Field Documentation

◆ Attributes

EFI_FVB_ATTRIBUTES_2 EFI_FIRMWARE_VOLUME_HEADER::Attributes

Declares capabilities and power-on defaults for the firmware volume.

Definition at line 120 of file PiFirmwareVolume.h.

◆ BlockMap

EFI_FV_BLOCK_MAP_ENTRY EFI_FIRMWARE_VOLUME_HEADER::BlockMap[1]

An array of run-length encoded FvBlockMapEntry structures. The array is terminated with an entry of {0,0}.

Definition at line 147 of file PiFirmwareVolume.h.

◆ Checksum

UINT16 EFI_FIRMWARE_VOLUME_HEADER::Checksum

A 16-bit checksum of the firmware volume header. A valid header sums to zero.

Definition at line 128 of file PiFirmwareVolume.h.

◆ ExtHeaderOffset

UINT16 EFI_FIRMWARE_VOLUME_HEADER::ExtHeaderOffset

Offset, relative to the start of the header, of the extended header (EFI_FIRMWARE_VOLUME_EXT_HEADER) or zero if there is no extended header.

Definition at line 133 of file PiFirmwareVolume.h.

◆ FileSystemGuid

EFI_GUID EFI_FIRMWARE_VOLUME_HEADER::FileSystemGuid

Declares the file system with which the firmware volume is formatted.

Definition at line 108 of file PiFirmwareVolume.h.

◆ FvLength

UINT64 EFI_FIRMWARE_VOLUME_HEADER::FvLength

Length in bytes of the complete firmware volume, including the header.

Definition at line 112 of file PiFirmwareVolume.h.

◆ HeaderLength

UINT16 EFI_FIRMWARE_VOLUME_HEADER::HeaderLength

Length in bytes of the complete firmware volume header.

Definition at line 124 of file PiFirmwareVolume.h.

◆ Reserved

UINT8 EFI_FIRMWARE_VOLUME_HEADER::Reserved[1]

This field must always be set to zero.

Definition at line 137 of file PiFirmwareVolume.h.

◆ Revision

UINT8 EFI_FIRMWARE_VOLUME_HEADER::Revision

Set to 2. Future versions of this specification may define new header fields and will increment the Revision field accordingly.

Definition at line 142 of file PiFirmwareVolume.h.

◆ Signature

UINT32 EFI_FIRMWARE_VOLUME_HEADER::Signature

Set to EFI_FVH_SIGNATURE

Definition at line 116 of file PiFirmwareVolume.h.

◆ ZeroVector

UINT8 EFI_FIRMWARE_VOLUME_HEADER::ZeroVector[16]

The first 16 bytes are reserved to allow for the reset vector of processors whose reset vector is at address 0.
