When you adopted commercial software for your development, its support model might be relatively simple. If you pay money, someone provides a support for you. However this model does not apply for opensource as it is not developed by a single entity. Linux development is shared effort contributed by a broad range of global developers, and it is delivered as the no-warranty basis. I wonder IVI developers who start using opensource, may have confusion about a support scheme. Linux kernel community does not care for each product development, and you cannot send your question to the community mailing list. Then, who can help you? Of course, Linux is already adopted in various mission critical scenes, and it implies there exist some supporting structure. In this session, I will introduce who are doing what for Linux and how you can find a solution for your embedded Linux system.
