why is 0072 is needed? i thought we have disabled thermal zone on this branch? |
|
0076 is a new feature, why do we need it on 201911 branch? |
In order to use kernel thermal control algorithm, thermalctld will enable thermal zone when it starts. |
Hi Guohan, this new sensor support is required by the MSN4700 A1 system, we also planned to support it in 201911. |
added on top of Junchao's feedback: it is NOT that the thermal zone is altogether disabled, what was disabled is the critical trip points to avoid the shutting down of zones by the thermal zone mechanism , but beside that the mechanism is still there and provides indications, such as warnings of changing temperatures etc. this patch is a common fix for the thermal zone mechanism, so it still valuable to backport it. |
