Android runtime (ART) has evolved from an AOT compiler (in Android L & M) to a hybrid mode runtime (in Android N) which combines fast interpreter, JIT compiler and profile guided AOT compiler. In this talk, we'll take a look at all these important changes in Android N. For example, the design and implementation of JIT, hybrid mode, tooling support, etc. This talk is meant to help Linaro members and developers to have a deeper understanding of ART in Android N, and to help them face the challenges of the new behaviors of Android runtime.

The Linaro Enterprise Group has been driving the work to implement, upstream and maintain UEFI and ACPI support on ARM platforms since its creation in 2012. Over the years, the team has initiated new activities, namely the OpenPlatformPkg proposal to support multiple SoCs and multiple platforms in EDK2, as well as supporting more and more features on ACPI, e.g. recently, Console Selection, APEI, PCIe, NUMA and new GIC implementations. In order to successfully deploy ARM servers in production, it is required that firmware (BIOS) engineers and kernel engineers work in close collaboration and drive the addition of new platforms, improved SoC support, etc. Recently Linaro founded devicetree.org to support making device tree a properly managed and supported standard. This includes reducing fragmentation, improving maintainability and increasing multiplatform support in hardware description thanks to an open process that encourages wide community participation and the current best practices and technology. The purpose of this conference is to bring the key developers and maintainers from all camps in the same place, review the status and plan the next steps. Title:ARM64 ASWG and Linux ACPI update Abstract: As presented at previous connects an update on the current support for ARM64 at ASWG level and the hot topics. Also an update on the support that is mainline in the Linux kernel for ARM64 ACPI support. Also covering the next steps for both ASWG and Linux support. Followed by a discussion period. Speaker: Al Stone, Hanjun Guo Notetaker: Graeme Gregory 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. Speaker(s):Charles Garcia-Tobin Notetaker: Title: Tianocore Progress and Status A brief update on the progress of ARM64 support in EDK2 and OpenPlatformPkg. Also covering the next steps. Followed by a discussion period. Speaker: Leif Lindholm Notetaker: Graeme Gregory Title: Secure Boot A 101 style introduction to what Secure Boot is as Secure means different things to different people. Covering the current status, what features are implemented currently on ARM64 and what features should be implemented in the future. Followed by a discussion period. Speaker: Ard Biesheuvel Notetaker: Graeme Gregory Title: RAS What is it? Why do we need it? A 101 style introduction to RAS, its purpose and how we use it on ARM64. Covering current status of implementation in ASWG specs and Linux kernel. Plans for future features that are essential for ARM64. Followed by a discussion period. Speaker: Yazen Ghannam, Fu Wei Notetaker: Graeme Gregory

**Title: Corporate Open Source Fail** What makes companies with good intentions fail so miserably at open source? How can we (as engineers and managers) influence our bosses to “do the right thing”? “We’ll just make a new open source community.” “You can fix up that code later.” “It’s taking too long to get this upstream.” Many companies have good intentions of being productive open source citizens. However, those good intentions often get thrown under the bus when product deadlines or legal issues loom. This talk will walk through a series of common corporate open source pitfalls and the executive and manager thinking behind those decisions. We’ll discuss ways engineers and managers can develop empathy for their corporate overlord’s needs, in order to influence their strategies around open source. **Bio** Sarah is the founder of Otter Tech, a consulting company offering open source training, software development, and diversity consulting. http://otter.technology Sarah Sharp is a Linux and open source developer, and has been running Debian-based Linux systems since 2003.

ARM mbed OS is an open source embedded operating system designed specifically for the “things” in the Internet of Things. It includes all the features you need to develop a connected product based on very small memory footprint ARM Cortex-M microcontrollers, including security,connectivity, an RTOS, and drivers for sensors and I/O devices. You can start developing with mbed OS 5.1.0 today using a choice of 40 different development boards from 11 different providers and a wide choice of toolchains including a complete command line build management and configuration tool mbed CLI, industry standard desktop IDEs or ARM’s free online IDE.

ARM TrustZone is a critical technology for securing IoT devices and systems. But awareness of TrustZone and its benefits lags within the maker community as well as among enterprises. The first step to solving this problem is lowering the cost of access. Sequitur Labs and Linaro have joined forces to address this problem by making a port of OP-TEE available on the Raspberry Pi 3. The presentation covers the value of TrustZone for securing IoT and how customers can learn more through this joint effort. Embedded systems security remains a challenge for many developers. Awareness of mature, proven technologies such as ARM TrustZone is very low among the Maker community as well as among enterprises. As a result this foundational technology is largely being ignored as a security solution. Sequitur Labs and Linaro have taken an innovative approach combining an Open Source solution – OP-TEE with Raspberry Pi 3. The Raspberry Pi 3 is one of the world’s most popular platforms among device makers. Its value as an educational tool for learning about embedded systems development is proven. Sequitur Labs have also enabled bare metal debugging via JTag on the Pi 3 enhancing the value of the Pi 3 as an educational tool for embedded systems development. The presentation will focus on * ARM v8a architecture and instruction set * ARM Trusted Firmware * TrustZone and OP-TEE basics * JTAG and bare metal debugging the Raspberry Pi 3
