xHCI相关的代码,很容易发现几个貌似重要的struct类型:usb_hcd、xhci_hcd和hc_driver,还有几个全局变量xhci_pci_driver、xhci_hc_driver和xhci_pci_hc_driver,再加上PCI总线相关的类型pci_dev和pci_driver。 xhci-pci模块启动,执行xhci_pci_init函数 staticint__init xhci_pci_init(void) { xhci_init_driver(&...
echo "0000:00:04.0" > /sys/modules/xhci_pci/drivers/pci:xhci_hcd/bind 通过GDB分析源代码,可以得到如下的xhci逻辑。 可以看到,xhci驱动在初始化的过程中,调用xhci_gen_setup()来访问pci的capability,并且设置xhci结构。 同时我们也可以看到,内核通过readl()来访问pci的寄存器。 所以可以猜想,只要调用readl()...

pci-ohci 是 IEEE 1394 控制器的一种规范,可用于物理电脑主板上,用于管理 Firewire 设备,与 USB 无关。 nec-xhci 和 qemu-xhci 都是虚拟的 USB 3.0 控制器,可分别用于 NEC 和 QEMU 虚拟机中,实现高速 USB 3.0 数据传输。 综上所述,这些 USB 控制器的主要差别在于版本、用途、性能、向后兼容性等方面。
