Interlace modes with r600 KMS

[Marius Gröger]

Hi All,

I'm not able to use interlace modes (r600 KMS from d-r-t, HDMI output, 
Xorg stack on xorg-edgers, Ubuntu lucid). All interlace modes which are 
defined in EDID seem to be pruned and don't appear in xrandr. Manually 
adding a mode using xrandr does work, and the TV set detects the mode, 
but the image shows horizontal lines. No crash though.

Interlace modes did use to work fine in the past, but I don't know when 
they ceased to function.

What is the status of interlace modes on this kind of setup? What more 
tests or logs would be helpful to analyze the problem? What are other 
people's experiences with this?

Thanks
Marius
