As I understand it, the Yocto Project does not intend to continue support for any release within those time frames. This is where the end user and/or OSV will need to determine the support requirements and support policies outside of what Yocto provides. Yocto does not provide an "application framework" (this was a big selling point of Moblin/MeeGo). Yocto allows someone to generate their own Linux distribution for their own needs. What this means to someone like GENIVI is that they CAN create an application framework based on Yocto, but it would be work they would need to do (with us) likely in using a custom layer that specifies specific distribution settings, enhancements, etc. Yocto is a cross-compiled build environment. This is a departure to a lot of the Moblin/MeeGo work that has occurred in the past. The advantages are you can use any commodity PC to target any (supported) architecture. Disadvantages are that when you introduce new code, you need to ensure that it has a recipe (build instructions for bitbake) and can cross compile. If everyone has to do the same work over and over, this can be time consuming and counter productive. If people work together, the time and support burden are dramatically reduced. This can help negate issues people have had in the past with cross compiling. Note: Yocto -does- have a self hosted compile environment if it is needed, this is usually when cross compiling isn't easy to do for some reason. Yocto currently does not support a set of "blessed" binary packages. Our expectation is that the users of Yocto will create their own distributions, and then in turn provide binary packages to their own customers/users in whatever mechanism is appropriate. If the automotive folks want to start with binary packages and simply add their own stuff on top, someone will need to create the distribution (see above about settings and frameworks) and provide the "blessed" package feeds. Anyone have any other questions/comments let me know. I'm pretty familiar with automotive and GENIVI requirements as of a few years ago. I'm a bit out of date with the current work however. --Mark > /t > > */Tracey M.
