BmcElog

Overview

BMC Event Log (SEL) driver that provides read, write, clear, and status operations for the IPMI System Event Log via the BMC. Implements the BMC_ELOG_REFROTOCOL for SEL management, handling SEL reservation, entry addition, erase operations, and enable/disable toggling through the IPMI transport protocol.

Key Functions

• BmcElogEntryPoint -- Module initialization, protocol installation
• BmcElogRead -- Read SEL entries via IPMI Get SEL Entry commands
• BmcElogWrite -- Write entries to SEL via Add SEL Entry
• BmcElogClear -- Reserve and erase SEL operations
• BmcElogSetStatus -- Enable/disable SEL logging
• IpmiDetectInterface -- Detect BMC interface type (KCS/SMBUS/BT)
• IpmiSendCommand / IpmiGetResponse -- IPMI transport wrappers
• OnExitBootServices / OnVirtualAddressChange -- Runtime event handlers
• DebugAssert -- Debug assertion via IPMI transport

Dependencies

• gEfiIpmiTransportProtocolGuid -- IPMI transport protocol
• gEfiBmcElogProtocolGuid -- BMC event log protocol
• gEfiHobListGuid -- HOB list for startup configuration

Platform

Intel Purley (Xeon Scalable) with BMC (AST2500). x86-64 UEFI Runtime Driver.
