    27 This consists in reviewing RTEMS code and indentify which part of the code requires privileged instructions. After these code review efforts, the goal of this first activity would be used to design an architecture-agnostic API to perform privileged instructions. Basically, these instructions would be adapted when RTEMS is running as a guest OS, making hypercalls to the hypervisor layer.

After these code review efforts, the goal of this first activity would be used to design an architecture-agnostic API to execute privileged instructions. Basically privileged instructions would be wrapped so that when RTEMS is running as a guest OS it will instead make hypercalls to the hypervisor layer.
