    ACPI: thermal: create "thermal.psv=" to override passive trip points · a70cdc52
    Len Brown 提交于
    "thermal.psv=-1" disables passive trip points
    for all ACPI thermal zones.
    
    "thermal.psv=C", where 'C' is degrees Celsius,
    overrides all existing passive trip points
    for all ACPI thermal zones.
    
    thermal.psv is checked at module load time,
    and in response to trip-point change events.
    
    Note that if the system does not deliver thermal zone
    temperature change events near the new trip-point,
    then it will not be noticed.  To force your custom
    trip point to be noticed, you may need to enable polling:
    eg. thermal.tzp=3000 invokes polling every 5 minutes.
    
    Note that once passive thermal throttling is invoked,
    it has its own internal Thermal Sampling Period (_TSP),
    that is unrelated to _TZP.
    
    WARNING: disabling or raising a thermal trip point
    may result in increased running temperature and
    shorter hardware lifetime on some systems.
