Function Documentation

◆ ResetCold()

VOID EFIAPI ResetCold ( VOID )

This function causes a system-wide reset (cold reset), in which all circuitry within the system returns to its initial state. This type of reset is asynchronous to system operation and operates without regard to cycle boundaries.

If this function returns, it means that the system does not support cold reset.

Definition at line 23 of file DxeResetSystemLib.c.

◆ ResetPlatformSpecific()

VOID EFIAPI ResetPlatformSpecific	(	IN UINTN	DataSize,
		IN VOID *	ResetData
	)

This function causes a systemwide reset. The exact type of the reset is defined by the EFI_GUID that follows the Null-terminated Unicode string passed into ResetData. If the platform does not recognize the EFI_GUID in ResetData the platform must pick a supported reset type to perform.The platform may optionally log the parameters from any non-normal reset that occurs.

Parameters

[in]	DataSize	The size, in bytes, of ResetData.
[in]	ResetData	The data buffer starts with a Null-terminated string, followed by the EFI_GUID.

Definition at line 73 of file DxeResetSystemLib.c.

◆ ResetShutdown()

VOID EFIAPI ResetShutdown ( VOID )

This function causes the system to enter a power state equivalent to the ACPI G2/S5 or G3 states.

If this function returns, it means that the system does not support shut down reset.

◆ ResetSystem()

VOID EFIAPI ResetSystem	(	IN EFI_RESET_TYPE	ResetType,
		IN EFI_STATUS	ResetStatus,
		IN UINTN	DataSize,
		IN VOID *ResetData	OPTIONAL
	)

The ResetSystem function resets the entire platform.

Parameters

[in]	ResetType	The type of reset to perform.
[in]	ResetStatus	The status code for the reset.
[in]	DataSize	The size, in bytes, of ResetData.
[in]	ResetData	For a ResetType of EfiResetCold, EfiResetWarm, or EfiResetShutdown the data buffer starts with a Null-terminated string, optionally followed by additional binary data. The string is a description that the caller may use to further indicate the reason for the system reset.

Definition at line 95 of file DxeResetSystemLib.c.

◆ ResetWarm()

VOID EFIAPI ResetWarm ( VOID )

This function causes a system-wide initialization (warm reset), in which all processors are set to their initial state. Pending cycles are not corrupted.

If this function returns, it means that the system does not support warm reset.
