For cpuidle_cooling_runtime() returning 0, no idle-injection is applied. For an idle injection percentage of 0, this makes sense. But this happends for the idle injection percentage of 100 too, which is wrong. The documented calculation: ((idle_cycle * 100) / state) - idle_cycle results 0 for state being 100. For "state" from 0 to 99, the thermal driver throttles accordingly and keeps the CPUs cool. When switching to 100, it stops cooling, we see a jump up in temperature and the CPU heats up until it shuts down. Work around this problem by keeping the "state" at 99 for calculations, never reaching 100. The user interface still reaches 100, but there is no formal connection to actual data and the UI. It's just a unified range that can be implemented in various ways.
