This session is an advanced course on Linux kernel upstreaming fundamentals. The course covers how the arm-soc kernel tree is maintained and why that is important to ARM Linux kernel developers. The focus of the course is the explanation of the detailed mechanics of creating and posting patch series to upstream mailing lists for several common cases. Annotated session content is made up of previously upstreamed ARM support captured from emails to the kernel mailing lists. The target audience is both software engineers and engineering managers preparing to upstream software into the kernel. The topic requires a solid background in software configuration management terminology and the git SCM tool as well as a good technical understanding of the Linux kernel itself.

This session is an introductory course on Linux kernel upstreaming fundamentals. The course covers the definition the Linux mainline kernel tree as well as the maintainer hierarchy and processes used to contribute software into the mainline kernel. Special focus is given to understanding what documentation will help understand the process and mechanics in more detail while breaking the workflow into the various steps of upstreaming software patches. The target audience is both software engineers and engineering managers preparing to upstream software into the kernel. The topic requires a solid background in software configuration management terminology and the git SCM tool as well as a good technical understanding of the Linux kernel itself.

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.

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).
