The experimental empty poll API has been removed from the power
management library in DPDK 22.03. Removing test_plan, power_empty_poll
test has already been removed.

-Inband Policy Control
-=====================
-
-For packet processing workloads such as DPDK polling is continuous. This means
-CPU cores always show 100% busy independent of how much work those cores are
-doing. It is critical to accurately determine how busy a core is hugely
-important for the following reasons:
-
-   * No indication of overload conditions
-
-   * User do not know how much real load is on a system meaning resulted in
-     wasted energy as no power management is utilized
-
-Tried and failed schemes include calculating the cycles required from the load
-on the core, in other words the busyness. For example, how many cycles it costs
-to handle each packet and determining the frequency cost per core. Due to the
-varying nature of traffic, types of frames and cost in cycles to process, this
-mechanism becomes complex quickly where a simple scheme is required to solve
-the problems.
-
-For all polling mechanism, the proposed solution focus on how many times empty
-poll executed instead of calculating how many cycles it cost to handle each
-packet. The less empty poll number means current core is busy with processing
-workload, therefore,  the higher frequency is needed. The high empty poll
-number indicate current core has lots spare time, therefore, we can lower the
-frequency.
-
-2.1 Power state definition:
-
-LOW:  the frequency is used for purge mode.
-
-MED:  the frequency is used to process modest traffic workload.
-
-HIGH: the frequency is used to process busy traffic workload.
-
-2.2 There are two phases to establish the power management system:
-
-a.Initialization/Training phase. There is no traffic pass-through, the system
-will test average empty poll numbers  with LOW/MED/HIGH  power state. Those
-average empty poll numbers will be the baseline for the normal phase. The
-system will collect all core's counter every 100ms. The Training phase will
-take 5 seconds.
-
-b.Normal phase. When the real traffic pass-though, the system will compare
-run-time empty poll moving average value with base line then make decision to
-move to HIGH power state of MED  power state. The system will collect all
-core's counter every 10ms.
-
-``training_flag`` : optional, enable/disable training mode. Default value is 0.
- If the training_flag is set as 1(true), then the application will start in
- training mode and print out the trained threshold values. If the training_flag
- is set as 0(false), the application will start in normal mode, and will use
- either the default thresholds or those supplied on the command line. The
- trained threshold values are specific to the user’s system, may give a better
- power profile when compared to the default threshold values.
-
-``med_threshold`` : optional, sets the empty poll threshold of a modestly busy
-system state. If this is not supplied, the application will apply the default
-value of 350000.
-
-``high_threshold`` : optional, sets the empty poll threshold of a busy system
-state. If this is not supplied, the application will apply the default value of
-580000.

-Preparation Work for Settings
-=============================
-BIOS setting::
-
-    1. Turn on Speedstep option in BIOS
-    2. Turn on Turbo in BIOS
-    3. Turn off Hyper Threading
-
-Linux setting::
-
-    1. Use intel_pstate driver for CPU frequency control
-    2. modprobe msr
-
-sys_min=/sys/devices/system/cpu/cpu{}/cpufreq/cpuinfo_min_freq
-sys_max=/sys/devices/system/cpu/cpu{}/cpufreq/cpuinfo_max_freq
-no_turbo_max=$(rdmsr -p 1 0x0CE -f 15:8 -d)00000
-
-cur_min=/sys/devices/system/cpu/cpu{}/cpufreq/scaling_min_freq
-cur_max=/sys/devices/system/cpu/cpu{}/cpufreq/scaling_max_freq
-
-
-Test Case1 : Basic Training mode test based on one NIC with l3fwd-power
-=======================================================================
-Step 1. Bind One NIC to DPDK driver, launch l3fwd-power with empty-poll enabled
-
-    ./<build_target>/examples/dpdk-l3fwd-power -l 1-2 -n 4 -- -p 0x1 -P --config="(0,0,2)" --empty-poll="1,0,0" -l 10 -m 6 -h 1
-
-Step 2. Check the log also when changing the inject packet rate as following:
-
-    Injected Rate(1024B, dst_ip=1.1.1.1): 10G -> 0.1G -> 10G -> 0.1G -> 10G ->
-    0.1G The frequency will be set to MED when we inject 0.1G and return to HGH
-    when inject 10G Rate, check the frequency of the forwarding core(core 2)
-    When traffic is 10G:  cur_min=cur_max=no_turbo_max
-    When traffic is 0.1G: cur_min=cur_max=[no_turbo_max-500000]
-
-
-Test Case2: No-Training mode test based on one NIC with l3fwd-power
-===================================================================
-Step 1. Bind One NIC to DPDK driver, launch l3fwd-power with empty-poll enabled
-
-   ./<build_target>/examples/dpdk-l3fwd-power -l 1-2 -n 4  -- -p 0x1 -P --config="(0,0,2)" --empty-poll="0,350000,500000" -l 10 -m 6 -h 1
-
-Step 2. Check no training steps are executed in sample's launch log.
