Kubernetes
by Ilya Dmitrichenko 30 Mar '18

30 Mar '18

Hi Folks, It's been a while since I posted here last time. I've not been involved with either hardware or embedded systems in general lately. I mostly work on cloud-native infrastructure, and the Kubernetes project. Kubernetes [1] is an open-source container orchestration system, and many people see it as the best abstraction and management layer for running applications in any cloud provider, and bare-metal or virtual machines. Kubernetes naturally allows clusters with any kind of hardware, as long as it can be used with Linux. In some cases certain applications benefit from certain hardware features. When user deploys an app [2] to a Kubernetes cluster, they can express an intention that certain apps have particular hardware needs, and they would do so by means of labels [3]. An example: you have some number of machines running Kubernetes. Some machines have faster storage then others, and a few have GPUs. You have apps that don't care where they run, but you also have apps that access data on disk very often, e.g. a database. You also a have apps that crunch data using GPUs. So you want to put these apps in the right places without having to care where exactly they run and get best utilisation you can out of hardware you have, in fully automated manner. Kubernetes will take care of this for you. Why could this be of interest? The most recent version of Kubernetes (v1.10) supports device plugins [4], which is a mechanism for making any kind of hardware discoverable and allocatable. If folks here are interested to hear more, I'm happy to connect in-person, or present at the meetup.

MicroZed board looking for good home
by Ilya Dmitrichenko 30 Mar '18

30 Mar '18

Hi Folks, I thought I'd post here before going to ebay. I have a brand new MicroZed board [1] that I bought a few years ago and never got a chance to use it. I'd be happy to give it to anyone interested for a reasonable offer. It's sold for $199 on avnet. I think it's still fairly modern and popular. I'm happy to take any offer from someone working on an open-source project, a student or for those who run community labs of some sort. As a bonus, I'd be happy to throw in a book by R. Sass and A. Schmidt, "Embedded Systems Design with Platform FPGAs: Principles and Practices" [2]. Which is a little older then the MicroZed board, but still is a very nice and valuable book. I've enjoyed reading it, but just don't get to do much of these things a present. I have other books I might put on Amazon, let me know if you are interested – I'd be happy for one person to take a whole package.

OSHUG 65 — Yanking the Chain: open source software compliance in the supply chain, Thursday 22nd March.
by Andrew Back 06 Feb '18

06 Feb '18

Hello, We have another 1-day event in March, which this time will be dedicated to the topic of open source software compliance, featuring talks and workshops on topics such as OpenChain, SW360 and FOSSology. There are additional sessions in the pipeline, but we were keen to get details out sooner rather than later, given this is a full day, now less than 2 months away, and diaries fill up quick. Further details will be provided in due course! Cheers, Andrew // OSHUG #65 — Yanking the Chain: open source software compliance in the supply chain On the 22 March 2018, 09:00 - 17:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/65 With the ever increasing complexity of embedded device software stacks, coupled with the proliferation of new mechanisms for distributing complex server software stacks, open source compliance has never been more important — or indeed more of a challenge. Fortunately, there are growing number of tools and methods at our disposal to support open source software compliance efforts. This 1-day event will feature talks and hands-on workshops covering a number of these, with insights into practical experiences and lessons learned. The preliminary programme can be found below and please note that further details will be published in due course as additional sessions are confirmed. ***Talks — Introducing OpenChain OpenChain is a scalable, flexible compliance programme, developed by the Linux Foundation. It provides a great foundation for businesses of all sizes to adopt appropriate practices and procedures in place to control development and supply chain risks. Already adopted by companies like Qualcomm, Toyota and ARM, it's equally applicable to SMEs. * Andrew Katz is a lawyer and former programmer who advises extensively on free and open source software and other opens. He is head of the technology department at Moorcrofts LLP, a boutique technology law firm, which is one of the 5 OpenChain pilot partners in the world, and has been involved in drafting many of the OpenChain materials. — Eclipse SW360 - Open Source Management with Open Source SW360 manages software components with their license compliance documentation in SPDX and allows for setting up bills-of-material to provide comprehensive documentation for products and projects. Organizations can use SW360 as a one-stop shop for sharing component information, tracking their usage in projects or products. This involves the handing of compliance information, but also, as an example, matching for vulnerabilities from data providers. As an EPL-1.0 licensed Open Source project, it is highly customizable, letting organizations keep their confidential product development data on premises, and prevents them from becoming dependent on a single vendor. This presentation shows briefly features and a walk through the application to demonstrate capabilities and use cases of SW360. * Michael C. Jaeger is one of the maintainers for the projects, FOSSology and SW360, both of which are in the area of license compliance and component management with open source software. At Siemens Corporate Technology in Munich, Germany, Michael manages the Siemens contributions to SW360 and FOSSology. Michael is a certified software architect and received a German PhD degree from the faculty of electrical engineering and computer science at TU Berlin. *** Workshops — Using FOSSology - License Analysis Hands On FOSSology is an open source license compliance software system and toolkit. As a toolkit, you can run license, copyright and export control scans from the command line. As a system, a database and Web user interface provide you with user interface and functionality to analyse the licensing situation of open source software. * Hosted by: Michael C. Jaeger. Note: Please aim to arrive by 08:45 as the workshop will start at 09:00 prompt. -- Andrew Back http://abopen.com

OSHUG 62 — RISC-V, RISC-V, RISC-V, Thursday 23rd November.
by Andrew Back 06 Nov '17

06 Nov '17

Hello, Details can be found below for the 62nd meeting. Best, Andrew // Event #62 — RISC-V, RISC-V, RISC-V On the 23 November 2017, 18:00 - 21:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/62 The sixty-second meeting will be on the theme of RISC-V, an open ISA which started life at the University of California, Berkeley. A joint meeting with the BCS Open Source Specialist Group. — Bringing up cycle-accurate models of RISC-V cores The openness of the RISC-V ISA has enabled the development of many open-source RISC-V cores with varying capabilities. Choosing an implementation that meets given requirements can be done to some extent by comparing specifications and other attributes of the cores, but any decision must be based on actual testing. Using Verilator to generate cycle-accurate models enables rapid development of testing platforms. This talk provides a report of our experience bringing up cycle-accurate models of two cores in particular, RI5CY from the PuLP project, and Clifford Wolf's PicoRV32. For testing, a software ecosystem consisting of a compiler, binary utilities, debugger, and an interface between the model and debugger accompanies the Verilator model. To compare the cores, we used the GCC test suite and the RISC-V ISA test suite for measuring correctness, and the Bristol/Embecosm Embedded Benchmark Suite (BEEBS) to compare performance. All code and scripts used for the implementation are open-source, and can be re-used by others who wish to do similar exercises with other RISC-V cores. * Edward Jones has a background in parsing techniques and works at Embecosm on LLVM and GNU toolchains. He is also involved in research by Embecosm to investigate ways in which the software tool chain can reduce program energy consumption. Edward Jones is a Computer Science graduate of the University of Kent. — FreeBSD/RISC-V and Device Drivers The FreeBSD port to RISC-V 64-bit ISA was added in January 2016. FreeBSD is the first operating system that officially supported RISC-V in the main repository. Since its introduction, support has evolved, RISC-V privileged architecture has updated a few times. The platform is maturing making it suitable for general, commercial, research and educational use. The GCC v7.0 target for RISC-V was officialy upstreamed and NVIDIA is planning to ship all of their GPUs with RISC-V coprocessor enabled in the future. Several companies have announced the start of RISC-V chip development and many universities are taking RISC-V as a target architecture for doing research. The world first RISC-V microcontroller-class board HiFive1 was released and we are getting closer to the first general purpose board to become available! This talk will describe the current status of FreeBSD/RISC-V, toolchain and supported simulators. The porting process as well as describing the latest changes made to FreeBSD in order to support the latest RISC-V privilege specification (v1.10). This includes enabling by default FDT support and drivers attachment change, SBI interface, compiler flags/built-in definition changes, support for updated BBL boot loader, RISC-V privilege levels, initial page tables build, page table entry flags and other changes. An overview of FreeBSD device drivers subsystem will also be covered describing the device frameworks, buses and kernel-interfaces that exists in FreeBSD (e.g. Newbus, cdevsw, bus_dma, SYSINIT, vt, sound, ifnet, spibus, etc), how to use and configure them and how to debug a device driver. This should answer the question: How to write device driver for FreeBSD/RISC-V? * Ruslan Bukin is a Research Associate at University of Cambridge Computer Laboratory. He has been a FreeBSD user since 2002 and src committer since 2013. His main interests and contributions to FreeBSD are related to computer architectures support, performance monitoring technologies support, hardware tracing technologies (Intel PT), devicedrivers, DMA engines and DMA frameworks, hardware security (Intel SGX, CHERI), heterogeneous computing. Ruslan is the lead developer of the FreeBSD/RISC-V project. He obtained a Computer Science degree in 2008 from Peoples' Friendship University of Russia in Moscow — Talk #3 TBA Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt.
