- 0. Introduction
- The generic cpu cooling(freq clipping) provides registration/unregistration APIs
- to the caller. The binding of the cooling devices to the trip point is left for
- the user. The registration APIs returns the cooling device pointer.
- 1. cpu cooling APIs
- 1.1 cpufreq registration/unregistration APIs
- 1.1.1 struct thermal_cooling_device *cpufreq_cooling_register(
- struct cpumask *clip_cpus)
- This interface function registers the cpufreq cooling device with the name
- "thermal-cpufreq-%x". This api can support multiple instances of cpufreq
- cooling devices.
- clip_cpus: cpumask of cpus where the frequency constraints will happen.
- 1.1.2 void cpufreq_cooling_unregister(struct thermal_cooling_device *cdev)
- This interface function unregisters the "thermal-cpufreq-%x" cooling device.
- cdev: Cooling device pointer which has to be unregistered.
