[PATCH v1 0/6] GenieZone hypervisor drivers

From: Yi-De Wu
Date: Thu Apr 13 2023 - 05:08:21 EST


This series is based on linux-next, tag: next-20230412.

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.

This series supports ioctl interfaces for userspace VMM(eg., crosvm) to
operate guest VMs lifecycle, irqchip for virtual interrupt handling,
asynchronous notifcation mechanism for VMM.
