NVS: Add a temp sensor ID and an ACPI Method to set it
This will allow various teams to select which thermal sensor will control the thermal zones. Also add a method to notify the thermalzones of a change so these threshold/sensor methods take effect. Needs a modified BIOS that uses the NVS TMPS value in the thermalzone to read a different sensor. Then, use a kernel driver that contains the following: /* Adjust temperature sensor id to 2 */ union acpi_object param; struct acpi_object_list input; param.type = ACPI_TYPE_INTEGER param.integer.value = 2 input.count = 1; input.pointer = &param; acpi_evaluate_object(NULL, "\\TMPU", &input, NULL); And ensure that the temperature sensor that is being monitored switches to ID 2.
