Detailed Description

The EFI_PCI_IO_PROTOCOL provides the basic Memory, I/O, PCI configuration, and DMA interfaces used to abstract accesses to PCI controllers. There is one EFI_PCI_IO_PROTOCOL instance for each PCI controller on a PCI bus. A device driver that wishes to manage a PCI controller in a system will have to retrieve the EFI_PCI_IO_PROTOCOL instance that is associated with the PCI controller.

◆ RomImage

VOID* _EFI_PCI_IO_PROTOCOL::RomImage

A pointer to the in memory copy of the ROM image. The PCI Bus Driver is responsible for allocating memory for the ROM image, and copying the contents of the ROM to memory. The contents of this buffer are either from the PCI option ROM that can be accessed through the ROM BAR of the PCI controller, or it is from a platform-specific location. The Attributes() function can be used to determine from which of these two sources the RomImage buffer was initialized.

◆ RomSize

UINT64 _EFI_PCI_IO_PROTOCOL::RomSize

The size, in bytes, of the ROM image.

◆ SetBarAttributes

EFI_PCI_IO_PROTOCOL_SET_BAR_ATTRIBUTES _EFI_PCI_IO_PROTOCOL::SetBarAttributes

◆ Unmap
