A feature allows workload to deliver policy to the host to manage power controls 
such as p-states extends the thinking of the current scheme moving away 
from direct controls to policy controls to avoid latency & jitter 
penalties. Also provides the ability to react faster. 

v4: 
 -  remove support architecture description. 
 -  

v3: 
 -  change turbo command execution result check condition. 
 -  rebase source code. 
 -  

v2: 
 -  use new pktgen methods as traffic policy mode testing packet generator. 
 -  abandon non-blocked ixia traffic source code changes in framework. 
 -  add query script methods to take the place of non-blocked query method. 
 -  use cpu turbo status query script method to take the place of local api call. 
 -  change all functional test cases to performance test cases to be easier to deploy in one execution config. 
 -  add power driver type check method. 
 -  add cpupower tool existence check method. 
 -  optimize cpu scaling_max_freq/scaling_available_frequencies/scaling_min_freq query time consumption. 
 -  add cpu frequency preset method to clear previous testing influence. 
 -  add vf passthrough to vm to do traffic policy testing.

A feature allows workload to deliver policy to the host to manage power controls
such as p-states extends the thinking of the current scheme moving away
from direct controls to policy controls to avoid latency & jitter
penalties. Also provides the ability to react faster.

VM Power Manager would use a hint based mechanism by which a VM can
communicate to a host based governor about its current processing
requirements. By mapping VMs virtual CPUs to physical CPUs the Power Manager
can then make decisions according to some policy as to what power state the
physical CPUs can transition to.

VM Agent shall have the ability to send the following policy to host.
- traffic policy
- time policy

VM Agent shall have the ability to send the following hints to host::
- core disable turbo
- core enable turbo

+
+
+Test Case : time policy
+=======================
+check these content.
+#. when dut clock is set to a desired busy hours, put core to max freq.
+#. when dut clock is set to a desired quiet hours, put core to min freq.
+
+This case test multiple guest_vm_power_mgr options, they are composited
+by these content as below::
+
+    #. --policy
+       TIME
+    #. --vm-name
+      vm0
+    #. --vcpu-list
+      0
+      0,1,2,3,4,5,6,7

+      23
+      0-23
+      4,5-7,23
+
+example::
+
+    --vm-name=vm0 --policy=TIME --vcpu-list=0,1,2,3,4,5,6,7 --busy-hours=0-23,5-7,23
+
+steps:
+
+#. set DUT system time to desired time.
+
+#. set up testing environment refer to ``Set up testing environment`` steps.
+
+#. trigger policy on vm DUT from guest_vm_power_mgr console::
+
+    vmpower(guest)> send_policy now
+
+#. check DUT platform cores frequency, which are in vcpu-list.
+
+
+Test Case : traffic policy
+==========================
+check these content.
+#. use packet generator to send a stream with a pps rate bigger 2000000,
+vcpu frequency will run at max frequency.
+#. use packet generator to send a stream with a pps rate between 1800000 and 2000000,
+vcpus frequency will run at med frequency.
+#. use packet generator to send a stream with a pps rate less than 1800000,
+vcpu frequency will run at min frequency.
+
+This case test multiple guest_vm_power_mgr options, they are composited
+by these content as below::
+
+    #. --policy
+       TRAFFIC
+    #. --vm-name
+      vm0
+    #. --vcpu-list
+      0
+      0,1,2,3,4,5,6,7
+
+example::
+
+    --vm-name=vm0 --policy=TRAFFIC --vcpu-list=0,1,2,3,4,5,6,7
+
+steps:
+
+#. set up testing environment refer to ``Set up testing environment`` steps.
+
+#. trigger policy on vm DUT from guest_vm_power_mgr console::
+
+    vmpower(guest)> send_policy now
+
+#. configure stream in traffic generator, set traffic generator line rate
+   to desired pps and send packet continuously.
+
+#. check DUT platform cores frequency, which are in vcpu-list.
+
+
+Test Case : disable CPU turbo
+=============================
+check a custom cpu turbo status can be disable.
+
+steps:
+
+#. set up testing environment refer to ``Set up testing environment`` steps.
+
+#. set cpu turbo disable on vm DUT from guest_vm_power_mgr console::
+
+    vmpower(guest)> set_cpu_freq <core_num> disable_turbo
+
+#. verify the DUT physical CPU's turbo has been disable correctly, core frequency
+   should be secondary max value in scaling_available_frequencies::
+
+    cat /sys/devices/system/cpu/cpu1/cpufreq/cpuinfo_cur_freq
+    cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_available_frequencies
+
+Test Case : enable CPU turbo
+============================
+check a custom cpu turbo status can be enable.
+
+steps:
+
+#. set up testing environment refer to ``Set up testing environment`` steps.
+
+#. set cpu turbo enable on vm DUT from guest_vm_power_mgr console::
+
+    vmpower(guest)> set_cpu_freq <vm_core_num> enable_turbo
