🌈 estimate_pid_constants(9) 🌈

okay bestie, welcome to the Kernel API Manual ✨ this page is literally all about estimate_pid_constants, and it's giving very specific thermal-zone energy. Let's get into it 💅

🌸 NAME 🌸

estimate_pid_constants — Estimate the constants for the PID controller 🎀

✨ SYNOPSIS ✨

void estimate_pid_constants (struct thermal_zone_device *tz , u32 sustainable_power , const struct thermal_trip *trip_switch_on , int control_temp );

🫶 ARGUMENTS 🫶

• tz — the thermal zone for which to estimate the constants 🌡️
• sustainable_power — the sustainable power for the thermal zone ⚡
• trip_switch_on — the trip point for the switch on temperature 🔥
• control_temp — the target temperature for the power allocator governor 🎯

💖 DESCRIPTION 💖

This function is used to update the estimation of the PID controller constants in struct thermal_zone_parameters ✨ like, that's the whole vibe. It's updating the estimation, periodt. No cap, that's what it does 🫶
