PeiSelStatusCode

Overview

This PEIM translates UEFI status codes into IPMI SEL (System Event Log) entries during the PEI phase. It installs a status code PPI notification handler that intercepts progress/error events and writes corresponding SEL records via the IPMI BMC interface. It includes a data type lookup table that maps status code progress/error identifiers to SEL event data, manages a linked list of pending SEL entries, and writes them to the BMC through direct IPMI command buffers.

Key Functions

• PeiSelStatusCodeEntryPoint -- Module entry point, validates PEI revision
• PeiSelStatusCodeInitEndpoint -- Locates IPMI PPI and installs status code notification
• PeiSelStatusCodeNotify -- Notification callback that records status codes to SEL
• PeiSelLookupDataType -- Maps status code type/value pairs to SEL event data
• InternalMemCopy / InternalMemSet / SetMem -- Memory utility functions

Dependencies

• PeiSelStatusCode.h (module header)
• IPMI PPI for BMC SEL transport
• PEI Services (LocatePpi / InstallPpi / NotifyPpi)
• edk2 BaseMemoryLib
