Hi Vijay,

I am working on a patch to support  12v slot AC cycle in x86-powe= r-control.This can be enabled by configuring slotACPowerName in json config= file.Since you are also working on similar kind of feature in x86-power-co= ntrol, I would like bring up this discussion on mailing list to understand how these two features, and the design you p= roposed for chassis reset are intended to work together.Kindly go through m= y design changes below and share your thoughts.

I have modified the existing /xyz/openbmc_project/state/chassis0 objec= t to implement 12V On, Off, and Power Cycle for system which has 12V Slot p= ower support.


If slotACPowerName is disabled and if,

RequestedPowerTransition =3D "xyz.openbmc_project.State.Chassis.T= ransition.Off" then poweroff [existing functionality not changed]

RequestedPowerTransition =3D "xyz.openbmc_project.State.Chassis.T= ransition.On" then powerOn [existing functionality not changed]

RequestedPowerTransition =3D "xyz.openbmc_project.State.Chassis.T= ransition.PowerCycle" then PowerCycle [existing functionality not chan= ged]
 
events will be called.


 
If slotACPowerName is enabled and if,

RequestedPowerTransition =3D "xyz.openbmc_project.State.Chassis.T= ransition.Off" then 12V Ac Slot Off

RequestedPowerTransition =3D "xyz.openbmc_project.State.Chassis.T= ransition.On" then 12V Ac Slot On

RequestedPowerTransition =3D "xyz.openbmc_project.State.Chassis.T= ransition.PowerCycle" then 12V Ac Slot PowerCycle
 
events will be called.

Thanks,
Priyatharshan P
