PiSmmCommunicationSmm

Overview

PiSmmCommunicationSmm is a SMM driver from the UefiCpuPkg that establishes
communication channels between UEFI runtime and SMM. It manages the shared
buffer and protocol infrastructure that allows DXE/runtime drivers to send
requests to SMM drivers and receive responses.

The driver initializes the SMM communication protocol, sets up a global status
variable for error reporting, and registers the necessary SMI handlers.

Key Functions

• ModuleEntryPoint -- SMM driver entry point that initializes the PI SMM
  Communication protocol and registers the SMI communication handler.
