/**
|
|
Provides the parent dispatch service for a given Sx source generator.
|
|
|
|
This service registers a function (DispatchFunction) which will be called when the sleep state
|
|
event specified by RegisterContext is detected. On return, DispatchHandle contains a
|
|
unique handle which may be used later to unregister the function using UnRegister().
|
|
The DispatchFunction will be called with Context set to the same value as was passed into
|
|
this function in RegisterContext and with CommBuffer and CommBufferSize set to
|
|
NULL and 0 respectively.
|
|
|
|
@param[in] This Pointer to the EFI_MM_SX_DISPATCH_PROTOCOL instance.
|
|
@param[in] DispatchFunction Function to register for handler when the specified sleep state event occurs.
|
|
@param[in] RegisterContext Pointer to the dispatch function's context.
|
|
The caller fills this context in before calling
|
|
the register function to indicate to the register
|
|
function which Sx state type and phase the caller
|
|
wishes to be called back on. For this intertace,
|
|
the Sx driver will call the registered handlers for
|
|
all Sx type and phases, so the Sx state handler(s)
|
|
must check the Type and Phase field of the Dispatch
|
|
context and act accordingly.
|
|
@param[out] DispatchHandle Handle of dispatch function, for when interfacing
|
|
with the parent Sx state MM driver.
|
|
|
|
@retval EFI_SUCCESS The dispatch function has been successfully
|
|
registered and the MMI source has been enabled.
|
|
@retval EFI_UNSUPPORTED The Sx driver or hardware does not support that
|
|
Sx Type/Phase.
|
|
@retval EFI_DEVICE_ERROR The Sx driver was unable to enable the MMI source.
|
|
@retval EFI_INVALID_PARAMETER RegisterContext is invalid. Type & Phase are not
|
|
within valid range.
|
|
@retval EFI_OUT_OF_RESOURCES There is not enough memory (system or MM) to manage this
|
|
child.
