◆ InitGdt()

VOID * InitGdt	(	IN UINTN	Cr3,
		OUT UINTN *	GdtStepSize
	)

Initialize Gdt for all processors.

Parameters

[in]	Cr3	CR3 value.
[out]	GdtStepSize	The step size for GDT table.

Returns: GdtBase for processor 0. GdtBase for processor X is: GdtBase + (GdtStepSize * X)

◆ InitShadowStack()

VOID InitShadowStack	(	IN UINTN	CpuIndex,
		IN VOID *	ShadowStack
	)

Initialize the shadow stack related data structure.

Parameters

CpuIndex	The index of CPU.
ShadowStack	The bottom of the shadow stack for this CPU.
