GCN 1.1 On AMDGPU DRM Driver To Now Default To PowerPlay

Maybe this change has to do with the fact that Powerplay code miraculously solved the notorious DPM bug that some of us R9 390 users had the past 2.5 years. https://bugs.freedesktop.org/show_bug.cgi?id=91880

Still some ATi AGP regression on some ppc32 Macs: https://www.youtube.com/watch?v=uYx9X92iQHM

I think bugs.freedesktop.org is the place to report such issues.

That being said, I noticed that there was some problems between AGP driver and libata PATA for my Powerbook G4 Titanium. Switching to IDE driver or disabling AGP solved stability problems.

I wouldn't be surprised. I was plagued by that particular bug ever since I completely stopped using Windows a little over 2 years ago. I constantly had to force clocks up to keep the card stable. The moment that I enabled the amdgpu.dpm=1 kernel option, this bug practically went away with my MSI R9 390. For me, this was huge and eliminated years of headache.
