This is an announcement of lm_sensors version 2.1.0. Note that new versions
are released very often, usually at least once a week. By the time you read
this, a new version may already be available at http://www.netroedge.com/~lm78.
lm_sensors is a collection of Linux kernel modules for 2.0 and 2.1 (and the
upcoming 2.2) kernels. It provides access to the hardware monitoring devices
which are available on almost all newer (read: less than a year old)
mainboards. These sensors report the currently measured voltage levels,
temperatures and fan rotation speeds, as well as some less important things.
The modules currently support the LM78, LM78-J, LM79, LM80, W83781D and
GL518SM chips. These chips can be accessed both through the ISA bus and
through the System Management Bus, commonly called SMBus. More chips will
be supported in the near future.
SMBus is a protocol that runs over the I2C (pronounce: I square C) bus.
lm_sensors version 2 is built upon Simon Vogl's I2C kernel modules, which
means that it supports any bus type that is supported by that package.
This includes the VIA chipset southbridge, a chipset used on many non-Intel
mainboards. There is also a native (non-I2C) driver for the Intel PIIX4(E)
in the lm_sensors package.
Sensor readings are exported to user-space through the /proc and sysctl
interfaces. As these tend to be a bit hard for humans to read (though
they are ideal for programs), a sample program is included which pretty
prints all sensor data.
Because different mainboard can use the same sensor chip in different
ways, version 2 of lm_sensors implements a configuration file which can
be used to describe this. This file will be automatically read by all
applications which are linked to the included library. An example
program illustrates how this can be done.
If you have used version 1.x.y in the past, you will see that a lot has
changed since then. We still call the current 2.1.0 version beta, but
it seems at least as stable as the 1.x.y versions.
Below you can find the LSM entry. Please contact the developers (Frodo
Looijaard and Philip Edelbrock) through the developers mailing list
at lm78 _at_ stimpy.netroedge.com if you have questions, suggestions, problems
or patches. Or even if you just want to tell us it worked for you!
Happy new year,

Title: lm_sensors
Version: 2.1.0
Entered-date: 29DEC98
Description: Hardware health monitoring package for Linux. It consists of
kernel modules to access sensor chips and SMBus hardware,
of a library to allow applications to read this data more
easily, and of an example program to pretty print this data.
LM78, LM79, LM80, W83781D and GL518SM sensor chips are
supported, among others. PIIX4 and VIA chipset SMBus
implementations are supported, as well as many I2C busses.
Version 2 is a complete non-compatible modular rewrite of this
package, with full I2C and SMBus support.
Keywords: kernel module SMBus sensors LM78 health
