Supposedly Alex applied it to his drm fixes tree, but I don't see that he's pushed anything into his drm-fixes-3.13 tree yet. Guess I'll have to wait an extra RC or build the kernel myself.

How does the performance compare to the proprietary driver? To equal priced nvidia using proprietary?

Radeon HD 7970 GHz Edition
This list includes any cards identified by wikipedia as having a variant of any of the above chips (the pro/xt/etc variants). Given that I haven't looked at the kernel sources and register specs, I can't say for sure if all of the above cards are affected, just that they are descended from Bonaire, Hawaii, Tahiti, and Pitcairn. At the high end it looks like there's also a "Malta" chip which isn't included in the above list, but it's possible that maybe those might be affected as well. The Malta looks on paper like it's a dual Tahiti XT2 solution, but I haven't spent the time to research it.
Note: I don't work for AMD, and most of the above is either sourced from Wikipedia or guesswork based on my experience.

Can we say:
Oooops
I'm actually glad this was a simple issue. Makes you wonder how many other performance regressions are out there as something gets looked over or bypassed.
Anybody have nay idea of when Southern Islands enabled APU's will ship?

What was the rest of the specs on the box you tested this on? Just wondering - we might be able to find something similar in the open benchmarking site to compare the Catalyst results to.
