6 The ACRN Hypervisor is a Type 1 hypervisor, ru
7 hardware. It has a privileged management VM, c
8 VMs and do I/O emulation.

10 ACRN userspace is an application running in th
11 devices for a User VM based on command line co
12 Service Module (HSM) is a kernel module in the
13 hypervisor services to the ACRN userspace.

35 ACRN userspace allocates memory for the User V
36 devices used by the User VM, loads the virtual
37 virtual CPU state and handles I/O request acce
38 ioctls to communicate with the HSM. HSM implem
39 interacting with the ACRN Hypervisor via hyper
40 interface (/dev/acrn_hsm) to userspace.
