Description
|
||||
-----------
|
||||
|
||||
The Standard Microsystems Corporation (SMSC) EMC2103 chips
|
||||
contain up to 4 temperature sensors and a single fan controller.
|
||||
|
||||
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 1, the lowest
|
||||
representable value is 480 RPM.
|
||||
|
||||
This driver supports RPM based control, to use this a fan target
|
||||
should be written to fan1_target and pwm1_enable should be set to 3.
|
||||
|
||||
The 2103-2 and 2103-4 variants have a third temperature sensor, which can
|
||||
be connected to two anti-parallel diodes. These values can be read
|
||||
as temp3 and temp4. If only one diode is attached to this channel, temp4
|
||||
will show as "fault". The module parameter "apd=0" can be used to suppress
|
||||
this 4th channel when anti-parallel diodes are not fitted.
