Hi:

I have successfully leased (= passed through) an ati hd 6450 to a win7 hvm domU as the primary gfx (, but= I don't seem to have full functionality (e.g. HDCP). Currently, I ca= n 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.
