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.

See the lm_sensors download page for further guidance:

The list above may be out of date;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.

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.

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.

Please read INSTALL before trying to compile and install these modules.
There is a lot of additional documentation in the doc/ subdirectory.

The developers of this package can be reached through a mailing-list
(see http://www.lm-sensors.org/wiki/AuthorsAndContributors). Do not hesitate
to mail us if you have questions, suggestions, problems, want to
contribute, or just want to report it works for you. But please try to
read the documentation and FAQ before you ask any questions!

The latest version of this package can always be found at:
http://www.lm-sensors.org/wiki/Download. Pre-release versions can be
retrieved through anonymous SVN; see doc/svn for details.

This package may be distributed according to the GNU General Public
License (GPL), as included in the file COPYING.

Note that libsensors falls under the GPL, not the LGPL.  In more human
language, that means it is FORBIDDEN to link any application to the
library, even to the shared version, if the application itself does not
fall under the GPL.
