However, most -standard PMBus commands are not supported. Specifically, all hardware monitoring -and status reporting commands are non-standard. For this reason, a standard -PMBus driver can not be used. - - -Usage Notes ------------ - -This driver does not probe for Lineage CPL devices, since there is no register -which can be safely used to identify the chip. You will have to instantiate -the devices explicitly. - -Example: the following will load the driver for a Lineage PEM at address 0x40 -on I2C bus #1: -$ modprobe lineage-pem -$ echo lineage-pem 0x40 > /sys/bus/i2c/devices/i2c-1/new_device - -All Lineage CPL power entry modules have a built-in I2C bus master selector -(PCA9541). To ensure device access, this driver should only be used as client -driver to the pca9541 I2C master selector driver. - - -Sysfs entries -------------- - -All Lineage CPL devices report output voltage and device temperature as well as -alarms for output voltage, temperature, input voltage, input current, input power, -and fan status. - -Input voltage, input current, input power, and fan speed measurement is only -supported on newer devices. The driver detects if those attributes are supported, -and only creates respective sysfs entries if they are. - -in1_input Output voltage (mV) -in1_min_alarm Output undervoltage alarm -in1_max_alarm Output overvoltage alarm -in1_crit Output voltage critical alarm - -in2_input Input voltage (mV, optional) -in2_alarm Input voltage alarm - -curr1_input Input current (mA, optional) -curr1_alarm Input overcurrent alarm - -power1_input Input power (uW, optional) -power1_alarm Input power alarm - -fan1_input Fan 1 speed (rpm, optional) -fan2_input Fan 2 speed (rpm, optional) -fan3_input Fan 3 speed (rpm, optional) - -temp1_input -temp1_max -temp1_crit -temp1_alarm -temp1_crit_alarm -temp1_fault |
