Hi Felixzhang,
Yes, you can using op-power-control on X86 motherboard for sure.
Example about using op-power-control:
systemctl list-dependencies
obmc-host-start@0.target
obmc-host-start@0.target (Power ON)
-> mapper-wait@-org-openbmc-control-chassis0.service
-> phosphor-reset-host-reboot-attempts@0.service
-> obmc-host-startmin@0.target
-> mapper-wait@-org-openbmc-control-chassis0.service
-> obmc-enable-host-watchdog@0.service
-> phosphor-watchdog@poweron.service
-> obmc-chassis-poweron@0.target
-> op-power-start@0.service
-> mapper-wait@-xyz-openbmc_project-state-chassis0.service
-> phosphor-fan-control-init@0.service
-> phosphor-fan-monitor-init@0.service
-> phosphor-fan-presence-tach@0.service
BTW, here is the list about the sequence of
obmc-host-start@0.target for you refer it.
When you presss Power ON button from WebUI the state RequestedHostTransition change to ON, what happens behind that is done by systemd
units, roughly described as below:
1.
Host state manager starts
obmc-host-start@0.target
2.
The above target requires
obmc-host-startmin@0.target
3.
The above target requires
obmc-chassis-poweron@0.target and start_host@0.service
4.
obmc-chassis-poweron@0.target
requires op-power-start@0.service and op-wait-power-on@0.service
5.
op-power-start@0.service
is to call the PowerControl service to DC on. And op-wait-power-on@0.service is to wait for PGood after DC on.
6.
After that (DC is on and PGood is OK),
start_host@0.service is to start the host CPU.
Best regards,
Tim

I need ask you another advice.
I use the romulus recipes to build BMC firmware. And use this fw to the X86 motherboard + AST2500.
The romulus is base on openpower. And my platform is X86 motherboard.
Is it feasible that using romulus BMC firmware to X86 motherboard, specially the power control part?
Would you have better suggestion?
Looking forward to your replay.
