Hi friends i have installed linux kernel 3.16.3 version and kernel image found in "/boot/vmlinuz-3.16.3" size 5.9 mb it is possible to reduce the size of my current kerenl to 2 mb or less??

I have read this article : http://swift.siphos.be/linux_sea/kernelbuilding.html

But is there any straight forward way to do this?? Please help me out in this

Solution

Here are the steps

Do "make menuconfig" and disable all unused features
Inline functions increase the code size by copying the same code in multiple places.
- Remove "inline" flag to as many functions as possible.
Go to linker file and see any extra unused memory is allocated and remove them (vmlinux.lds.S in Arm codebase)
