The series is mostly done, but it needs a few last tweaks to make it acceptable for merge. Chris noticed that the series doesn't properly work with the new VCS2 code that Daniel merged a couple of weeks ago. I too noticed this, but was remaining silent in the hopes that we could actually try to make progress. I raised concerns about this during the VCS2 merge on IRC. I only took a quick look, and it seems it's not too bad to implement, but it requires a bit of brain power to make sure it's correct. The series is broken in another way because the new semaphore decoding which Daniel added. Ville posted a fix that looked sane to me, but I haven't a machine to test with. I'd recommend someone try to beat that into shape and test it. The series should be /okay/ without that though. So here are the latest patches that I have. I just don't have enough time before my vacation to get these things done. They've gone through 5 rounds of rebase since the first series was posted on 12/13/13. They get the first thumbs up from Ville on Mar 5 (a couple of minor tweaks were required and could have been easily done by the maintainer). I've fixed everything I am aware. If someone could take over the patches, and get them merged, I think it'd really help in getting this useful feature added to our driver for gen8. * The last two patches aren't needed, but are here for posterity. If nobody has taken this over when I return I will see if I can complete it.
