I didn't see how you confirmed that it was good data rather than just conservative, power hungry values ;-) Nevertheless, getting eDP to light up is a massive step forward on those machines. Applied (after smoke testing on my non-eDP machines) to -next with some minor amendments (style and compiler warnings). Thanks Jesse, and to everyone who tested the various hacks, maybe there is some light at the end of the eDP tunnel! -Chris -- Chris Wilson, Intel Open Source Technology Centre
