Debugging kernel code line by line with Qemu and GDB
We are going to use buildroot to download, configure and compile the kernel.
First, download and uncompress buildroot: https://buildroot.org/download.html
Go to the directory and:
make qemu_x86_defconfig
make menuconfig

A C program consists of functions and variables. A function contains statements that specify the computing operations to be done,
and variables store values used during the computation.

SOLUTION - systemctl hangs and gives "Connection timed out" in every call when using serial-getty@.service
I've stumbled upon this problem after migrating from sysvinit to systemd.
To get the serial console working on systemd I had to set up a service called serial-getty@.service. It uses
agetty as a way to open ports, ask for login name and password.
The problem started after I noticed that my custom program, called with /sbin/agetty -i -n -l <program>, would not recognize the
Enter inserted as a End Of Line (EOL) special char. Then, I had to change from agetty to /bin/busybox getty to get the key recognized.
*latter I learned that this problem could be resolved using the command 'stty cooked'*

Add kernel parameters to your image
How do I change the Linux kernel command line?
The linux kernel command line is typically specified in the machine config using the APPEND variable. For example, you can add some
helpful debug information doing the following:
APPEND += "printk.time=y initcall_debug debug"
examples:
panic=N (if kernel panic happen, reboot after N seconds.)
