about upgrading the kernel.

[Halil Demirezen]

Hi folks,

I want to know, as the new patches and upgrades are published for the kernel, do i have to re-compile the 
whole kernel after i pached it? or is there any easy way of doing it so?


sincerely.

It depends on the patch and what compile options you have set. If ONLY 
module code is patched, you MIGHT get away with just recompiling the 
modules. But knowing that much about the patches themselves is not trivial, 
so the usual procedure is to do a complete kernel recompile.

As to "any easy way" ... what do you find difficult about doing a kernel 
compile? On my machines, it takes a lot of machine time, but only small bit 
of my time (after I do the first one, that is, which involves going through 
the config file, in my case with "make menuconfig", to select the options I 
want).

Compiling kernel a few times a day to see the effects of the new upgraded kernel is ok for me.
However, doing it 20 times a day is little difficult, isnt it?

never mind. I got the procedure each developer does in doing so.

Thank you.

Make (if the Makefile is correctly written) is quite clever to resolve any
depedencies and compile only the changed sources; as well as sources depend
on the changes.

This is done automagically. You just patch the sources and perform a 'make'.
OTOH, if you encounter strange bahaviour in the fresh kerenl, a 'make clean; 
make' won't hurt to try.
