I was browsing through kernel code and found no support for mmaping of remote RapidIO device address ranges. Therefore some questions: 1. Is there any open-source implementation of this functionality? There are some vendor supplied close-source drivers which do this. 2. Are there any specific plans to implement it (agreed upon API, user space stuff, etc)? Thanks.
