Hello guys, For a patch to this nouveau bug [1] I'm trying to implement the sysfs interface for two properties (linear_min and linear_max) nouveau uses internally to decide when to raise the fan speed. The initial idea was to have them as custom sysfs attributes, but I was advised to try to fit them into the hwmon sysfs interface. And this is when I hit a little roadblock. If my understanding is correct (and I'm not ashamed to admit it probably isn't) trip points are used to tie together a specific fan speed to a specific temperature. Unfortunately nouveau does not quite work that way: those two properties above mark the temperature the driver uses to decide when to start and stop the *scaling* of the fan speed (from a specific minimum value all the way to 100%). Now, could I strech the trip point definition above to mean that a trip point specify a *minimum* value for the fan speed at a specific temperature, and that the driver can decide to use an higher speed as needed when the temperature goes above the one specified in the trip point without fear of breaking some convention/userspace tool that expect a constant fan speed? Is this an acceptable/correct usage for the interface?
