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_...
本文介绍PCI Express Port Bus driver基础知识,如何使能注册和反注册PCI Express Port Bus Driver. 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...
device可以在任何时刻出现,而driver 也可以在任何时刻被加载,所以,出现的情况就是,每当一个struct device诞生,它就会去bus的drivers链表中寻找自己的另一半,反之,每当一个一个struct device_driver诞生,它就去bus的devices链表中寻找它的那些设备。如果找到了合适的,那么ok,和之前那种情况一下,调用 device_bind_driver...
pci总线驱动的EFI_DRIVER_BINDING_PROTOCOL是在PciBusEntryPoint中安装的,这个时间点处于DXE阶段。 Supported() PciBusDriverBindingSupported()判断某个控制器是否支持Pci 总线驱动是通过打开控制器的EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL和EFI_DEVICE_PATH_PROTOCOL,如果都打开成功,说明控制器安装了EFI_PCI_ROOT_BRIDGE_IO_...
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...

蓝屏代码0x000000A1表示“PCI_BUS_DRIVER_INTERNAL”，表明系统检测到PCI总线驱动程序内部错误。这可能是由于驱动程序损坏、版本不匹配、硬件故障或操作系统问题等原因引起的。详细检查有助于确定具体原因。为了诊断和修复，可以尝试以下步骤：首先，在命令提示符下运行chkdsk /f命令，检查和修复硬盘上的错误。
3/26/2014Learn about PCI bus driver support in Windows Embedded Compact 2013. This topic includes links to reference and samples.The PCI bus is a common technology used on many embedded devices. PCI bus support makes it possible to include a wide variety of inexpensive PCI devices on embedded...
Abus driverservices a bus controller, adapter, or bridge (see thePossible Driver Layersfigure). Microsoft provides bus drivers for most common buses, such as PCI, PnpISA, SCSI, and USB. Other bus drivers can be provided by IHVs or OEMs. Bus drivers are required drivers; there is one bus...
