[Lenovo ThinkPad T420] Graphics performance reduced after playing games for a little bit

[Shuhao]

I recently upgraded to Saucy. I noticed that everytime I play something like Counter Strike Source, my graphics performance drops down to something like 15fps while normally it is locked at a max FPS of 40fps..

This slowdown happens and also makes my computer generally pretty slow. Thermo maximum has not been tripped (I know, and I actually underclock while playing these games).

I'm not sure why this is happening. It only happens on 13.10. I have bumblebee installed. I used both cards to play the game and the same thing happens

[Shuhao (shuhao)]

So I think I have an idea of what is happening..

Here's my sensors output:

acpitz-virtual-0
Adapter: Virtual device
temp1: +56.0°C (crit = +98.0°C)

thinkpad-isa-0000
Adapter: ISA adapter
fan1: 1978 RPM

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +57.0°C (high = +86.0°C, crit = +100.0°C)
Core 0: +50.0°C (high = +86.0°C, crit = +100.0°C)
Core 1: +53.0°C (high = +86.0°C, crit = +100.0°C)

pkg-temp-0-virtual-0
Adapter: Virtual device
temp1: +57.0°C

The "high" temperature is at 86C. I notice the performance drop at around 87C. (Still need to try to reproduce it again...)

The CPU clock frequency is not modified at 87C. The characteristics of the performance drop is consistent with a lowered "Clock modulation", something I've seen in programs that controls the CPU on windows.

Now this did not happen on a previous version of Linux. Previously when I hit about 95C (which apparently is quite common for these laptops after about 1-2 years of usage), the CPU frequency will be restricted to 800MHz, which would be the lowest frequency available.

So I'm not exactly sure what the best fix for this would be, or where the "regression" happened. While 95C does not seem like a good idea, it is actually quite easy, at least for me, to hit 87C on these thinkpads, even after cleaning it out, replacing the thermal paste (multiple times with no difference in results), and so forth.

I will try to get myself a fan mat and see if that helps things sometime soon and confirm that this is indeed the issue.

[Chris Wilson (ickle)]

*** Bug 70594 has been marked as a duplicate of this bug. ***

[Shuhao (shuhao)]

Does anyone else here experience CPU/GPU performance drops when they experience these hangs?

I think these are due to overheating but I can't be sure as the clock freq of the CPU is not being limited. Previously, that happened when I hit 95C, where as these slow down happens when my core hits roughly 86C.

Laptop is a Thinkpad T420. Critical temp is 100C. It's been documented that these laptops will hit these temperature after computationally intensive tasks such as games.

> experience these hangs?

It takes up to a few seconds for the kernel to detect a hang (the gpu doesn't really tell us, it simply stops doing stuff). So frame-freezing while that happens is completely expected. And we also need to turbo-up the chip again, which in some pathetic corner-cases also takes a while. 3.13 has some cool tricks from Chris to help with the turboing.

[Shuhao (shuhao)]

Would a freeze that requires hard reset be also part of this?

I just had one shortly after a short hang.

Syslog got a bunch of nul at the end before the reboot.

These patches seem to work. I've been playing DOTA2 for the last 3 hours without problems. It used to hang every 8-10 minutes.

I'll post if it hangs again.

I just read the news at http://www.phoronix.com/scan.php?page=news_item&px=MTQ5Njg, which says "Kenneth's patches don't appear to eliminate the driver issues but rather allow DOTA 2 to run for about three hours before hanging."

Sorry for the misunderstanding I caused, apparently my English is too bad to deliver. That was not what I meant to say.

The hanging didn't happen again! The patch was good! I played DOTA2 for 3 hours before I stopped playing. NO hanging, so I felt it's time to let Kenneth know the patch worked. Since 3 hours' testing wasn't conclusive enough, I added "I'll post if it hangs again".

I hope this clarifies. I'll try to contact phoronix to let them know too.

P.S I played more DOTA2 today. Good news: still no hanging. Now I have been testing the patch for about 10 hours so I can conclude with 99% confidence that the patch fixes the problem.

P.S2 https://bugs.freedesktop.org/show_bug.cgi?id=69379 seems to be a duplicate. One of you mesa knowledgeables can check on that.

[Kenxeth (kenxeth)]

No, I understood you perfectly. Don't worry about it. Thanks again for testing!

intel_gpu_abrt.tar

Hi,

Update on the testing on patch.. Hanging occurs again. It happens when I was watching video using flash. My KDE setup uses OpenGL 2.0 Raster for desktop effects, if that's relevant.

I'll attach intel_gpu_abrt.tar

Maybe that's a different bug? Or maybe I just did something wrong. This is my first time compiling an important Linux component, and it's a possibility I didn't do things 100% right.

[Kenxeth (kenxeth)]

That's a different hang - it hangs on MI_SEMAPHORE_MBOX. Based on Daniel's recent mesa-dev post, I believe it's bug #54226.

[Kenxeth (kenxeth)]

I've pushed the following fixes to Mesa master:

commit 5563dfabc8c1b7cc1a67e4d64311ea29aef43087

    i965: Emit post-sync non-zero flush before 3DSTATE_DRAWING_RECTANGLE.

commit 436e815a250a8fde22d79093f4b9eed56472693b
Author: Kenneth Graunke <email address hidden>

    i965: Emit post-sync non-zero flush before 3DSTATE_GS_SVB_INDEX.

commit 32a3f5f6d768e5828be1d1f46b1b3f819f55cba8
Author: Daniel Vetter <email address hidden>

    i965: CS writes/reads should use I915_GEM_INSTRUCTION

These should be in Mesa 10.0. I've also marked them as candidates for a 9.2 stable release, but we may want to let them sit on master for a little while to make sure they don't cause other hang problems.

Marking Resolved/Fixed. Thanks for your patience, all.

[Shuhao (shuhao)]

For ubuntu users, this might help you: https://launchpad.net/~oibaf/+archive/graphics-drivers/

It is available for 13.10 and seems like it compiled the oct 31st version of mesa, which is after when this patch landed on master.

[Shuhao (shuhao)]

I can tentatively confirm that this is working for me as well.

Will run some more tests later.

[Greatquux (greatquux)]

I still experienced a hard crash of the entire system when bringing up a complex page in Google Maps, even with this installed. So I've taken to disabling all acceleration (NoAccel "true") - I definitely do not see the issue then (although of course scrolling in Google Maps is slower, it does not crash the machine).

[Mrsteven (mrsteven)]

I can confirm that the patches in Comment 20 help a lot. In my case the gpu hung while playing MegaGlest 3.7.1, SuperTuxKart 0.8 and sometimes also while scrolling in LyX and Firefox 17.0.9 (using KDE with compositing enabled).

I haven't tested LyX so far, but the freezes in the other programs seem to be gone. Of course this does not mean that there can't be another bug somewhere (which might be the case in Comment 23).

[Januszmk6 (januszmk6)]

I also confirm that after compiling mesa 10 (and patching xorg-server for new mesa) it's working fine, no gpu hang

[Greatquux (greatquux)]

I just re-installed oibaf's PPA and reproduced a GPU hang in Google Maps. It didn't crash the first time, but I know that if I continue scrolling in Google Maps it will bring down the whole system. However here's the message from syslog and the associated i915_error_state file will be attached.

This is the i915_error_state file after updating my system with the https://launchpad.net/~oibaf/+archive/graphics-drivers/ PPA (and restarting X of course) and scrolling around a lot in Google Maps in Google Chrome.

A hang in the bsd can't be a mesa issue. Also since it's inside the batch it's not one of the known kernel issues. Please upgrade libva (only thing that uses the bsd ring) and if it still fails fail a new bug against lib.

i915_error_state

Still hang after playing hedgewars for nearly an hour, but it doesn't hang continuously, just one time. Dmesg shows:
[ 3929.521951] [drm:i915_hangcheck_elapsed] *ERROR* stuck on render ring

[ 3929.521967] [drm] capturing error event; look for more information in /sys/kernel/debug/dri/0/i915_error_state

I notice that my error message has "blitter ring". Is it a different bug?

[Yjcoshc (yjcoshc)]

I have compiled Mesa 10 master in /opt/mesa and added a conf file in /etc/ld.so.conf.d.
Now glxinfo shows:
OpenGL version string: 3.0 Mesa 10.0.0-devel (git-69b425e)
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
This is the first time I have built mesa.

Yes, IPEHR of 0x0b160001 suggests that your bug is actually:
https://bugs.freedesktop.org/show_bug.cgi?id=54226

It is not this bug.

[Kenxeth (kenxeth)]

Fixed in Mesa 9.2.3 (out today), the upcoming Mesa 10.0 release, or Mesa master.

This fixes the Sandybridge-specific GPU hang where i915_error_state (aka /sys/class/drm/card0/error) lists an IPEHR of 0x79050005.

If you experience a GPU hang and your IPEHR is not 0x79050005, that is a different bug.

Thanks again for your patience!

[Greatquux (greatquux)]

Sorry to re-open but I wanted to include one more detail - either a recent update fixed this for me, or a recent change I made to my BIOS settings (changing my fan speed from "normal" to "turbo" in my motherboard BIOS) has made me unable to reproduce this hang, even after long periods of scrolling complex maps in Google Maps. I can definitely raise the temperature nearly 10C by doing this, but with the fans on turbo (and this only seems to make it slightly louder) the hang does not occur. Hopefully this will help anyone else with these issues - always try to cool the processor as much as possible!

[Eric Branson (esbranson)]

This should be confirmed (it is not affected by the kernel version), and marked as affecting Saucy and Trusty because they both use the Mesa 9.2 series so both Saucy and Trusty get updated to Mesa 9.2.3 as noted upstream.

[Eric Branson (esbranson)]

The bug has been confirmed by Mesa upstream for all versions prior to 9.2.3.

[Shuhao (shuhao)]

Yeah this is definitely a mesa problem. Any idea when this will be pushed to saucy's repo? I have computers waiting to be upgraded to 13.10 due to this instability.

[penalvch (penalvch)]

shuhao, as per http://download.lenovo.com/express/ddfm.html an update is available for your BIOS (1.46). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Thank you for your understanding.

[Tino Werth (tino-werth-r)]

I have the same problem.
Notebook: Lenovo T420, Intel HD Graphics 3000

After starting Ubuntu everything works fine. If I use Google Maps in Chromium/Firefox or working some time with LibreOffice the graphic begins to stutter. Even if I only move a window for one end of the screen to the other it jerky (anything but smoothly).

Yesterday I updated the BIOS to 2013-07-05 (latest version) but it did not help.

The only thing that helps is a reboot.

Please let me know if you need more information.

Best
