      <description>Today, we will be learning about exception levels.(have patience, we&amp;rsquo;ll write actual code too, but in the next post.) Exceptions levels define execution privilege at each level. There are 4 exception levels in ARMv8 architecture.
 Exception Level 0 (EL0): This Exception Level or Privilege Level is commonly used by userspace applications. Firefox, Libreoffice, VLC Media Player, and VirtualBox are a few examples of userspace applications. Exception Level 1 (EL1): Kernel and all privileged code associated with kernel works in EL1 execution level.</description>

      <description>This is a series of tutorials that I never had a year ago when I decided to write a bare-metal hypervisor on Raspberry Pi 4, Leo Hypervisor. I did not have prior experience with bare-metal or even kernel development. Therefore, I will be sharing all that I have learned in the following series of tutorials. You are welcome to contribute to this project and I would also love to learn from you.</description>
