The -hardware monitoring block is not supported by this driver, use the -smsc47m192 driver for that. - -No documentation is available for the 47M997, but it has the same device -ID as the 47M15x and 47M192 chips and seems to be compatible. - -Fan rotation speeds are reported in RPM (rotations per minute). An alarm is -triggered if the rotation speed has dropped below a programmable limit. Fan -readings can be divided by a programmable divider (1, 2, 4 or 8) to give -the readings more range or accuracy. Not all RPM values can accurately be -represented, so some rounding is done. With a divider of 2, the lowest -representable value is around 2600 RPM. - -PWM values are from 0 to 255. - -If an alarm triggers, it will remain triggered until the hardware register -is read at least once. This means that the cause for the alarm may -already have disappeared! Note that in the current implementation, all -hardware registers are read whenever any data is read (unless it is less -than 1.5 seconds since the last update). This means that you can easily -miss once-only alarms. - ------------------------------------------------------------------- - -The lm_sensors project gratefully acknowledges the support of -Intel in the development of this driver. |
