[PATCH linux dev-4.19 00/12] PECI device driver introduction

[Jae Hyun Yoo]

Hi Henbin,

No, PECI hwmon can't be created by the udev->start_hwmon.sh.
To create PECI hwmon, you might need to use these two packages:
https://github.com/openbmc/entity-manager
https://github.com/openbmc/dbus-sensors

PECI hwmon needs runtime creation because it needs to collect CPU
package information such as core numbers and installed DIMMs.

If you want to create PECI hwmon manually, you can try:
echo 'peci-client 0x30' > /sys/bus/peci/devices/peci-0/new_device
echo 'peci-client 0x30' > /sys/bus/peci/devices/peci-0/delete_device

Make sure that the host should be powered on when you create it.

Cheers,
Jae
