Currently, I can see the 256 Byte PCI configuration space in the DomU (say if I leased the card to a linux guest and run lspci -xxxx), but is there a way to pass the full 4KBpci-e configuration space to an hvm guest? My theory is that win7 utilizes this full configuration space to complete the HDCP handshake. I am running xen 4.1.1-r2 on a gentoo dom0 (kernel 3.3.8) with vt-d, vt-x enabled chipset (MSI Z-68 and Intel i7 2600S). I have applied the ati gfx primary gpu patches. Any thoughts? thank you.
It sounds like it would require using the upstream version of QEMU that
has PCIe subsystem. Perhaps Anthony might know more..
