[Intel-gfx] Support for HDMI on ASUS P5E-VM HDMI (G35 chipset)

[Mike Wright]

Hi Chad and Hong,

I'm not actually trying to run an interlaced mode :-)  It is not in my
Xorg.conf anywhere.

I'd lke to run 1280x720p @ 50Hz.  I can't get that to work though.  In
fact, it doesn't seem to matter what mode I tell the driver to use, I
always get a blank screen.  For some reason X (possibly not the Intel
part of the stack though) thinks that my TV only does 1920x540p(i?)
But I listed the modes from the TV's manual and it support many modes
over HDMI.

As I said I'd like to get 1280x720p at 50Hz working.  That would be the
best compromise on the TV's physical 1024x768 resolution.

So guess there might be two bugs here:
1)  X is not decoding the Pioneer EDID correctly or Pioneer is sending
the wrong info.
2)  If I ignore EDID (via NoDCC=true), the Intel driver doesn't seem
to be able to use built-in (well known???) modes like 720x576.

I know others are having a lot of trouble using HDMI on this board.
Gordon from Intel has noticed that others are having problems and
said:
"The main issue is that P5E-VM is using SDVO HDMI not native HDMI,
while the SDVO HDMI is not Intel product and we don't have enough
documentation on this.  Hong is working on this and will get this list
informed once he get the info."

So Hong, I'll wait and see how you go with this board.  If you need
any more info from me I can help out.  Also I'm happy to look at code
and debug etc, but I'll need the Silicon Image specification for the
HDMI part of the pipeline.  I might be able to get more done from my
end especially since there could be an issue with my Pioneer (though I
doubt it becuase people have it working fine with NVidia boards)

Mike.
