@waveform I'm not sure if that is the final solution. With your build speed control works but the set hysteresis (default: 5°C) seems to be ignored. This results in very frequent changes around trip points.
Did you just fix the uninitialized variable or apply the whole commit (https://github.com/raspberrypi/linux/commit/29d2bdf66191b6e50deef2110792c43c10cccfd9)?
E.g. lots of changes between states 0 and 1, with the fan sometimes stopping for just a fraction of a second: |
[Impact]
Fan toggles on/off if temp is around trip temp.
[Fix]
https://github.com/raspberrypi/linux/commit/d3668f4e7e2747f38d7f680df231f02dd33d3a13
[Test Case]
Observe fan behavior when temp crosses the trip temp (in both directions). Hysteresis should prevent rapid on/off toggling.
[Where Problems Could Occur]
Fan on Pi might misbehave (stuck on or off or toggling).
