A bit surprising since the only psr issue I was aware of was that we failed to entire psr (and that is likely a fumble in the tracking of cursor updates). Otoh PSR isn't enabled on baytrail because it's hang-happy there and the testcase we have for all the corner-cases in psr tracking turned out to be completely broken and no on fixed this yet. Anyway thanks for digging this up and pushing the revert yesterday - I was already in w/e mode ;-) Cheers, Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
