Thanks for your email!
"1. Did anyone at Intel get around to decoding that EDID block yet?"
I 'm focusing on EDID extension, in order to push CEA extension mode, recently I did a patch to handle detailed timing block including both EDID and CEA extension.
"2. Secondly, can the intel drivers program an arbitrary mode over
HDMI like NVIDIA can? If so then I could ignore this whole EDID thing
and just program the right mode."
Currently our driver don't support interlaced mode such as 1920x1080i, but do for others mode completely.
after pushing CEA extension into Xorg, I 'm going to do the feature for interlaced mode.
