description |
There are some new fanless platforms use DPTF's virtual sensor instead
of INT340X devices.
Because of that, the _PSV is no longer in use, at least not directly,
hence its value may set higher then _CRT. To a fanless system that means
no cooling device gets activated before _CRT, so the system will be
considered overheated by Linux kernel, and gets shutdown by the kernel. |
== SRU Justification, Cosmic, Bionic, Xenial ==
There are some new fanless platforms use DPTF's virtual sensor instead
of INT340X devices.
Because of that, the _PSV is no longer in use, at least not directly,
hence its value may set higher then _CRT. To a fanless system that means
no cooling device gets activated before _CRT, so the system will be
considered overheated by Linux kernel, and gets shutdown by the kernel.
== Fix ==
Upstream fix https://github.com/intel/thermal_daemon/commit/97976782dd26b4d592ccb97eb89c2a3a871a22a9
== Testing ==
Exercise CPUs on a fanless INT340X device with _CRT ACPI objects and try and reach the trip point. Without the fix thermal overrun occurs and this trips CPU shutdown. With the fix, thermald will start to throttle the system and get it out of the thermal overrun zone.
== Regression Potential ==
This modifies the behavior for just INT340X devices with ACPI _CRT objects, specifically, now to honor this setting. This is a small subset of devices with these objects and the change will in face make thermald catch systems before they hit thermal overrun, so the risk of regression is small. This fix also has been reviewed by the thermal experts at Intel, so it seems like a very reasonable workaround for these specific use cases. |
