I'm trying to compile the 2.4.23 kernel for my new Athlon64 processor. I select the 'Opteron/Athlon64/Hammer/K8' processor type and all appears to go well, but it still compiles '-march=athlon'. Also, when I do 'make menuconfig' again, the pocessor type has been set back to 'Athlon/Duron/K7'. Does anyone have a clue about what's causing this? Is the Athlon64 Processor not yet fully supported in 2.4.23?
The kernel works fine, by the way, but I'd like to optimize it for my processor.

Thanks in advance.

i don't have an opteron so i don't know, but perhaps try a 2.6 kernel?

maybe in the 2.4.23 kernel, 64-bit processors aren't fully implemented and is just a choice to avoid confusing users.

All goes fine when compiling the 2.6 kernel, but I'm having trouble compiling my ethernet driver with that kernel. That's why I wanted to stick with the 2.4.23.

look for the "forcedeth" patch, its an open source driver for the nvidia network card thats most likely the one on your motherboard. you can get it here ----> http://www.hailfinger.org/carldani/l...hes/forcedeth/

then copy the patch to your /usr/src/linux-2.6.0 directory, and use the patch command

"patch -p1 < patchname"

to patch the kenel

p.s. they have a driver for both the 2.4.xx and the 2.6.xx kernels

Yup, that's my ethernet controller. Thanks a bunch, I'm off to try it right away! If it works I can finally start using my 2.6.0 kernel...

Sorry to say, you will need a copy of binutils that supports x86_64 code. You can download it from www.kernel.org and compile it to support your athlon64. Unfortunately I don't know much as I also recently purchased an athlon64 laptop and am new at this. I think that to compile for this processor you need to add an 'ARCH=x86_64' at the end of your make commands.

make menuconfig ARCH=x86_64
make all modules_install ARCH=x64_64

Then you'd fetch your bzImage from the arch/x86_64/ directory.

This is my guess, I've got more to sift through, like...
cc1: error: code model 'kernel' not supported in the 32 bit mode

good luck, I'll need it too...

One more thing, you might want to download gcc-3.4.1. It supports the -march=athlon64 option.
