是否有通用的方法从命令行重置Linux中的PCI设备？也就是说,使PCI总线发出复位命令.

解决方法:

根据http://www.kernel.org/doc/Documentation/ABI/testing/sysfs-bus-pci,如果支持,您可以重置设备的各个功能：

What:       /sys/bus/pci/devices/.../reset
Description:
            Some devices allow an individual function to be reset
            without affecting other functions in the same device.
            For devices that have this support, a file named reset
            will be present in sysfs.  Writing 1 to this file
            will perform reset.
