Subject: [dts] [Patch V1] test_plans: add test plan for exception path sample
Date: Mon, 18 Feb 2019 09:46:53 +0000 [thread overview]
Message-ID: <1550483213-68537-1-git-send-email-lei.a.yao@intel.com> (raw)
From: Lei Yao <lei.a.yao@intel.com>
This patch will add the test plan for exception path sample. The first
patch will just include the performance test which is based on Ixia

+DPDK Exception Path Sample Tests
+================================
+
+Description
+===========
+
+The Exception Path sample application is a simple example that demonstrates
+the use of the DPDK to set up an exception path for packets to go through
+the Linux* kernel. This is done by using virtual TAP network interfaces.
+These can be read from and written to by the DPDK application and appear
+to the kernel as a standard network interface.
+
+The application creates two threads for each NIC port being used. One thread
+reads from the port and writes the data unmodified to a thread-specific TAP
+interface. The second thread reads from a TAP interface and writes the data
+unmodified to the NIC port.
+
+Prerequisites
+=============
+
+Two NIC ports and Iixa port are needed for this performance test.
+
+
+Test Case: Exception Path Performance test
+==========================================
+1. Bind two NIC ports to DPDK driver, for example
+ usertools/dpdk-devbind.py --bind=vfio-pci device_bus_id1 device_bus_id2
+
+2. Test Performance with 2 Cores and 1 NIC port. 1 core is for NIC RX side
+ and another core is for NIX TX side. For example:
+ ./examples/exception_path/build/exception_path -n 4 -c 0x03 -- -p 0x1 -i 0x01 -o 0x02
+
+3. Configure the two TAP interface generated by the exception path sample and
+ add bridge for packets routing
+ ifconfig tap_dpdk_22 up
+ ifconfig tap_dpdk_23 up
+ brctl addbr "br_dpdk_00"
+ brctl addif br_dpdk_00 tap_dpdk_22
+ brctl addif br_dpdk_00 tap_dpdk_23
+ ifconfig br_dpdk_00 up
+
+4. From packets generator, send broadcast packets to the NIC and check the
+ throughput
+
+5. Similar to Step2~Step4, Test performance with 4 cores and 2 NIC ports.
+ ./examples/exception_path/build/exception_path -n 4 -c 0x0f -- -p 0x3 -i 0x03 -o 0x0C
+ ifconfig tap_dpdk_22 up
+ ifconfig tap_dpdk_23 up
+ brctl addbr "br_dpdk_00"
+ brctl addif br_dpdk_00 tap_dpdk_22
+ brctl addif br_dpdk_00 tap_dpdk_23
+ ifconfig br_dpdk_00 up
+ ifconfig tap_dpdk_24 up
+ ifconfig tap_dpdk_25 up
+ brctl addbr "br_dpdk_01"
+ brctl addif br_dpdk_01 tap_dpdk_24
+ brctl addif br_dpdk_01 tap_dpdk_25
+ ifconfig br_dpdk_01 up
+
+6. From packets generator, send broadcast packets to both 2 NICs then check the
+ aggregated throughput
