Linux s Yogafan Driver Prepares Support For Newer Lenovo Laptops
Curated from Phoronix
If you manage a fleet of Lenovo workstations, the Yogafan HWMON driver is quietly becoming critical for thermal governance. While the initial Linux 7.1 implementation covered a limited subset of Yoga and Legion models, recent kernel updates have significantly expanded device compatibility. This matters for SREs because relying on generic ACPI thermal zones often leads to aggressive, unnecessary fan noise or insufficient cooling under sustained load. The Yogafan driver provides granular HWMON access, allowing you to script precise fan curves that align with your specific SLA requirements for noise and temperature. For anyone running custom fan control policies or integrating thermal telemetry into monitoring stacks, this upstream progress reduces the need for fragile, vendor-specific userspace hacks. Check your specific laptop model against the latest supported list before deploying custom thermal management scripts.
Introduced back in Linux 7.1 was the Yogafan HWMON driver for supporting fan speed monitoring across various Lenovo Yoga, Legion, Flex, Slim, and IdeaPad laptops. An initial set of Lenovo laptops was initially supported by this driver while succeeding kernel versions have continued building out the support...
