Afaict that quirk is for pnv only. > gma500 also seems to use DSPCLK_GATE_D to disable clock gating for > some DP stuff on CDV. Considering the lineage we need to find out > if that's something that affects VLV as well. I guess we could add it once we need it in a vlv clock gating functions. Generally we tend to only add clock gating defines when we need them, since there are soooooo many. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
