Thanks for looping me in here Rob, I hadn't been aware of this series.
Naresh, I'd appreciate it if you could CC me on any subsequent iterations; as linked above I've made some sporadic attempts at getting support for this functionality merged, and am certainly interested in any other efforts on that front.
A question for Mark though -- in one of my earliest stabs at this I floated the idea of using reg-userspace-consumer for it, but was told in no uncertain terms that that driver was for testing only and should under no circumstances ever be instantiated in a production system. Has the thinking on its usage changed in the last year or so such that this approach was deemed okay?
Thanks, Zev
