            Bug ID: 68571
           Summary: GPU lockup on AMD Radeon HD6850 with DPM=1
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.13-rc6 / 3.12
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: kilobug@kilobug.org
        Regression: No

Hi,

When using dpm with my Radeon HD6850 I get frequent "GPU lockup", with the
screen freezing for a few seconds. Sometimes (but not often) the system
completely freezes (hard reset required). It happens both during playing OpenGL
games and during normal (not GPU intensive) activities, slightly more often
during games.

I have the issue with both kernel 3.12 (manually enabling the DPM) and 3.13-rc6
(in which it's enabled by default). With DPM disabled, all is working fine. I'm
using Mesa 10.0.1, but had the problem with Mesa 9.2.2 on kernel 3.12 too
(didn't try Mesa 9.2.2 with kernel 3.13-rc6).

I'm using Debian GNU/Linux 64-bits, all packages are from the Debian archive
(Mesa 10 and Linux 3.13-rc6 from experimental), but I don't think the problem
is Debian-specific so I prefer to report it here.

I include a "dmesg" containing two of those lockups.

The card itself is a Saphire HD6850 with 1Gb of GDDR5 memory, the CPU is a
Intel(R) Core(TM)2 Duo CPU E8400, memory is 2x2Gb of DDR2, the motherboard a
ASUSTeK P5E3. 

Feel free to ask for any additional information, or any test I could perform.

Regards,

Sorry, but it seems even worse : I get the "lockup" as often, but it doesn't
recover from it anymore. Either the system fully freeze after a lockup (with
garbage on the screen), or it keeps freezing and resetting in loop.

By switching to VT1 after a freeze I managed to do a dmesg while it was in a
freeze/reset loop.

With dpm=0 it works fine on your branch (like it does on the 3.12 or 3.13-rc6).

PS : I get the version string "3.13.0-rc4+" with your branch, is that right or
did I use the wrong version ? I got it with "git clone
git://people.freedesktop.org/~agd5f/linux" and then "git checkout
drm-next-3.14".

Yes, that is correct, it's based on Dave's drm-next branch.

--- Comment #10 from kilobug@kilobug.org ---
I tried the patch, with various kind of programs (3d games, 2d games, desktop
apps, mplayer, ...). It worked somewhat better, but I still got some lockup
with some programs (I'll send the dmesg), and even some complete freeze (like
while playing a video with mplayer).

If needed, I can try to make more tests with various programs (games, phoronix
test suite, ...) and give the result (works well, lockup but recovery, freeze)
depending on the program. But they'll take some time (since I'll need to reboot
quite a lot), so I'll only be able to do it during the week-end, and only if
it's useful. Also, should I limit myself to free software, or should I include
some non-free games in the mix ?

Does disabling hyperZ help?  E.g., set env var R600_DEBUG=nohyperz in
/etc/environment or however your distro handles global env vars.

I tried, didn't help. I also tried disabling the "R600_DEBUG=sb" that I had
there, didn't help either.

Note : I tried both with the patched drm-next kernel, should I try with another
build ?

dmesg with two gpu lockups

Hi,

i think i got the same problem with kernel 3.13 on an arch distro and dpm
enabled.
GPU is a MSI 6870 hawk.
Here the output of dmesg after two gpu locks.
A small hint: it almost always happens when playing a video (mplayer or
browser).

No problems if i append radeon.dpm=0 at the kernel command line.

I forgot to say: the problem started after i switched my board & CPU a week
ago.
Now i use a gigabyte h87-hd3 board with an intel xeon e3-1230v3 CPU. Before it
was an AMD CPU with an Foxconn A7DA-S board.

Maybe it has something to do with the switch from PCIExpress 2.0 to 3.0?

I have a PCIExpress 2.0 board (and the lockups), but I have an Intel CPU. Not
sure it could be linked to Intel CPU vs AMD CPU, or something else related to
the motherboard. I can include a dmidecode output if it can be of any use.

You are right, its not PCIExpress 2.0 vs. 3.0. I forced it in the bios, no
improvment.

I also tried the drm-next-3.14 branch from Alex repository. Made it even worse:
freeze on boot. Before i reached kdm and sometimes i saw the desktop.  
After applying the patch from
https://bugzilla.kernel.org/show_bug.cgi?id=68571#c5 i am on the same behaviour
like i was with stock kernel 3.13.

I discovered that there is no kernel panic. I can get back to KDM with the
SysRQ keys (Alt + Print + K).

Maybe its because my card is slightly overclocked by the factory:
http://msi.com/product/vga/R6870-Hawk.html (in compare with the reference card:
930Mhz vs 900Mhz).

Something else i can do?

I may be wrong here, but I think that for now (which is something I worked with
Alex Deucher in a different bug), overclocked cards are being limited to the
reference values.

That's no problem, as long as they are stable :).
But i think you are wrong: in the dmesg output the card is set to 930 Mhz (if i
read it correctly). And the stock 6870 uses 900Mhz. Maybe the voltage is not
adjusted correctly? Whats the effect of an undervolted card?

Yes, but if I remember correctly again, the real values are not printed out in
kernel <= 3.13 if they were limited. I think I've seen a patch from Alex or
Christian about that so we can have the real values in kernel 3.14.

Otherwise, I could provide you a patch of mine that gives the real values used
(it's printed as a warning saying the values have been limited to X). I'm
experiencing similar problems with my HD6950, that's why I've been digging on
my side.

There is no overclocking on my card, reference HD6850 is 775Mhz (accoring to
http://www.amd.com/us/products/desktop/graphics/amd-radeon-hd-6000/hd-6850/Pages/amd-radeon-hd-6850-overview.aspx#2)
and the Sapphire has the same frequency, according to both Sapphire website
(http://www.sapphiretech.com/presentation/product/?pid=497&lid=1) and the
radeon-profile utility.

DPM is enabled by passing radeon.dpm=1 to the kernel paramters:

root@perry64 # cat /sys/kernel/debug/dri/64/radeon_pm_info
uvd    vclk: 0 dclk: 0
power level 2    sclk: 93000 mclk: 105000 vddc: 1185 vddci: 1150
root@perry64 # cat /sys/kernel/debug/dri/64/radeon_pm_info
uvd    vclk: 0 dclk: 0
power level 0    sclk: 10000 mclk: 15000 vddc: 950 vddci: 950

And no locks since two days.

There was also a dpm restructuring in 3.14 that may have helped, but as
reported in comment 4, it didn't seem to help kilobug.  You could try
bisecting.

I also tried the drm-next-3.14 branch mentioned in comment 3 and got the same

I tried the drm-fixes-3.14 branch, but it didn't work better for me - playing a
video with mplayer freezes the system in less than one minute (with
radeon.dpm=1). I didn't run any other test with it.

If needed, I can run more tests during the week-end, but I don't know what kind
of tests could be useful.

Sorry I'll be abroad until the end of March and I won't be able to access the
computer with the HD6850 (except through ssh, but hard to test video card that
way...), I'll test that when I'm back, probably during the 29-30 week-end.

So, I finally could perform some tests. Two notes first :

1. Meanwhile I upgraded to Mesa 10.1.0.

2. The patch seemed to be already included in the drm-fixes-3.14 branch, so I
just tested with the latest version of that branch.

Now the tests themselves :

1. With dpm=0 and hyperz enabled, the drm-fixes-3.14 branch is stable.

2. With dpm=1 and hyperz enabled on Mesa 10.1, both the drm-fixes-3.14 and the
vanilla 3.13 would freeze at boot (when loading the display manager, lightdm).

3. With dpm=1 and hyperz disabled, they would work for a while, but as
initially described on this bug, after a while they freeze or lockup. The most
secure way I found to trigger a freeze is to play a HD movie using the "gl"
output of mplayer, with that, it freezes in a few minutes.


@Mihai : I'm uploading my build of the drm-fixes branch (which I wrongly named
drmnext, but it's really the drm-fixes branch... sorry, but I didn't rebuild it
just to fix the name...) on http://kilobug.net/debian it's for Debian not for
Ubuntu but it *should* work on Ubuntu too.

With DPM=1 I still get gpu lockups with 3.14rc8 and mesa 10.2~git1403270730. It
locks up with black screen or a pattern after a few minutes of playing OpenGL
games or playing videos with VDPAU. I don't recall ever locking up in normal
desktop use.

I changed my motherboard and CPU today (went from Intel to AMD CPU), but it
didn't change the issue at all. I still get a freeze very quickly when playing
a HD video on mplayer with the "GL" video output with dpm=1, but it works
smoothly with dpm=0.

Is there any additional information I can provide to help ? Would a dmidecode
of the new motherboard by of any help ? Additional tests ?

had the same issue over here. switched over to 3.14.2 which fixed the problem
for me.

maybe that's an option for you :)

I still have the problem with 3.14.2. Are you sure you enabled dpm ? Due to
this bug, dpm is disabled by default on 3.14 for this chipset, you need to
force it enabled.

Hello kilobug,

Alex marked my bug (https://bugzilla.kernel.org/show_bug.cgi?id=78321) as a
duplicate. And my solution is to disable the hdmi audio output. 
You can do this by appending radeon.audio=0 to the kernel parameters or just
blacklist the snd_hda_intel and the snd_hda_codec_hdmi modules.

I tried with audio=0 with 3.14 and 3.15-rc8, and it's slightly better, but
there are still freezes.

X doesn't crash at startup anymore even with hyperz enabled, but using an
OpenGL game or playing a HD movie with mplayer ends up with a system freeze
after a while, with hyperz enabled or disabled.

I'm experiencing the same problem with a XFX Radeon HD 7870 GHz Edition.  I've
tried both appending radeon.audio=0 to the kernel parameters and blacklisting
snd_hda_codec_hdmi to no avail.  Currently, I'm on 3.15.1, but I remember it
happening on 3.14, too.

You have different hardware.  This bug is specific to BTC parts.  You have an

I am experiencing the same problem with my Radeon HD7770. I've added
radeon.audio=0 to no avail. I'm on the 3.15.1 kernel now too, but it happened
in kernel 3.14 too! It's driving me crazy.

After testing radeon.audio=0 a few days, i have to say that the bug still
remains. But there is definitely a correlation between the hdmi audio and this
problem as the things are getting better with audio=0.
The X server often freezes on startup but after a successful login i can work
without problems.

Can not confirm. X stills freezes with latest kernel from git.

Another hint: radeon.audio=0 and blacklisting the snd_intel_hda modules are not
the same. If i remove the modules the problem disappears, but i still get the
freezes with radeon.audio=0.

Two different voltages.  vddc is the core voltage.  vddci is the voltage
related to the memory interface.

I tried the patch on the "drm-fixes-3.16" branch, but I got the same result :
freeze after a while when playing a movie on mplayer -vo gl (that's the most
reliable method I found to get the freeze), same with hyperz enabled and
disabled (I still have radeon.audio=0).

Are you sure you got the right branch?  I pushed a testing branch containing
the patch to drm-fixes-3.16-wip

Log file after i boot Windows 7

Hi again,

the bug is still not fixed for me. I still get a freeze when login in to KDE.

But i did some research why it worked flawless yesterday: I use a dual boot
system on my PC and if i first start Windows 7 and then do a reboot into Arch
Linux everything works fine. But if i power off the system for some hours and
directly boot into Arch i get the freezes again. And i can reproduce this
behavior (did it three times). 

I tried to get the difference between both boot logs. Is there something else
that can help?

Ok, that's fine.  no need to try the -wip branch directly if you already tried
the patch.

That panic is fixed in the current drm-fixes trees, and hopefully soon in
Linus' tree.

Great news !

I tried the -wip branch, and so far no crash (with and without hyperz). I will
keep running it and see how it works. I'll do more tests during the week-end,
and hopefully they won't crash.

I don't know if I fumbled in applying the patch manually (would surprise me,
but not impossible) or if there is another fix in the branch.

I did more tests, and it's much better, but still not perfect.

During GPU-intensive tasks (movie playing, Unigine benchmarks, a full Civ5
game) it works all well. But during non-GPU tasks (browsing the web, IRC,
editing text) I got a few freeze.

The freeze doesn't seem to be complete (all the GUI freezes, but the rest seems
to be still working at least for a while), I'll try to get logs/dmesg through
ssh, but my laptop died a few days ago so I can't right now... I'll send more
information as soon as I can get it.

So I did a bit more tests, I had a few freezes mostly in non-GL tasks
(terminal, ...). SAK does work to kill X and reset the card, thanks perry3d for

I just had my Sapphire HD 6870 (Dirt3 Edition) successfully reset itself after
a lockup for the first time (as opposed to the usual black or funnily patterned
screen), so I can post my dmesg. Gaming seems to work without a hitch (played
through The Swapper in one go), but doing anything which uses the UVD seems to
be a ticking time bomb.
(Yes, Magic SysRq keys work usually after a lockup.)

If there is any additional data that would help to debug this, please tell me
how to provide it...

Hello,

This bug is still present on Debian unstable, I had it again yesterday; it

reappears garbled, alternates between blank and garbled a few times, and if I
don't reboot quickly enough, I seem to recall (not sure about this one) that
the whole system may crash in a way that requires a hard reset.

If there is something I can test to help solve this bug, please say so. I
wonder if there are graphics adapters with decent OpenGL support using free
drivers that don't suffer from this kind of bug...

Thanks

For information I just changed my GPU to a brand new R9 380X (which uses the
amdgpu driver), so I won't be able to easily do more tests on this bug - I
still have the 6850 in a box, so if you're pretty sure it's fixed I can swap
the card and swap it back, but it's a "delicate" operation so I won't be able
to do it frequently.

Hi!

I have HD 6850 and Kernel 4.4.14.

This problem appeared for me when I changed rootflags.
Solved with rootflags=relatime,lazytime,commit=60 in kernel parameters.

HTH

Best regards
Weber Kai

Forgot to mention: And relatime,lazytime,commit=60 in fstab
I believe maybe dpm need some fs information to work well.

dpm has nothing to do with the filesystem.

I think so as well...

Anyway before, I had to put this in kernel parameters, or else, black screen
and hang up during boot:
  radeon.dpm=0

And since I put this in grub.cfg and fstab, never had a black screen again:
  rootflags=relatime,lazytime,commit=60 iommu=noagp radeon.dpm=1

I don't understand why, but it worked...
I have pcie XFX HD6850 AMD 1055T FOSS drivers, kernel 4.4.14 .

Maybe it could help you to troubleshoot this error too.
I think it's worth a try, if you have spare time.

If this don't help you... Then I'm sorry...

It could be iommu=noagp, at least that would make more sense than filesystem
flags...
