Dear all
Would you tell me the size of Linux 2.4.1 kernel? Is it very large?
Thanks a lot

It is between 20 and 30 meg to download.
It extracts to a very large source tree, over 100 meg.
When building, the object files take a lot of space.
A bootable kernel file can be less than a 1meg. A full blown working kernel
with all the modules compiled, can be about 15-20 meg in the
/lib/modules/2.4.xxx.

Size of the source tarball?
Check www.kernel.org, which size the latest source tarball has.
Size of a compiled kernel?
Depends on your setup/module use, I would suggest compiling one and check.
You may want to read the Kernel-HowTo available on www.linuxdoc.org.

Compressed, about 20 MBytes.
Kernel binary on my machines runs about 600kbytes.

However dmesg tells me the kernel occupies 878k of RAM -
Then there is the cumulative memory usage of the kernel modules -
# lsmod

The compressed archive is just over 20 MB:
-rw-rw-r-- 1 root root 20499361 Feb 21 17:00
linux-2.4.2.tar.bz2
However the directory it creates when uncompressed is much larger:
# du -sk linux
133632 linux
So the answer could be anywhere from 600k to 130 MB depending
on what you mean by "Linux" -

You obviously have a lot more code farmed out to modules than I do.
I use modules for sound, etc. but I like to keep my network card,
scsi drivers in the kernel itself.

1. Allow for profile_buf size = kernel text size
Hi
The following patch enables the kernel profiler to set up profiling
buffer equal to the kernel text size. It is particularly useful
while doing insn level profiling on archs with variable sized instructions.
There is a better possiblity of ticks being attributed to the right
instructions if the profiling granularity is better. Patch applies neatly on
2.5.43 and 2.5.43-mm2. Tested well on PIII 4way. Please apply.
