Detailed Description

Management Mode System Table (MMST)

The Management Mode System Table (MMST) is a table that contains a collection of common services for managing MMRAM allocation and providing basic I/O services. These services are intended for both preboot and runtime usage.

Field Documentation

VOID** _EFI_MM_SYSTEM_TABLE::CpuSaveState

Points to an array, where each element is a pointer to a CPU save state. The corresponding element in CpuSaveStateSize specifies the number of bytes in the save state area. There are always NumberOfCpus entries in the array.

UINTN* _EFI_MM_SYSTEM_TABLE::CpuSaveStateSize

Points to an array, where each element describes the number of bytes in the corresponding save state specified by CpuSaveState. There are always NumberOfCpus entries in the array.

UINTN _EFI_MM_SYSTEM_TABLE::CurrentlyExecutingCpu

CPU information records A number between zero and and the NumberOfCpus field. This field designates which processor is executing the MM infrastructure.

EFI_TABLE_HEADER _EFI_MM_SYSTEM_TABLE::Hdr

The table header for the SMST.

EFI_ALLOCATE_PAGES _EFI_MM_SYSTEM_TABLE::MmAllocatePages

EFI_ALLOCATE_POOL _EFI_MM_SYSTEM_TABLE::MmAllocatePool

Runtime memory services

EFI_CONFIGURATION_TABLE* _EFI_MM_SYSTEM_TABLE::MmConfigurationTable

A pointer to the UEFI Configuration Tables. The number of entries in the table is NumberOfTableEntries.

UINT32 _EFI_MM_SYSTEM_TABLE::MmFirmwareRevision

The particular revision of the firmware.

CHAR16* _EFI_MM_SYSTEM_TABLE::MmFirmwareVendor

A pointer to a NULL-terminated Unicode string containing the vendor name. It is permissible for this pointer to be NULL.
