Under v4.8-rc, behaviour is different: bios_limit goes to 1GHz there when temperature is around 84C at the thermal zone. That keeps ibm/thermal temperatures under 90C, and no "thermal emergency" messages in syslog. So we seem to have thermal or ACPI regression in v4.9-rc3.

So v4.9 thermal management does not work. v4.8 passive thermal management works _too well_, keeping fan at cca 3200 rpm, far below 3700 rpm it can reach. CPU is getting throttled, and fan is not even running at full speed. I can manually control the fan with thinkpad_acpi.fan_control=1... I guess I can write some scripts?

Can you add either add printk in acpi_processor_ppc_has_changed() or use ftrace and see do you get to these functions acpi_processor_ppc_init() acpi_processor_ppc_has_changed() acpi_processor_ppc_notifier() ? When temperature limit is reached acpi_processor_ppc_notifier() should be called. Thanks, Srinivas |

Hmm, thanks for the pointer. But it seems like I'll have to build my own, as /proc/acpi/ibm does not follow the usual infrastructure...

Also try Don't run workload, just on an idle system. # echo 1 > /sys/class/thermal/cooling_device2/cur_state monitor the scaling_max_freq, it should reduce # echo 2 > /sys/class/thermal/cooling_device2/cur_state monitor the scaling_max_freq, it should reduce Thanks, Srinivas |

I sent some suggestion to try in previous email to add more prints and enable debug in acpi-cpufreq. Let's try that first. We need to fix anyway even if 4.8-final has this issue.

Try them instead, please. Also, thinkpad-acpi will report the EC thermal sensors. They don't need to (and most often won't) match whatever you read from the processor core(s). -- Henrique Holschuh |

It is the second-level alert that the ThinkPad is about to catch fire. It should have logged a "is too hot!" first-level alert earlier, but this depends on the EC and not the driver. Maybe the temperature raised too fast. In Windows, the system would attempt to hibernate or shutdown. I would be quite happy to have thinkpad-acpi trigger such behavior as well, patches (or guidance) are welcome ;-) Anyway, if that temperature goes about 1~2°C higher, the EC should cut power to your motherboard. Apparently, the built-in thermal protection clock modulation on the Intel processor is somehow saving your box from that forced power-off. -- Henrique Holschuh |

Maybe the temperature raised > too fast. I don't think I'm seeing the "is too hot" messages. Actually.. even the "THERMAL EMERGENCY" messages seem to have too low severity, so they are hidden in syslogs -- they don't go to all the consoles. > In Windows, the system would attempt to hibernate or shutdown.

Actually, the machine _will_ shut down some time after that. It seems that one of acpi trip points jumps to 128C which forces shutdown.

I don't like the idea of touching vendor-screwup-land like thermal zones, especially when thinkpads *already* have thermal zones and they must come from the very same sensors... This would need a lot of careful studying and planning. > Is it known what various fields in /proc/acpi/ibm/thermal measure? It varies with each model. You can map it out with better precision by using a cold spray while doing an "open-heart" surgery on the thinkpad. I kid you not, that's how they were mapped for some models. Look for information about this in thinkwiki: http://www.thinkwiki.org/wiki/Thermal_Sensors#ThinkPad_X60 The battery-pack-related sensor that is stuck at 50°C is something the Lenovo Yamato labs guys wouldn't be clear about. They told me to look at what the Windows drivers do, but that would require (1) Windows in the first place, and (2) clean room reverse engineering protocols. > Basically... 100C is okay for semiconductors, but I'd prefer not to > kill the hard drive.... Well, that first sensor getting to 100°C is your CPU for sure. > > thinkpad-acpi is supposed to export standard hwmon temperature sensors > > as well. Try them instead, please. > > Heh, I just finished python to work with /proc/acpi/ibm. Oh well. Hey, I *did* properly document that driver, and the documentation is even mostly up-to-date... Please refer to Documentation/laptops/thinkpad-acpi.txt in the kernel tree. -- Henrique Holschuh |

Ok, burnP6 pushes cpu to 102C rather quickly. dmesg is below.

Hi! BTW.. This machine has nasty habit of hanging during kernel boot when it is "hot".. which makes reboots unplesant here. Ideas would be welcome how to debug that.

Hi! Thanks to Srinivas, bug tracking moved to bugzilla at https://bugzilla.kernel.org/show_bug.cgi?id=187311 , it is regression from v4.8-final. Easiest way to observe it is that cpufreq/bios_limit does not change in v4.9, where it goes lower with high temperature on v4.8.

Hi! Bisection was not fun, but I've got the result: # first bad commit: [6ea8c546f3655a81f82672f24b66dad6095bdd07] ACPICA: FADT support cleanup I've reverted the patch on top of 4.9-rc4, and thermal management now works. More details are in https://bugzilla.kernel.org/show_bug.cgi?id=187311 As this breaks thermal management on both thinkpad X60 and T40p, can I ask for a revert? If you have other ideas, I can test them, but as this is just a cleanup, it can wait for 4.10... Thanks, Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html |

Right. Besides, we're in the -rc6 time frame now, so I'll queue up a revert. Thanks, Rafael |
