Field Documentation

EFI_PHYSICAL_ADDRESS EFI_GCD_IO_SPACE_DESCRIPTOR::BaseAddress

Physical address of the first byte in the I/O region.

Type EFI_PHYSICAL_ADDRESS is defined in the AllocatePages() function description in the UEFI 2.0 specification.

Definition at line 116 of file PiDxeCis.h.

UINT64 EFI_GCD_IO_SPACE_DESCRIPTOR::Length

Number of bytes in the I/O region.

Definition at line 121 of file PiDxeCis.h.

EFI_GCD_IO_TYPE EFI_GCD_IO_SPACE_DESCRIPTOR::GcdIoType

Type of the I/O region.

Type EFI_GCD_IO_TYPE is defined in the AddIoSpace() function description.

Definition at line 127 of file PiDxeCis.h.

EFI_HANDLE EFI_GCD_IO_SPACE_DESCRIPTOR::ImageHandle

The image handle of the agent that allocated the I/O resource described by PhysicalStart and NumberOfBytes.

If this field is NULL, then the I/O resource is not currently allocated. Type EFI_HANDLE is defined in InstallProtocolInterface() in the UEFI 2.0 specification.

Definition at line 135 of file PiDxeCis.h.

EFI_HANDLE EFI_GCD_IO_SPACE_DESCRIPTOR::DeviceHandle

The device handle for which the I/O resource has been allocated.

If ImageHandle is NULL, then the I/O resource is not currently allocated. If this field is NULL, then the I/O resource is not associated with a device that is described by a device handle. Type EFI_HANDLE is defined in InstallProtocolInterface() in the UEFI 2.0 specification.
