Up to 6 of those are +direct temperature sensor inputs, the others are special sources such as PECI, +PCH, and SMBUS. Depending on the chip type, 2 to 6 of the temperature sources +can be monitored and compared against minimum, maximum, and critical +temperatures. The driver reports up to 10 of the temperatures to the user. +There are 4 to 5 fan rotation speed sensors, 8 to 15 analog voltage sensors, +one VID, alarms with beep warnings (control unimplemented), and some automatic +fan regulation strategies (plus manual fan control mode). + +The temperature sensor sources on all chips are configurable. The configured +source for each of the temperature sensors is provided in tempX_label. + +Temperatures are measured in degrees Celsius and measurement resolution is +either 1 degC or 0.5 degC, depending on the temperature source and +configuration. An alarm is triggered when the temperature gets higher than +the high limit; it stays on until the temperature falls below the hysteresis +value. Alarms are only supported for temp1 to temp6, depending on the chip type. + +Fan rotation speeds are reported in RPM (rotations per minute). An alarm is +triggered if the rotation speed has dropped below a programmable limit. On +NCT6775F, fan readings can be divided by a programmable divider (1, 2, 4, 8, +16, 32, 64 or 128) to give the readings more range or accuracy; the other chips +do not have a fan speed divider. The driver sets the most suitable fan divisor +itself; specifically, it increases the divider value each time a fan speed +reading returns an invalid value, and it reduces it if the fan speed reading +is lower than optimal. Some fans might not be present because they share pins +with other functions. + +Voltage sensors (also known as IN sensors) report their values in millivolts. +An alarm is triggered if the voltage has crossed a programmable minimum +or maximum limit. + +The driver supports automatic fan control mode known as Thermal Cruise. +In this mode, the chip attempts to keep the measured temperature in a +predefined temperature range. If the temperature goes out of range, fan +is driven slower/faster to reach the predefined range again. + +The mode works for fan1-fan5. + +sysfs attributes +---------------- + +pwm[1-5] - this file stores PWM duty cycle or DC value (fan speed) in range: + 0 (lowest speed) to 255 (full) + +pwm[1-5]_enable - this file controls mode of fan/temperature control: + * 0 Fan control disabled (fans set to maximum speed) + * 1 Manual mode, write to pwm[0-5] any value 0-255 + * 2 "Thermal Cruise" mode + * 3 "Fan Speed Cruise" mode + * 4 "Smart Fan III" mode (NCT6775F only) + * 5 "Smart Fan IV" mode + +pwm[1-5]_mode - controls if output is PWM or DC level + * 0 DC output + * 1 PWM output + +Common fan control attributes +----------------------------- + +pwm[1-5]_temp_sel Temperature source.
