# Linux Kernel Module Cheat

##### 38.10.1.1. disas

Since disassembly of a single function of a LKMC executable with GDB is such a common use case for run-toolchain via https://stackoverflow.com/questions/22769246/how-to-disassemble-one-single-function-using-objdump, we have this shortcut for it.

For example to disassemle a function from an userland binary:

    ./disas --arch aarch64 --userland userland/c/hello.c main

or to disassemble a function from the Linux kernel:

    ./disas --arch aarch64 start_kernel

and a baremetal executable:

    ./disas --arch aarch64 --baremetal baremetal/arch/aarch64/no_bootloader/exit.S _start
