 * The state transitions of ACRN I/O request:

 *
 * An I/O request in COMPLETE or FREE state is owned by the hypervisor. HSM and

 * request would look like:
 *

 * |
 * |   Service VM vCPU 0     Service VM vCPU x      User vCPU y
 * |

 * |                                               fills in type, addr, etc.
 * |                                               pauses the User VM vCPU y
 * |                                               sets the state to PENDING (a)
 * |                                               fires an upcall to Service VM
 * |
 * | HSM:
 * |  scans for PENDING requests
 * |  sets the states to PROCESSING (b)
 * |  assigns the requests to clients (c)
 * V
 * |                     client:
 * |                       scans for the assigned requests
 * |                       handles the requests (d)
 * |                     HSM:
 * |                       sets states to COMPLETE
 * |                       notifies the hypervisor
 * |
 * |                     hypervisor:
 * |                       resumes User VM vCPU y (e)
 * |
 * |                                             hypervisor:

 * V                                               sets states to FREE
 *
 * Note that the procedures (a) to (f) in the illustration above require to be
 * strictly processed in the order.  One vCPU cannot trigger another request of
 * I/O emulation before completing the previous one.
 *
 * Atomic and barriers are required when HSM and hypervisor accessing the state
 * of &struct acrn_io_request.
