Re: [Xen-devel] [PATCH] intel gpu passthrough: Expose vendor specificpci cap on host bridge.

[<djmagee@xxxxxxxxxxxx>]

This always fails because it checks cap_type before it's set.  Moving the 
pt_pci_host_read call before the check gets rid of these messages in qemu log:

pcilib: sysfs_read: read failed: Invalid argument

Some versions of the Windows Intel GPU driver expect the vendor PCI capability 
to be there on the host bridge config space when passing through a Intel GPU.
