-// Period is the minimum period of time in 100 nanosecond units that child gets called.
-// The child will be called back after a time greater than the time Period.
-//
-// SmiTickInterval is the period of time interval between SMIs. Children of this interface
-// should use this field when registering for periodic timer intervals when a finer
-// granularity periodic SMI is desired. Valid values for this field are those returned
-// by GetNextInterval. A value of 0 indicates the parent is allowed to use any SMI
-// interval period to satisfy the requested period.
-// Example: A chipset supports periodic SMIs on every 64ms or 2 seconds.
-// A child wishes schedule a period SMI to fire on a period of 3 seconds, there
-// are several ways to approach the problem:
-// 1. The child may accept a 4 second periodic rate, in which case it registers with
-// Period = 40000
-// SmiTickInterval = 20000
-// The resulting SMI will occur every 2 seconds with the child called back on
-// every 2nd SMI.
-// NOTE: the same result would occur if the child set SmiTickInterval = 0.
-// 2. The child may choose the finer granularity SMI (64ms):
-// Period = 30000
-// SmiTickInterval = 640
-// The resulting SMI will occur every 64ms with the child called back on
-// every 47th SMI.
-// NOTE: the child driver should be aware that this will result in more
-// SMIs occuring during system runtime which can negatively impact system
-// performance.
-//
-// ElapsedTime is the actual time in 100 nanosecond units elapsed since last called, a
-// value of 0 indicates an unknown amount of time.

- Routine Description:
- Returns the next SMI tick period supported by the chipset. The order
- returned is from longest to shortest interval period.
-
- Arguments:
- This - Protocol instance pointer.
- SmiTickInterval - Pointer to pointer of next shorter SMI interval
- period supported by the child. This parameter
- works as a get-first, get-next field. The first
- time this function is called, *SmiTickInterval
- should be set to NULL to get the longest SMI
- interval. The returned *SmiTickInterval should
- be passed in on subsequent calls to get
- the next shorter interval period until
- *SmiTickInterval = NULL.

- 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

- DispatchContext - Pointer to the dispatch function's context.

- 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 period input value
- is not within valid range.
