GenericElog

Overview

Generic Event Log driver that provides a unified event logging interface by dispatching read/write/status operations to registered redirect protocol handlers. Installs the EFI_GENERIC_ELOG_PROTOCOL and enumerates all handles publishing EFI_REDIR_ELOG_PROTOCOL to support multiple backend event log implementations.

Key Functions

• GenericElogEntryPoint -- Module entry, globals save, event creation
• ElogDriverInit -- Stage 1: save globals, discover HOBs, create events
• ElogDriverMain -- Stage 2: allocate local structure, install protocol, enumerate redirects
• GenericElogWriteEvent -- Dispatch write to redirect handlers
• GenericElogReadEvent -- Dispatch read to redirect handlers
• GenericElogGetStatus -- Dispatch status query to redirect handlers
• GenericElogSetStatus -- Dispatch status set to redirect handlers
• EnumerateRedirectProtocols -- Discover all redirect protocol handles
• OnExitBootServices / OnVirtualAddressChange -- Runtime event handlers

Dependencies

• gEfiGenericElogProtocolGuid -- Installed generic event log protocol
• gEfiRedirElogProtocolGuid -- Backend redirect protocol (multiple instances)
