+=============================
+Power Lib Telemetry Test Plan
+=============================
+
+Three types of data will be reported by DPDK telemetry lib in l3fwd-power sample.
++ {"empty_poll"},
++ {"full_poll"},
++ {"busy_percent"}
+
+
+Preparation Work for Settings
+=============================
+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. Let user space can control the CPU frequency::
+
+ cpupower frequency-set -g userspace
+
+Compile DPDK with telemetry enabled, enable telemetry lib in configuration file::
+
+ -CONFIG_RTE_LIBRTE_TELEMETRY=n
+ +CONFIG_RTE_LIBRTE_TELEMETRY=y
+
+
+Test Case 1 : Check all 3 type of power related info reported by Telemetry System
+=================================================================================
+1. Launch l3fwd-power sample with telemetry enabled, bind one NIC to DPDK driver, launch l3fwd-power::
+
+ ./l3fwd-power -l 1-2 -n 4 --telemetry -- -p 0x1 -P --config="(0,0,2)" --telemetry
+
+2. Get the telemetry info using dpdk-telemetry-client.py script, then choose mode 3 ``Send for global Metrics``::
+
+ python usertools/dpdk-telemetry-client.py /var/run/some_client
+
+3. Check the returned info include "empty_poll", "full_poll", "busy_percent", as following::
+
+ {
+ "port": 4294967295,
+ "stats": [
+ {
+ "name": "empty_poll",
+ "value": 1705624132
+ },
+ {
+ "name": "full_poll",
+ "value": 4275898
+ },
+ {
+ "name": "busy_percent",
+ "value": 0
+ }]
+ }
+
+Test Case 2 : Check busy_percent with different injected throughput
+===================================================================
+1. Using step1~3 in test case 1.
+
+2. Inject packets with line rate with 64 bit frame size, check the busy_percent returned, it should be no-zero number.
+
+3. Stop the injected packet stream, check the busy_percent returned, it should be 0.
