SmbiosRpTable

Index: 0342 | Size: 4,352 bytes | Arch: x64 | Phase: DXE

Overview

SmbiosRpTable allocates an ACPI NVS communication buffer and installs an SMBIOS Type 133 record pointing to that buffer for BIOS-to-OS communication. It locates the SMBIOS protocol, publishes the Type 133 record containing the buffer physical address, and initializes HII-related protocols (database, string, config routing, font, image) during its entry point.

Key Functions

• ModuleEntryPoint -- Locates SMBIOS protocol and dispatches Type 133 record installation
• UefiMainEntry -- Initializes UEFI globals, HOB list, and HII protocol resolution
• SmbiosType133RecordInstall -- Allocates ACPI NVS buffer and installs SMBIOS Type 133 record
• ZeroMem / ZeroMemAligned64 -- 8-byte aligned memory zero-fill helpers
• DebugPrint / DebugAssert / ReadUnaligned64 -- Debug and memory utilities

Dependencies

• UEFI Boot Services / Runtime Services Table Library
• EFI_SMBIOS_PROTOCOL (locate)
• HII Protocols (Database, String, ConfigRouting, Font, Image)
• ACPI NVS memory allocation
• HOB list from PEI phase
