Apart from that, (probably both) configs need more stripping in the common
part. I want to have bootable (i.e. < 4 MiB) defconfig kernels.
Moreover, a compressed kernel fitting on a floppy would be better : there is
no USB port on this kind of machine, and the floppy is the easiest way to
boot a kernel.
Do you think it is possible ?
With a custom kerel, that should still be possible.
For a v3.12-rc6 mac_defconfig kernel, the figures are:
-rwxr-xr-x 1 geert geert 4873408 okt 20 11:31 /tmp/vmlinux*
-rwxr-xr-x 1 geert geert 2333743 okt 20 11:31 /tmp/vmlinux.gz*
-rwxr-xr-x 1 geert geert 2190667 okt 20 11:31 /tmp/vmlinux.bz2*
-rwxr-xr-x 1 geert geert 1802956 okt 20 11:31 /tmp/vmlinux.xz*
With some stripping, you should be able to fit (at least the xz version of)
the kernel on a floppy again.
(With 2.2 kernel we were able to put kernel AND ramdisk on the SAME floppy
!)
I know.
I even booted Linux with X and twm on an Amiga with 2 MiB chip RAM and
2 MiB Fast RAM (+ swap, of course). The uncompressed kernel fit
easily in 2 MiB.
