Kernel compilation

[Szymon Wilczyński]

Hi,

I'd like to compile kernel optimized for athlon. Currently my box runs
2.4.22-1.2110.
My goal is to compile the same kernel (identical config) but optimized for
athlon.
1. There are some default configs, but are they the same as for the
precompiled kernel?
2. Is it enough to run make config, check the procesor architecture for
athlon settings and quit?
3. If so - finally how to produce initrd image?

Thanks
Szymon

Good luck, I am in the same boat, odds are the it will fail building on
something. You can get their, but in my case it typically involved
ripping out support I didn't need anyway. The default config is a good
starting point and you may get lucky and it will build, but I am willing
to wager that something will fail when  you do a make modules :-)

mkinitrd is what you build the initrd image.
I avoid this by not using modules for anything I need on boot anyway.

In my case I don't think I would ever be unloading my scsi driver or
ext3 anyway :-)

We already include an Athlon optimized kernel.

there are config files for from installed kernel packages in /boot. 
i.e., something like /boot/config-2.4.22-1.2110.  Copy that to your
.config in your source directory, *then* change processor (and anythign
else you want to change).

Also make sure you're using the Red Hat sources, not stock sources, or
you may end up with some problems.

I must have been blind. Yes indeed the kernel I'm running is optimized
for athlon.
Thanks to the others for hints.
