| # Sensor Config |
| This program is only meant to control fans given thermal sensor readings. |
| |
| All sensors in phosphor-dbus-interfaces for OpenBMC use Sensor.Value as their |
| accessor. This provides read-only access to information. The goal of the |
| configuration is to specify how it can be read and if it's a fan, how the PID |
| output can be written. Initially there'll only be sysfs and passive dbus |
| access. If a writePath for a sensor is a dbus path, then the system will need |
| to verify which Control.Fan* interfaces is registered and send values to the |
| Target property of that interface. |
| |
| The min/max specified are to range a writePercent to the sensor. The current |
| FanController object outputs the new fan speed goal as a PWM percentage. Other |
| fan PID control objects may not, and they can leave the fields as 0 & 0. |
| |
| The only requirement for a sensor is that it isn't writeonly. Only fans are |
| expected to have a writePath set, and in this current version non-fan sensors |
| are assumed readonly. |
| |
| The sensor names are unique across all zones. |
| |
| # PID Config |
| |
| The PID configuration is a list of PIDs per zone. |
