Martin's soon back from vacation.

I don't see Jani on the CC, but if this needs new API from kernel, bug about that should be linked here. Is there one?

You didn't mention in which use-case, on which distro and with which exact HW you've compared modesetting and Intel DDX performance, but in our tests Intel DDX has been somewhat faster on average. As to reliability, there have been issues with DRI3, but those have been fixed in X libraries, Mesa, Intel DDX etc. Mainly you need to use new enough (full) stack.
