kernel config repository

kernel config repository

[Eric Persson]

Hi,

I hope I'm not totally wrong here, but I figured this would be a good 
place to start, the kernel-config list seems a bit dead.

I've been thinking about creating a community-driven .config repository, 
since I havent found any good place for this sort of information.
I would see it as a place for people to contribute .configs for various 
hardware/platforms and keep them updated and current with the kernel 
releases.

Perhaps this exist(i havent found any easily), or is considered a bad 
idea(please tell me), or is actually a good idea.

Tell me what you think, sorry if I might have sent this to the wrong list.

Keep up the good work.

Best regards,
    Eric

Eric,

For ppc and ppc64, there are some config files:
arch/ppc/configs/ and arch/powerpc/configs/.

Seems none for i386.

For some users being able to grab a pre-made .config may be valuable,
but for most people I doubt it will be very useful. Peoples hardware
differ a lot, so a "best" config is always going to be one that you
tweak personally to match your system. If you don't want to do that
you are probably just going to use a generic distro kernel anyway (or
you could use the .config of the distro kernel with make oldconfig
when building a new kernel).

Maybe it's a good idea, dunno, but I don't really think so.

Yes, I save the configs for every kernel that I install, so I could
post those, but I don't see the usefulness of this idea.

I understand your point, and you might as well be right.

I have experienced a very tough testing phase to make myself believe and 
thrust a new kernel config, before I put it to live use. I only use HP 
machines, most of them the same model and the difference in hardware are 
usually just disks, memory and speed of cpu, which affects the config 
inself very minmial, otherwise theyre all the same.
And to hook up and see other HP(replace with any brand/model) users and 
see what configs they use, so all can benefit from config testing, would 
be a great idea, thats what I think at least.

People compiling custom kernels for whatever piece of hardware they can 
find will most likely not benefit, but the overall "community wisdom" 
that this might generate would perhaps everyone benefit from.

Today, I find it hard find information about all the different configs, 
more than whats in the help function in make menuconfig, but thats me. 
And I think its a waste if good kernel development get ignored since 
people dont know what config options to turn on. ;)

Well, I hope I might inspired or given some clarity on the topic, any 
new input from this?

Best regards,
	Eric

Even excluding the case that many computers are more or less unique 
combinations of half a dozen different components, everyone will use 
different settings for most hardware-independent things like e.g. file 
systems, preemption or networking options. Even if I had the same 
hardware as you have, my config settings would therefore most likely be 
completely different from yours.

The help texts for the config options should be enough for an 
experienced system administrator to set the right options.

If you know about help texts that could be improved, patches to improve 
them are welcome.
