The plan is to solicit ideas for our 2010 contract work projects.

Each year, CELF spends money on contract work to improve Linux for use in embedded systems. Some of the projects we have sponsored in the past include Linux-tiny, DirectFB enhancements, smem, and Squashfs mainlining. Usually, our process involves querying forum members about their desires and building a project list from that. This year, we are opening up the process and asking for your ideas and proposals as well. maybe i missed it, but there doesnt seem to be too much emphasis on working with the respective projects and getting merged. that seems like one of the most important aspects of doing any enhancement work as anything not merged means it'll quickly be left behind and largely go to waste. -mike -- To unsubscribe from this list: send the line unsubscribe linux-embedded in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I agree. Many of our contracts have a financial incentive built in to get mainlined. Some of our projects' sole objective is to mainline already existing stuff (like Linux-tiny and SquashFS). If anyone has a feature that already exists, but that they think should be merged with the relevant upstream project, that's a good candidate for a proposal. One obvious project, which I'm waiting to see if someone else submits, is to pay someone to mainline some of the outstanding Android patches into the Linux kernel. -- Tim = Tim Bird Architecture Group Chair, CE Linux Forum Senior Staff Engineer, Sony Corporation of America = -- To unsubscribe from this list: send the line unsubscribe linux-embedded in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
