Description

-----------
|
||||
|
||||
i2c-viapro is a true SMBus host driver for motherboards with one of the
|
||||
supported VIA southbridges.
|
||||
|
||||
Your /proc/pci or lspci -n listing must show either of these :
|
||||
|
||||
device 1106:3050 (vt82c596 function 3)
|
||||
device 1106:3057 (vt82c686 function 4)
|
||||
|
||||
If neither of these show up, you should look in the BIOS for settings like
|
||||
enable ACPI / SMBus or even USB.
|
||||
|
||||
To install this driver, simply do
|
||||
# modprobe i2c-viapro

Description
|
||||
-----------
|
||||
|
||||
This driver supports the Genesys Logic GL520SM chip.
|
||||
|
||||
The GL520SM implements one temperature sensor, two FAN rotation speed
|
||||
sensors, four voltage sensors and the cpu VID lines. In addition, one input
|
||||
can be configured as either a temperature or voltage sensor.
|
||||
The sensor can report alarms through the computer speakers.
|
||||
|
||||
Temperatures are measured in degrees Celcius. An alarm goes off while the
|
||||
temperature is above the over temperature limit, and has not yet dropped
|
||||
below the hysteris limit. The alarm always reflects the current situation.
|
||||
Measurements are guaranteed between 0 degrees and +110 degrees, with
|
||||
a resolution of +-3 degrees.
|
||||
|
||||
FAN rotation speeds are reported in RPM (rotations per minute). An alarm is
|
||||
triggered if the rotation speed has dropped below a programmable limit.
|
||||
In case when you have selected to turn Fan1 off, no Fan1 alarm is triggered
|
||||
if measured temperature is below 'over temperature' limit.
|
||||
|
||||
FAN readings can be divided by a programmable divider (1, 2, 4 or 8) to give
|
||||
the readings more range or accuracy. This is important because some FANs
|
||||
report only one 'tick' each rotation, while others report two.
|
||||
Not all RPM values can accurately be represented, so some rounding is done.
|
||||
With a divider of 2, the lowest representable value is around 1900 RPM.
|
||||
|
||||
Voltage sensors (also known as VIN sensors) report their values in volts. An
|
||||
alarm is triggered if the voltage has crossed a programmable minimum or
|
||||
maximum limit. Note that minimum in this case always means 'closest to
|
||||
zero'; this is important for negative voltage measurements. The VDD input
|
||||
measures voltages between 0.000 and 5.865 volt, with a resolution of 0.023
|
||||
volt. The other inputs measure voltages between 0.000 and 4.845 volt, with a
|
||||
resolution of 0.019 volt.
|
||||
|
||||
When an alarm goes off, you can be warned by a beeping signal through
|
||||
your computer speaker. It is possible to enable all beeping globally,
|
||||
or only the beeping for some alarms.
|
||||
|
||||
If an alarm triggers, it will remain triggered until the hardware register
|
||||
is read at least once (except for temperature alarms). 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 GL520SM only updates its values each 1.5 seconds; reading it more often
|
||||
will do no harm, but will return 'old' values.
