PROTOCOLS
DriverManagerRegistration
Defined in fuchsia.power.manager/register.fidl
Protocol for the Driver Manager to register the required protocol instances with the Power Manager.
Register
Registers a [fuchsia.device.manager/SystemStateTransition] and [fuchsia.io.Directory] with the Power Manager. The Power Manager expects to receive this call exactly once and it will be inoperable until the call is made successfully. If the call succeeds, the DriverManagerRegistration channel will no longer serve any purpose and may be closed. If the call fails, the Power Manager will leave the channel open and await a retry.
- request
system_state_transitiona [fuchsia.device.manager/SystemStateTransition] that allows the Power Manager to set the Driver Manager termination behavior. This is an essential piece involved in coordinating orderly system shutdown. - request
dira [fuchsia.io.Directory] that represents the devfs (/dev) served by the Driver Manager.
- error a [fuchsia.power.manager.Error] value indicating the reason (if any) that Register failed.
