dmesg

I tried KMS for the first time on a Radeon HD4350 today. UMS works fine, and
Xorg doesn't complain anything about my screen's edid.

Everything works fine in KMS mode, I get full 1600x900 framebuffer, fast VT
switching etc.

KMS however fills my dmesg with EDID and composite sync errors:

"composite sync not supported"

 Review: https://bugs.freedesktop.org/review?bug=27708&attachment=41653

add edid strict option

The drm EDID checker is pretty strict about what EDIDs it will accept.  Try
this patch and add drm.edid_strict=0 to your kernel command line.

It stops spamming with drm.edid_strict=0 (2.6.37+this patch)

I also see this with Radeon HD 4350, kernel 2.6.36, driver 6.13.2 (and also
99), KMS. Monitor is a HP ZR24w, using DVI.

Jan 12 21:00:40 coolbox kernel: [drm:radeon_dvi_detect] *ERROR* DVI-I-1: probed
a monitor but no|invalid EDID

Is it any chance to add edid_strict parameter into kernel? 2.6.38rc2 still have
no it.

It hasn't been accepted into the kernel yet as the patch needs either better
bounds checking (to make sure we don't read past the end of the edid if the
size or number of extensions are wrong) or we need to set the taint flag.

I have similar problem on my Ubuntu box, with slightly different.
The mother board is an ECS A740GM-M v7.0, which uses AMD-740 chipset,
integrated ATI Radeon 2100. The chip supports multi-head, both VGA and DVI,
however, the manufacture installs VGA connector only, no DVI connector
installed. 
The Radeon driver, unfortunately claim has detected a connection onto DVI-0,
but with invalid EDID. But actually the board has no DVI connector at all! 
I'm not so sure whom we should to blame, the manufacture or the driver? The
driver scans the connectors that the video chip supports, how happens it claim
finding a connection on DVI-0? It is that because of the manufacture doesn't
pull the un-installed DVI port properly then causes floating signal be
recognized by the driver as a connection? 
Whatever the case, the problem is severer. Every 10 seconds, those invalid EDID
complain and RAW dump into syslog, causes over 100M/day increased in related
log files. Also, the system has been greatly degraded in performance. I also
have seen a complain saying when an attempt of workaround tried to removing X
system and leave the Linux box in text mode, and which causes all those error
message been pop up into console, makes the system unmanageable.
I will suggest to increase severity to this bug, since it causes the system
almost useless. 
The patch to loose EDID checksum will not be proper to my case. I would like
suggest to another approaching that set a static flag in the driver and report
the EDID checksum error only once, or repeatedly only when a run-time EDID
error report flag has been set. Those repeated EDID error only useful for a
on-site debugger and is really annoying to ordinary end user.

This is a different issue.  Please open a new bug for this and attach your xorg
log, dmesg output, and a copy of your vbios and we can add a quirk to fix the
connector tables.

To get a copy of your vbios(as root):
(use lspci to get the bus id)
cd /sys/bus/pci/devices/<pci bus id>
echo 1 > rom
cat rom > /tmp/vbios.rom
echo 0 > rom

And a copy of the pci device/subsystem ids for your card (lspci -vnn).

OK. I will open a new bug against this issue.
It will take a little while for me to reproduce it, since I have temporary fix
into my private kernel/module compiled. I need to reboot into the untouched
Ubuntu release to reproduce the problem.
Thanks.
