Detailed Description

Structure describing a MMRAM region and its accessibility attributes.

Field Documentation

◆ PhysicalStart

EFI_PHYSICAL_ADDRESS EFI_MMRAM_DESCRIPTOR::PhysicalStart

Designates the physical address of the MMRAM in memory.

This view of memory is the same as seen by I/O-based agents, for example, but it may not be the address seen by the processors.

Definition at line 124 of file PiMultiPhase.h.

◆ CpuStart

EFI_PHYSICAL_ADDRESS EFI_MMRAM_DESCRIPTOR::CpuStart

Designates the address of the MMRAM, as seen by software executing on the processors.

This address may or may not match PhysicalStart.

Definition at line 129 of file PiMultiPhase.h.

◆ PhysicalSize

UINT64 EFI_MMRAM_DESCRIPTOR::PhysicalSize

Describes the number of bytes in the MMRAM region.

Definition at line 133 of file PiMultiPhase.h.

◆ RegionState

UINT64 EFI_MMRAM_DESCRIPTOR::RegionState

Describes the accessibility attributes of the MMRAM.

These attributes include the hardware state (e.g., Open/Closed/Locked), capability (e.g., cacheable), logical allocation (e.g., allocated), and pre-use initialization (e.g., needs testing/ECC initialization).
