x to 5x between the Adreno 306 in a Dragonboard 410c and the Adreno 530 in a Snapdragon 820 based board. The availability of the Freedreno open source GPU driver on Qualcomm based development boards means that these development boards can run all sorts of Linux distributions, including Debian, not just Android. You can read more about the Dragonboard 820c here.
The Linaro Digital Home Group (LHG) recognizes the need for automated video testing software in Linaro's automated validation architecture (LAVA). In LHG they have started looking at the open source Robot Framework generic test automation framework and OpenCV (Open Source Computer Vision). The demo at Connect (BUD17) shows some of the first steps of how to automate the verification of video playback using open source test projects that can be implemented as part of the Linaro Continuous Integration (CI) framework.
The Linaro Digital Home Group (LHG) has extensive experience working with the Comcast RDK. LHG has been instrumental in leading open source initiatives in the RDK. At Linaro Connect (BUD17), the LHG Director, Mark Gregotski, along with 2 Comcast assignee engineers (Siva Patchaiperumal and Kalyan Nagabhirava) are demonstrating a port of the RDK to the Qualcomm 96Boards Dragonboard 410c. This demo shows the RDK media framework taking advantage of the GStreamer-V4L2 support provided by the DBD410C to use the hardware video decoder. The HD video is scaled and then a rotating triangle is overlaid using the open source Freedreno graphics support available with DB410C. The demo shows smooth video playback without any stuttering with smooth graphics overlay. Since the video decode is offloaded to the video hardware, the CPU is not heavily loaded.
Interview with the core team behind the Linaro's AOSP TV project. The project lead Khasim Syed Mohammed and team members Show Liu and Vincent Chou demonstrate Android TV running on the 96Boards HiKey platform. The team shares the goals of the AOSP TV project, how it will benefit the SoC vendors, OEMs and ODMs of Smart TVs and Advanced Set-top box manufacturers and Android TV application developers. They clarify the project goal, its to create AOSP TV as the open source subset of Android TV and is not to fork the Android TV work from Google. They also share the details on upcoming LHG's AOSP TV m-lcr release, OPTEE security framework integration, DRM support to be added and a lot more.
Marc Moreno Berengue of ARM at Linaro Connect 2017 in Budapest shows TrustZone for ARM Cortex-M33 implementing a secure gateway between the Secure and Non-secure areas on the ARM Cortex-M33 SoC, with the ARM CoreLink SSE-200 subsystem, TrustZone, ARM CoreLink SIE-200, instruction cashes, power infrastructure components, Secure Debug with ARM CoreSight SoC, the optional ARM TrustZone CryptoCell and the optional ARM Cordio Radio. All these enabling security for IoT. This demonstration is running on the ARM Cortex-M Prototyping System (MPS2/MPS2+) which is a Versatile Express development board featuring a large FPGA for prototyping Cortex-M based designs and a range of different options for debug.
