Sorry bother, I read the XEN source code recently, and found the XEN platform PCI code under drivers/xen/platform-pci.c, and I can't fully under this driver's affect, can anybody explain a little for me?
Is the platform PCI driver for PV-split-PCI-driver-model such as the pci-frontend/pci-backend? or for PCI pass-through model? Or for other purpose? I saw the xenbus_pcifront_driver/ xenbus_xen_pcibk_driver are registered on XENBUS, so I guess the platform-PCI-driver is not for PV PCI driver. Really thank you for your replay. Thanks, Bob
