@ -2,17 +2,12 @@ Naming and data format standards for sysfs files
------------------------------------------------
The libsensors library offers an interface to the raw sensors data
through the sysfs interface. See libsensors documentation and source for
further information. As of writing this document, libsensors
(from lm_sensors 2.8.3) is heavily chip-dependent. Adding or updating
support for any given chip requires modifying the library's code.
This is because libsensors was written for the procfs interface
older kernel modules were using, which wasn't standardized enough.
Recent versions of libsensors (from lm_sensors 2.8.2 and later) have
support for the sysfs interface, though.
The new sysfs interface was designed to be as chip-independent as
possible.
through the sysfs interface. Since lm-sensors 3.0.0, libsensors is
completely chip-independent. It assumes that all the kernel drivers
implement the standard sysfs interface described in this document.
This makes adding or updating support for any given chip very easy, as
libsensors, and applications using it, do not need to be modified.
This is a major improvement compared to lm-sensors 2.
Note that motherboards vary widely in the connections to sensor chips.
There is no standard that ensures, for example, that the second

will have to implement conversion, labeling and hiding of inputs. For
this reason, it is still not recommended to bypass the library.
If you are developing a userspace application please send us feedback on
this standard.
Note that this standard isn't completely established yet, so it is subject
to changes. If you are writing a new hardware monitoring driver those
features can't seem to fit in this interface, please contact us with your
extension proposal. Keep in mind that backward compatibility must be
preserved.
Each chip gets its own directory in the sysfs /sys/devices tree. To
find all sensor chips, it is easier to follow the device symlinks from
/sys/class/hwmon/hwmon*.
Up to lm-sensors 3.0.0, libsensors looks for hardware monitoring attributes
in the "physical" device directory. Since lm-sensors 3.0.1, attributes found
in the hwmon "class" device directory are also supported. Complex drivers
(e.g. drivers for multifunction chips) may want to use this possibility to
avoid namespace pollution. The only drawback will be that older versions of
libsensors won't support the driver in question.
All sysfs values are fixed point numbers.
There is only one value per file, unlike the older /proc specification.

comment "Texas Instruments PCILynx requires I2C"
You should only build either ohci1394 or the new firewire-ohci driver,
but not both. If you nevertheless want to install both, you should
configure them only as modules and blacklist the driver(s) which you
don't want to have auto-loaded. Add either
blacklist firewire-ohci
or
blacklist ohci1394
blacklist video1394
blacklist dv1394
to /etc/modprobe.conf or /etc/modprobe.d/* and update modprobe.conf
depending on your distribution. The latter two modules should be
blacklisted together with ohci1394 because they depend on ohci1394.
If you have an old modprobe which doesn't implement the blacklist
directive, use "install modulename /bin/true" for the modules to be
blacklisted.
