+===================================
+power bidirection channel test plan
+===================================
+
+preparation work
+================
+1. Turn on speedstep option in BIOS.
+2. Turn on CPU C3 and C6.
+3. Turn on turbo in BIOS.
+4. Disable intel_pstate in Linux kernel command ``intel_pstate=disable``.
+5. modprobe msr module to let the application can get the CPU HW info.
+6. Let user space can control the CPU frequency::
+
+ cpupower frequency-set -g userspace
+
+7. set a folder::
+
+ mkdir /tmp/powermonitor
+ chmod 777 /tmp/powermonitor
+
+
+Test Case 1 : Check VM can send power policy command to host and get acked
+==========================================================================
+Step 1. Launch VM using libvirt::
+
+ virsh start [VM name]
+
+Step 2. Launch VM power manager example on the host to monitor the channel from VM::
+
+ ./examples/vm_power_manager/build/vm_power_mgr -l 12-14 -n 4 --no-pci
+ vmpower> add_vm [vm name]
+ vmpower> add_channels [vm name] all
+ vmpower> set_channel_status [vm name] all enabled
+ vmpower> show_vm [vm name]
+
+ If VM name is ubuntu, the command as following:
+ vmpower> add_vm ubuntu
+ vmpower> add_channels ubuntu all
+ vmpower> set_channel_status ubuntu all enabled
+ vmpower> show_vm ubuntu
+
+Step 3. In the VM, launch guest_vm_power_mgr to set and send the power manager policy to the host power example::
+
+ ./examples/vm_power_manager/guest_cli/build/guest_vm_power_mgr -c 0xff -n 4 -m 1024 --no-pci --file-prefix=vm_power -- --vm-name=ubuntu --vcpu-list=0-7
+
+ Send command to the core 7 on host APP:
+ vmpower(guest)> set_cpu_freq 7 down
+
+ Check following info will be returned for the ACK activity, as following:
+ ACK received for message sent to host.
+
+ If command can't be executed, NACK will be returned, as following:
+ NACK received for message sent to host.
+
+Step 4. Set frequency on core which is out of the VM's core scope::
+
+ For example, the vcpu range is 0-7, we set command to vcpu number 9 as following:
+ vmpower(guest)> set_cpu_freq 9 down
+ GUEST_CHANNEL: Channel is not connected
+ Error sending message: Unknown error -1
+
+
+Test Case 2 : Query Host CPU frequency list from VM
+===================================================
+Step 1. Launch VM using libvirt::
+
+ virsh start [VM name]
+
+Step 2. Launch VM power manager example on the host to monitor the channel from VM::
+
+ ./examples/vm_power_manager/build/vm_power_mgr -l 12-14 -n 4 --no-pci
+ vmpower> add_vm [vm name]
+ vmpower> add_channels [vm name] all
+ vmpower> set_channel_status [vm name] all enabled
+ vmpower> show_vm [vm name]
+ vmpower> set_query <vm_name> <enable|disable>
+
+Step 3. Enable the query permission for target VM from host vm_power_mgr example::
+
+ Command format: set_query <vm_name> <enable|disable>
+ if vm name is ubuntu,command as following:
+ vmpower> set_query ubuntu enable
+
+Step 4. Query the CPU frequency for all CPU cores from VM side::
+
+ ./examples/vm_power_manager/guest_cli/build/guest_vm_power_mgr -c 0xff -n 4 -m 1024 --no-pci --file-prefix=vm_power -- --vm-name=ubuntu --vcpu-list=0-7
+ vmpower> query_cpu_freq <core_num> | all
+
+ Check vcpu 0~7 frequency info will be returned, for example:
+ Frequency of [0] vcore is 2300000.
+ Frequency of [1] vcore is 2200000.
+ Frequency of [2] vcore is 2800000.
+ Frequency of [3] vcore is 2300000.
+ Frequency of [4] vcore is 2300000.
+ Frequency of [5] vcore is 2300000.
+ Frequency of [6] vcore is 2300000.
+ Frequency of [7] vcore is 2300000.
+
+Step 5. Disable query permission from VM, check the host CPU frequency won't be returned::
+
+ at host side, disable query permission by vm_power_mgr example:
+ vmpower> set_query ubuntu disable
+
+ at VM side, query CPU frequency again, this action should not be executed successfully, log as following:
+ vmpower(guest)> query_cpu_freq all
+ GUEST_CLI: Error receiving message.
+ Error during frequency list reception.
+
+
+Test Case 3: Query CPU capability from VM
+=========================================
+Step1~3. The same as test case 2
+
+Step4: Query all the valid CPU core capability of host, check all cores' information is returned. Check the high priority core is recognized correctly::
+
+ For example, core 2 is returned as high priority core:
+ vmpower(guest)> query_cpu_caps all
+ Capabilities of [0] vcore are: turbo possibility: 1, is priority core: 0.
+ Capabilities of [1] vcore are: turbo possibility: 1, is priority core: 0.
+ Capabilities of [2] vcore are: turbo possibility: 1, is priority core: 1.
+ Capabilities of [3] vcore are: turbo possibility: 1, is priority core: 0.
+ Capabilities of [4] vcore are: turbo possibility: 1, is priority core: 0.
+ Capabilities of [5] vcore are: turbo possibility: 1, is priority core: 0.
+ Capabilities of [6] vcore are: turbo possibility: 1, is priority core: 0.
+ Capabilities of [7] vcore are: turbo possibility: 1, is priority core: 0.
+
+Step 5: Query CPU capability for core out of scope, check no CPU info will be return::
+
+ For example, the valid vcpu range is 0~7, query cpu capability of core 9 should return error as following:
+ vmpower(guest)> query_cpu_caps 9
+ Invalid parameter provided.
+
+Step 6: Disable query permission from VM, check the host CPU capability won't be returned::
+
+ at host side, disable query permission by vm_power_mgr example:
+ vmpower> set_query ubuntu disable
+
+ at VM side, query CPU capability again, this action should not be executed successfully, log as following:
+ vmpower(guest)> query_cpu_caps all
+ GUEST_CLI: Error receiving message.
+ Error during capabilities reception.
