E-EDID support: read out extension blocks

[Christophe Oosterlynck]

Hi all,

to be HDMI compliant, extension blocks provided by E-EDID should be read
out. It seems that X doesn't do this.

I've been browsing through the code and found a commit [1] which introduced
the 'complete' parameter to xf86DoEEDID. This is being called with
complete=FALSE from xf86DoEDID_DDC2 [2]. I was wondering why and if there
is any other code path where this function is called with complete=TRUE? Or
doesn't X support reading out extensions blocks by default and can it only
be done by calling xf86DoEEDID myself?

Best regards,

Christophe
