Subject: radeonfb monid i2c bus
Date: Fri, 6 Jun 2008 12:01:51 +0200	[thread overview]
Message-ID: <20080606120151.7976df45@hyperion.delvare> (raw)

Hi Ben,

Can you explain what is the "monid" i2c bus on Radeon adapters? I have
two Radeon chips here, an M6 in my old laptop and a 9200 in my desktop
system. On the M6 there is nothing on the monid bus. On the 9200, the
monid bus doesn't even work, every access results in timeout. The
radeonfb driver doesn't even look for EDID EEPROMs on that bus (except
in debug code.)

So I'm curious why you create this i2c bus if you don't need it.
Have you ever seen a Radeon adapter where there is something on that
bus?

Thanks,
