Work sessions are for Keystone contributors to discuss implementation details and making quick progress over specific issues, in a small work group environment.
This work session is to tackle some of the tasks related to the stable KSDI (Keystone Driver Interface) specification. This will include determining the order of driver interfaces to be moved to the "Stable" model, enforcement of the stable interfaces, and any design work related to the new interfaces.
