| 34 | Description |
|---|
| 35 | ----------- |
|---|
| 36 | |
|---|
| 37 | This driver implements support for the Fujitsu Siemens Poseidon chip. |
|---|
| 38 | It is descibed in the 'Register Set Specification BMC Poseidon based |
|---|
| 39 | Systemboard' from Fujitsu Siemens. |
|---|
| 40 | |
|---|
| 41 | The poseidon chip implements a hardware based system management, |
|---|
| 42 | e.g. for controlling fan speed and core voltage. |
|---|
| 43 | There is also a watchdog counter on the chip which can trigger |
|---|
| 44 | an alarm and even shutdown the system. |
|---|
| 45 | |
|---|
| 46 | The chip provides three temperature values (cpu, motherboard and auxiliary), |
|---|
| 47 | three current values (12 volt, 5 volt and battery) and |
|---|
| 48 | three fans (power supply, cpu and auxiliary). |
|---|
| 49 | |
|---|
| 50 | Temperatures are measured in degrees Celsius. The resolution is 1 degree. |
|---|
| 51 | |
|---|
| 52 | Fan rotation speeds are reported in RPM (rotations per minute). |
|---|
| 53 | The value can be divided by a programmable divider (1, 2, 4 or 8) which |
|---|
| 54 | is stored on the chip. |
|---|
| 55 | |
|---|
| 56 | Voltage sensors (also known as IN sensors) report their values in volts. |
|---|
| 57 | |
|---|
| 58 | All values are reported as final values from the driver. |
|---|
| 59 | There is no need for further calculations. |
