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 hints to host:
- Scale frequency down
- Scale frequency up
- Reduce frequency to min
- Increase frequency to max

+===================
+VM Power Management
+===================
+
+This test plan is for the test and validation of feature VM Power Management
+of DPDK 1.8.
+
+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 hints to host:
+- Scale frequency down
+- Scale frequency up
+- Reduce frequency to min
+- Increase frequency to max
+
+The Power manager is responsible for enabling the Linux userspace power
+governor and interacting via its sysfs entries to get/set frequencies.
+
+The power manager will manage the file handles for each core(<n>) below:
+- /sys/devices/system/cpu/cpu<n>/cpufreq/scaling_governor
+- /sys/devices/system/cpu/cpu<n>/cpufreq/scaling_available_frequencies
+- /sys/devices/system/cpu/cpu<n>/cpufreq/scaling_cur_freq
+- /sys/devices/system/cpu/cpu<n>/cpufreq/scaling_setspeed
+

+
+3. OS and Kernel:
+ - Fedora 20
