Hi,
what is "make dep" actually doing? What are those dependency files for. A
friend of mine insists on his opinion that it is enough to make bzImage
after reconfiguring the kernel. I always do a "make dep" after configuration
'cause it says to do so.
Regards,
Axel

Make dep (depend) means what it says, the process looks at what you have
choosen in your config file and then creates a file called .depend in each
source directory, .depend contains locations of header files called by each
option you choose.
Basicly thats it in a nutshell.
In fact your friend (like yourself) is correct, if you do not do 'make dep'
it will be done for you as make is told to check that it has been done in the
Makefile.
I belive its because long ago one "had" to type make dep, but thats long gone.

Question: Why I need to rebuild all the modules, if they are already builded.
https://wiki.ubuntu.com/KernelTeam/GitKernelBuild
If I make an one line change, I need to wait one hour to make an new
kernel on an intel core duo at 2GHz sistem ?

you *really* don't want to ask questions like this on LKML or the
ubuntu kernel list. ask again on the kernelnewbies list and we'll be
happy to explain it.

This is not an kernelnewbies qestion.
This in an Google project question.
Search for it.

make V=2 will tell you what file/config entry caused the rebuild to happen.

Depends on which file you change, if that is a header file,
it is supposed to re-compile all the C source files that include it.
Thanks.
