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.
