Surely it's not too big a job to get basic, generic AGP3 support into 2.4, even if it's not optimised? If it's non-trivial to make all AGP3 features work in 2.4, then it's reasonable to require 2.6 for "better performance". To be honest, I'd at least expect a fallback to AGP2 for hardware that can support it, such as KT400. The Windows drivers for my ATI card can tell the hardware to drop to "AGP 4x" (which I believe implies AGP2 - I could be wrong), and the card *did* work correctly with the KT266A chipset I was using before. > Yes, I could use 2.6-x and help test that, but like so many people, I > need to have something reliable so I can get some work done. FWIW, I installed 2.6.0-test3 and it seems to work well. After grabbing a later version of the ATI drivers (which are needed for 2.6 compatibility), the AGP was set up correctly and I'm back in X. I'm not seeing any stability problems so far. However, I did encounter a compilation problem with one of the USB device drivers - not a major problem at present since that particular device is attached to a different machine - but it does show that 2.6 isn't ready for primetime yet. The major distros aren't going to make that switch for a while. -------------------------------------------------------------- from: Jonathan "Chromatix" Morton mail: chromi@chromatix.demon.co.uk website: http://www.chromatix.uklinux.net/ tagline: The key to knowledge is not to rely on people to teach you it. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
