BKK16-400A LuvOS and ACPI Compliance Testing
•
2 likes•755 views
ARM server hardware will be shipping in 2016. An incredible amount of work has been done to get this far -- defining and implementing industry standards used by servers, development and testing of SoCs, and all sorts of Linux kernel work. So, how do we make sure we meet all these industry standards? To a great extent, we've relied on magical thinking so far. That works, but only for so long. LuvOS and FWTS were created in order to catch many of the problems users have found; in this presentation, we describe how we have started extending FWTS to check for standards compliance, specifically ACPI and the SBBR, and how we can use LuvOS to run FWTS and other test suites so that we can rely on hard data, and not just wishful thinking.

BKK16-303 96Boards - TV Platform
This presentation provides the background for the requirements of the latest 96Boards TV Platform specification. It describes the range of set-top features that can be delivered and focuses on the key software and firmware support.
BKK16-410 SoC Idling & CPU Cluster PM
The linux kernel has two distinct ways of managing idle. The CPUidle framework for CPUs and for all other devices: runtime PM combined with generic power domains (genpd). In addition, CPUidle is not scaling well for multi-cluster SMP systems and heterogeneous systems like big.LITTLE. To better manage idle for modern SoCs with a hierarchical structure, we are exploring extending runtime PM and genpd to CPUs so there is a unified framework for managing idle across all devices.
BKK16-502 Suspend to Idle
Session will discuss the design and work done to get S2I working on the qualcomm 410c platform. In addition, session will provide the implementation details/requirements to support suspend to idle on ARM platforms.
Show performance numbers for latency and power consumption for S2I vs S2R (if available). Highlight possible improvements to decrease latency for S2I.
BKK16-213 Where's the Hardware?
Linaro has multiple labs and board farms with varying purposes. This session will start with an overview of each of these, their locations, their focus, etc. It will then provide examples and direction on how a Member can add their hardware to a board farm. It will also provide an overview of how a Member or employee can navigate/leverage/check out a board for experimentation and usage (this varies based upon which lab/board farm is being considered, so all will be reviewed) in each of the farm locations. Finally, the session will provide pointers to any respective documentation, user guides, etc. for each of the locations.
LAS16-200: SCMI - System Management and Control Interface
Title: SCMI - System Management and Control Interface
Abstract: In this session we present a new standard proposal for system control and management. The industry, both in high end mobile and enterprise, is trending towards the use of power and system controllers. In most cases the controllers have very similar communication mechanisms between application processors and controllers. In addition, these controllers generally provide very similar functions, e.g. DVFS, power domain management, sensor management. This standard proposal provides an extensible, OS agnostic, and virtualizable interface to access these functions.

BKK16-308 The tool called Auto-Tuned Optimization System (ATOS)
ATOS is an Auto Tuning Optimization System that is able to find automatically the best performance/size tradeoff from a build system and a training application. The input of ATOS tools are a build command and a run command. From the build command, ATOS will infer an internal build configuration that it will run with different sets of compiler options. These build configurations are executed with the run command from which code size and performance will be extracted.
From the set of build configurations that ATOS explores, one can extract the preferred trade-off between code size and performance. The extracted build configuration can be archived and replayed later in order to generate the optimized executable without any modification into the initial build system.
The nice property of ATOS is that NO modification of the sources or the makefiles are needed. ATOS can work on any large/deep project, as soon as the compiler used is gcc or LLVM under Linux.

LAS16-500: The Rise and Fall of Assembler and the VGIC from Hell
Speakers: Marc Zyngier, Christoffer Dall
Date: September 30, 2016
★ Session Description ★
KVM/ARM has grown up. While the initial implementation of virtualization support for ARM processors in Linux was a quality upstream software project, there were initial design decisions simply not suitable for a long-term maintained hypervisor code base. For example, the way KVM/ARM utilized the hardware support for virtualization, was by running a ‘switching’ layer of code in EL2, purely written in assembly. This was a reasonable design decision in the initial implementation, as the switching layer only had to do one thing: Switch between a VM and the host. But as we began to optimize the implementation, add support for ARMv8.1 and VHE, and added features such as debugging support, we had to move to a more integrated approach, writing the switching logic in C code as well. As another example, the support for virtual interrupts, famously known as the VGIC, was designed with a focus on optimizing MMIO operations. As it turns out, MMIO operations is a less important and infrequent operation on the GIC, and the design had some serious negative consequences for supporting other state transitions for virtual interrupts and had negative performance implications. Therefore, we completely redesigned the VGIC support, and implemented the whole thing from scratch as a team effort, with a very promising result, upstream since Linux v4.7. In this talk we will cover the evolution of this software project and give an overview of the state of the project as it is today.

★ Session Description ★
The CoreSight framework available in the Linux kernel has recently been integrated with the standard Perf trace system, making HW assisted tracing on ARM systems accessible to developers working on a wide spectrum of products. This presentation will start by giving a brief overview of the CoreSight technology itself before presenting the current solution, from trace collection in kernel space to off system trace decoding. To help with the latter part the Open CoreSight Decoding Library (openCSD) is introduced. OpenCSD is an open source library assisting with the decoding of collected trace data. We will see how it is used with the existing perf tools to provide an end-to-end solution for CoreSight trace decoding. The presentation will conclude with trace acquisition and decoding scenarios, along with tips on how to interpret trace information rendered by the perf tools.

This document discusses challenges in system-on-chip (SoC) architectures and proposes using existing Linux frameworks to manage network-on-chip (NoC) interconnects. It outlines using the consumer-provider model to represent NoCs, describing topologies and endpoints in device trees, setting constraints between devices with PMQoS, and triggering updates through runtime power management. The goal is to leverage existing Linux infrastructure for controlling NoCs and improving performance, predictability and quality of service.

★ Session Description ★
In computer/mobile product world, due to the stability, project timeline, etc considerations, latest upstream kernel isn’t their preference. The long term stable kernel is. But if you want to some of the latest features which only is in upstream kernel,you will have to backport them to old stable kernel. This presentation will share the kernel feature backport experience with audience, help them understand how to do backports quickly and effectively without detailed knowledge of the target feature, thus giving more flexibility and Improving productivity when making products. We will use some examples, to discuss how to get info from backport request, how to find necessary commits, how to get dependency, how to resolve conflicts, and finally how to test it.

LAS16-101: Efficient kernel backporting
LAS16-101: Efficient kernel backporting
Speakers: Alex Shi
Date: September 26, 2016
★ Session Description ★
In computer/mobile product world, due to the stability, project timeline, etc considerations, latest upstream kernel isn’t their preference. The long term stable kernel is. But if you want to some of the latest features which only is in upstream kernel,you will have to backport them to old stable kernel. This presentation will share the kernel feature backport experience with audience, help them understand how to do backports quickly and effectively without detailed knowledge of the target feature, thus giving more flexibility and Improving productivity when making products. We will use some examples, to discuss how to get info from backport request, how to find necessary commits, how to get dependency, how to resolve conflicts, and finally how to test it.

HKG15-300: Art's Quick Compiler: An unofficial overview
---------------------------------------------------
Speaker: Matteo Franchin
Date: February 11, 2015
---------------------------------------------------
★ Session Summary ★
One of the important technical novelties introduced with the recent release of Android Lollipop is the replacement of Dalvik, the VM which was used to execute the bytecode produced from Java apps, with ART, a new Android Run-Time. One interesting aspect in this upgrade is that the use of Just-In-Time compilation was abandoned in favour of Ahead-Of-Time compilation. This delivers better performance [1], also leaving a good margin for future improvements. ART was designed to support multiple compilers. The compiler that shipped with Android Lollipop is called the “Quick Compiler”. This is simple, fast, and is derived from Dalvik’s JIT compiler. In 2014 our team at ARM worked in collaboration with Google to extend ART and its Quick Compiler to add support for 64-bit and for the A64 instruction set. These efforts culminated with the recent release of the Nexus 9 tablet, the first 64-bit Android product to hit the market. Despite Google’s intention of replacing the Quick Compiler with the so-called “Optimizing Compiler”, the job for the the Quick Compiler is not yet over. Indeed, the Quick Compiler will remain the only usable compiler in Android Lollipop. Therefore, all competing parties in the Android ecosystem have a huge interest in investigating and improving this component, which will very likely be one of the battlegrounds in the Android benchmark wars of 2015. This talk aims to give an unofficial overview of ART’s Quick compiler. It will first focus on the internal organisation of the compiler, adopting the point of view of a developer who is interested in understanding its limitations and strengths. The talk will then move to exploring the output produced by the compiler, discussing possible strategies for improving the generated code, while keeping in mind that this component may have a limited life-span, and that any long-term work would be better directed towards the Optimizing Compiler.

44CON 2014 - Stupid PCIe Tricks, Joe Fitzpatrick
Joe FitzPatrick gave a presentation on exploiting PCIe (Peripheral Component Interconnect Express) buses for hardware attacks. He discussed using DMA (direct memory access) over PCIe to read and write system memory, modify firmware, and potentially bypass mitigations like IOMMU (input-output memory management unit). FitzPatrick demonstrated proof-of-concept attacks on Macs and Windows PCs using custom PCIe devices and software. However, he noted that fully bypassing protections like VT-d on Macbooks had not yet been achieved and more work is needed to build attacks without imitating a genuine device.

Exploring Compiler Optimization Opportunities for the OpenMP 4.x Accelerator...
Third Workshop on Accelerator Programming Using Directives (WACCPD2016, co-located with SC16)
While GPUs are increasingly popular for high-performance
computing, optimizing the performance of GPU programs is a time-consuming and non-trivial process in general. This complexity stems from the low abstraction level of standard
GPU programming models such as CUDA and OpenCL:
programmers are required to orchestrate low-level operations
in order to exploit the full capability of GPUs. In terms of
software productivity and portability, a more attractive approach
would be to facilitate GPU programming by providing high-level
abstractions for expressing parallel algorithms.
OpenMP is a directive-based shared memory parallel programming model and has been widely used for many years.
From OpenMP 4.0 onwards, GPU platforms are supported
by extending OpenMP’s high-level parallel abstractions with
accelerator programming. This extension allows programmers to
write GPU programs in standard C/C++ or Fortran languages,
without exposing too many details of GPU architectures.
However, such high-level parallel programming strategies generally impose additional program optimizations on compilers,
which could result in lower performance than fully hand-tuned
code with low-level programming models.To study potential
performance improvements by compiling and optimizing high-level GPU programs, in this paper, we 1) evaluate a set of
OpenMP 4.x benchmarks on an IBM POWER8 and NVIDIA
Tesla GPU platform and 2) conduct a comparable performance
analysis among hand-written CUDA and automatically-generated
GPU programs by the IBM XL and clang/LLVM compilers.

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.”

Talk Title: OpenHPC Automation with Ansible
Talk Abstract: "In order to test OpenHPC packages and components and to use it as a
platform to benchmark HPC applications, Linaro is developing an automated deployment strategy, using Ansible, Mr-Provisioner and Jenkins, to install the
OS, OpenHPC and prepare the environment on varied architectures (Arm, x86). This work is meant to replace the existing ageing Bash-based recipes upstream while still keeping the documents intact. Our aim is to make it easier to vary hardware configuration, allow for different provisioning techniques and mix internal infrastructure logic to different labs, while still using the same recipes. We hope this will help more people use OpenHPC with a better out-of-the-box experience and with more robust results"

Talk Title: HPC network stack on ARM
Talk Abstract:
Applications, programming languages, and libraries that leverage sophisticated network hardware capabilities have a natural advantage when used in today¹s and tomorrow's high-performance and data center computer environments. Modern RDMA based network interconnects provides incredibly rich functionality (RDMA, Atomics, OS-bypass, etc.) that enable low-latency and high-bandwidth communication services. The functionality is supported by a variety of interconnect technologies such as InfiniBand, RoCE, iWARP, Intel OPA, Cray¹s Aries/Gemini, and others. Over the last decade, the HPC community has developed variety user/kernel level protocols and libraries that enable a variety of high-performance applications over RDMA interconnects including MPI, SHMEM, UPC, etc. With the emerging availability HPC solutions based on ARM CPU architecture it is important to understand how ARM integrates with the RDMA hardware and HPC network software stack. In this talk, we will overview ARM architecture and system software stack, including MPI runtimes, OpenSHMEM, and OpenUCX.

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.

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._

Introduction of Cybersecurity with OSS at Code Europe 2024
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
"Choosing proper type of scaling", Olena Syrota
Imagine an IoT processing system that is already quite mature and production-ready and for which client coverage is growing and scaling and performance aspects are life and death questions. The system has Redis, MongoDB, and stream processing based on ksqldb. In this talk, firstly, we will analyze scaling approaches and then select the proper ones for our system.
Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Which one is cheapest? Which one is fastest? Which one will scale to meet our needs?
Join me in this session as we dive into each AWS hosting service to determine which one is best for your scenario and explain why!
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.
