Should one understand that it IS a wanted behaviour ?

Isn't it the DSDT job (which is kernel-accessible, or isn't it ?) to
communicate trip_points to ACPI thermal zone ?

Isn't OSPM managing thermal zone ?

(http://acpi.sourceforge.net/documentation/thermal.html)




PS : Sorry for all these (maybe stupid) questions, but I think I
remember that changing trip_points had an effect on a (DSDT-bugged)
laptop I used to use, and I'd like to understand...

PPS : Sorry also for the english mistakes or approximations...
