Upgrading the kernel

Jorek · 09-13-2010, 02:08 PM

Hi there!
I'm about to upgrade the kernel to the latest stable version, and I am wondering if I could just use the .config file found on the ftp mirrors under /Slackware-13.01/kernels/hugesmp when compiling?

I mean, instead of doing it manually using menuconfig.

Cheers!

You can use that config if you like, just run make oldconfig first.

I'd use config-generic-smp as a starting point instead of config-huge-smp though,

just configure the file system you use for the 'root' partition as built-in, and you shouldn't need an initrd.

Edit:
Robby Workman recently posted some config files for 2.6.35.x:

Robby has posted a generic config file for 2.6.35.4 for Slackware. x86
x86-64. It will be easier than having to answer all the default questions due to changes in the kernel versions from 2.6.33. But to answer the question I would normally do

Code:

make oldconfig

at the very least. Google "alien kernel" for Eric's Slackware kernel how-to.

Thanks guys!

Great links by the way!

I usually use the generic-smp kernel's config and do:

Code:

yes '' | make oldconfig

Which updates the config file and automatically chooses the defaults for all new options.

But since Robby has generic configs for the latest kernel, you might as well use those.

Hi,

Building a Linux Kernel from source Eric Hameleers (Alien’s) Wiki pages.

I really dig that guide, onebuck!
I recommend it to all first-time-kernel-compilers! =) Great read!

It's more up to date than the Slackware Essentials 2'nd edition!

Does this actually pipe yes to all the questions? Doesn't that say yes to a lot of defaults that would otherwise be no, and that might very possibly interfere since they are being built INTO the kernel rather than as modules? I generally would do

Code:

make oldconfig

and then just hold down enter to choose the default answer for each new option which is generally "no" and then I do my in-depth checking of new options in menu/gconfig.

The yes command "repeatedly outputs a line with all specified STRING(s), or `y'"

Since the string I specified was '', it does the same thing as leaving the answer blank and pressing enter, just much faster.

Ah. Very nice.
