Gunyah is a Type-1 hypervisor independent of any high-level OS kernel, and runs in a higher CPU privilege level. It does not depend on any lower-privileged OS kernel/code for its core functionality. This increases its security and can support a much smaller trusted computing base than Type-2 hypervisors. This series adds the initial support for Gunyah hypercalls, IPC via message queues, communication with the Gunyah Resource Manager to enable Gunyah's paravirtualized console. Gunyah is an open source hypervisor. The source repo is available at https://github.com/quic/gunyah-hypervisor.
