I have made a driver for ACPI EC compatible laptops. The device configuration is available by reading and writing into ACPI EC memory. The driver depends on acpi_ec kernel module, which exposes ACPI EC memory as /dev/ec device. If this module is not available in the kernel, then it can be installed as a separate package from https://github.com/saidsay-so/acpi_ec
The code of the this liquidctl driver was based on ISW projects: https://github.com/YoyPa/isw https://github.com/FaridZelli/ISW-Modern
Both projects are unmaintained now. So I also made a simplified fork for learning and debug purposes - https://github.com/kyokenn/isw-stealth
ISW project was originally made for MSI laptops, but there are also other projects, which uses the same interface: https://github.com/hirschmann/nbfc/tree/master https://github.com/nbfc-linux/nbfc-linux
I have added support for my laptop with this driver, but more laptops could be added later.
The driver allows CPU/GPU temperature monitoring, CPU/GPU fan speed monitoring, fan speed configuration, led mode configuration.
