OVERVIEW OF THE LM-SENSORS PACKAGE
==================================
FOR QUICK INSTALLATION INSTRUCTIONS SEE THE 'QUICKSTART' FILE.
FOR FULL INSTALLATION INSTRUCTIONS SEE THE 'INSTALL' FILE.
FOR THE FAQ SEE THE 'doc/FAQ' or 'doc/lm_sensors-FAQ.html' FILES.
The lm-sensors package, version 3, provides user-space support for the
hardware monitoring drivers in Linux 2.6.5 and later. For older kernel
versions, you have to use lm-sensors version 2.
=============================================================================
The directories within this package:
OVERVIEW OF THE LM_SENSORS PACKAGE AND SUMMARY OF SUPPORTED DEVICES
!!! This package is ONLY for 2.6 and 2.4 kernels (2.4.10 or later). !!!
!!! For 2.4 kernels, this package requires i2c-2.9.0 or later. !!!
FOR 2.6 KERNELS, use only the userspace tools in this package!
Build and install them with 'make user' and 'make user_install'.
The kernel modules in this package will NOT compile for 2.6;
use the drivers already in the 2.6 kernel. Check the QUICKSTART
file for brief installation instructions please.
=============================================================================
This is the completely rewritten version 2 of lm_sensors, a collection of
modules for general SMBus[1] access and hardware monitoring.
Version 1 is now officially unsupported.
WARNING! The drivers in this package will work on reasonably recent 2.4
kernels only (2.4.10 and later).
Use lm_sensors-2.4.5 for 2.0 kernels.
Use lm_sensors-2.7.0 for 2.2, and early 2.4 (up to 2.4.9) kernels.
Use the drivers already in the kernel for 2.6 kernels; if you need
additional drivers in 2.6 please port and submit them to us.
HOWEVER, the userspace tools in this package will work for
both 2.4 and 2.6 kernels.
The I2C[2] package in existing 2.4 kernels is NOT sufficient
for compilation of this package. You need i2c-2.9.0 or later.

Documentation.
* etc
A sample configuration file for libsensors, and a script to convert
lm-sensors version 2 configuration files to work with version 3.
* lib
The user-space sensors support library code (libsensors).
* prog
Several supporting programs. The most important ones are:
- sensors-detect: A program for detecting installed hardware and
recommending specific modules to load.
- sensors: A console tool to report sensor readings and set new
sensor limits.
- sensord: A daemon to watch sensor values and log problems. It
includes RRD support.

The list above may be out of date;
see our Devices page at http://www.lm-sensors.org/wiki/Devices
for the latest information on supported devices.
You may also refer to doc/chips/SUMMARY for details on what each chip
can monitor.
We always appreciate testers. If you own a specific monitoring chip we do
not yet (properly) support, and are willing to help us out, please contact
us. Even if you have no programming knowledge, you could help us by running
new modules and reporting on the results and output. If you want to offer
more substantial help, this is very welcome too, of course.
Don't ask us whether we support a particular mainboard; we do not know.
We *do* know what hardware we support, but usually, it is easier to
install everything and run sensors-detect. It will tell you what hardware
you have (and incidentally, what corresponding drivers are needed).
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.
HARDWARE SUPPORT
----------------
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 often have an SMBus or I2C interface. Some are
connected to ISA bus instead. Some of them can do both, in which case we
either support both access methods (old drivers) or only support ISA
access (new drivers) as it is faster.
Laptops, on the other hand, rarely expose any hardware monitoring
chip. They often have some BIOS and/or ACPI magic to get the CPU
temperature value, but that's about it. For such laptops, the lm-sensors
package is of no use (sensors-detect will not find anything), and you have
to use acpi instead.
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 chip is attached to
one of these additional busses, they can be used too.
This package doesn't contain chip-specific knowledge. It will support all
the hardware monitoring chips your kernel has drivers for. In other words,
if you find out that you have unsupported hardware (e.g. sensors-detect
told you so) then it means that you need a more recent kernel, or you
even need to wait for a new kernel driver to be written. Updating the
lm-sensors package itself will not help.
Please read INSTALL before trying to compile and install these modules.
There is a lot of additional documentation in the doc/ subdirectory.
