Getting Output for a Specific Device
Then, to get output for a specific device pass its name to the sensors command. For example, for
the Ethernet controller named xilinx_efct-pci-0100:
$ sensors xilinx_efct-pci-0100
xilinx_efct-pci-0100

Reading Sensor Values from the Filesystem
Sensors for Linux devices output their values into the /sys/class/hwmon hierarchy, in a
directory named /sys/class/hwmon/hwmon<n>/device.
To determine which of the hwmon<n>/device directories contain sensor data from the X3522
card, search for a driver file within the directory that is a soft link to the xilinx_efct driver:
$ for dir in /sys/class/hwmon/*/device
> do
> readlink $dir/driver | grep -Eq '/xilinx_efct$' && echo $dir
> done
/sys/class/hwmon/hwmon1/device
/sys/class/hwmon/hwmon2/device
/sys/class/hwmon/hwmon3/device
/sys/class/hwmon/hwmon4/device
So in the above example, the four directories /sys/class/hwmon/hwmon1/device to /sys/
class/hwmon/hwmon4/device (inclusive) contain sensor data from adapters using the
xilinx_efct driver.
Within these directories, each sensor has the following files:
