[Xen-devel] Question about the XEN platform pci

["Wu, Bob" <Bob.Wu@xxxxxxx>]

 

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
