Description Rafal Zawadzki 2006-03-15 17:30:04 UTC
There is no support for AGP VIA PT880 ULTRA on amd64 architecture (EM64T). Module via-agp (which contains support for PT 880 ULTRA) has x86_32 dependency. So, there is no 3d acceleration under 64bit Open Suse using chipset with pt880 ultra.

Greg, can you look into this please? Is this just a matter of removing
the dependency on X86_32, or is there a real 64bit cleanliness issue with
the via-agp.c?
Comment 3 Rafal Zawadzki 2006-03-17 17:30:31 UTC
It 64 bit issue. I've already tried to remove x86_32 dependency - for the first look everything looks ok - agpgart  detect my chipset, fglrx / radeon driver too. But first try of using it (glxinfo, glxgears, any opengl stuff) hangs the computer.
Comment 4 Greg Kroah-Hartman 2006-03-17 22:05:27 UTC
Yeah, I don't think there's really anything we can do about it here, sorry.

That device is just unsuported right now for amd64.  Try asking the AGP maintainer
on the linux-kernel mailing list about it if you want to try to get it to work
in the future.
Comment 5 Rafal Zawadzki 2006-03-19 09:17:24 UTC
I tried writing to agp maintainer Dave Jones, without effect - I was ignored. IMVHO big companies (like Novell) got much more persuadion power than normal mortal :(
Comment 6 Greg Kroah-Hartman 2006-04-12 17:15:15 UTC
Sorry, but no, we do not have more influence than "normal" people do.

There's not much we can do here, sorry.
