registers

registers is a simple linux kernel module (LKM) which creates /proc/registers, a kernel proc file which holds the contents of eax, ebx, ecx, edx (x86 general purpose registers). Pretty useless as they change during execution but a good way to start LKM coding and try out some inline assembler.

Build

Build with:

make

Usage

Insert into kernel:

sudo insmod registers.ko

Then type dmesg or lsmod | grep registers to see if the module got loaded.

To view the register contents, use

cat /proc/registers

To unload the module, use:

sudo rmmod registers
