1 Kernel driver ibm-cffps 2 ======================= 3 4 Supported chips: 5 6 * IBM Common Form Factor power supply 7 8 Author: Eddie James <eajames@us.ibm.com> 9 10 Description 11 ----------- 12 13 This driver supports IBM Common Form Factor (CFF) power supplies. This driver 14 is a client to the core PMBus driver. 15 16 Usage Notes 17 ----------- 18 19 This driver does not auto-detect devices. You will have to instantiate the 20 devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for 21 details. 22 23 Sysfs entries 24 ------------- 25 26 The following attributes are supported: 27 28 ======================= ====================================================== 29 curr1_alarm Output current over-current alarm. 30 curr1_input Measured output current in mA. 31 curr1_label "iout1" 32 33 fan1_alarm Fan 1 warning. 34 fan1_fault Fan 1 fault. 35 fan1_input Fan 1 speed in RPM. 36 fan2_alarm Fan 2 warning. 37 fan2_fault Fan 2 fault. 38 fan2_input Fan 2 speed in RPM. 39 40 in1_alarm Input voltage under-voltage alarm. 41 in1_input Measured input voltage in mV. 42 in1_label "vin" 43 in2_alarm Output voltage over-voltage alarm. 44 in2_input Measured output voltage in mV. 45 in2_label "vout1" 46 47 power1_alarm Input fault or alarm. 48 power1_input Measured input power in uW. 49 power1_label "pin" 50 51 temp1_alarm PSU inlet ambient temperature over-temperature alarm. 52 temp1_input Measured PSU inlet ambient temp in millidegrees C. 53 temp2_alarm Secondary rectifier temp over-temperature alarm. 54 temp2_input Measured secondary rectifier temp in millidegrees C. 55 temp3_alarm ORing FET temperature over-temperature alarm. 56 temp3_input Measured ORing FET temperature in millidegrees C. 57 ======================= ======================================================
