-Power managerment throughput test plan
-======================================
-
-This test plan test cpu frequence changed according io workloads with l3fwd-power sample.
-The cpu frequency status depends on NIC and CPU type.
-
-Prerequisites
-=============
-
-1. Update Grub::
-
-    Add "intel_pstate=disable" in kernel options.
-
-2. BIOS configuration as below::
-
-    CPU mode : "Power"
-    Workload configuratuion："IO sensitive"
-    Hardware Power : "Disabled"
-    Speedstep : "Enabled"
-    Turbo : "Enabled"
-    C-stats：C0/C1
-    C6 : "Enabled"
-
-Test Case1: Check the CPU frequency can change according differernt packet speed
-================================================================================
-
-1. Check that you are using the "acpi-cpufreq" driver by command "cpufreq-info".
-
-2. CPU frequency controlled by userspace by command "cpupower frequency-set -g userspace".
-
-3. Bind one nic port to igb_uio, launch l3fwd-power sample, one core used for one port::
-
-    ./<build_target>/examples/dpdk-l3fwd-power -c 0xc000000 -n 4 -- -P -p 0x01  --config '(0,0,27)'
-
-4. Send packets by packet generator with high speed, check the used cpu frequency is almost 100%::
-
-    cat /sys/devices/system/cpu/cpu27/cpufreq/cpuinfo_cur_freq
-
-5. Send packets by packet generator with low speed, the CPU frequency will reduce about 50%::
-
-    cat /sys/devices/system/cpu/cpu27/cpufreq/cpuinfo_cur_freq

+The cpu frequency status depends on traffic speed.

+
+3. Let user space can control the CPU frequency::
+
+    cpupower frequency-set -g userspace
+
+Test Case 1: Check the CPU frequency with high traffic speed
+================================================================================
+
+1. Bind one nic port to igb_uio, launch l3fwd-power sample with sacle mode, one core used for one port::
+
+    ./<build_target>/examples/dpdk-l3fwd-power -c 0x6 -n 1 -- --pmd-mgmt scale --max-empty-poll 128 -p 0x1 -P --config="(0,0,2)"
+
+2. Send packets by packet generator with high speed, check the cpu frequency it should be equal or below turbo max frequency
+   and be higher than p1.
+
+    cat /sys/devices/system/cpu/cpu2/cpufreq/cpuinfo_cur_freq
+
+Test Case 2: Check the CPU frequency with low traffic speed
+================================================================================
+
+1. same as Test Case 1 step 1.
+
+2. Send packets by packet generator with low speed, check the cpu frequency it should be below p1.
