Description
|
|
-----------
|
|
|
|
This driver implements support for the Fujitsu Siemens Poseidon chip.
|
|
It is descibed in the 'Register Set Specification BMC Poseidon based
|
|
Systemboard' from Fujitsu Siemens.
|
|
|
|
The poseidon chip implements a hardware based system management,
|
|
e.g. for controlling fan speed and core voltage.
|
|
There is also a watchdog counter on the chip which can trigger
|
|
an alarm and even shutdown the system.
|
|
|
|
The chip provides three temperature values (cpu, motherboard and auxiliary),
|
|
three current values (12 volt, 5 volt and battery) and
|
|
three fans (power supply, cpu and auxiliary).
|
|
|
|
Temperatures are measured in degrees Celcius. The resolution is 1 degree.
|
|
|
|
FAN rotation speeds are reported in RPM (rotations per minute).
|
|
The value can be divided by a programmable divider (1, 2, 4 or 8) which
|
|
is stored on the chip.
|
|
|
|
Voltage sensors (also known as IN sensors) report their values in volts.
|
|
|
|
All values are reported as final values from the driver.
|
|
There is no need for further calculations.
