Description Bruno 2010-02-11 12:10:27 UTC
Nouveau does not seem to fetch EDID from my monitor (Iiyama E431S, 1280x1024) connected via VGA to MSI K7N420 Pro, using the onboard nforce graphics.

(see bug #25619 for full lspci)

kernel version used: 2.6.33-rc7 from Linus at commit e28cab42f384745c8a947a9ccd51e4aae52f5d51 with nouveau/for-airlied branch at commit 13876c6e5fec94e9ea51b73ac025583dd7655345 + commit d5f669822059651c4db1be94cbab605e1ba5a389 from nouveau/master.

Under /sys/class/drm/card0-VGA-1/ "edid" is empty and "modes" lists only a few modes: 1024x768 800x600 800x600 848x480 640x480

Is there anything additional I could provide to help getting the EDID reading working?

It would be interesting if you grabbed some logs having loaded nouveau with the "reg_debug=0x70" module parameter.

Here it is, though some parts seem to be missing because of kernel buffer overflow with syslog getting no opportunity to capture it all (even though it's already pretty large, shift 18)
Comment 3 Francisco Jerez 2010-02-13 09:44:28 UTC
It seems nv1a has the DDC lines somewhere else. Is "nv" able to fetch an EDID? Probably not but it's worth a try. If it doesn't then an mmiotrace from the blob would be useful (see [1] and the docs in the kernel tree).

nvidiafb seems unable to read EDID, none of the 3 i2c channels it registers return an EDID.

Xorg with nv driver 2.1.6 isn't able to get an EDID either.

Will now have look at the blob to get the mmio trace (with 2.6.30.4 kernel).

MMIO trace, captured with not so recent 2.6.30.4 kernel and 96.43.14 blob can be found at below URL (attachments being limited to 1MB):
  http://homepage.internet.lu/BrunoP/nvidia.tbz2

The kernel log shows first loading blob 96.43.11, then later on 96.43.14. This is due to Xorg that got updated recently and older userspace blob complaining about dependencies, so I had to update the blob as well.

The Xorg server crashes shortly after loading but has already read EDID by that time so I guess no need to care about that :)

Yes there is a difference, it now says that my VGA monitor is connected via DVI (no such connector!) and does not list card-VGA-* anymore under /sys/class/dri/.

I would say the visible part is more bad than good... If you need more info, please ask.

An i/o trace of your BIOS posting the card might be useful, to do it you would have to download [1], compile it and run (as root and in text mode, i.e. neither X nor fb drivers running):
# ./vbtracetool -p -l 2>nv1a_post.log

What am I missing, it just returns the following on me, running it as root:

./vbtracetool -p -l
mmap /dev/zero: Operation not permitted
Failed to initialise LRMI (Linux Real-Mode Interface).

This was caused by /dev being mounted noexec

Note, the posting done by VBTraceTool is not perfect, display show just kind of garbage (mostly black but a few fancy colored character placeholders)

Comment 17 Ilia Mirkin 2013-08-18 18:09:40 UTC
It appears that this bug report has laid dormant for quite a while. Sorry we haven't gotten to it. Since we fix bugs all the time, chances are pretty good that your issue has been fixed with the latest software. Please give it a shot. (Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git versions.) If upgrading to the latest isn't an option for you, your distro's bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs that haven't seen updates since 2011. If the original issue remains, please make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/ for what we need to see, and re-open this one.

Thanks,

The Nouveau Team

Thanks for re-testing and sorry the issue is still there =/

One thing that does appear to be missing from this bug report is your vbios (/sys/kernel/debug/dri/0/vbios.rom).
