[Dri-users] agp 4x, setpci bus mastering questions

[Joel U. <uck...@no...>]

Two questions perhaps someone can help me with:

1. When I include 'Option "AGPMode" "4"' in the Device section for my 
Voodoo4 in my XF86Config-4, X tells me this:

(WW) TDFX(0): Option "AGPMode" is not used

So how do I get the Voodoo4 to run in 4x mode? How do I check what mode 
it's running in at all? glxinfo doesn't tell me.

2. According to 9.1 in the Users' Guide, I need to enable bus mastering for 
my card. Here's what I did:

# setpci -s 01:00.0 4.w
0003
# setpci -s 01:00.0 4.w=0007

# setpci -s 01:00.0 4.w
0003

So what I did appears to have had no effect. (And yes, I'm doing this as 
root.) What's the deal?
