No one that I know of is actively working on this but maybe someone has got it working and would like to share?
In terms of development, the SE mode code is there and the FS mode code that is hardcoded to single threaded instances needs to be expanded for multiple threads (e.g. change pendingInterrupt[0] to pendingInterrupt[tid]). Of course, there are probably a couple startup issues (e.g. configure one CPU to maintain multiple CPUs so to the OS can logically treat a SMT thread as another CPU). And there will more than likely be a couple of corner cases before one could claim absolute functionality. The good thing is that since single-threaded O3 FS working, there's a good amount of the code base there for reference once someone decides to take up the task.
