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_update_thermal_pressure() and arch_scale_thermal_pressure().
