Hi folks, This system: https://dflund.se/~triad/krad/dlink-dns-313/ Has: - 1 GPIO fan using drivers/hwmon/gpio-fan.c - 1 temperature sensor using drivers/hwmon/lm75.c So it is the simplest form of chassis cooling. Is it possible to use drivers/thermal to set up a policy for controlling the HWMON fan directly by reading the HWMON sensor input periodically? If not: should it be? It seems natural to me. I guess this stuff is normally "policy in userspace" but we already have thermal policies in the kernel, so...
