GenieZone is MediaTek proprietary hypervisor solution, and it is running
in EL2 stand alone as a type-I hypervisor. It is a pure EL2
implementation which implies it does not rely any specific host VM, and
this behavior improves GenieZone's security as it limits its interface.

+======================
+GenieZone Introduction
+======================
+
+
+Overview
+========
+GenieZone is MediaTek proprietary hypervisor solution, and it is running in EL2
+stand alone as a type-I hypervisor. It is a pure EL2 implementation which
+implies it does not rely any specific host VM, and this behavior improves
+GenieZone's security as it limits its interface.
+
+To enable guest VMs running, a driver (gzvm) is provided for VMM (virtual
+machine monitor) to operate. Currently, the gzvm driver supports only crosvm.
+
+
+Supported Architecture
+======================
+GenieZone now only supports MediaTek arm64 SoC.
+
+
+Platform Virtualization
+=======================
+We leverages arm64's timer virtualization and gic virtualization for timer and
+interrupts controller.
+
+
+Device Virtualizaton
+====================
+We adopts VMM's virtio devices emulations by passing io trap to VMM, and virtio
+is a well-known and widely used virtual device implementation.

Plus, I'd expect documentation to be more detailed or have pointer
where
to learn more.

Sure, we tend to enumerate the high-level features of GenieZone and the
design considerations of each module on the next version of our
documentation.
