Hello, I currently had codes, implemented as regular seL4, since camkes does not support some features (i.e. transferring capabilities or accessing address space outside the process), Everything is fine up to this point but now I want to create several drivers. And I found that the best and easiest way to do that is to use camkes. So is it possible to use existing regular codes in conjunction with camkes? Or would the best way be to implement drivers as regular seL4 codes? Thanks, Oak -- Norrathep (Oak) Rattanavipanon M.S. in Computer Science University of California - Irvine
