dmesg radeon 6850

I'm running Fedora 20 with the latest distro kernel (3.13.3).
I'm running Gnome shell and see very frequent hangs.
Its usually observed when the system has been inactive for a while
and the monitor goes into powersave mode. When I try to activate the
system via keyboard/mouse I get a black screen. I cannot switch to a VT as
well.
SSH still works and the system is responsive via ssh. DPM is not enabled.
However I did switch the card to "low" power profile after boot.

echo "low" > /sys/class/drm/card0/device/power_profile

cat /sys/kernel/debug/dri/0/radeon_pm_info
default engine clock: 775000 kHz
current engine clock: 99990 kHz
default memory clock: 1000000 kHz
current memory clock: 150000 kHz
voltage: 950 mV
PCIE lanes: 16

dmesg shows the following:

Does

 Option "ColorTiling2D" "off"

in xorg.conf work around the problem, or at least the error messages in dmesg?

I've disabled ColorTiling2D now. Will report back soon.
One observation is that when I disable monitor power saving in 
Gnome Settings (Power->Blank Screen->Never), I did not hit the issue.
Although I tested only for about 12 hours. Without this I usually get
the black screen on resuming the monitor from power saving mode in 
about 1 or 2 hours.

When you try switching VTs after the problem occurs, do lines like

 (II) AIGLX: Suspending AIGLX clients for VT switch
 (II) AIGLX: Resuming AIGLX clients after VT switch

appear in the Xorg log file? It sounds like maybe there's just a problem
lighting up the monitor again after it's turned off...

I can confirm that disabling ColorTiling2D had a positive impact.
There were no black screens on resuming the monitor from powersave mode.
I ran the system for about 14 hours. Then I turned ColorTiling2D back on,
and hit the issue within 5 minutes. The monitor power LED is on when resumed
and I can see the backlight. I tried switching to VT and still a black screen.
I do see (via ssh) the the lines you mention (in comment 7) in my xorg.0.log
when trying to switch VTs. Let me know if you want the full log, following is a
snippet from the log:

Does ColorTiling2D work better with a newer version of the mesa-dri-drivers
and/or libdrm(-radeon) packages?

--- Comment #10 from Nix <nix@esperi.org.uk> ---
FWIW, I have just started seeing behaviour very similar to this, also with an
HD6850, though it is probably a distinct bug because all the software versions
involved are very different. This happened after closely-adjoined upgrades of
the kernel (from 3.19 to 4.0.3), the X server (from 1.15.1, yes, I know, it's
because of the security holes I finally upgraded, to 1.17.1), the ATI driver
(from 7.3.0-26 to 7.5.0.68, all "git describe" output from the unmodified
trunk), Mesa (from 10.2.6 to 10.5.5), and LLVM (from 3.3 to 3.5.2), so the
fault could, alas, in theory lie in any or all of these. Mesa is using Gallium
in both cases. Glamor is not in use. dpm is, and has been working flawlessly
thank you very much, cutting my desktop's power consumption from 130W to 90W :)
over the last year that's saved at least the price of the beer I owe you for
the dpm work, Michel :)

With this setup, with an older Chromium (SVN revision 322707) I see very
frequent failures to map the interior of its windows at or shortly after
startup, sometimes accompanied by a total loss of the ability to switch focus,
whether by keyboard or mouse, whether on a desktop where the Chromium window
was mapped or not (X still responded, so I could switch out of X and kill
Chromium, whereupon X recovered). Chromium screams on its stderr as this
happens:

(There was nothing in dmesg when this happened.)

So far, so problematic. But I upgraded Chromium to r331233 today and it got
*ever* so much worse. The outward symptoms were the same -- until X crashed
with an obvious oops-I-didn't-check-errno error:

Fatal server error:
[354365.137] (EE) failed to map pixmap -22

In dmesg, we see rather a lot of complaining:

Following which the X server crashed, as above.

If I start Chromium with --disable-gpu, the problem goes away in both cases, so
the fault is likely either in Mesa or in the kernel or in the interaction
between the two. (I had the Chromium software rendering blacklist overridden
years earlier because it was trying to avoid problems that had been long fixed.
I've now reversed that decision, obviously!)

So it would probably be better to file your own report.

It would be great if you could narrow that down a bit. The r600g driver doesn't
use LLVM, so that's probably not it. I agree it's most likely between Mesa or
the kernel, or maybe xf86-video-ati.


> Glamor is not in use.

Have you tried glamor to see if it happens with that as well?

Does

    Option "ColorTiling2D" "off"

in /etc/X11/xorg.conf or the environment variable R600_DEBUG=no2d (or even
R600_DEBUG=notiling) for chromium work around the problem?

Sounds great, but I haven't done any DPM work, I think that beer would have to
go to Alex. :)

--- Comment #12 from Nix <nix@esperi.org.uk> ---
That's what I was afraid you'd say :)

I'll do some judicious downgrades (at least of the easy and
most-likely-relevant bit, the kernel) and file a better report. The other bits
are mostly coupled, so a kernel downgrade seems like a good place to start.

Found this Mir bug report - https://bugs.launchpad.net/mir/+bug/1144467

The fix is supposedly
http://bazaar.launchpad.net/~mir-team/mir/xf86-video-ati-vladmir/revision/2538

I dont know if this has been upstreamed. Posting it here to see if Michel gets
any clues seeing this. I don't see the original problem anymore, but I do get
the same issue reported here -
https://bugs.freedesktop.org/show_bug.cgi?id=90406  with the latest Arch linux
build.

AFAICT we mostly have equivalent changes already. The only thing that might be
missing is setting the pixmap pitch to what radeon_bo_get_tiling() returns.

That's a different issue I think. Resolving this report as fixed, thanks for
the followup.
