Improvisation and Demonstration of Linux Thermal Framework for Multiple Temperature Sensors

Explore the Linux Thermal Framework for managing multiple temperature sensors in this 34-minute conference talk presented by Adithya K V and Tauseef Nomani from Samsung Semiconductor India Research. Delve into thermal management units, temperature controllers, and the Linux Thermal Framework's structures and functions. Learn about cooling device structures, thermal zone device registration, and sensor registration processes. Examine conventional TMU drivers, temperature retrieval, emulation setting, and policies. Discover trick points, modes, and types in thermal management. Address the challenges of complex SOCs and limitations in conventional TMU drivers, and gain insights into potential solutions for improved thermal management in Linux systems.
