Hi guys, In XEN HVM guest, there is always an emulated PIIX3 ISA bridge on slot 01.0. This shadows the PCH ISA bridge on 1f.0 with the current intel_detect_pch() implementation. The issue can be easily solved by looping through all the ISA bridges until the first match is found, instead of just ch

Hi all, I'm running IGD pass through on xen and only get partial success. Basically PVHVM guest works while HVM guest (windows, linux without pvops compiled in) does not. I'm trying to figure out what's the missing piece in xen and need help from you experts. I managed to capture some logs for both
