Device Path以Device Path Node为基本单位来依次串接而成,其结束标志是End of Hardware Device Path类型的Device Path Node。下图展示了Device Path Node的基本结构: 每个Device Path Node代表某一层级的域/设备或者设备属性(比如MAC地址/IPv4地址/IPv6地址等)。通常来说,它们会按照各自所处的Subsystem的拓扑结构至顶...
在该Controller Handle下安装1个Device Path Protocol,也就是创建1个Device Path。 创建Device Path的方法是:先为该Child Device创建对应的Device Path Node,然后将该Node追加到其Parent Device的Device Path尾部形成1个新的Device Path。比如:Child Device (PCI Device=0x0, PCI Function=0x0) 是接在某个PCIe Roo...
