With DC support does this mean GCN 1.0 cards will be able to support Freesync?

This needs attention.

Dave was one of the guys who sided with ATI to counter the real open source driver written by SuSE for AMD (ATIs new owner which was working hard to try to get ATI under control and to clean up the big mess that was there) and Dave only started development close to 5 months after the development of the real driver had started, and 2 months after the real driver was made public. Dave did more to keep the fglrx ways going than he helped progress either technically or with respect to open source affinity.
Also, the original KMS infrastructure was laughable to any display driver developer worth their salts. The most amazing transgression is how we only got useful cursor support like 3 years ago, and cursors are trivial.

Except that it took years just to get modesetting up and then in the end you had to use AtomBIOS anyways.... Hindsight is 20/20 and now we know for sure what was right...
(full disclosure: i was always very much in favour of using atombios for ASICInit() as that beat the full int10 bringup by several orders of magnitude, and it would be easy for me or others to go and replace ASICInit with 400 or so lines of real code in the future, a future that ATI definitely did not want to see happen).

AMD doesn't have many resources to spend on this. And I'd rather see new GPUs supported well, rather than old ones.Originally posted by xiando View PostI have a Radeon 7850 (which I'm not using) from 2012 and that's GCN so it's been around for at least 6 years, perhaps 7 because I'm fairly sure there were some other GCN card(s) before it.Originally posted by schmidtbag View PostThe HD 7000 series was released in 2012. Not sure how that equates to 4 years.
Originally posted by MagicMyth View PostI think polarathene is referring to AMD continuing to release "new" cards based on GCN 1.0 for several years.
