      PCI: pci-stub: add pci_stub.ids parameter · b439b1d4
      Tejun Heo 提交于
      Add ids module parameter which allows specifying initial IDs for the
      pci-stub driver.  When built into the kernel, pci-stub is linked
      before any real pci drivers and by setting up IDs from initialization
      it can prevent built-in drivers from attaching to specific devices.
      
      While at it, make pci_stub_probe() print out about devices it grabbed
      to weed out "but my controller isn't being probed" bug reports.

      PCI: pci-stub module to reserve pci device · c70e0d9d
      Chris Wright 提交于
      When doing device assignment with KVM there's currently nothing to
      protect the device from having a driver in the host as well as the guest.
      This trivial module just binds the pci device on the host to a stub
      driver so that a real host driver can't bind to the device.  It has no
      pci id table, it supports only dynamic ids.
