Dasharo ACPI Fan Control Linux Driver Posted For Adjusting Fan Curves

The 3mdeb consulting firm that has ported their Coreboot-based open-source firmware stack to the likes of an AMD Ryzen AM5 motherboard from MSI and a Gigabyte EPYC server motherboard, among others, has posted a new Linux kernel driver for supporting fan controls with Dasharo firmware. The proposed dasharo-acpi driver introduces the ability from Linux to control the fan PWM and configuring the fan curves for systems running the Dasharo firmware. Well, that's the plan at least with the initial patches only supporting the monitoring of the fans without adding in the actual write/control support. This driver was tested on a NovaCustom V560TU laptop with an upcoming Dasharo firmware build that adds the new fan control support from the firmware side. Those interested can find the Dasharo ACPI fan driver out for review on the kernel mailing list.
