Function Documentation

◆ BuildMemoryMapFromResDescHobs()

VOID BuildMemoryMapFromResDescHobs ( OUT MM_CPU_MEMORY_REGION **  MemoryRegion,
OUT UINTN *  MemoryRegionCount 
)

Build Memory Region from ResourceDescriptor HOBs by excluding Logging attribute range.

Parameters
[out]MemoryRegionReturned Non-Mmram Memory regions.
[out]MemoryRegionCountA pointer to the number of Memory regions.

Definition at line 120 of file NonMmramMapStandaloneMm.c.

◆ CreateExtendedProtectionRange()

VOID CreateExtendedProtectionRange ( OUT MM_CPU_MEMORY_REGION **  MemoryRegion,
OUT UINTN *  MemoryRegionCount 
)

Build extended protection MemoryRegion.

The caller is responsible for freeing MemoryRegion via FreePool().

Parameters
[out]MemoryRegionReturned Non-Mmram Memory regions.
[out]MemoryRegionCountA pointer to the number of Memory regions.

Definition at line 188 of file NonMmramMapStandaloneMm.c.

◆ CreateNonMmramMemMap()

VOID CreateNonMmramMemMap ( IN UINT8  PhysicalAddressBits,
OUT MM_CPU_MEMORY_REGION **  MemoryRegion,
OUT UINTN *  MemoryRegionCount 
)

Create the Non-Mmram Memory Region within the ResourceDescriptor HOBs without Logging attribute.

The caller is responsible for freeing MemoryRegion via FreePool().

Parameters
[in]PhysicalAddressBitsThe bits of physical address to map.
[out]MemoryRegionReturned Non-Mmram Memory regions.
[out]MemoryRegionCountA pointer to the number of Memory regions.

Definition at line 207 of file NonMmramMapStandaloneMm.c.

◆ GetSmmProfileData()

EFI_PHYSICAL_ADDRESS GetSmmProfileData ( IN OUT UINT64 *  Size)

Get SmmProfileData.

Parameters
[in,out]SizeReturn Size of SmmProfileData. 0 means the gMmProfileDataHobGuid does not exist.
Returns
Address of SmmProfileData

Definition at line 20 of file NonMmramMapStandaloneMm.c.

◆ IsNonMmramLoggingAddress()

BOOLEAN IsNonMmramLoggingAddress ( IN UINT64  Address)

Parameters
[in]Addressthe address to be checked
Returns
TRUE The address is the NonMmram logging Address.
FALSE The address is not the NonMmram logging Address.

Definition at line 62 of file NonMmramMapStandaloneMm.c.

◆ IsSmmCommBufferForbiddenAddress()

BOOLEAN IsSmmCommBufferForbiddenAddress ( IN UINT64  Address)
