Subject: [RFC PATCH 00/15] acrn: add the ACRN driver module
ACRN is a flexible, lightweight reference hypervisor, built with real-time
and safety-criticality in mind, optimized to streamline embedded development
through an open source platform. It is built for embedded IOT with small
footprint and real-time features. More details can be found
in https://projectacrn.org/
This is the patch set that add the ACRN driver module on ACRN guest, which
acts as the router to communciate with ACRN hypervisor.
The user-space applications can use the provided ACRN ioctls to
interact with ACRN hypervisor through different hypercalls. After the ACRN
module is loaded, the device file of /dev/acrn_hsm can be accessed in
user-space. It includes the management of virtualized CPU/memory/
device/interrupt/MMIO emulation for other ACRN guest.
The first three patches are the changes under x86/acrn, which adds the
required APIs for the driver and reports the X2APIC caps.
The remaining patches add the ACRN driver module, which accepts the ioctl
from user-space and then communicate with the low-level ACRN hypervisor
by using hypercall.
