UbaConfigDatabaseDxe

Overview

UbaConfigDatabaseDxe implements a UEFI driver that provides a configuration database service for the Lenovo UBA (Universal BIOS Architecture) framework. It stores, retrieves, and manages configuration data identified by GUIDs, persisted via HOB (Hand-Off Block) during the DXE phase. The driver installs a protocol interface with three main operations: GetInfo, SetData, and GetData for GUID-keyed configuration entries.

Key Functions

• UbaConfigDatabaseDriverEntry -- Main entry point; installs the config database protocol
• UbaConfigDatabaseGetInfo -- Returns metadata about a GUID-keyed configuration entry
• UbaConfigDatabaseSetData -- Stores configuration data for a given GUID
• UbaConfigDatabaseGetData -- Retrieves configuration data for a given GUID
• UbaConfigDatabaseInitFromHob -- Initializes the database from HOB data passed from PEI phase

Dependencies

• gUbaConfigDatabaseProtocolGuid -- UBA configuration database protocol (produced)
• HOB services -- Hand-Off Block retrieval for configuration data
• UEFI Boot Services -- Memory allocation and protocol installation
