Doubt on which architecture to choose for kernel compilation????


hi..

I am trying to compile linux kernel 2.4.31 on my amd sempron 2500+ machine. I am in a doubt as to which processor type to choose among these

1)386
2)Opteron/Athlon64/Hammer/K8
3)Athlon/Duron/K7

One more doubt ... i've heard that we can choose 386 for any X86 based machine...

The specific architectures give only specialized instructions ... is it true?

thnks

Hi,
A 386 compiled kernel should work on all x86 compatible hardware, but does not make use of features and intructions not present in the 386. For optimal performance you should compile your kernel for the closest match to yours, which in this case is Athlon/Duron/K7. The Opteron/Athlon64/Hammer/K8 option is for 64 bit chips from AMD.

Regards,
Jimvin
