Xen devel - May 2011 - How the PCI registers are mapped from HVM to real PCI device in passthrough mode

Hi,

I started working on XEN recently.
Can anybody please explain, how the PCI configuration is mapped from HVM to
real PCI device when assigned in passthrough mode.
How the PCI config accessed made by HVM are translated to real PCI device?

Thanks & Regards,
Veerasena.
