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 passing && failing system. not working reg dump: http://pastebin.com/7vyG0biu dmsg: http://pastebin.com/svWG0LdY working reg dump: http://pastebin.com/ELsabQEp dmsg: http://pastebin.com/CVrkh8S0 Both are linux 3.2.31 kernel with 2.20.14 display driver, running on i7 3770. drm.debug=0x6. I noticed some difference on register values and some failure on dmsg logs. Could you help to identify the fatal ones so that I can dig into xen source?
