We all want our devices to boot faster, but how much effort do you want to dedicate to optimizing and maintaining a custom kernel and apps? This presentation offers a graded list of things you can do to reduce boot time. They start with simple changes, such as adjusting the position of your main application the init sequence. Then there are the changes you can make to the kernel and bootloader configuration to speed things up, and finally, there are moderately advanced techniques such as using U-Boot in falcon mode.
All of this is done using standard configuration techniques, with the idea of being able to maintain these changes in the future. I will show the effect of each of these changes on typical a embedded dev board so that you can judge for yourself where on the journey you want to jump off.

Project Treble aims to modularize Android by moving hardware-related code out of the framework and into the vendor implementation. This allows for faster OTA updates by separating the framework updates from vendor updates. The key aspects of Treble include defining a vendor interface (VINTF), creating a vendor NDK (VNDK) for hardware abstraction, and requiring a vendor test suite (VTS) for quality control. The goals are to make the framework compatible across different vendor implementations and allow checking of compatibility between framework and vendor code.
This document summarizes the evolution of the RISC-V software ecosystem from 2015 to 2020. It describes how initial ports of key software in 2015, like GCC and Linux, have expanded to include upstream support in most open source software projects today. It outlines remaining priorities like completing support for specifications and filling gaps in programming language and application software support. The document concludes by encouraging continued collaboration to further mature the RISC-V software ecosystem.
Embedded Systems are basically Single Board Computers (SBCs) with limited and specific functional capabilities. All the components that make up a computer like the Microprocessor, Memory Unit, I/O Unit etc. are hosted on a single board. Their functionality is subject to constraints, and is embedded as a part of the complete device including the hardware, in contrast to the Desktop and Laptop computers which are essentially general purpose (Read more about what is embedded system). The software part of embedded systems used to be vendor specific instruction sets built in as firmware. However, drastic changes have been brought about in the last decade driven by the spurt in technology, and thankfully, the Moore’s Law. New, smaller, smarter, elegant but more powerful and resource hungry devices like Smart-phones, PDAs and cell-phones have forced the vendors to make a decision between hosting System Firmware or full-featured Operating Systems embedded with devices. The choice is often crucial and is decided by parameters like scope, future expansion plans, molecularity, scalability, cost etc. Most of these features being inbuilt into Operating Systems, hosting operating systems more than compensates the slightly higher cost overhead associated with them. Among various Embedded System Operating Systems like VxWorks, pSOS, QNX, Integrity, VRTX, Symbian OS, Windows CE and many other commercial and open-source varieties, Linux has exploded into the computing scene. Owing to its popularity and open source nature, Linux is evolving as an architecturally neutral OS, with reliable support for popular standards and features

The document summarizes key concepts about virtual memory from the 10th edition of the textbook "Operating System Concepts". It discusses how virtual memory allows processes to have a logical address space larger than physical memory by swapping pages between main memory and secondary storage as needed. When a process attempts to access a memory page not currently in RAM, a page fault occurs which is handled by the operating system by finding a free frame, loading the requested page, and resuming execution. Page replacement algorithms like FIFO are used when free frames are unavailable. Demand paging loads pages lazily on first access rather than up front.

How to Choose a Software Update Mechanism for Embedded Linux DevicesLeon Anavi
How to Choose a Software Update Mechanism for Embedded Linux Devices
by Leon Anavi, Konsulko Group
Embedded Linux Conference NA 2022 and Open Source Summit NA 2022
Atomic software system update of an embedded Linux device has always been an important part of any product, especially nowadays with the existing large fleets of connected devices and Internet of Things. There are several different widely used in the industry approaches: A/B updates with dual redundant scheme, delta updates, container-based updates and combined strategies. Open source technologies such as Mender, RAUC and libostree based solutions implement these strategies and provide tools to manage updates of multiple devices. What are the advantages and disadvantages? How to choose an appropriate open source solution for a specific project? This session explores a number of different open source Linux software update technologies with practical examples for integrating them using the Yocto Project and OpenEmbedded. In order to better understand the strengths and weaknesses of each technology, we deep dive in various use cases. The talk is appropriate for anyone with basic knowledge about Linux. It will hopefully help managers, engineers and developers better understand the technical challenges and the available open source solutions with which to overcome them easier and faster so that they can focus on the unique core features of their products.
Software update for IoT: the current state of playChris Simmonds

SR-IOV: The Key Enabling Technology for Fully Virtualized HPC ClustersGlenn K. Lockwood
How well does InfiniBand virtualized with SR-IOV really perform? SDSC carried out some initial application benchmarking studies and compared to the best-available commercial alternative to determine whether or not SR-IOV was a viable technology for closing the performance gap of virtualized HPC. The results were promising, and this technology will be used in Comet, SDSC's two-petaflop supercomputer being deployed in 2015.
Android provides concise logging and debugging capabilities. The boot process involves initializing hardware and loading drivers in the bootloader and kernel stages. The init process then sets up the file system and executes scripts to start services like the zygote process and boot animation. There are several Android logs including main, events, radio, and system. Tools like dumpsys and dumpstate provide detailed system status information. Native crashes produce a log with the build fingerprint, registers, stack trace, and current stack to aid in debugging.

This introduces the linaro OP-TEE project in the context of the Automotive Grade Linux distribution. This TEE is today considered as a potential key element to provides some security enforcement in the scope of Software OTA for the AGL distribution.
This brief slides set was presented during AGL Face to Face Technical Meeting 25 – 27 May, Vannes, France
Linux containers provide isolation between applications using namespaces and cgroups. While containers appear similar to VMs, they do not fully isolate applications and some security risks remain. To improve container security, Docker recommends: 1) not running containers as root, 2) dropping capabilities like CAP_SYS_ADMIN, 3) enabling user namespaces, and 4) using security modules like SELinux. However, containers cannot fully isolate applications that need full hardware or kernel access, so virtual machines may be needed in some cases.
This presentation is about a methodology which allows patching of a running Linux kernel, its technical details, limitations as well as kpatch tools.
The talk was delivered by Ruslan Bilovol (Associate Manager, Consultant, GlobalLogic) at GlobalLogic Embedded Career Day #2 on February 10, 2018.

[db tech showcase Tokyo 2016] E34: Oracle SE - RAC, HA and Standby are Still ...Insight Technology, Inc.
Standard Edition (SE) is alive and well – maybe it had some growing pains over the last year, BUT it is here to stay! SE is a powerful database albeit with some limitations. whether it is using a Cloud based environment or on premise. In this session we will discuss Oracle SE and review some of the recent changes and the introduction of the new kid on the block – Standard Edition 2 (SE2). Topics that will be discussed include moving between Editions, High Availability, Disaster Recovery as well as Backup and Recovery.
The document discusses how software-defined storage (SDS) is broken and proposes a solution to fix it. Specifically:
1. Standard SDS solutions are inefficient because they require similar hardware as dedicated systems and do not fully utilize modern processors and storage.
2. This inefficiency limits hardware choices and forces specialization, as different SDS solutions are needed for different workloads.
3. A new "holistic SDS" approach called StorONE aims to solve these problems by taking full advantage of hardware, requiring less resources than legacy systems, and providing a single environment for all workloads and protocols.
This document discusses changes to Hyper-V virtualization from Windows Server 2008 to 2012. Key changes include the ability to share virtual hard disks between VMs, improved quality of service controls, and more robust resource sharing between host and guest systems. The new features make Hyper-V more reliable and scalable for server virtualization needs over the next 2-3 years.
How to integrate OpenStack Swift to your "legacy" systemMasaaki Nakagawa
The document discusses two case studies of integrating OpenStack Swift object storage into legacy systems. Case 1 involves using Swift as backup storage for a legacy backup server. Issues arose due to the backup software not supporting Swift's REST API. Mounting Swift via Cloudfuse helped pass backups with workarounds. Case 2 uses Swift with a Cloud Storage Gateway (Fobas CSC) to provide a file server across locations, addressing Swift's lack of file protocols and small file performance. The combination met requirements and provided good performance. The document concludes cloud gateways can help integration but limit Swift benefits, and improving gateways and native cloud applications unlock more value.
The document summarizes a webinar about using accelerated file transfer software to solve challenges in live sports production. It discusses how transferring large video files over long distances can be slowed by network issues, and how file transfer acceleration technology addresses this by using UDP instead of TCP.

In this deck from the Rice Oil & Gas Conference, John Fragalla from Cray presents: Data Storage & I/O Performance: Solving I/O Slowdown: The "Noisy Neighbor" Problem
"In Oil and Gas, when using shared storage, mixed workloads can have a big impact on I/O performance causing considerable slowdown when running small I/O alongside large I/O on the same storage system. With the increase adoption of Flash, and new features in Lustre, such as Progressive File Layout (PFL) and Data on Metadata (DoM), Storage can be tuned to automatically isolate different workloads to different storage media to accelerate small I/O without disrupting large sequential I/O performance, using the right mix of Flash and Disk transparently. In this presentation, Cray will share real benchmark results on the impacts of the "Noisy Neighbor" application has on sequential I/O, and with the right storage tuning and flash capacity, how to optimize the storage to meet the demanding workloads of Oil and Gas to accelerate performance for a mixed workload environment."

Intorducing Big Data and Microsoft AzureKhalid Salama
The purpose of these slides is to give a high-level overview of Big Data concepts and techniques, as well as its related tools and technologies, focusing on Microsoft Azure. It starts by defining what Big Data is, as well as why Big Data platforms are needed. Fundamental components of a Big Data Platform are discussed, followed by a little bit of theory about Distributed Processing & CAP Theorem, and its relevance to how Big Data Solutions compare to Traditional RDBMS. Use case of how Big Data fits in Enterprise Data Platforms are shown. The Hadoop Ecosystem is briefly reviewed before Big Data on Microsoft Azure is discussed. Then some directions of How to get started with Big Data.
In this webinar join experts from Storage Switzerland and Tegile to discover if the All-Flash Data Center can become reality. We will explore the return on investment that All-Flash systems can deliver, like increase user and virtual machine densities, lower drive counts and simpler storage architectures. We will also look at some of the methods that All-Flash systems employ to deliver an acceptable cost per GB like thin provisioning, clones, deduplication and compression. Finally we will take one last look at disk, does it have a role in the All-Flash Data Center and if it does what should that role be?
This document provides an overview of Team Foundation, Microsoft's application lifecycle management tool. It discusses software configuration management and branches. It describes how developers can check code into the main branch, queue builds, and view build details. It also covers merging branches, searching code history, comparing builds, and shelving/unshelving code.
Scale up is history! is scale out the future for storageStarWind Software
This document discusses scale-out versus scale-up storage solutions. It begins by defining scale-out storage as using clusters of commodity hardware and software nodes, as opposed to scale-up which uses proprietary components in a single monolithic device. The document then covers benefits of scale-out like lower costs, simpler maintenance, and ability to non-disruptively scale capacity and performance. It also discusses potential issues and how to choose the right solution based on requirements. Example scale-out hardware and software vendors are provided.
The document discusses file splitting software that can split large files into smaller segments to allow for uploading or downloading of files when file size restrictions exist. It discusses how existing systems only support splitting some file types, while the proposed system would support splitting all file types like text, documents, images, audio, video and PDFs. The key modules of the proposed system are segmentation to determine segment sizes, file splitting to divide the file, and file joining to reassemble the original file from segments. A technical feasibility analysis is also provided that evaluates the required technologies and the organization's ability to support the system.
NVMe and all-flash systems can solve any performance, floor space and energy problems. At least this is the marketing message many vendors and analysts spread today – but actually, sounds too good to be true, right?
Like always in real life, there is no clear black or white, but some circumstances you should be aware of – especially if you intend to leverage these technologies.
You may ask yourself: Do I need to rip and replace my existing storage? What is the best way to integrate both? What benefits do I receive?
Well, just join our brief webinar, which also includes a live demo and audience Q&A so you can get the most out of these technologies, make your storage great again and discover:
• How to integrate Flash over NVMe in real life
• How to benefit of some Flash/NVMe for your entire applications
The document discusses techniques for compacting, compressing, and de-duplicating data in Domino applications to reduce storage usage and improve performance. It covers compacting databases, compressing design elements, documents, and attachments, using DAOS to store attachments externally, and tools for defragmenting files.

Git is a distributed version control system that allows developers to track changes to files over time. It stores snapshots of files and keeps track of file versions, reverting files back to previous states if needed. With Git, work can continue locally even when a server goes down. Some key aspects of Git include storing data as snapshots, having three main states for files (committed, modified, staged), and using branches to develop features separately from the master branch. Basic Git commands allow users to initialize repositories, add/commit changes, push/pull from remote repositories, switch/merge branches, and tag releases.
Are you struggling to fully realize the benefits of Git in your development processes? Watch this webinar to learn the benefits of using Git and how CollabNet’s TeamForge platform, training and services can help improve your Git adoption and performance throughout your global organization.
This document provides an overview of Jazz source control as implemented in IBM Rational Team Concert. It defines key concepts like repositories, workspaces, streams, components, and change sets. It describes how developers can create and manage local workspaces and change sets, share changes with their team through operations like deliver and accept, find and resolve conflicts, and preserve configurations using baselines and snapshots. The document also provides guidance on troubleshooting and discarding unwanted changes.
