Hi, my tft is a little bit blu, so, changing CPR in omap3 I see I can fix the problem. I'll try to implement something like this http://en.wikipedia.org/wiki/Color_calibration#Display . But I don't find an interface for it neither in the more general FBdev. I could add an ioctl like OMAPFB_GET_COLOR_KEY, but arriving to drivers/video/omap2/dss/dispc.c dispc_mgr_set_cpr_coef fucntion. I have to build/buy a calibration software, but I think I can get really nice results. I'll obviously start with sysfs for debug, but I'd like some ideas to develop "the right thing".
