Routine Description:

Dispatch function for a Power Button SMI handler.

Arguments:
|
|
DispatchHandle - Handle of this dispatch function.
|
|
DispatchContext - Pointer to the dispatch function's context.
|
|
The DispatchContext fields are filled in
|

|
invoking this dispatch function.

|
Routine Description:
|
|
Register a child SMI source dispatch function with a parent SMM driver
|
|
|
|
Arguments:
|
|
This - Protocol instance pointer.
|
|
DispatchFunction - Pointer to dispatch function to be invoked for
|
|
this SMI source
|
|
DispatchContext - Pointer to the dispatch function's context.
|
|
The caller fills this context in before calling
|
|
the register function to indicate to the register
|
|
function the Power Button SMI phase for which the dispatch
|
|
function should be invoked.
|
|
DispatchHandle - Handle of dispatch function, for when interfacing
|
|
with the parent Sx state SMM driver.
|
|
|
|
Returns:
|
|
EFI_SUCCESS - The dispatch function has been successfully
|
|
registered and the SMI source has been enabled.
|
|
EFI_DEVICE_ERROR - The driver was unable to enable the SMI source.
|
|
EFI_OUT_OF_RESOURCES - Not enough memory (system or SMM) to manage this
|
|
child.
|
|
EFI_INVALID_PARAMETER - DispatchContext is invalid. The Power Button SMI
|
|
phase is not within valid range.
