Also available through debugfs are 23the serial number, firmware version and power-on count. Attaching a fan to it is 24optional and allows it to be controlled using temperature curves directly from the 25pump. If it's not connected, the fan-related sensors will report zeroes. 26 27The pump can be configured either through software or via its physical 28interface. Configuring the pump through this driver is not implemented, as it 29seems to require sending it a complete configuration. That includes addressable 30RGB LEDs, for which there is no standard sysfs interface. Thus, that task is 31better suited for userspace tools. 32 33The Octo exposes four temperature sensors and eight PWM controllable fans, along 34with their speed (in RPM), power, voltage and current. 35 36The Farbwerk and Farbwerk 360 expose four temperature sensors. Depending on the device, 37not all sysfs and debugfs entries will be available. 38 39Usage notes 40----------- 41 42The devices communicate via HID reports. The driver is loaded automatically by 43the kernel and supports hotswapping. 44 45Sysfs entries 46------------- 47 48================ ============================================= 49temp[1-4]_input Temperature sensors (in millidegrees Celsius) 50fan[1-2]_input Pump/fan speed (in RPM) 51power[1-2]_input Pump/fan power (in micro Watts) 52in[0-2]_input Pump/fan voltage (in milli Volts) 53curr[1-2]_input Pump/fan current (in milli Amperes) 54================ ============================================= 55 56Debugfs entries 57--------------- 58 59================ ================================================= 60serial_number Serial number of the device 61firmware_version Version of installed firmware 62power_cycles Count of how many times the device was powered on 63================ =================================================
