LAS16-405: OpenDataPlane: Software Defined Dataplane leader
Speakers: François-Frédéric Ozog
Date: September 29, 2016
★ Session Description ★
You may think OpenDataPlane and DPDK are somewhat equivalent. But they are not. OpenDataPlane is about Software Defined Dataplanes while DPDK is a Software Dataplane. A Software Defined Dataplane can control a hardware only Dataplane in a way that packets can go from input port to output port without reaching a CPU core. With Software Dataplanes , all packets have to reach a CPU core. As a result, one vendor could leverage a Software Defined Dataplane to build a 100Tbps network box while it is not possible with a Software Dataplane.

BKK16-103 OpenCSD - Open for Business!
The OpenCSD library for decoding CoreSight traces has reached the point where it is ready to be integrated into applications. This session will present an overview of the state of the library, its interfaces and explore and demonstrate a sample integration with perf.
Kernel Recipes 2016 - Upstream Kernel Graphics is (Finally) Winning
About 5 years ago I was at a big conference on the topic of what’s needed for upstream graphics. I spent a lot of time apologizing for and ranting about the various horror shows in the DRM graphics subsystems. And eventually some engineer from a hardware vendor asked:
“If this all such crap, why should we bother with upstream graphics?“
Now I can finally and honestly answer this, because upstream supports everything, has helpers for all possible and impossible display standards, is supported by ever Linux-based OS out there and every vendor has a driver. In this talk I will present about how we got there, and especially what’s been going on recently.

Chromium ppt
Chromium is a silvery transition metal that occurs naturally in ores like chromite. It has several important industrial uses including in stainless steel production and metal plating. Chromium exists in two main oxidation states, Cr3+ and Cr6+, with Cr6+ being more toxic and carcinogenic. Alternative plating methods are being developed to replace the use of hexavalent chromium due to its health and environmental risks.

Embedded Recipes 2018 - Upstream multimedia on amlogic so cs from fiction t...
Inexpensive set-top boxes are everywhere and many of them are powered by AmLogic SoCs. These chips provide 4K H.265/VP9 video decoding and as of the last couple years, have a very good Mainline Linux and U-Boot support.
Unfortunately, most of the multimedia features, like Hardware Accelerated OpenGL ES, Video Decoding, Audio Playback, and Video Rendering were missing from Upstream projects like Linux, Mesa, Gstreamer or FFmpeg. Thankfully a growing community of independent developers have managed to get most of these features to work using upstream only source code.
Maxime will present the challenges and benefits to have Multimedia support using upstream projects and will detail the technical challenges to offer a complete Multimedia support on these Amlogic SoCs.
The audience is anyone interested in ARM SoCs, multimedia, upstream development process or learning more about the architecture of the AmLogic application processors.
Attendees can expect a presentation on the actual work of code upstreamed for the Amlogic SoCs, a multimedia overview and challenges on non-x86 platforms, an overview of the hardware architecture, and much more.

Kernel Recipes 2014 - The Linux graphics stack and Nouveau driver
The Linux graphics stack is constantly evolving to add support for new hardware. This evolution and new software specifications have forced the X graphical server to be split into several components including a now rotates in the Linux kernel, the Direct Rendering Manager (DRM). A quick presentation of these components and their role will be carried out before looking at new major change in the common code, the NVIDIA Optimus technology.
One equipped with Optimus technology laptop has two graphics processing units (GPUs), one from Intel and one from NVIDIA. This technology combines the low power Intel GPU when the machine is not used to the performance of NVIDIA GPUs when the user plays. This technology, however, is a nightmare to manage kernel-side although the final building blocks necessary for its complete management are being finalized. Further explanation of this issue will be made and we’ll see how this new software architecture has added graphics acceleration on embedded processor SoCs like Tegra.
The case of open source NVIDIA driver, called “New” will then be studied. This is the graphics driver community as it is developed without the help of NVIDIA and attracted several regular contributors, including myself! We’ll take a quick history of the project before talking about the current developments and issues related to the lack of documentation.
The end of this presentation will then be left to the participants so they can ask more general questions about the graphics stack, if they wish.

ALSF13: Xen on ARM - Virtualization for the Automotive Industry - Stefano Sta...The Linux Foundation
During the last few months of 2011 the Xen Community started an effort to port Xen to ARMv7 with virtualization extensions, using the Cortex A15 processor as reference platform.
The new Xen port is exploiting this set of hardware capabilities to run guest VMs in the most efficient way possible while keeping the ARM specific changes to the hypervisor and the Linux kernel to a minimum. Developing the new port we took the chance to remove legacy concepts like PV or HVM guests and only support a single kind of guests that is comparable to "PVH" in the Xen X86 world.
Linux 3.7 was the first kernel release to run on Xen on ARM as Dom0 and DomU. Xen 4.3, out in July 2013, is the first hypervisor release to support ARMv7 with virtualization extensions and ARMv8.
This talk will explain why ARM virtualization is set to be increasingly relevant for the automotive industry in the coming years. We will go on to describe how Xen exploits the strengths of the hardware to meet the requirements of the industry. We will illustrate the early design choices and we will evaluate whether they were proven successful or a failure.Gnu linux on arm for $50 - $100

Woden 2: Developing a modern 3D graphics engine in Smalltalk
Tue, August 23, 2:30pm – 3:00pm
Youtube: https://youtu.be/fnPv7jtVY8U
First Name: Ronie
Last Name: Salgado
Email: roniesalg@gmail.com
Title: Woden 2: Developing a modern 3D graphics engine in Smalltalk.
Type: Talk
Abstract:
Developing a 3D graphics engine is hard. A 3D graphics engine has to be fast and has to be very flexible for being used in multiples projects. By writing
a graphics engine in Smalltalk, we gain a huge flexibility for free. However, Smalltalk is not a fast programming language as C++. Newer low-level
graphics APIs such as Vulkan, Direct3D 12 and Metal allows to communicate very fast with the graphics card by mapping memory buffers present in the
graphics processing unit in the CPU address space.
For Woden 2, we extended Smalltalk to get more performance in some critical sections, such as the math library. With these extensions we are able to write
directly to the graphics card memory and to avoid marshalling/unmarshalling overhead. We made an abstraction layer for low-level graphics APIs (Vulkan,
Direct3D 12 and Metal) in C that we are calling via FFI. For programming the GPU, we made a custom shader language with a compiler written in Smalltalk.
This custom shader language can be compiled into graphics API specific shader languages for being executed by the GPU.
This talk is about the challenges of the new architecture behind Woden 2, and about building an integrated environment for 3D graphics software
development.
Bio: Ronie Salgado is the main architect behind Woden, a 3D graphics engine that won the third place in ESUG 2014, 11th innovation technology awards.

Deep Learning Neural Network Acceleration at the Edge - Andrea Gallo
Short
The growing amount of data captured by sensors and the real time constraints imply that not only big data analytics but also Machine Learning (ML) inference shall be executed at the edge. The multiple options for neural network acceleration in Arm-based platforms provide an unprecedented opportunity for new intelligent devices. It also raises the risk of fragmentation and duplication of efforts when multiple frameworks shall support multiple accelerators.
Andrea Gallo, Linaro VP of Segment Groups, will summarise the existing NN frameworks, accelerator solutions, and will describe the efforts underway in the Arm ecosystem.
Abstract
The dramatically growing amount of data captured by sensors and the ever more stringent requirements for latency and real time constraints are paving the way for edge computing, and this implies that not only big data analytics but also Machine Learning (ML) inference shall be executed at the edge. The multiple options for neural network acceleration in recent Arm-based platforms provides an unprecedented opportunity for new intelligent devices with ML inference. It also raises the risk of fragmentation and duplication of efforts when multiple frameworks shall support multiple accelerators.
Andrea Gallo, Linaro VP of Segment Groups, will summarise the existing NN frameworks, model description formats, accelerator solutions, low cost development boards and will describe the efforts underway to identify the best technologies to improve the consolidation and enable the competitive innovative advantage from all vendors.
Audience
The session will be useful for executives to engineers. Executives will gain a deeper understanding of the issues and opportunities. Engineers at NN acceleration IP design houses will take away ideas for how to collaborate in the open source community on their area of expertise, how to evaluate the performance and accelerate multiple NN frameworks without modifying them for each new IP, whether it be targeting edge computing gateways, smart devices or simple microcontrollers.
Benefits to the Ecosystem
The AI deep learning neural network ecosystem is starting just now and it has similar implications with open source as GPU and video accelerators had in the early days with user space drivers, binary blobs, proprietary APIs and all possible ways to protect their IPs. The session will outline a proposal for a collaborative ecosystem effort to create a common framework to manage multiple NN accelerators while at the same time avoiding to modify deep learning frameworks with multiple forks.

Bud17 113: distribution ci using qemu and open qa
“Delivering a well working distribution is hard. There are a lot of different hardware platforms that need to be verified and the software stack is in a big flux during development phases. In rolling releases, this gets even worse, as nothing ever stands still. The only sane answer to that problem are working Continuous Integration tests. The SUSE way to check whether any change breaks normal distribution behavior is OpenQA. Using OpenQA we can automatically run tests that hard working QA people did manually in the old days. That way we have fast enough turnaround times to find and reject breaking changes This session shows how OpenQA works, what pitfalls we had to make ARM work with OpenQA and what we’re doing to improve it for ARM specific use cases.”

HKG18-501 - EAS on Common Kernel 4.14 and getting (much) closer to mainline
"Session ID: HKG18-501
Session Name: HKG18-501 - EAS on Common Kernel 4.14 and getting (much) closer to mainline
Speaker: Chris Redpath
Track: Mobile, Kernel
★ Session Summary ★
This session will introduce the changes to EAS planned for 4.14 kernel, and how Arm hopes that EAS will develop in future. EAS has already evolved from an Arm/Linaro joint project to involving a much wider community of SoC vendors, Google and interested device manufacturers. We will highlight the product-specific pieces remaining in the Android Common Kernel EAS implementation, and our plans to provide an upstreaming plan for each product feature. In particular, the new 'simplified energy model' is designed to provide mainline-friendliness and comparable performance using a simple DT expression of cpu power/performance.

HKG18-TR08 - Upstreaming SVE in QEMU
"Session ID: HKG18-TR08
Session Name: HKG18-TR08 - Upstreaming SVE in QEMU
Speaker: Alex Bennée,Richard Henderson
Track: Enterprise
★ Session Summary ★
ARM's Scalable Vector Extensions is an innovative solution to processing highly data parallel workloads. While several out-of-tree attempts at implementing SVE support for QEMU existed, we took a fundamentally different approach to solving key challenges and therefore pursued a from-scratch QEMU SVE implementation in Linaro. Our strategic choice was driven by several factors. First as an ""upstream first"" organisation we were focused on a solution that would be readily accepted by the upstream project. This entailed doing our development in the open on the project mailing lists where early feedback and community consensus can be reached.

HKG18-120 - Devicetree Schema Documentation and Validation
"Session ID: HKG18-120
Session Name: HKG18-120 - Structured Documentation and Validation for Device Tree
Speaker: Grant Likely
Track: Kernel
★ Session Summary ★
Devicetree has become the dominant hardware configuration language used when building embedded systems. Projects using Devicetree now include Linux, U-Boot, Android, FreeBSD, and Zephyr. However, it is notoriously difficult to write correct Devicetree data files. The dtc tools perform limited tests for valid data, and there there is not yet a way to add validity test for specific hardware descriptions. Neither is there a good way to document requirements for specific bindings. Work is underway to solve these problems. This session will present a proposal for adding Devicetree schema files to the Devicetree toolchain that can be used to both validate data and produce usable documentation.

HKG18-223 - Trusted FirmwareM: Trusted boot
"Session ID: HKG18-223
Session Name: HKG18-223 - Trusted Firmware M : Trusted Boot
Speaker: Tamas Ban
Track: LITE
★ Session Summary ★
An overview of the trusted boot concept and firmware update on the ARMv8-M based platform and how MCUBoot acts as a BL2 bootloader for TF-M.
Trusted Firmware M
In October 2017, Arm announced the vision of Platform Security Architecture (PSA) - a common framework to allow everyone in the IoT ecosystem to move forward with stronger, scalable security and greater confidence. There are three key stages to the Platform Security Architecture: Analysis, Architecture and Implementation which are described at https://developer.arm.com/products/architecture/platform-security-architecture.
_Trusted Firmware M, i.e. TF-M, is the Arm project to provide an open source reference implementation firmware that will conform to the PSA specification for M-Class devices. Early access to TF-M was released in December 2017 and it is being made public during Linaro Connect. The implementation should be considered a prototype until the PSA specifications reach release state and the code aligns._

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
