总线上发生两类事件可以导致设备与驱动绑定行为的发生:一是通过device_register函数向某一bus上注册设备,这种情况下内核除了将该设备加入到bus上设备链表的尾端,同时会试图将此设备与总线上所有驱动对象进行绑定操作;二是通过driver_register将某一驱动注册到其所属的bus上,内核此时除了将驱动对象加入到bus所有驱动对象构...
use the registry information provided by the PCI bus driver instead of driver code that scans the PCI bus. To allow PCI enumeration of all PCI devices, update the registry for your OS design.
// Update the Bus Range // RootBridge->ResAllocNode[TypeBus].Base = Descriptor->AddrRangeMin; RootBridge->ResAllocNode[TypeBus].Length = Descriptor->AddrLen; RootBridge->ResAllocNode[TypeBus].Status = ResAllocated; return EFI_SUCCESS; } 1. 2. 3. 4. 5. 6. 7. 8. 更新当前RootBridg...
-->pcibios_update_irq(pci_dev,irq) //将irq号写入pci设备的配置空间PCI_INTERRUPT_LINE //注意,这里寄存器只是用来保存结果,例如把其值8改为9,并不能改变中断号 (3)PCI结构树有了,现在构建PCI的资源树,有冲突就修改 -->pcibios_allocate_bus_resource() ...
6.由于 Bridge 1 所能访问到的最大 Bus 编号也是 2,因此重新设置 Bridge 1 的 Subordinate Bus Number 寄存器为 2。 7.总线编号结束。 3.Linux内核PCI数据结构 内核(linux-2.6.24) 提供了三类数据结构用以描述 PCI 控制器、PCI 设备以及 PCI 总线。
pci_bus_alloc_resource pci_update_resource pci_std_update_resource pci_write_config_dword(dev, reg,new)//往BAR寄存器写入起始地址 BAR寄存器中写入的地址,乍一看就是系统的物理地址,但实际上,它与CPU域的物理地址有所不同,它是PCI域的物理地址。两个域的地址需要通过Host bridge的转换。只不过,X86上Host...

To allow PCI enumeration of all PCI devices, update the registry for your OS design.To enable the PCI bus driver support in your Windows Embedded Compact-based OS design, select the PCI bus catalog item provided with Windows Embedded Compact....
The restore worked well, but when I checked Device Manager, I found that the PCI Memory & SM Bus Controllers did not have the driver updates they need (see screenshots). I tried the device manager update utilities, but they could not find any drivers. I then utilized...
