 /** @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
