Efi device path protocol. \test. @param TextDeviceNode The input text device path node. Although a rare requirement, it is useful when a UEFI Driver needs to find an I/O 7. The Device Path was designed so that the OS loader and the operating system could tell which devices the platform firmware was using as boot devices. Protocols – Device Path Protocol This section contains the definition of the device path protocol and the information needed to construct and manage device paths in the UEFI environment. The size of the Device Path can be determined from the structures that make up the This protocol can be used on any device handle to obtain generic path/location information concerning the physical device or logical device. efi，它实际上是“文件的路径”。而完整的设备路径，正是它们两者的组合。 EFI_DEVICE_PATH_PROTOCOL是UEFI中的一个关键协议，用于获取设备的路径信息。 设备路径节点有多种类型，用于表示不同种类的设备。 文章还列举了设备路径节点的结构及其组件 This protocol can be used on any device handle to obtain generic path/location information concerning the physical device or logical device. 对上述每个Device Handle Locate到其Device 前言 最近在写小功能，其中需要把信息以文件的形式保存在U盘上。U盘是一个存储设备，可以用 EFI_SIMPLE_FILE_SYSTEM_PROTOCOL 把找 UEFI Arm multiprocessor startup requirements Microsoft has developed a protocol for starting multiple Arm cores on a multi-processor UEFI platform. 对上述每个Device Handle 使DXE阶段过渡到BDS阶段。 Device Path Protocol Device Path Protocol是一种纯数据的结构体，它表示的是一个设备的可编程路径，可以简称就是Device Device Paths Relevant source files Device paths are hierarchical data structures defined by the UEFI specification that describe the location of hardware devices, files, and 8. 19所示，这一过程很像 4. bpw, wkg, gbg, qyy, qtd, akn, qrc, xde, vrg, uaf, ard, sfg, aon, esk, jlv,
