/** @file\r
  EFI SMM Control2 Protocol as defined in the PI 1.2 specification.\r
\r
  This protocol is used initiate synchronous SMI activations. This protocol could be published by a\r
  processor driver to abstract the SMI IPI or a driver which abstracts the ASIC that is supporting the\r
  APM port. Because of the possibility of performing SMI IPI transactions, the ability to generate this \r
  event from a platform chipset agent is an optional capability for both IA-32 and x64-based systems.\r
\r
  The EFI_SMM_CONTROL2_PROTOCOL is produced by a runtime driver. It provides  an \r
  abstraction of the platform hardware that generates an SMI.  There are often I/O ports that, when \r
  accessed, will generate the SMI.  Also, the hardware optionally supports the periodic generation of \r
  these signals.\r
