Some dumb bridges are programmed to disobey the AGP2 spec. This is likely a BIOS misprogramming rather than poweron default, or it would be a lot more common. AGPv2 spec 6.1.9 states: "The RATE field indicates the data transfer rates supported by this device. A.G.P. devices must report all that apply." Fix them up as best we can. This will prevent errors like.. agpgart: Found an AGP 3.5 compliant device at 0000:00:00.0. agpgart: req mode 1f000201 bridge_agpstat 1f000a14 vga_agpstat 2f000217. agpgart: Device is in legacy mode, falling back to 2.x agpgart: Putting AGP V2 device at 0000:00:00.0 into 0x mode agpgart: Putting AGP V2 device at 0000:01:00.0 into 0x mode agpgart: Putting AGP V2 device at 0000:01:00.1 into 0x mode https://bugs.freedesktop.org/show_bug.cgi?id=8816 Signed-off-by: Dave Jones <davej@redhat.com> |
