[dts] [PATCH] add l3fwd exact match perf test script and plan

Wed Mar 16 06:29:46 CET 2016
Add l3fwd exact match perf test script and plan.
1. Separate l3fwd lpm and exact match performance test script and plan
because they have different ways. Previous l3fwd perf test is l3fwd lpm
perf test. Add new exact match perf test.
2. Update the test plan and script for l3fwd exact match, remove 4port
case and added the hash-entry-number for perf check. Updated the traffic,
sample command for 2 ports.

+==============================
+Layer-3 Forwarding Exact Match
+==============================
+
+The Layer-3 Forwarding results are produced using ``l3fwd`` application.
+
+Prerequisites
+=============
+
+1. Hardware requirements:
+
+ - For each CPU socket, each memory channel should be populated with at least 1x DIMM
+ - Board is populated with 4x 1GbE or 10GbE ports. Special PCIe restrictions may
+ be required for performance. For example, the following requirements should be
+ met for Intel 82599 (Niantic) NICs:
+
+ - NICs are plugged into PCIe Gen2 or Gen3 slots
+ - For PCIe Gen2 slots, the number of lanes should be 8x or higher
+ - A single port from each NIC should be used, so for 4x ports, 4x NICs should
+ be used
+
+ - NIC ports connected to traffic generator. It is assumed that the NIC ports
+ P0, P1, P2, P3 (as identified by the DPDK application) are connected to the
+ traffic generator ports TG0, TG1, TG2, TG3. The application-side port mask of
+ NIC ports P0, P1, P2, P3 is noted as PORTMASK in this section.
+
+2. BIOS requirements:
+
+ - Intel Hyper-Threading Technology is ENABLED
+ - Hardware Prefetcher is DISABLED
+ - Adjacent Cache Line Prefetch is DISABLED
+ - Direct Cache Access is DISABLED
+
+3. Linux kernel requirements:
+
+ - Linux kernel has the following features enabled: huge page support, UIO, HPET
+ - Appropriate number of huge pages are reserved at kernel boot time
+ - The IDs of the hardware threads (logical cores) per each CPU socket can be
+ determined by parsing the file /proc/cpuinfo. The naming convention for the
+ logical cores is: C{x.y.z} = hyper-thread z of physical core y of CPU socket x,
+ with typical values of x = 0 .. 3, y = 0 .. 7, z = 0 .. 1. Logical cores
+ C{0.0.1} and C{0.0.1} should be avoided while executing the test, as they are
+ used by the Linux kernel for running regular processes.
+
+4. Software application requirements
+
+5. Support igb_uio and vfio driver, if used vfio, kernel need 3.6+ and enable vt-d in bios.
+When used vfio , used "modprobe vfio" and "modprobe vfio-pci" insmod vfiod driver, then used
+"./tools/dpdk_nic_bind.py --bind=vfio-pci device_bus_id" to bind vfio driver to test driver.
+
+
+- In hash mode, the hash table used for packet routing is:
+
+|
+
++-------+-------------+-----------+-------------+-----------+-----------+--------+
+| Entry | IPv4 | IPv4 | Port | Port | L4 | Output |
+| # | destination | source | destination | source | protocol | port |
+| | address | address | | | | |
++-------+-------------+-----------+-------------+-----------+-----------+--------+
+| 0 | 201.0.0.0 | 200.20.0.1| 102 | 12 | TCP | P1 |
++-------+-------------+-----------+-------------+-----------+-----------+--------+
+| 1 | 101.0.0.0 | 100.10.0.1| 101 | 11 | TCP | P0 |
++-------+-------------+-----------+-------------+-----------+-----------+--------+
+| 2 | 211.0.0.0 | 200.40.0.1| 102 | 12 | TCP | P3 |
++-------+-------------+-----------+-------------+-----------+-----------+--------+
+| 3 | 111.0.0.0 | 100.30.0.1| 101 | 11 | TCP | P2 |
++-------+-------------+-----------+-------------+-----------+-----------+--------+
+
+
+6. Traffic generator requirements
+
+The flows need to be configured and started by the traffic generator:
+
+|
+
++------+---------+----------+-----------+------+-------+--------+----------------------------------+
+| Flow | Traffic | IPv4 | IPv4 | Port | Port | L4 | IPv4 |
+| | Gen. | Dst. | Src. | Dst. | Src. | Proto. | Dst Addr |
+| | Port | Address | Address | | | | Mask(Continuous Increment Host) |
++------+---------+----------+-----------+------+-------+--------+----------------------------------+
+| 1 | TG0 | 201.0.0.0| 200.20.0.1| 102 | 12 | TCP | 255.240.0.0 |
++------+---------+----------+-----------+------+-------+--------+----------------------------------+
+| 2 | TG1 | 101.0.0.0| 100.10.0.1| 101 | 11 | TCP | 255.240.0.0 |
++------+---------+------------+---------+------+-------+--------+----------------------------------+
+
+
+
+|
+
+The queue column represents the expected NIC port RX queue where the packet
+should be written by the NIC hardware when RSS is enabled for that port.
+
+Test Case: Layer-3 Forwarding (in Hash Mode)
+============================================
+
+The following items are configured through the command line interface of the
+application:
+
+ - The set of one or several RX queues to be enabled for each NIC port
+ - The set of logical cores to execute the packet forwarding task
+ - Mapping of the NIC RX queues to logical cores handling them.
+ - The set of hash-entry-num for the exact match
+
+The test report should provide the throughput rate measurements (in mpps
+and % of the line rate for 4x NIC ports) as listed in the table below:
+
+|
+
++----+---------+---------+-------------+---------+----------+------------------+
+| # |Number of|Total |Number |Total |Number | Throughput Rate |
+| |RX Queues|Number of|of Sockets/ |Number of|of NIX RX | Exact Match Mode |
+| |per NIC |NIC RX |Cores/Threads|Threads |Queues per+------------------+
+| |Port |Queues | | |Thread | mpps | % |
++----+---------+---------+-------------+---------+----------+--------+---------+
+| 1 | 1 |2 |1S/1C/1T |1 |1 | | |
++----+---------+---------+-------------+---------+----------+--------+---------+
+| 2 | 1 |2 |1S/2C/1T |2 |1 | | |
++----+---------+---------+-------------+---------+----------+--------+---------+
+| 3 | 2 |4 |1S/4C/1T |4 |2 | | |
++----+---------+---------+-------------+---------+----------+--------+---------+
+
+
+The application command line associated with each of the above tests is
+presented in the table below. The test report should present this table with
+the actual command line used, replacing the PORTMASK and C{x.y.z} with their
+actual values used during test execution.
+
+|
+
