* Better VDD internal computation, as described in the data sheet; * Fixed the config file to reflect the above change; * The library read the wrong file to get its gl518sm alarm data. git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@150 7894878c-1315-0410-8ee3-d5d059ff63e0

# Hardware sensors configuration file
|
|
|
|
# This configuration file will be used by all applications linked to
|
|
# libsensors.
|
|
|
|
# This config file consists of two parts: the heavily commented LM78
|
|
# example, and the real parts. Search for '####' if you want to skip
|
|
# to the real stuff.
|
|
|
|
# Hash marks introduce comments, which continue until the end of a line
|
|
#
|
|
# Identifiers consisting of only digits and letters can be used
|
|
# unquoted; other identifiers must be quoted. Escape characters within
|
|
# quotes operate like those in C.
|
|
|
|
# A 'chip' line specifies what the following 'label', 'compute', 'set' and
|
|
# (not yet implemented) 'valid' lines refer to. In this case, until the
|
|
# next 'chip' line, everything refers to all lm78, lm78-j and lm79
|
|
# chips. Other examples are *-isa-* for everything on the ISA bus, and
|
|
# lm78-j-i2c-*-4e for all lm78-j chips on address 0x4e of any I2C bus.
|
|
#
|
|
# If more chip statements match a specific chip, they are all considered.
|
|
# Later lines overrule earlier lines, so if you set the in0 label for
|
|
# lm78-* to "This", and later on the in0 label for lm78-isa-* to "That",
|
|
# "That" is used for LM78 chips on the ISA bus, and "This" for LM78
|
|
# chips on a non-ISA bus.

#chip "lm78-*" "lm78-j-*" "lm79-*"

|
|
# A label line describes what a certain feature stands for on your
|
|
# mainboard. Programs can retrieve these names and display them.
|
|
# If no label is specified for a certain feature, the default name
|
|
# (ie. 'fan1' for fan1) is used.
|
|
|
|
# If you specify a label for in1, this label is also used for in1_min and
|
|
# in1_max, unless they have their own labels declared. There are several
|
|
# of these logical groups.
|
|
|
|
# These are as advised in the LM78 and LM79 data sheets, and used on almost
|
|
# any mainboard we have seen.

|
|
# A compute line describes how to scale a certain feature. There are
|
|
# two expressions in it: the first describes how the /proc value must
|
|
# be translated to a user value, the second how a user value must be
|
|
# translated to a /proc value. '@' is the value to operate on. You may
|
|
# refer to other readable features (like '2 * vid').
|
|
|
|
# Like for the label statement, there are logical groups here. They are
|
|
# sometimes a bit different, though. For example, fan1_div is in the
|
|
# logical label group of fan1 (it gets the same label if none is declared
|
|
# for it), but it is not in the compute group of fan1 (as it uses a
|
|
# completely different system of values).

|

# If we refer from now on to 'i2c-0' in 'chip' lines, this will run-time

# be matched to this bus. So even if the PIIX4 is called 'i2c-5' at that
|
|
# moment, because five other adapters were detected first, 'i2c-0' in
|
|
# the config file would always only match this physical bus. In the above

|
# config file, this feature is not needed; but the next lines would
|
|
# only affect the LM75 chips on the PIIX4 adapter:

#chip "lm75-i2c-0-*"
