+Power Intel Uncore Test Plan
+============================
+Uncore is a term used by Intel to describe the functions of a microprocessor that are
+not in the core, but which must be closely connected to the core to achieve high performance;
+L3 cache, on-die memory controller, etc.
+L3fwd-power facilitates setting uncores frequency using DPDK Intel Uncore API.
+
+There is a test for each of the three options that are available for setting the uncore frequency,
+along with one final test to check successful exiting of Uncore API.
+
+Uncore is changed per socket level, this test suite is designed to change the uncore value 
+for each socket, however only socket 0 is verified to see if a change has been made.
+To view changed frequency, using MSR can be done on any core of the socket.
+See "Useful MSR 0x620 Information" section for more information.
+
+Preperation work
+================
+1. Check kernel version to make sure that it's greater than 5.6
+   uname -r
+2. Check if uncore is enabled.
+   cd /sys/devices/system/cpu/intel_uncore_frequency
+      if not:
+      check if kernel flag is enabled
+         cat /boot/config-$(uname -r) | grep -i "CONFIG_INTEL_UNCORE_FREQ_CONTROL"
+      Otherwise add uncore sysfs driver
+         modprobe intel-uncore-frequency
+3. Check if MSR driver is built-in or is loaded
+   modprobe msr
+
+Useful MSR 0x620 Information
+==========================
+* MSR 0x620 is a seperate register interface to configure uncore P-state ratio
+  limits and read back the current set uncore ratio limits.
+* Bits 0:6 are for max ratio and bits 8:14 for min ratio.
+* MSR 0x620 value is a ratio value, which means it must be multiplied by the base clock 
+  to get the uncore frequency in KHz. In this example 100000.
+* When reading MSR 0x620 during this test suite core 0 on socket 0 is only checked
+  for the uncore max and min ratio limits. When no core is specified for rdmsr,
+  then it defaults to core 0.
+
+Test Case 1: Validate_power_uncore_freq_max
+===========================================
+Step 1. Check current max set uncore frequency versus max possible frequency
+
+   "rdmsr 0x620 -f 6:0 -d" * 100000
+   cat /sys/devices/system/cpu/intel_uncore_frequency/package_00_die_00/initial_max_freq_khz
+
+   If these are equal, then change the value of each sysfs file by bringing them down 1 bin (100MHz).
+
+      echo {lower_uncore_max} > /sys/devices/system/cpu/intel_uncore_frequency/package_XX_die_XX/max_freq_khz
+
+Step 2. Run basic l3fwd-power configuration to set min/max uncore frequency to max limit
+
+   ./<build_target>/examples/dpdk-l3fwd-power -c 0x6 -n 1 -- -p 0x1 -P --config="(0,0,2)" -U
+
+Step 3. Confirm uncore min/max frequencies are set to max limit
+
+   "rdmsr 0x620 -f 6:0 -d" * 100000
+   "rdmsr 0x620 -f 14:8" * 100000
+
+
+Test Case 2: Validate_power_uncore_freq_min
+===========================================
+
+Step 1. Check current min set uncore frequency versus min possible frequency
+
+   "rdmsr 0x620 -f 14:8" * 100000
+   cat /sys/devices/system/cpu/intel_uncore_frequency/package_00_die_00/initial_min_freq_khz
+
+   If these are equal, then change the value of each sysfs file by bringing them up 1 bin (100MHz) .
+
+      echo {higher_uncore_min} > /sys/devices/system/cpu/intel_uncore_frequency/package_XX_die_XX/min_freq_khz
+
+Step 2. Run basic l3fwd-power configuration to set min/max uncore frequency to min limit
+
+   ./<build_target>/examples/dpdk-l3fwd-power -c 0x6 -n 1 -- -p 0x1 -P --config="(0,0,2)" -u
+
+Step 3. Confirm uncore min/max frequencies are set to min limit
+
+   "rdmsr 0x620 -f 14:8" * 100000
+   "rdmsr 0x620 -f 6:0 -d" * 100000
+
+
+Test Case 3: Validate_power_uncore_freq_idx
+===========================================
+
+Step 1. Check current max uncore frequency versus index 2.
+        Index 2 is equal to the frequency at index 2.
+        This is equal to => max possible freq - 200000(2 bin (200MHz)).
+        For example index range is [2400000, 2300000, 2200000,......,900000,800000], index 2 is 2200000.
+
+   "rdmsr 0x620 -f 6:0 -d" * 100000
+   (cat /sys/devices/system/cpu/intel_uncore_frequency/package_00_die_00/initial_max_freq_khz) - 200000
+
+   If these are equal, then change the value of each sysfs file by bringing them up 1 bin (100MHz).
+
+      echo {higher_uncore_idx} > /sys/devices/system/cpu/intel_uncore_frequency/package_XX_die_XX/max_freq_khz
+
+Step 2. Run basic l3fwd-power configuration to set min/max uncore frequency to index value
+
+   ./<build_target>/examples/dpdk-l3fwd-power -c 0x6 -n 1 -- -p 0x1 -P --config="(0,0,2)" -i 2
+
+Step 3. Confirm uncore min/max frequencies are set to index value
+
+   "rdmsr 0x620 -f 6:0 -d" * 100000
+   "rdmsr 0x620 -f 14:8" * 100000
+
+
+Test Case 4: Validate_power_uncore_exit
+=======================================
+
+Step 1. Run basic l3fwd-power configuration. Doesn't matter just want to get l3fwd-power running
+
+   ./<build_target>/examples/dpdk-l3fwd-power -c 0x6 -n 1 -- -p 0x1 -P --config="(0,0,2)" -U
+
+Step 2. Exit program and ensure there are no errors/ right output is recieved
+
+   Ctrl-C
+   Check for line "mode and been set back to the original"
+      Which should be the last line the program outputs when exiting correctly.
+      The start of the line is omitted as it won't be known which mode/which lcore will be set
+      back to the original.
