Description of problem: AGP support is compiled into the kernel for Fedora Core 1 Test 1 for x86_64. Apparently, AMD 8151 support was not included. dmesg output includes "agpgart: no supported devices found.". SuSE 9.0 for AMD64 includes AMD 8151 support and correctly identifies the AGP bus during kernel loading. Steps to Reproduce: 1. boot 2. examine dmesg output Actual results: No AGP support Expected results: AGP support Additional info: Tyan Thunder K8W board, Nvidia GeForce 4 4600. AMD web site claims 8151 support has been availabe in the kernel for some time now. Probably just needs to be compiled in.
support is there, but due to a bug, it doesn't pick up the agp bridge on the tyan board (its in a different place to other amd64 boards). The fix for this is in the current -testing kernel (2163).
The Tyan board specifically has the AGP bridge tied to CPU1 instead of CPU0. While this should be a performance improvement in the future, it will take a while for everyone to understand the implications of that choice. Specifically, while the testing kernel will identify the AGPGart, it is my understanding that the nVidia drivers still will not function in this configuration. They are working on the problem.
