+===============
+memory register
+===============
+
+It is a way to register memory outside hugepages with DPDK after start up.
+Specifically, the registered memory will be the target of DMA operations and  
+use it for allocations through rte_malloc or rte_mempool.
+
+This feature should work for both uio and vfio. There are no performance 
+requirements around how quickly new memory can be registered or unregistered, 
+but calls to translate virtual to physical addresses should remain fast. 
+
+It is a feature related with DPDK's ``Memory System Redesign`` sub task 
+``Register/unregister memory with vfio dynamically``.
+
+Prerequisites
+-------------
+2xNICs (2 full duplex optical ports per NIC)
+    no nic type limitation
+
+bind port number::
+    one port
+    four port
+
+driver::
+    vfio-pci
+    igb_uio 
+
+HW configuration
+----------------
+1U socket/2U socket::
+    SuperMicro 1U Xeon D Broadwell SoC uServer(1U Socket)
+    Broadwell-EP Xeon E5-2600(2U Socket)
+
+Test cases
+----------
+
+DPDK has no custom example or unit test binary to test memory register/
+unregister. The idea behind the testing process is to run dpdk unit test related 
+with memory. It is the only method to test this feature. `Memory System Redesign` 
+task is related with all dpdk memory management mechanism, including 
+malloc/mbuf/memory/mempool/memcpy/memzone. Run Compound test based on 
+driver/port number/socket type
+
+ Test Case : dpdk malloc autotest
+=================================
+*. bind ports
+
+   ./usertools/dpdk_nic_bind.py --bind=<driver> <pci address>
+
+*. boot up unit test binary ``test``
+
+    ./test/app/test -n 1 -c f
+
+*. run malloc_autotest
+
+    RTE>> malloc_autotest
+ 
+*. check ``test ok`` in output
+
+ Test Case : dpdk mbuf autotest
+===============================
+*. bind ports
+
+   ./usertools/dpdk_nic_bind.py --bind=<driver> <pci address>
+
+*. boot up unit test binary ``test`` 
+
+    ./test/app/test -n 1 -c f
+
+*. run mbuf_autotest
+
+    RTE>> mbuf_autotest
+ 
+*. check ``test ok`` in output
+
+ Test Case : dpdk memcpy autotest
+=================================
+*. bind ports
+  
+   ./usertools/dpdk_nic_bind.py --bind=<driver> <pci address>
+
+*. boot up unit test binary ``test`` 
+
+    ./test/app/test -n 1 -c f
+
+*. run memcpy_autotest
+
+    RTE>> memcpy_autotest
+ 
+*. check ``test ok`` in output
+
+ Test Case : dpdk memcpy perf autotest
+======================================
+*. bind ports
+  
+   ./usertools/dpdk_nic_bind.py --bind=<driver> <pci address>
+
+*. boot up unit test binary ``test`` 
+
+    ./test/app/test -n 1 -c f
+
+*. run memcpy_perf_autotest
+
+    RTE>> memcpy_perf_autotest
+ 
+*. check ``test ok`` in output
+
+ Test Case : dpdk memory autotest
+=================================
+*. bind ports
+  
+   ./usertools/dpdk_nic_bind.py --bind=<driver> <pci address>
+
+*. boot up unit test binary ``test`` 
+
+    ./test/app/test -n 1 -c f
+
+*. run memory_autotest
+
+    RTE>> memory_autotest
+ 
+*. check ``test ok`` in output
+
+Test Case : dpdk mempool autotest
+=================================
+*. bind ports
+  
+   ./usertools/dpdk_nic_bind.py --bind=<driver> <pci address>
+
+*. boot up unit test binary ``test`` 
+
+    ./test/app/test -n 1 -c f
+
+*. run mempool_autotest
+
+    RTE>> mempool_autotest

+ Test Case : dpdk mempool perf autotest
+=======================================
+*. bind ports

+   ./usertools/dpdk_nic_bind.py --bind=<driver> <pci address>
+
+*. boot up unit test binary ``test`` 
+
+    ./test/app/test -n 1 -c f
+
+*. run mempool_perf_autotest
+
+    RTE>> mempool_perf_autotest
+ 
+*. check ``test ok`` in output
+
+ Test Case : dpdk memzone autotest
+==================================
+*. bind ports
+  
+   ./usertools/dpdk_nic_bind.py --bind=<driver> <pci address>
+
+*. boot up unit test binary ``test`` 
+
+    ./test/app/test -n 1 -c f
+
+*. run memzone_autotest
+
+    RTE>> memzone_autotest
