            Bug ID: 112491
           Summary: Radeon: HD 7400G / A4-4355M System overheats with 3D
                    graphics active.
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.2
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: djtm@gmx.net
        Regression: No

I've already tried several radeon boot flags, such as DPM on and off, BAPM on
and off, without success. The problem does not occur with the fglrx or Windows
driver. I'm using glamor acceleration. I'm using an external 4k display in
FullHD resolution, the internal laptop display is disabled.

I've read similar bugs here:
https://bugzilla.kernel.org/show_bug.cgi?id=63101
https://bugzilla.kernel.org/show_bug.cgi?id=68571
https://bugs.freedesktop.org/show_bug.cgi?id=73053

But I'm not sure which of the tips are still relevant in the current tree?

The results are:
Playing a simple car racing game, I can do:
dpm=0 -> 2 laps, then the system shuts down due to thermal zone overheating
(regular shutdown, not suddenly).
dpm=-1 -> ~1 lap, the system suddenly turns off hard without warning.
bapm=1 -> ~1 lap, hard turn off

dmesg 4.2 bapm=1 hang on radeon load.

This is a time where the system hung up already during boot with bapm active.
That doesn't always happen, though.

3D is used for everything (even "2D" apps).  Is the problem specific to this
car racing game?  It might be a bug in the mesa driver which causes the GPU to
lock up.  Also make sure the fan and heatsink are free of dust.

No the problem occurs with any 3d load, just not with 2d load usually. Maybe
even glxgears is enough. 

Yes I've cleaned the fan and heatsink area. Didn't help. :/

Actually, I forgot to mention I used to have problems without active 3D use as
well, but I'm now switching the DPM profile to battery during boot. And that
solved that part mostly. Also, high CPU use by itself is not a problem. Where
not using DPM, I didn't switch to the battery/low power profile.

Temperature Graph 1

I'm having some doubts about the temperature hypothesis now. With DPM active,
there seem to be higher temperatures during boot up than during the freezes or
reboots. (visible by the gaps, 5 seconds intervals between measurements).

So with DPM there seems to be another issue than without it. I've tried
disabling hyperz, to no avail.

It looks like with BAPM it might more likely be overheating. But I can't
reproduce the lockups/sudden reboots at all at the moment.

Booting with radeon.hard_reset=1 I get this error at the point where I usually
get a hang:
GPU lockup (current fence id 0x0000000000004aa1 last fence id
0x0000000000004aa8 on ring 0)

If you'd like any information please let me know now. Because it seems there is
not much interest in finding the problem. So I'll have to and will switch back
to the proprietary driver.

(It turned out that I used a different version of the game which crashed the
card instead. I get the hard off also without any parameters btw.)

[Wonderful, fglrx doesn't work at all with kernel 4.2... ...]

The fastest way to get the system to overheat is to
- enable redshift (or probably xgamma)
- disable vsync
- set dpm to preformance*
echo performance | sudo tee /sys/class/drm/card0/device/power_dpm_state
- activate cpu turbo mode*
echo 1 | sudo tee /sys/devices/system/cpu/cpufreq/boost
- activate BAPM
- activate DRI3
- stay in the game menu (tested with blazrush, kotor)

* Here the effect is not that certain/serious.

Things that help to avoid overheating:
- boot with nomodeset radeon.modeset=1

#vblank_mode=0 glmark2 --run-forever 
does not cause a hang, some of the tests seem less demanding, so the
temperature does up and down.

GALLIUM_HUD=temperature is helpful to watch how fast the temperature clims.

So the problems are worse as summer approaches. Still present in 4.6. The
system also shuts down hard with vdpau video playback. The weird thing is that
the hard shutdowns occur at a lower temperature if dpm is active than if it
isn't. 

Any hints for debugging this?

So, OpenGL and VDPAU crash the GPU. Any chance you could also test OpenCL? Not
sure if [1] works on R600 OpenCL, but [2] does.

I think I've solved it. 
The kernel parameter 

radeon.runpm=0

seems to work around the issue. The performance is degraded, but the
temperatures mostly stay below 80°C. Generally the system appears to stay much
cooler.

Is this a multi-GPU notebook?  That option only affects Hybrid laptops with
multiple GPUs.
