/** @file\r
  This file declares SMM Control abstraction protocol.\r
  This protocol is used initiate SMI/PMI activations. This protocol could be published by either of\r
  the following:\r
  - A processor driver to abstract the SMI/PMI IPI\r
  - The driver that abstracts the ASIC that is supporting the APM port, such as the ICH in an\r
  Intel chipset\r
  Because of the possibility of performing SMI or PMI IPI transactions, the ability to generate this\r
  event from a platform chipset agent is an optional capability for both IA-32 and Itanium based\r
  systems.\r
