| The Gunyah drivers are the helper interfaces that run in a guest VM |
| such as basic inter-VM IPC and signaling mechanisms, and higher level |
| services such as memory/device sharing, IRQ sharing, and so on. |

| Enable kernel support for host-scheduled vCPUs running under Gunyah. |

| can schedule the guest VM's vCPUs instead of using Gunyah's scheduler. |
| VMMs can also handle stage 2 faults of the vCPUs. |
