Description Guillaume GARDET 2019-11-18 13:03:40 UTC

While using HiKey960 with Tumbleweed with only 'zypper in <some_packages>', I quickly get:
  hisi_thermal fff30000.tsensor: sensor <1> THERMAL ALARM: 65370 > 65000

If I blow on the heat sink, temperature goes down quickly and I get:
  hisi_thermal fff30000.tsensor: sensor <1> THERMAL ALARM stopped: 61065 < 65000

It seems to be a known issue. Not sure if some software could help here.

We already have:
* cpufreq_dt is set on 'ondemand' for policy0 and policy4
* thermal policy is 'step_wise'

Forgotten bug, sorry about that.

First, does it still happen with newer TW kernels?

Adding Petr if he could find someone in his team to take a look...

Closing. No response.
