Backend service access the native HECI driver through MEI driver
interface in service OS. Some MEI clients need to be multiplexed,
the backend service will engage necessary service at clients filter.
TX thread is for passing data from guest to host MEI driver, then to
native hardware. RX thread is for passing data from native hardware to
guest.

This patch implement HECI virtualization backend service based on virtio
userspace framework. This service introduce a virtio-heci device model
for DM, and can be enabled by DM parameter '-s [BUS NO],virtio-heci'.
The HECI virtualization need both backend service in device-model and
frontend driver in guest to work. Backend service mainly emulates HECI
device's behaviors to satisfy frontend driver. They are based on virtio
userspace framework. Currently, it is using two virtqueues, one is for
TX and another is for RX.

Per trusty design, trusty requires a monotonic increasing
secure tick(TSC) at run time. This secure tick will used
to mitigate password/pin force attack, control key expiration,

Currently, the TSC_OFFSET is enabled. And guest will got
(host_tsc + tsc_offset) when execute rdtsc/rdtscp/rdmsr to
aquire tsc value. The host_tsc is always keeping increasing
during the runtime.
So initialize tsc_offset of trusty to 0 will ensure the

not blindly passthrough perf_ctrl MSR to guest. Instead guest access
is always trapped and validated by acrn hypervisor before forwarding

The acrnctl can help user to create, delete, launch and stop UOSs,
To see what it can do, just run:
# acrnctl
or
# acrnctl help
you may see:
support:
list
start
stop
del
add
Use acrnctl [cmd] help for details
There are examples:
(1) add a VM
Each time you can just add one VM. Suppose you have an UOS
launch script, such as launch_UOS.sh
you can run:
# acrnctl add launch_UOS.sh -U 1
vm1-14:59:30 added
Note that, launch script shoud be able to launch ONE UOS. If
it fail, it is better to print some error logs, to tell user
the reason, so that he knows how to solve it.
The vmname is important, the acrnctl searchs VMs by their
names. so duplicated VM names are not allowed. Beside, if the
launch script changes VM name at launch time, acrnctl will
not recgonize it.
(2) delete VMs
# acrnctl del vm1-14:59:30
(3) show VMs
# acrnctl list
vm1-14:59:30 untracked
vm-yocto stop
vm-android stop
(4) start VM
you can start a vm with 'stop' status, each time can start
one VM.
# acrnctl start vm-yocto
(5) stop VM
you can stop VMs, if their status is not 'stop'
# acrnctl stop vm-yocto vm1-14:59:30 vm-android
