2 UEFI Driver Development Guide for All Hardware Device Classes Proper management of DMA addresses For some drivers, the CPU address and the PCI address do not have to be the same.</plaintext></li> <li>18.3 PCI drivers. PCI drivers use the services of the EFI_PCI_IO_PROTOCOL to produce one or more protocols providing I/O abstractions for a PCI controller. PCI drivers follow the UEFI driver model, so they may be any of the following: Device drivers. Bus drivers. Hybrid drivers.</li> <li>Instead, the device path for a PCI device is described with one or more PCI device path nodes that describe the path from the PCI root bridge, through zero or more PCI-toPCI bridges, and finally the target PCI device.

For example, a device driver for a USB device uses the service of the USB I/O Protocol, and a device driver for a PCI controller uses the services of the PCI I/O Protocol. In other words, the PCI I/O Protocol is consumed by a driver for a PCI option ROM card.</li> <li>Device I/O from the UEFI environment. 04/20/2017;. Typically, communication is established by utilizing a UEFI device driver for the given device. This driver enables the capsule update code to bind to the device via a well-known device path using the appropriate protocol.</li> <li>This "PCI ROM Priority" is in fact a priority setting that works that way, if implemented correctly: if set to "Legacy", BIOS tries to start Option ROM before EFI Driver if any, and if can be loaded, EFI Driver will not. If set to "EFI", and EFI Driver is available, Option ROM will not be started, but EFI Driver will.</li> <li>The device is powered on and runs the SoC-specific firmware boot loaders, which initialize the hardware on the device and provide emergency flashing functionality.
