+ help
+ Select this option to enable thermal pressure accounting in the
+ scheduler. Thermal pressure is the value conveyed to the scheduler
+ that reflects the reduction in CPU compute capacity resulted from
+ thermal throttling. Thermal throttling occurs when the performance of
+ a CPU is capped due to high operating temperatures.
+
+ If selected, the scheduler will be able to balance tasks accordingly,
+ i.e. put less load on throttled CPUs than on non/less throttled ones.
+
+ This requires the architecture to implement
+ arch_set_thermal_pressure() and arch_get_thermal_pressure().
