This is the completely rewritten version of lm_sensors, a collection of
|
|
modules for general SMBus access and hardware monitoring. There are quite
|
|
a few changes compared with 1.x.y versions; read doc/version-2 for the
|
|
most interesting ones.
|
|
|
|
SMBus, also known as System Management Bus, is a protocol for communicating
|
|
through a I2C ('I squared C') bus. Many modern mainboards have a System
|
|
Management Bus. There are a lot of devices which can be connected to a
|
|
SMBus; the most notable are modern memory chips with EEPROM memories and
|
|
chips for hardware monitoring.
|
|
|
|
Most modern mainboards incorporate some form of hardware monitoring chips.
|
|
These chips read things like chip temperatures, fan rotation speeds and
|
|
voltage levels. There are quite a few different chips which can be used
|
|
by mainboard builders for approximately the same results.
|
|
|
|
Hardware monitoring chips are often connected to the SMBus, but often they
|
|
can also be connected to the ISA bus. The modules in this package usually
|
|
support both ways of accessing them.
|
|
|
|
Because the SMBus is just a special case of the generalized I2C bus, we
|
|
can simulate the SMBus protocol on plain I2C busses. These busses are
|
|
sometimes used in other parts of your computer. If a supported chips is
|
|
attached to one of these additional busses, they can be used too.
|
|
|
|
Please read INSTALL before trying to compile and install these modules.
|
|
There is a lot of additional documentation in the doc/ subdirectory.
|
|
Amnong these is a list of supported busses and chips. Regrettably, there
|
|
are too many mainboards to keep a list of busses and chips used on them.
|
|
We will provide a user-space utility which probes for the presence of
|
|
chips and busses in one of the next releases.
