Re: [Xen-users] vga passthrogh on mainboards with broken ivrs tables
I'm using the bulldozer 6 core right now, and in order to get it to work I needed a BIOS update and Xen 4.4.
I know you've done the BIOS update, but it may be worth looking into the Xen unstable repository and trying that.

Hi Eric,
I still couldn't get it to work. However, since the ivrs_ioapic kernel
parameter didn't do anything (i didn't even got any log messages about
it) i've dug further into this parameter.
Sadly i found out it's not included in xen-4.3.1 and since gentoo
doesn't provide git ebuilds for xen i'll gonna wait until next xen
will be released. xen-4.4 should be release on 21.01.14 - Thats not that
far away and i guess i can wait for it :)
If you want to passthrough your graphic card i suggest you to install a older
version of xen. Personally i have my own xen-4.2.1 ebuild which don't
include XSA-36. That one works perfectly well.
If irvs_ioapic won't help with next xen I'll go back too...

Just wanting to check the basics - have you also make sure you've installed the latest BIOS update for your motherboard? Sometimes these updates contain fixes fror issues such as bad table entries.
David,
Yes, I have the latest BIOS update, F10a, for my GA-990FXA-UD3 ver1.1. PCI passthrough works fine for USB controllers but when I try to passthrough a secondary VGA card I see crash logs as copied in the attachment. If you, or any others on the list, have ideas on how to work through this issue I would be very interested in hearing them.
Thanks,
Eric
