Hi,

I'm trying to play with some different AVI InfoFrame settings for the =

HDMI output on my DG45FC (G45 Intel graphics hardware, HDMI connector on =

the motherboard) but I can't seem to find any references to it in the =

i915 driver or in the programming specs.

drivers/gpu/drm/i915/intel_sdvo.c has code for setting an avi infoframe =

for hdmi outputs, but it doesn't seem to be used on my board (I tried =

sprinkling some printk's in there). I guess it's only for ADD2 type =

addon boards?

So far I'm guessing that drivers/gpu/drm/i915/intel_hdmi.c is =

responsible but there is no code in there that deals with the avi =

infoframe and I haven't been able to find anything in the programming =

manuals from the intel linux graphics website.

Could anyone point me in the right direction?

And on a related note, does anyone know if the hardware supports HDMI =

CEC and where I might find the relevant hardware documentation?
