Overview

SMM PCI Root Bridge I/O access driver. The recovered code provides a PCI
configuration-space abstraction that can run from SMM, including legacy
CF8/CFC access, PCIe enhanced configuration, bus translation, and teardown
paths for runtime and S3 resume.

Key Functions

ModuleEntryPoint — SMM entry; library init and PCI RbIo setup.
SmmPciRbIoLibraryConstructor — AutoGen library constructor.
SmmPciRbIoInitialize — Core PCI Root Bridge I/O initialization.
SmmPciRbIoLibraryDestructor — Library destructor.
SmmPciRbIoUnload — Manual unload/unregister handler.
SmmPciRbIoFailurePath — Failure-path handler.
SmmPciRbIoNeedsInitialization — Early PCI configuration-space enumeration gate.
SmmPciRbIoAssertionFailure — AutoGen assertion/guard fallback path.
