I've considered this again, and it should fit neatly into the existing framework. If we want to use the dither on the lvds port on those platforms, but keep dithering on the pipe for e.g. DP we could switch lvds_compute_config to not clamp the bpp and then just enable the port dithering if config.pipe_bpp != 18. There's some further patches which unify this a bit, I guess we can discuss this a bit more once I resend them. -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
