Hi all,

I've compiled vanilla kernel 2.6.7 just today, and I've noticed that my KT600 AGP chipset is identified ad CLE266 :

Linux agpgart interface v0.100 (c) Dave Jones
agpgart: Detected VIA CLE266 chipset
agpgart: Maximum main memory to use for agp memory: 438M
agpgart: AGP aperture is 256M @ 0xc0000000

is this a bug or is normal?

Bye

Marcello

Hi all,
I've compiled vanilla kernel 2.6.7 just today, and I've noticed that my KT600 AGP chipset is identified ad CLE266 :
Linux agpgart interface v0.100 (c) Dave Jones
agpgart: Detected VIA CLE266 chipset
agpgart: Maximum main memory to use for agp memory: 438M
agpgart: AGP aperture is 256M @ 0xc0000000

Can you apply this..
http://www.codemonkey.org.uk/projects/bitkeeper/agpgart/agpgart-2004-06-17.diff

on top, and see if it fixes itself ? There was a missing table entry, which could have caused all the subsequent entries to be off by one. (And CLE266 is the entry before the KT600)

Thanks, this patch seems to solve the problem , now my system is detected as :

Linux agpgart interface v0.100 (c) Dave Jones
agpgart: Detected VIA KT400/KT400A/KT600 chipset
agpgart: Maximum main memory to use for agp memory: 438M
agpgart: AGP aperture is 256M @ 0xc0000000

Thanks again
