ACRN Hypervisor Service Module (HSM) is a kernel module in Service VM which communicates with ACRN userspace through ioctls and talks to ACRN Hypervisor through hypercalls. Add a basic HSM driver which allows Service VM userspace to communicate with ACRN. The following patches will add more ioctls, guest VM memory mapping caching, I/O request processing, ioeventfd and irqfd into this module. HSM exports a char device interface (/dev/acrn_hsm) to userspace.

The Freescale hypervisor management driver provides several services
|
|
to drivers and applications related to the Freescale hypervisor:
|
|
|
|
1) An ioctl interface for querying and managing partitions.
|
|
|
|
2) A file interface to reading incoming doorbells.
|
|
|
|
3) An interrupt handler for shutting down the partition upon
|
|
receiving the shutdown doorbell from a manager partition.
|
|
|
|
4) A kernel interface for receiving callbacks when a managed
|
|
partition shuts down.
