I'm working on this, since when I plug in a 2nd screen in my own edp machine, the bios doesn't light up the internal panel and our code can't light it up, too. Unfortunately progress is slow, but you can try my current wip state at http://cgit.freedesktop.org/~danvet/drm/log/?h=for-pzanoni Please attach dmesg with drm.debug=0xe if you try this kernel. Backlight works now for me, but I still have issues with edp link training here. Cheers, Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch
