Subject: [PATCH 00/11] Gunyah Hypervisor drivers

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.
