*	PCI: pci-stub: add pci_stub.ids parameter	Tejun Heo	2009-09-09
\| \| \| \| \| \| \| \| \| \| \| \| \|	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	Chris Wright	2009-01-07
	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. # echo "8086 10f5" > /sys/bus/pci/drivers/pci-stub/new_id # echo -n 0000:00:19.0 > /sys/bus/pci/drivers/e1000e/unbind # echo -n 0000:00:19.0 > /sys/bus/pci/drivers/pci-stub/bind # ls -l /sys/bus/pci/devices/0000:00:19.0/driver lrwxrwxrwx 1 root root 0 2008-11-25 19:10 /sys/bus/pci/devices/0000:00:19.0/driver -> ../../../bus/pci/drivers/pci-stub Cc: "Kay, Allen M" <allen.m.kay@intel.com> Cc: "Nakajima, Jun" <jun.nakajima@intel.com> Signed-off-by: Chris Wright <chrisw@sous-sol.org> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
