Typedef Documentation

◆ EDKII_PEI_SHADOW_MICROCODE

typedef EFI_STATUS(EFIAPI * EDKII_PEI_SHADOW_MICROCODE) (IN EDKII_PEI_SHADOW_MICROCODE_PPI *This, IN UINTN CpuIdCount, IN EDKII_PEI_MICROCODE_CPU_ID *MicrocodeCpuId, OUT UINTN *BufferSize, OUT VOID **Buffer)

Shadow microcode update patches to memory.

The function is used for shadowing microcode update patches to a continuous memory. It shall allocate memory buffer and only shadow the microcode patches for those processors specified by MicrocodeCpuId array. The checksum verification may be skiped in this function so the caller must perform checksum verification before using the microcode patches in returned memory buffer.

Parameters

[in]	This	The PPI instance pointer.
[in]	CpuIdCount	Number of elements in MicrocodeCpuId array.
[in]	MicrocodeCpuId	A pointer to an array of EDKII_PEI_MICROCODE_CPU_ID structures.
[out]	BufferSize	Pointer to receive the total size of Buffer.
[out]	Buffer	Pointer to receive address of allocated memory with microcode patches data in it.

Return values

EFI_SUCCESS	The microcode has been shadowed to memory.
EFI_OUT_OF_RESOURCES	The operation fails due to lack of resources.
