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).
This is a discussion on various methods put forward to reduce the size of Linux kernel and user space binaries to make them suitable for small IoT applications, ranging from low hanging fruits to more daring approaches. Results from on-going work will also be presented.
This presentation will give an overview of the suite of reference security solutions developed by LHG. The solutions all have OPTEE as the secure OS running on ARM TrustZone integrated with DRMs such as Microsoft PlayReady and Google Widevine on both Linux and Android platforms. The secure video path implementation strives to use common elements across Linux and Android based solutions.
The Energy Aware Scheduler relies on a power model, rather than on heuristics, to make decisions and reduce power usage. As a result of this fact-based decision making EAS presents very few tunables and thus requires a significantly different approach to tuning and optimization when compared to the traditional tune/benchmark/repeat cycle. Tuning EAS has perhaps more similar to debugging: using trace tools such as ftrace, kernelshark and LISA, we can examine its decision making and look for ways to improve this decision making. This talk will offer a practical introduction to using these trace tools.
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.
Time Sensitive Networking (TSN) is a set of protocols and extensions that allow precise control of traffic latencies over standard Ethernet and is of growing importance in Automotive, Industrial, and Professional Audio/Video domains. This talk provides an overview of the topic and will include a dialog to help set priorities and next steps for work in this area with other interested groups.
