+ This service is a wrapper for the UEFI Runtime Service ResetSystem().
+
+ The ResetSystem()function resets the entire platform, including all processors and devices,and reboots the system.
+ Calling this interface with ResetType of EfiResetCold causes a system-wide reset. This sets all circuitry within
+ the system to its initial state. This type of reset is asynchronous to system operation and operates without regard
+ to cycle boundaries. EfiResetCold is tantamount to a system power cycle.
+ Calling this interface with ResetType of EfiResetWarm causes a system-wide initialization. The processors are set to
+ their initial state, and pending cycles are not corrupted. If the system does not support this reset type, then an
+ EfiResetCold must be performed.
+ Calling this interface with ResetType of EfiResetShutdown causes the system to enter a power state equivalent to the
+ ACPI G2/S5 or G3 states. If the system does not support this reset type, then when the system is rebooted, it should
+ exhibit the EfiResetCold attributes.
+ The platform may optionally log the parameters from any non-normal reset that occurs.
+ The ResetSystem() function does not return.
+
+ @param ResetType The type of reset to perform.
+ @param ResetStatus The status code for the reset. If the system reset is part of a normal operation, the status code
+ would be EFI_SUCCESS. If the system reset is due to some type of failure the most appropriate EFI
+ Status code would be used.
+ @param DataSizeThe size, in bytes, of ResetData.
+ @param ResetData For a ResetType of EfiResetCold, EfiResetWarm, or EfiResetShutdown the data buffer starts with a
+ Null-terminated Unicode 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. ResetData
+ is only valid if ResetStatus is something other then EFI_SUCCESS. This pointer must be a physical
+ address. For a ResetType of EfiRestUpdate the data buffer also starts with a Null-terminated string
+ that is followed by a physical VOID * to an EFI_CAPSULE_HEADER.

- This service is a wrapper for the UEFI Runtime Service ResetSystem().
-
- The ResetSystem()function resets the entire platform, including all processors and devices,and reboots the system.
- Calling this interface with ResetType of EfiResetCold causes a system-wide reset. This sets all circuitry within
- the system to its initial state. This type of reset is asynchronous to system operation and operates without regard
- to cycle boundaries. EfiResetCold is tantamount to a system power cycle.
- Calling this interface with ResetType of EfiResetWarm causes a system-wide initialization. The processors are set to
- their initial state, and pending cycles are not corrupted. If the system does not support this reset type, then an
- EfiResetCold must be performed.
- Calling this interface with ResetType of EfiResetShutdown causes the system to enter a power state equivalent to the
- ACPI G2/S5 or G3 states. If the system does not support this reset type, then when the system is rebooted, it should
- exhibit the EfiResetCold attributes.
- The platform may optionally log the parameters from any non-normal reset that occurs.
- The ResetSystem() function does not return.
-
- @param ResetType The type of reset to perform.
- @param ResetStatus The status code for the reset. If the system reset is part of a normal operation, the status code
- would be EFI_SUCCESS. If the system reset is due to some type of failure the most appropriate EFI
- Status code would be used.
- @param DataSizeThe size, in bytes, of ResetData.
- @param ResetData For a ResetType of EfiResetCold, EfiResetWarm, or EfiResetShutdown the data buffer starts with a
- Null-terminated Unicode 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. ResetData
- is only valid if ResetStatus is something other then EFI_SUCCESS. This pointer must be a physical
- address. For a ResetType of EfiRestUpdate the data buffer also starts with a Null-terminated string
- that is followed by a physical VOID * to an EFI_CAPSULE_HEADER.

- attributes are not additive in nature.
-
- @param Attributes Attributes bitmask to specify the type of variables on
- which to return information. Refer to the
- GetVariable() function description.
- @param MaximumVariableStorageSize
- On output the maximum size of the storage space
- available for the EFI variables associated with the
