Recompiling the linux Kernel after patching
 

Hello All,

I am doing some development work which very often includes editing some Linux kernel files. After making these changes, i am required to re-compile the kernel for the changes to take effect in the kernel after restart. Most of the times, the changed files are of driver/pci/ directory.

For re-compiling the kernel, I do following steps.

make clean
make bzImage
make install


Are these steps enough for the made changes to take effect properly ?

Normally compiling the new kernel along with its modules takes following steps

make clean
make modules
make modules_install
make bzImage
make install


But make modules and the step after that takes a long time and besides as per my understanding they are for compiling the modules. As in my case, the core kernel code is changing, do I need to issue these two commands as well???

Can you suggest some steps which I am missing here.

Thanks.

I'd suggest that the way to make your rebuilds faster is to not do the "make clean". However, for this to work the Makefiles need to "good".
