Looking for the list of config options used for the kernel
 

I'm trying to track down the cause of an ACPI-related (I think, anyway) problem and I'm looking for the kernel configuration options that were used to build the Leap 15.1 kernels. I seem to remember that these were included when you installed the OS but I'm drawing a blank as to where it might be saved on disk. I thought they'd be somewhere under /usr/src/linux but so far my searching hasn't found anything. (I should note that I might very well be remembering that such a file was included back when I was using an entirely different Linux distribution.)

Does Leap include such a file with the list of options selected for the kernel build? If so, where should I find it?

TIA...

Documentation/admin-guide/kernel-parameters

Normally, don't know about Leap specificaly, its the config, or config-<some_version> file in the /boot directory (where the kernel itself is too, unless you're using EFI).

And if that's not there, have a look for /proc/config.gz

That tells me what I can add to or modify on the grub command line. I'm looking for the options that were selected during the execution of, say, "menuconfig" prior to compiling the kernel.

Ah ha! That's what I'm looking for. I remember this being saved in the source code tree (but that was a long time ago).

The files under /boot seem to have the same information. Not sure how I missed that before.

Thanks everyone.

Whoops! sorry. /usr/src/linux/.config . I keep an archive of all my configs, useful to keep track of changes. I edit it by hand sometimes.

That's the place for Slackware. openSUSE didn't, for some reason, choose to follow that convention. Definitely threw me. :^D

I build my own kernels.

As did I back when Slackware was my main distribution.

Later...
