This session will cover the state of android-4.4: total patch count or lines of code sitting out of mainline, their upstream status, new patches added (e.g sdcardfs, dm-verity etc), patches dropped from android-4.4 either in favor of upstream patches (e.g. siockilladdr, switch class etc) or they are obsolete and no longer used in AOSP (e.g. uid, n/w activity stat etc).
System has a lot of interconnect bus that have to be set to provide throughputs to devices of the system. We are working on adding missing pieces to let device set the performance requirements to the performance provider that are interconnect bus.
This survey of topics covers the engineering output of recent Android related projects in LMG and some future plans. This includes Memory Allocators, Filesystems, LCR news, Work on both gcc and clang based toolchains, Increased participation in upstream development as well as a quick overview of some upcoming topics. Kernel possible topics: Generic Build: where we are at
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.
The new LAVA dispatcher allows explicit control of starting/controlling guest. Walk through how to use V2 dispatcher for KVM and other VM testing and explore usage of libvirt etc. Share experiences in using V2 dispatcher in general. Plan support for migration and other advanced multinode tests.
SoC Vendors, board vendors, software middle layers, scripting languages, etc all need to have access to system configuration information (pin muxes, what sensors are on a system, what amount of memory, flash, etc, etc). We need a means to convey this in a vendor neutral mechanism but also one that is friendly for Cortex-M/constrained footprint devices. This session will be to discuss the topic, how its done today, what kinda tooling might exist from different vendors, what we could utilize (device tree) and what issues that creates.
**Title: IoT Zephyr**
Overview of IoT Zephyr
Geoff Thorpe heads up security within the Microcontroller group of NXP, where the intersection of device security and network security gives him a headache commonly known as “IoT”. His early experience with security topics was very software-centric, as a long-standing member of the OpenSSL team and a contributor to related open source projects. After many years veering off into semiconductors and hardware architecture, his software-bias has been domesticated to some extent but not eradicated.
OpenStack is powering the next generation of the opensource cloud on a global scale. During this presentation, we will touch on three themes, running an OpenStack based cloud in production by Gema Gomez and Andy Doan, followed by Marcin talking about the packaging and bug fixing on archives required to make that happen on AArch64. Jack He and Yibo Cai, will explain what it is like working with the the upstream project, the development environment, the current patches and what needs to be done next. Then Gema Gomez will Introduce the OpenStack Interop Working Group. Why is interoperability important for OpenStack? And What is Linaro doing to improve the interoperability of OpenStack?
