Embedded recipes 2018 - End-to-end software production for embedded - Guy Lun...Anne Nicolas
At this point, anyone can put a quick GNU/Linux distro together to test on almost any device. The tooling has been greatly simplified and the hardware enablement has come a long way. So why do we need this talk? Quite literally for the mountain of challenges that unfortunately get completely eclipsed by the mirage of these one-time build and forget environments and tools that everyone tickers with nowadays. Being able to produce solid repeatable results does not mean being able to run the same scripts more than once but rather a true complete Continuous Integration solution accounting for all aspects of the new product. This talk will discuss actual situations experienced by Collabora and will open the discussion for others to share and contribute.

LAS16-309: Server Ecosystem: Xen on ARM, from Big Iron to IoT & LuaJIT status on Aarch64
Speakers: Ryan Arnold, Steve Capper, Julien Grall, Zheng Xu
Date: September 28, 2016
★ Session Description ★
Abstract Xen on ARM: The Xen port is exploiting this set of new hardware capabilities to run guest VMs in the most efficient way possible while keeping ARM specific changes to Xen and Linux to a minimum. ARM virtualization is set to be increasingly relevant for the embedded industry in the coming years.
Whilst Xen is best known as the technology powering the biggest clouds in the industry, it also a great fit for automotive deployments and mobile devices that can fit in your pocket. The talk will give concrete examples of the ways Xen can add value to your platforms, not only by providing an excellent general purpose virtualization solution, but also by providing simple, yet effective ways to partition the platform into different security domains.
This presentation will include a brief overview of the Xen on ARM architecture, covering the key design principles employed. The techniques pioneered during the ARM port that allowed the Xen community to remove many legacy components from the Xen code base, streamlining both the ARM and x86 implementations. The talk will conclude explaining how to port Xen to any new ARM boards with the least amount of effort.
Abstract LuaJIT: Lua is a scripting language commonly embedded by web front-ends. Enabling Lua JIT compilation can reduce CPU usage when handling huge amounts of network traffic. This year Linaro (and others) started to work on porting LuaJIT to AArch64. Though the work is not finished we have made good progress. This presentation will briefly introduce LuaJIT, discuss the technical challenges of porting
to AArch64, and address the progress of the porting effort and the next steps.

LAS16-200: SCMI - System Management and Control InterfaceLinaro
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.

Embedded Recipes 2018 - swupdate: update your embedded device - Charles-Anto...Anne Nicolas
Nowadays a lot of embedded system are connected to Internet. And every years, more devices are available in the market but without maintenance. Due to this situation, a lot of security issues raised which could compromised the lifetime of the product and the privacy of their users. To fix these bugs, these security issues or to add new features, updating remotely these systems on regular basis is very important. We have to think about update process for each new product, to be easy, reliable, efficient and not too costly for the required bandwidth or hardware performances.
Several update designs are available to fit your requirements. Due to these constraints, you have to make choice and find the right balance.
Hopefully one free software allows us to perform this task in a easy and flexible way: swupdate. This solution is very well integrated with U-boot, buildroot and Yocto. You can describe exactly how the update should be done.
This talk is to explain the main designs to update an embedded system with pro and cons of all of them and then explain how to implement them with swupdate for your embedded system.

Introduction to Android ROM cooking, part of my AnDevCon workshop (AnDevCon S...Ron Munitz
Part of my half day tutorial on AnDevcon, November 2013, Burlingame, CA.
In this tutorial, you will have a hands-on journey of customizing and building Android for any X86-based device. We will first introduce the concepts of Android ROM cooking for any device and architecture. You will learn what Android is made of, and will build a minimal Android configuration that will run on a Virtual Machine, using the AOSP project. We will then survey the build systems of Android-X86 and 01.org's Android-IA projects, and find our ways through customizing those projects for arbitrary needs.
You will step out of the classroom with the ability to follow the exact steps made in the tutorial to jump-start building your own Android system for any Virtual Machine - and with the tools and knowledge to build it for any X86 hardware!
Note: The tutorial is extremely hands on. Although it is not a strict requirement, it is strongly recommended to come prepared with a setup of Linux or OS X with the source code for an Android platform from either source.developer.andorid.com {http://source.developer.andorid.com/}, android-x86.org {http://www.android-x86.org/} or 01.org {https://01.org/}.

>>WATCH THE WEBINAR HERE: https://codefresh.io/docker-based-pipelines-with-codefresh/
Most people think that Docker adoption means deploying Docker images. In this webinar, we will see the alternative way of adopting Docker in a Continuous Integration Pipeline, by packaging all build tools inside Docker containers. This makes it very easy to use different tool versions on the same build and puts an end to version conflicts in build machines. We will use Codefresh as a CI/CD solution as it fully supports pipelines where each build step is running on its own container image.

The current Hadoop ecosystem is challenged and slowed by fragmented and duplicated efforts.
An industry standard is required that translates to immediate benefits that will increase stability, capabilities and compatibility among Hadoop distributions. Its also important to include an open data management core with emphasis on making it enterprise focused.
The ODPi is a shared industry effort focused on build such standards and also promoting and advancing the state of Big Data technologies. Linaro is actively involved in this effort and also to make sure ODPi is ARM compatible.
This talk will go over some of specifications defined, Linaro's contributions, Roadmap and a quick demo

In GNOME, accessibility is a core value that touches all aspects of the system. [1]
From the infrastructure, to the graphical toolkit, to the applications, to the assistive technologies, accessibility has been a central consideration from the very early days.
On April 2011 GNOME 3.0 was released, and although GNOME and the accessibility made a huge effort, the accessibility support was not ideal. But not are bad news. Finally the accessibility technologies are starting to be used from the two main free desktops. AT-SPI is starting to be used on KDE distros, and Orca is starting to be functional with Qt apps. Since GNOME 3.0 a big effort was done in order to improve the situation. At the moment of this proposal writing an ATK/AT-SPI2 hackfest is being organized, in order to fix the issues from the framework itself.
The purpose of this presentation is explaining:
* Introduce accessibility on GNOME.
* Briefly explain the status towards GNOME 3.4
* Summarize the output of the ATK/AT-SPI2 hackfest
* Compare GNOME 3.0 vs GNOME 3.4
* KDE status and cooperation
* Future

Deep Learning Neural Network Acceleration at the Edge - Andrea GalloLinaro
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 qaLinaro
“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.”

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 Linaro
"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.

"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._

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

BKK16-310 March 9, 2016
Linaro Connect BKK16
2. Outline
● HiKey in AOSP intro
● Issues with AOSP & how HiKey addresses them
● How Linaro’s previous efforts helped us along here
● Unique requirements for AOSP devboards
● Lessons learned
● Accomplishments & future plans
● Questions!
4. HiKey + AOSP!
All well documented on the AOSP website:
https://source.android.com/source/initializing.html
$ repo init -u https://android.googlesource.com/platform/manifest
$ repo sync -j24
Grab & extract vendor binaries from here:
https://developers.google.com/android/nexus/drivers#hikey
$ source build/envsetup.sh
$ lunch hikey-userdebug
$ make -j24 droidcore
5. Past Issues with AOSP
● AOSP as Nexus only development
project
● Slow uptake of LTS kernels
● Devboards lacking integration seen
on form-factor devices
6. HiKey in AOSP
● Addresses a number of complaints we and
others have had with AOSP
● Provides a reference devboard in AOSP!
● Unlike nexus devices, HiKey will move
forward to newer kernel versions
● Takes Linaro’s previous efforts generating
Android builds w/ the latest kernels and
userspace but does it inside of AOSP
● Provides good testbed for validation
7. Device Released Kernel Kernel release date
Nexus 5 October 31, 2013 3.4 May 20th, 2012
Nexus 5X /
Nexus 6P
October 22, 2015 3.10 June 30, 2013
Slow uptake of LTS kernels
8. Vendors base their BSP trees
on whatever the latest AOSP
common kernel
Google generates AOSP
common trees based upon
what kernel versions their
partner vendors require
Circular blame
9. Put this to the test with HiKey
● When HiKey AOSP effort started, HiKey official kernel
was 3.18, which was the latest AOSP common git
branch
● Pushed to migrate to 4.1
● AOSP released experimental android-4.1 branch.
● Linaro helped push a number of fixes in for it and
reorganized the tree
● AOSP released an official android-4.1 branch!
10. Forward porting AOSP common.git
● Linaro has taken the effort for a number of years to
forward port the AOSP common.git tree to the latest
mainline release
● Provided members with a “preview” of what the AOSP
tree would possibly look like, allowing for early Android
development against newer kernels
● Provided practical experience with the AOSP common.
git tree
● Helped the Android upstreaming effort
11. Also put us a step ahead
● Allowed us to see where upstream changes collided.
● We had to resolve a number build fixes and issues with
the forward ported tree.
● So when AOSP common.git experimental trees
appeared, we had a number of fixes ready and waiting
to go.
● So when the experimental/android-4.1 branch
appeared, Amit Pundir was ready
12. Keeping it going for 4.4 and beyond
● After kernel v4.4 was released, Amit Pundir had a
forward ported tree ready.
● Sent it to Google developers, so it might be a helpful
reference when they do their experimental/android-4.4
release
● Google developers decided to just take Amit’s tree,
rather than do their own forward port!
18. Less obvious needed items
● Configfs gadget support
● “adb reboot bootloader”
● pstore
● easy firmware flashing
● handling different sized mmc & userdata
partitions
19. “reboot reason” functionality
● Communicates to bootloader to enter fastboot or
recovery mode on next boot
● Working with community to get a solution that works for
a number of different systems
○ Works with upstream nexus7 kernel and HiKey
○ Integrating w/ patches from Rockchip devs
○ Working to get it all upstream
20. pstore via DTS
● Allows for console and dmesg data to be preserved
after a crash
● With upstream code, pstore functionality is enabled with
custom platform driver
● Couple of attempts by folks to push patches to do this
via dts entries
● Nudged developer at Google to resubmit, hopefully can
get it queued soon
21. Other bootloader enhancements
● HiKey uses UEFI, which normally uses fat
boot partition
○ Preference is the standard AOSP boot image format
● Extending the UEFI and recovery loader
fastboot protocol support
● Supporting proper getvars for partition
resizing
22. Pain points and lessons learned
● For devboards, it’s really useful to have
USB host and gadget support working at
the same time.
● Being able to update the entire bootloader
via fastboot would be useful
● Devboard testing limitations vs form-factor
expectations (ie: hotplug testing!)
23. Since last connect....
● Forward ported HiKey patches from 3.18 -> 4.1
● Migrated from Lollipop to Marshmallow and master
● Collaborated w/ Google to release and fixup
experimental/android-4.1 tree
● Reorganized experimental/android-4.1 tree, which was
basis for android-4.1
● Added features expected on android devices (reboot
reason, pstore, improved fastboot) to HiKey
● Upgraded to mali r6p0
● Chased lots of bugs
● Provided reference forward ported 4.4 tree, which became
experimental/andorid-4.4 & provided fixes and cleanups, to
help create android-4.4
24. ● Migrate AOSP HiKey builds to android-4.4
● Move to Vendor/ODM partitions
● Continue pushing HiKey and AOSP common patches
upstream
● Continue rolling HiKey AOSP builds along to the next
LTS release (4.8-4.10)
● Power management & EAS test bed
Future plans
25. Linaro cross team effort!
● HiSilicon LT
● Build and Baselines
● 96boards
● Member Services
● LMG Kernel
● QA Services
