Description
Even though the thermal framework has evolved significantly over the past five years, several limitations and open issues remain. The step_wise governor still struggles to strike a better trade-off between performance and avoiding interrupt storms, and thermal-zone mitigations tend to stop too early during system suspend. Moreover, newer hardware provides fine-grained temperature telemetry that the framework does not yet leverage.
This talk will illustrate these limitations with simple diagrams and propose a direction to improve the thermal framework.
