Hi Peter,
Peter Rundberg
I just got a Fujitsu Siemens Celsius V810 dual Opteron Workstation. It comes equipped with an Nvidia QuadroFX card but I am having trouble getting the machine to run properly under Linux.
The problem is that the 8151 AGP tunnel can not be found and thus the graphics card can not be found. I have tried the Suse kernel (up to and including -178) as well as 2.6.1-X8664-2. Could this be a similar problem to the one that affected the Tyan Thunder K8W (S2885) a while back when the kernel could not find the 8151 AGP tunnel because of some PCI search issue.
The board looks very similar to the Tyan 2885 both feature wise and by visual inspection but apparently it is not the same as on my 2885 everything is works as expected and the 8151 is identified correctly.
Output from lspci is as follows and as you can see there is no 8151 in sight.
On my Tyan 2885 lspci find the 8151 as can be seen below.
Any ideas?
As part of my job I've analyzed that problem a bit and yes, I also believe that this is a BIOS issue. There is a workaround that makes the AMD-8151 and the devices behind that appear in the lspci output: Boot the kernel with the parameter pci=noacpi. So I suspect that the BIOS delivers wrong ACPI tables. But even with that workaround I'm not sure if we have full graphics performance. Flightgear is going with around 70 fps, glxgears shows
1200 fps but SpecViewPerf 7.1.1 reports small frame rates.
We are still working on that and for next monday there is a conference call with Tyan and AMD scheduled to resolve this issue. As soon as I have news I'll post them here on the mailinglist.
