New Thermal Trip Types for Linux Kernel

Explore new thermal trip types in this Linux Plumbers Conference talk. Learn about the limitations of current 'hot', 'passive', 'active', and 'critical' trip points, and discover how introducing writable 'custom' trip points can benefit userspace applications. Understand how these custom trip points allow for programmable interrupt triggers, reducing the need for constant temperature polling and minimizing system wake-ups. Gain insights into separating kernel-level actions for silicon protection from userspace-managed thermal behaviors at lower temperatures, ultimately improving overall system thermal management.
