Hi,

We would like to create CPU temperature sensor.
We could see the hwmon file in the /sys/class/hwmon/
But we found the content of uevent file was empty.
That meant the sensor wasn't created through udev->start_hwmon.sh
Can you give some suggestion?

root at tiogapass:/sys/class/hwmon/hwmon4# cat name
peci_cputemp.cpu0
root at tiogapass:/sys/class/hwmon/hwmon4# cat uevent
root at tiogapass:/sys/class/hwmon/hwmon4#
root at tiogapass:/sys/class/hwmon/hwmon4#
