-/** @file
- Provides services to notify the PCI bus driver that some events have happened in a hot-plug controller

- This function allows the PCI bus driver to be notified to act as requested when a hot-plug event has happened on the hot-plug controller. Currently, the operations include add operation and remove operation.
- @param This A pointer to the hot plug request protocol.
- @param Operation The operation the PCI bus driver is requested to make.
- @param Controller The handle of the hot-plug controller.
- @param RemainingDevicePath The remaining device path for the PCI-like hot-plug device.
- @param NumberOfChildren The number of child handles. For an add operation, it is an output parameter.
- For a remove operation, it's an input parameter. When it contains a non-zero
- value, children handles specified in ChildHandleBuffer are destroyed. Otherwise,
- PCI bus driver is notified to stop managing the controller handle.
- @param ChildHandleBuffer The buffer which contains the child handles. For an add operation, it is an output
- parameter and contains all newly created child handles. For a remove operation, it
- contains child handles to be destroyed when NumberOfChildren contains a non-
- zero value. It can be NULL when NumberOfChildren is 0. It's the caller's
- responsibility to allocate and free memory for this buffer.
-
- @retval EFI_SUCCESS The handles for the specified device have been created or destroyed
- as requested, and for an add operation, the new handles are
- returned in ChildHandleBuffer.
- @retval EFI_INVALID_PARAMETER Operation is not a legal value.
- @retval EFI_INVALID_PARAMETER Controller is NULL or not a valid handle.
- @retval EFI_INVALID_PARAMETER NumberOfChildren is NULL.
- @retval EFI_INVALID_PARAMETER ChildHandleBuffer is NULL while Operation is remove and
- NumberOfChildren contains a non-zero value.
- @retval EFI_INVALID_PARAMETER ChildHandleBuffer is NULL while Operation is add.
- @retval EFI_OUT_OF_RESOURCES There are no enough resources to start the devices.
