<p>Added body to Mainline Android kernel functionality page</p> <p><b>New page</b></p><div>; Summary: Mainline Android kernel functionality<br /> <br /> ; Proposer: Tim Bird<br /> <br /> == Description ==<br /> Android has some unique functionality that is not currently mainlined,<br /> e.g. ashmem, logger, binder and so forth.<br /> <br /> Mainlining these aspects of Android would reduce the overall<br /> maintenance and integration cost for working with Android.<br /> <br /> The problem of wakelocks (/suspend blockers, etc) have been<br /> discussed and debated extensively. Other specific features<br /> that Android adds to the kernel are less controversial, and should<br /> be added incrementally over time.<br /> <br /> A big issue is whether the Android user-space code would be modified<br /> to match the kernel code as modified to be suitable for mainlining.<br /> <br /> == Related work ==<br /> * [[Android Kernel Features]]<br /> * [https://blueprints.launchpad.net/linaro/+spec/tr-kernel-android-upstreaming Linaro kernel-android-upstreaming project]<br /> ** Linaro seems to have a project in-progress in this area, with some involvement by Paul McKenney<br /> * https://lkml.org/lkml/2010/11/6/154 - e-mail by Ted Ts'o about Android out-of-tree patches<br /> ** https://lkml.org/lkml/2010/11/6/177 - response by Greg KH<br /> ** https://lkml.org/lkml/2010/11/10/433 - note by Rafael Wysocki that wakeup sources may solve some problems<br /> * [https://github.com/gregkh/android-presentation/raw/master/android-kernel.pdf Presentation by Greg KH on Android patches]<br /> <br /> <br /> == Scope ==<br /> I would recommend starting with something simple (like logger or ashmem) and working from there.<br /> The amount of time to mainline stuff is notoriously difficult to estimate, but possibly<br /> 4 weeks per function, for simple things.<br /> <br /> == Contractor Candidates ==<br /> unknown<br /> <br /> == Comments ==<br /> <br /> [[Category:Project proposals 2011]]</div>
