# LinuxKernelDevelopment_Playground
This repo contains 2 simple projects related to kernel development: a kernel module that prints stuff and a character device driver that also prints stuff but repeatedly!
This was done on a machine running Ubuntu 20.04 with kernel version `5.15.0`. Some functions/macros may differ depending in the kernel version you are running so feel free to check [Bootlin's Website](https://elixir.bootlin.com/linux/v5.15/source/kernel) to know more about the right syntax.
## Preparations
1. In order to check for kernel version, run:
```
uname -r
```
1. Install essentials for kernel development:
```
sudo apt install build-essential linux-headers-$(uname -r)
```
## Loading & Unloading Modules
```
# for loading
sudo insmod hello.ko
# for unloading
sudo rmmod hello.ko
```
## Bro Tip
If you forgot your root password for some reason, using a user account that has root privilages, run:
```
sudo passwd root
```
