dmesg after rmmod nouveau

i'm trying to get kms working on my nv31m on gentoo using the x11 overlay, when
i do modprobe nouveau modeset=1 the screen still stays the same resolution
(80x25 chars) and the cursor freezes in place though i'm still able to type
stuff.
when i rmmod nouveau i get an oops (attached)
everything from the overlay is up to date.

i'm using nouveau-drm instead of x11-drm
i have FRAMEBUFFER_CONSOLE=y

You seem to be using old kernel with serious bugs, see
http://nouveau.freedesktop.org/wiki/UpstreamKernelIssues for more details. You
should try building the whole kernel from nouveau/linux-2.6 repository if
possible, otherwise upgrade to 2.6.31.

Also, a memory corruption bug was squashed recently in nouveau drm, can you
verify this issue still happens with current git?

dmesg on 2.6.31 after modprobe without modeset=1

Using 2.6.31 now, rebuilt everything from the x11 overlay, but when I do
modprobe nouveau modeset=1 the screen turns off and the system freezes (sysrq
doesn't work anymore), nothing in the log about that after reboot.

Attached the dmesg without modeset=1, but I guess it won't help much.

Nouveau-drm package from x11 overlay is still using master-compat, which is not
up-to-date, and does not contain the fix.

I updated the master-compat right now, it will propagate into the snapshot
nouveau-drm uses within six hours, IIRC. I do not intend to update
master-compat anymore.

I'm using nouveau/linux-2.6 now, the system freezes here too with the latest
commit (4e9caac6c3f7888848e1614bca0b4551fa196ce6), doing a bisect to find out
when the freeze was introduced but compiling a kernel takes about half an
eternity on this notebook. 756 revisions left to test after this (roughly 10
steps). Getting the old behaviour with 3f4f9a450f602251839f986f8785a78803c7d8da
from 2009-08-08.

66960bf357b134b46044f46f5e80ed4d8ed86220 is first bad commit
drm/nouveau: Import >=nv17 TV-out support.

With the commit before that (b07297c4d302c8b1bb476cf8f4b67171dd1b6d38) I get
the old behaviour.

Your bios tables seem a little bit misleading, does the attached patch change
anything? (please attach some logs if it works around the hard lockup).

dmesg with patch1

KMS seems to be working fine with patch1.
With patch2 I still get the freeze.

So your card probably needs something to be done differently for TV-out load
detection... An mmiotrace is likely to be very useful (see
http://nouveau.freedesktop.org/wiki/MmioTraceHowto).

Yeah, you'd better send it to mmio.dumps at gmail.com.

patch3.diff

The attached patch should do the trick, nv31 TV load detection seems to be more
like nv17 than other newer nv3x. I probably did some other untested assumptions
about nv31 TV-out, so it would be nice if you tried it (Note that you'll surely
need patch2 for it to work), but don't worry too much about it :-)

dmesg with KMS and a TV connected

KMS is working with patch2+3. Not sure how to enable TV out though. Running
xrandr just returns "Output TV-0 is not disconnected but has no modes", no
matter what I pass to xrandr. TV out is working fine if I set it up with the
blob and nvidia-settings.

Hm, that seems to be because of some recent DRM changes... the attached patch

Actually no need for that, just updated xrandr from 1.2.3 to latest git,
working fine now.

Weird, it really shouldn't have worked without it. Pekka has pushed the fixes
so I'm marking this as closed.

Thanks!
