Well, as I understand it, maybe calling it a hw solution vs sw solution is a bit of a misnomer.. as they both require some hw and some sw to make it work. So maybe the AMD solution is the *more* hw solution.
At any rate, the patchset that Jerome is working on is intended to provide what would be needed for both AMD and NV.
Hmm, I was a bit uncertain about that do thanks for your insights.
BTW, did you ever receive my pm?
