Re: [SLE] Kernel size?

Actually, I didn't compile them in, I turned off support. (at least that is what I understand answering "n" in menuconfig means. I did leave ide and floppy support compiled in, along with the ext2 and fat/vfat file systems. So it isn't a completely bare bones kernel. And yes, this is mostly just an academic exercise to see if it is possible to build a usable kernel with zImage, and try to answer the question, if not, why is the option still there?

If you build everything possible as modules and omit the things you don't have on your computer you should be able to get a 400 kb (-) kernel. Mine is 380,2 kb with support for various file-systems. When you say you turned off most of the modules I interpret that as that you actually built those features into the kernel. That's why you get a bigger kernel than the stock kernel. Regards

Just for fun I tried to build a kernel (from sources on the 6.2 CD) using make zImage. I paired the configuration down to what I felt was a bare minimum, leaving IDE, floppy, minimal networking, and basic file systems. I even turned off most of the modules. (I tried to turn off the multiple device support, but I got an unresolved reference error, and didn't have time to track it down, so I left that on.) But after all that, make errors out saying the kernel is too large and to do a make bzImage. Looking at the size of the resulting vmlinuz, it is almost twice as big as the copy in /boot. (the stock 6.2 image) What do I have to do to get a kernel that is "small enough?"

As I understand it, you are simply playing around now, and just trying to see if it is possible to make a very small kernel, right? (Otherwise, try 'make bzImage' instead of 'make zImage')

I managed to get the 6.1 kernel compiled with zImage. I think I left everything possible as modules, leaving only the ext2 filesystem inside the kernel.
