Otherwise, UEFI firmware cannot get correct memory map for it. For example, SMM profile feature needs to get the completed MMIO map to protect them. v2: Consume AddMemoryMappedIoSpace() to handle the case that Local APIC memory space has already been added before. https://bugzilla.tianocore.org/show_bug.cgi?id=3D390 Cc: Laszlo Ersek Cc: Jiewen Yao Cc: Feng Tian Cc: Michael D Kinney Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jeff Fan --- UefiCpuPkg/CpuDxe/CpuDxe.c | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) diff --git a/UefiCpuPkg/CpuDxe/CpuDxe.c b/UefiCpuPkg/CpuDxe/CpuDxe.c index 925c50f..84d5f78 100644 --- a/UefiCpuPkg/CpuDxe/CpuDxe.c +++ b/UefiCpuPkg/CpuDxe/CpuDxe.c @@ -1037,6 +1037,36 @@ FreeMemorySpaceMap: } =20 /** + Add and allocate CPU local APIC memory mapped space.=20 + + @param[in]ImageHandle Image handle this driver. + +**/ +VOID +AddLocalApicMemorySpace ( + IN EFI_HANDLE ImageHandle + ) +{ + EFI_STATUS Status; + EFI_PHYSICAL_ADDRESS BaseAddress; + + BaseAddress =3D (EFI_PHYSICAL_ADDRESS) GetLocalApicBaseAddress(); + Status =3D AddMemoryMappedIoSpace (BaseAddress, SIZE_4KB, EFI_MEMORY_UC); + ASSERT_EFI_ERROR (Status); + + Status =3D gDS->AllocateMemorySpace ( + EfiGcdAllocateAddress, + EfiGcdMemoryTypeMemoryMappedIo, + 0, + SIZE_4KB, + &BaseAddress, + ImageHandle, + NULL + ); + ASSERT_EFI_ERROR (Status); +} + +/** Initialize the state information for the CPU Architectural Protocol. =20 @param ImageHandle Image handle this driver. @@ -1095,6 +1125,11 @@ InitializeCpu ( RefreshGcdMemoryAttributes (); =20 // + // Add and allocate local APIC memory mapped space + // + AddLocalApicMemorySpace (ImageHandle); + + // // Setup a callback for idle events // Status =3D gBS->CreateEventEx ( --=20 2.9.3.windows.2 _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
