.SH NAME
|
|
sensors-find-driver \- find driver corresponding to a sensor chip
|
|
.SH SYNOPSIS
|
|
.B sensors-find-driver
|
|
.I chip-name
|
|
|
|
.SH DESCRIPTION
|
|
.B sensors-find-driver
|
|
Chip name is a string in the format
|
|
.I <chip>-<bus>-<address>
|
|
as reported by the
|
|
.I sensors
|
|
program. For example the chip name can be
|
|
.I coretemp-isa-0000
|
|
or
|
|
.I acpitz-virtual-0
|
|
.P
|
|
If the
|
|
.I sensors
|
|
program does not report useful values for certain hardware
|
|
monitoring inputs, the problem in most cases is not in lm_sensors. lm_sensors
|
|
only reads values exported by the Linux kernel. Finding the driver responsible
|
|
for exporting the particular hardware monitoring chip may help to diagnose
|
|
the problem further. It is possible that there is a bug in the driver, however
|
|
it is even more likely that the input is simply not used on your board.
|
|
|
|
Nonetheless, identifying the driver may help you identify the piece of hardware
|
|
that reports the bogus value.
|
|
|
|
This script finds the driver and kernel module responsible for exporting
|
|
a hardware monitoring chip in sysfs. It should be given the chip name as
|
|
reported by the
|
|
.I sensors
|
|
|
|
program as argument. For example:
|
|
|
|
.br
|
|
$ sensors
|
|
.br
|
|
thinkpad-isa-0000
|
|
.br

|
Adapter: ISA adapter

$ sensors-find-driver thinkpad-isa-0000

Driver: thinkpad_hwmon
