It is -described in the 'Register Set Specification BMC Hermes based Systemboard' -from Fujitsu-Siemens. - -The Hermes 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 shut the system down. - -The chip provides three temperature values (CPU, motherboard and -auxiliary), three voltage values (+12V, +5V and battery) and three fans -(power supply, CPU and auxiliary). - -Temperatures are measured in degrees Celsius. 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 or 4) 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. - - -Detailed description --------------------- - -Below you'll find a single line description of all the bit values. With -this information, you're able to decode e. g. alarms, wdog, etc. To make -use of the watchdog, you'll need to set the watchdog time and enable the -watchdog.

This register is -read out every second, then the ripple prescaler (2, 4 or 8) is applied and -the result is stored in the 8 bit output register. Due to the limitation of -the counting register to 9 bits, it is impossible to measure a VERAX fan -properly (even with a prescaler of 8). At its maximum speed of 3500 RPM the -fan produces 1080 ripples per second which causes the counting register to -overflow twice, leading to only 186 RPM. - -* Measuring input voltages -in2 ("battery") reports the voltage of the onboard lithium battery and not -+3.3V from the power supply. - -* Undocumented features -Fujitsu-Siemens Computers has not documented all features of the chip so -far. Their software, System Guard, shows that there are a still some -features which cannot be controlled by this implementation. diff --git a/drivers/hwmon/Kconfig b/drivers/hwmon/Kconfig index ed7711d11ae8..9d881f708912 100644 --- a/drivers/hwmon/Kconfig +++ b/drivers/hwmon/Kconfig @@ -325,34 +325,6 @@ config SENSORS_F75375S This driver can also be built as a module.
