Does Linux really support AMD K7?

[philippis]

In the README shipped with 2.4.x kernels, the great kernel guys suggest egcs 2.91.
I followed this instruction and compiled kernel with Athlon/Duron/K7 selected. Howver,
it seems that the kernel was compiled with -march=i686 option. In fact, egcs 2.91 does
not accept -march=athlon at all. If you compile gcc 2.95 or higher compile the kernel
with Athlon/Duron/K7 selected, the bootup procedure will hang up.

The bottom question is "Does Linux really support AMD K7?

Firstly, I know you need to use gcc 3.X to be able to use -march=athlon.

Secondly I have a Tbird 900 and I always choose Athlon when compiling my kernel and it works fine, you probably have another problem.

Is this what you're thinking of?????

Yes it does.....

I've used and compiled Linux Kernels on countless Athlon Systems all cores....

its the compiler which matters. Linux works fine with K7's. depending on your versions of gcc/egcs, it will decide whether or not you can use -march=athlon.

I've used Mandrake 8.0, RedHat 7.1 and RedHat 7.2 with my T-Bird. Never had an issue.

I don't think he's really asking whether or not it will work at all; he seems to be asking if the kernel can be compiled with Athlon optimizations. Specifically I don't know (though I'd trust Nothinman's answer since he's usually got his info straight), but there is definately an Althon option I always select and my linux system works fine with that option selected (powered by a Duron 750).

I run RedHat 7.2 and I've compiled my kernel for Athlon optimizations, but I do notice the output of the uname -mp command is "i686 unknown". I have gcc 2.96 installed. So I guess you're not the only one with this question.
