I thought I'd give the 2.6 series a chance today, so I emerged gentoo-dev-sources-2.6.3. Everything works fine, except that for some reason the kernel sets AGP to 0x. I do not have this problem in 2.4.x.
When configuring my TNT2-card I followed this guide.
I figured the problem lies in the kernel since I get different output from dmesg in the different kernels.
linux-2.4.22-gentoo-r7:
| Code: | $ dmesg | grep agpgart
Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 262M
agpgart: Detected Via Apollo Pro KT133 chipset
agpgart: AGP aperture is 256M @ 0xc0000000 |
linux-2.6.3-gentoo-r1:
| Code: | $ dmesg | grep agpgart
Linux agpgart interface v0.100 (c) Dave Jones
agpgart: Detected VIA Twister-K/KT133x/KM133 chipset
agpgart: Maximum main memory to use for agp memory: 262M
agpgart: AGP aperture is 256M @ 0xc0000000
agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0.
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: Found an AGP 2.0 compliant device at 0000:00:00.0.
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 |
Also, checking the files in /proc/driver/nvidia/agp/ give different results only in the status file.

It's a little annoying not having that increase in desktop performance that 2.6.x is supposed to give. With AGP 0x X is really slow when drawing things.
Anybody have any ideas what to do? |
