Overview

Core SMBIOS table management DXE driver. Provides initialization and publishing of SMBIOS v2.x ("SM") and v3.0 ("SM3") entry points, runtime table update services (add/remove/modify structures), EndOfDxe event handler to lock table regions and program legacy F-segment entry points, and producer handle tracking. Installs both PI SMBIOS and AMI SMBIOS protocols.

Key Functions

• SmbiosDriverEntryPoint -- Entry point; initializes SMBIOS table base (8KB default), entry points, and protocols
• SmbiosPiAddStructure / SmbiosPiRemoveStructure -- PI SMBIOS protocol add/remove operations
• SmbiosPiUpdateString / SmbiosPiGetNextStructure -- PI SMBIOS string update and enumeration
• SmbiosEndOfDxe -- Locks SMBIOS table, programs legacy entry point into E/F segment
• SmbiosDynamicUpdate -- Populates onboard device data and NVRAM-based structures at EndOfDxe
• UpdateSmbiosTable -- Internal add/insert/delete operation on the SMBIOS structure table

Protocols / Dependencies

• EFI_SMBIOS_PROTOCOL (PI spec) and AMI_SMBIOS_PROTOCOL (custom extensions)
• Legacy Region Protocol, Firmware Volume 2 Protocol
• MM PCI Base Protocol, PCD Protocol
• SMBIOS handle table (512 entries), producer handle tracking

Platform

HR650X, SMBIOS v2.x/v3.0 dual entry points, 8KB default table, onboard device types 41/42 support
