Dmesg with call trace.

Mentioned on #radeon:

Hello, I have recently adopted a PowerMac G5 (machine7,3 circa 2003-04) with a
ATI Radeon x800 XT Mac edition (AGP chipset R420 JH). When attempting to use
the new KMS Radeon drivers (kernel v. 2.4.34) I get a seg. fault and kernel
Oops. I am using PPC gentoo linux with 64bit kernel and 32bit userland. I have
collected the call trace that is given after inserting the module with
modesetting enabled. Attached is my entire dmesg with the call trace at the
bottom. Inserting the module was done via SSH with no other fb or video drivers
enabled in the kernel.

Let me know if I can provide any additional information that would be useful
and I am happy to do any testing.

Thanks,
B. Witherspoon

possible fix

try this patch.  It should avoid this oops, but there may be other changes
required for that card.

Yes, this does avoids the oops. Thank you. The fb console works just it should.
As you expected there are still some issues with X. The issue is very much like
what I experienced without KMS and X when I was testing. I am not sure if this
is separate issue and another bug report should be filed or not. If so let me
know, but I will report what I have so far here.

Using:
libdrm-2.4.21
mesa-7.8.2
xorg-1.8.1.901
ati-drivers-6.13.0

After starting X I get a cursor and multi-color lines in the background. The
window manager and other apps are started, but are not visible. Attempting to
switch VT will cause the machine to lockup. It also seems that it will also
lockup after a few min even if nothing is done. Xorg.log doesn't have any
errors i can see but dmesg after X is started does have some *ERROR*. I have
attached both. The *ERROR*'s in dmesg are repeated until the machine eventually
locks. I was in a bit of a hurry to get the messages before it locked, so it
only occurs once or twice here. Without KMS the issue is almost the same, but I
get a nasty race condition prior to the lockup.

I will also attempt to get some sort of backtrace if it is helpful. I will need
to re-compile with debuging symbols. libdrm, mesa, xorg, ati-drivers should be
enough? I am not sure if gdb is going to be useful in this case but I am happy
to give it a run tonight.

You are getting a GPU lockup.  You might try:
Option "NoAccel" "True"
in the device section of your xorg.conf as a work around for the time being.

Also, what connectors does the card actually have on it?  DVI + VGA + TV?  DVI
+ DVI + TV?  We probably need a custom connector table for it.  Finally, can
you attach the output of lspci -vnn for the card?

Ah, I had tried NoAccel previously with limited success, however with your
patch applied it works much better. The window manager and apps are visible and
there is no lockup when I switch VT's. 

However, X does seg fault when I quit the wm. I have attached the backtrace
found the Xorg.log from that seg fault in case it is useful and the lspci
output you requested.

The connectors on the card are quite different from the generic connector table
the driver seems to use. The connectors are DVI + ADC (Apple Display Connector
DVI+USB for Cinema Displays; it was available prior to 2005). In case it is
relevant, I am currently using the DVI outpt with a VGA adaptor since I ran out
of DVI cables.

Please let me know if I can provide anything else.

That might be fixed in xf86-video-ati from git master.

As to the GPU lockup, You might try disabling EXA accel routines to see if you
can narrow down the problem.  E.g.,
Option "EXANoComposite"
Option "EXANoDownloadFromScreen"
Option "EXANoUploadToScreen"
in the device section of your xorg config.

We'll need to come up with a custom connector table.  I will need your help
testing to make sure I got the encoder and ddc line routing correct.

Actually, your lockups are probably AGP related.  Try adding radeon.agpmode=X
to your kernel command line where X = -1 or 1 or 2 or 4 or 8, e.g.,
radeon.agpmode=1
and see if any of those help.

Ok I will pull from the git tree and give those a try.

Changing the AGP mode did not improve any of the symptoms. Also disabling one
or all of the EXA options did not seem to help either. Adding an additional
"RenderAccel" "False" did show some of the wm but it would still lock. The
"NoAccel" option seems to be the only one that makes a difference. 

I am happy to test or help in anyway I can.

attempt to fix connector tables

This patch attempts to fix the connector tables.  We have 2 dacs, 2 tmds
controllers, and 4 ddc lines the could be configured.  Each DVI/ADC port is a
combination of 1 dac, 1 tmds controller, and 1 DDC line, so we need to find the
right combinations.

dmesg: first connector table patch

Ok, gave this table a try. I had to fuzz a few lines to get the patch to apply
to the 2.6.34 sources. I assume you must be working with some git branch. If it
would be best that I use the same source your working with let me know.

Attached is the dmesg. I noticed the connector_id is the same for both entries.
Are we testing with just one connector? The drivers reports that there is
nothing connected to the connector. I do not know how the Connector [0-1] are
enumerated, but I was unable to connect a monitor to the ADT port as I don't
have an adaptor yet. I ordered one though, so it should be here be the end of
this next week. 

I do not know of anyway to determine which physical connector this would be and
I assume if the dac,tmds or ddc lines or incorrect it might not be detected. Is
this the case?

Also if it is any use; the connectors appear to be DVI-D (Analog and Digital,
Dual link) and of course the ADT one has some additional pins.

I thought that was the case. We have two connectors now, but no input to the
monitor (atleast on the DVI-D output). So our controllers and ddc lines must be
wrong?

If no monitor is getting detected, the ddc lines are probably wrong.  In the
patch edit these two lines:

+        /* DVI - primary dac, dvo */
+        ddc_i2c = combios_setup_i2c_bus(rdev, RADEON_GPIO_DVI_DDC);

+        /* DVI - tv dac, internal tmds */
+        ddc_i2c = combios_setup_i2c_bus(rdev, RADEON_GPIO_MONID);

Make sure they are not the same value.  Try combinations the following values:

RADEON_GPIO_VGA_DDC
RADEON_GPIO_DVI_DDC
RADEON_GPIO_CRT2_DDC
RADEON_GPIO_MONID

When you get the right one, you should get an edid from your monitor assuming
it has one.

What I meant by "no input" is that the monitor is detected as dmesg does not
complain about no connected monitors and I am able to find the correct monitor
EDID in the /proc/devices-tree/pci@... directory, but the monitor doesn't seem
to be receiving input as it switches between digital and analog and then goes
into standby. So would this mean the dac and tmds controllers are wrong? 

The other night I thought I would do a little mix/match experimentation with
the different ddc, dac and tmds options you mentioned. I was able to find those
4 ddc symbols in the source and how I use them, but the dac and tmds lines I
have yet to figure out. It was getting late and I found the declarations I
need, but I have not yet been able to determine how to use them. I guess I need
some more examples.

I can most likely find the examples I need in the other tables we have here. I
have some time tonight so I will do some poking around.

Looking at the dmesg I see that the first connector actually has two dac
connectors and the second only has a tmds. Does this mean when adding our dac
encoder to the second connector we should pass ATOM_DEVICE_CRT2_SUPPORT for
supported_device instead of ATOM_DEVICE_CRT1_SUPPORT? I am unsure of that
function. I will attach the dmesg for you.

Making that change brings back video in fbcon, but the I have the same affects
when starting X. Locked...

Note, these patches will just fix up the connectors.  The GPU hang is another
issue.

Ok seems to work well. How will I know when we have the correct combinations
for the connector table? It seems that multiple combinations work.

Ideally you'd test both a digital and analog monitor on both ports and make
sure it works on each.  Can you attach your xorg log and dmesg from the final
version of the patch?  Also, make sure dpms works.  when X is running, try
'xset dpms force off' and make sure the montior goes off properly.

Sorry for the delay in my response. I have been preoccupied. 

I tested analog and dmcp works fine. However DVI has no output on monitor with
either connector.

What's dmcp?  With the analog monitor is the driver able to get an edid from
the monitor on both ports?  check 'xrandr --verbose' to see if there is an
edid.  If so, then we've gotten the ddc lines correct and the digital encoder
are probably reversed.

reverse digital encoder mapping

Does this patch help with the digital monitors?

Again I have to apologize. New that I am back home I was able to test this.
This patch fixes the digital monitors. I test analog/digital on the DVI port
and digital on the ADT port. The adapter I have is not compatible with analog.
An EDID is found on both and dpms works also.

Should this be marked resolved? I still have a seg fault when exiting X with
noaccel on and a gpu hang with it of. Should these be reported as another bug?

I've sent the connector patch upstream:
http://lists.freedesktop.org/archives/dri-devel/2010-September/003677.html

As to the hangs with accel, BenH was working on some fixes for that related to
the AGP bridge on macs.
