[Xen-users] AMD-8131

[Sebastian Böhm <seb@xxxxxxxx>]

Hi,

I have a tyan mainboard with an AMD-8131 PCI-X Bridge.

With xen3-testing all PCI-X devices behind that bridge (and the bridge 
itself) are invisible to the xen0 kernel (in lspci).
With xen2-testing it works.


I greped the sources for 'AMD-8131' and '8131' and found that xen3 does 
not contain something, but xen2 seem to have something in it, so that it 
detects that PCI-X Bridge.
From the xen2 sources: "drivers/pci/quirks.c:           
printk(KERN_INFO "Fixing up AMD8131 IOAPIC mode\n");"
Can't I use my tyan mainboard with xen3 ?
Why this stuff in /xen/drivers/pci/* making the PCI-X-Bridge work has 
been removed in xen3 ?
Anyway I can't even use xen2, because the sava_nv driver hungs at 
initialisation (with xen3 it sata_nv works, but the tigon3 onboard 
network-chip in unavailable cause its behind that bridge).
I also tried with noapic, but no luck.


Anyone has a hint for me ?


Thank you very much in advance !

Regards
Sebastian
