这个机制在虚拟化中使用的比较普遍,比如host机器上有一个device,正在被使用,如果要pass through给guest,就需要先从host把driver unbind掉,然后通过new id的方式,把这个device和VFIO driver绑定到一起,这样虚拟机启动时,就能通过VFIO driver访问device了。 12.1.6. Old-Style PCI Probing 在老的kernel中,driver并不...
对每个设备,都会调用pci_scan_device()执行扫描的过程,如果该设备存在,就会将该设备加入到所属总线的devices链表上.这是在pci_device_add()函数中完成的,这个函数比较简单.这里不做详细分析.我们把注意力集中到pci_scan_device(),这函数有点长,分段分析如下: static struct pci_dev * __devinit pci_scan_devic...
