PCIe Port bus driver 所处PCIe软件架构位置如下图红色。 PCI Express Port Bus Driver作用 PCIe port包含Root Port and the Switch Port, switch port又分为Upstream Port和Downstream Port。PCIe port通常提供多个高级服务,如native hotplug support (HP), power management event support (PME), advanced error ...
PCI总线驱动是一个遵循UEFI驱动模型的特殊驱动，它需要实现EFI_DRIVER_BINDING_PROTOCOL，该协议由Supported(), Start(), Stop()函数和Version, ImageHandle, DriverBindingHandle等元素构成。驱动绑定结构在PciBusEntryPoint安装，通常在DXE阶段。Supported()函数用于判断控制器是否支持PCI总线驱动，通过检查EFI_...
PCIe Port Bus Driver负责创建PCIe Port驱动设备、申请中断以及为高级服务做好准备。在drivers/pci/pcie/portdrv_pci.c文件中，支持设备类型包括PCI-Express port、PCI-to-PCI bridge、Root Complex Event Collector。关键接口为pcie_port_device_register，用于申请用于Hotplug、AER、DPC、PME等高级服务的中...

系统启动后,会调用buses_init()函数创建/sys/bus文件目录,这部分系统在开机是已经帮我们准备好了,接下去就是通过总线注册函数bus_register()进行总线注册,注册完成后,在/sys/bus目录下生成device文件夹和driver文件夹,最后分别通过device_register()以及driver_register()函数注册对应的设备和驱动。
最新的4.12内核中对pci host driver进行一些划分,把基于designware IP的主控驱动放到drivers/pci/dwc目录下去了。如果是基于老的kernel开发,想要移植新版的内核的话,要注意,同时多了designware ep驱动框架。 非designware的主控驱动还是位于host目录下,譬如pcie-xilinx.c。
