These test suites\n+cover a variety of kernel modules and are built to check their function\n+both in use as root and as an unprivileged user. All of the test suites\n+run the same tests. In the documentation for test cases, <MODULE> will\n+represent the name of the module being tested. <DEV INTERFACE> will\n+represent the character interface under /dev/ for the interface.\n+\n+Prerequisites\n+=============\n+\n+There are two prerequisites. First, all of the drivers that you wish\n+to test must be compiled and installed so that they are available through\n+modprobe. Secondly, there should be a user on the dut which has the same\n+password as the primary account for dts. This account will be used as the\n+unprivileged user, but it still should have permission to lock at least\n+1 GiB of memory to ensure that it can lock all of the process memory.\n+\n+Test Suites\n+===========\n+\n+There is 1 test suite per module, the modules are as follows:\n+\n+ * VFIO-PCI\n+ * UIO PCI GENERIC\n+ * IGB UIO\n+\n+Test Case: TX RX\n+====================\n+This test case runs as root and is designed to check the basic functioning\n+of the module. It checks whether packets can be sent and received.\n+\n+Remove old module ::\n+\n+ # rmmod <MODULE>\n+\n+Add the new one ::\n+\n+ # modprobe <MODULE>\n+\n+Bind the interface to the driver ::\n+\n+ # usertools/dpdk-devbind.py --force --bind=<MODULE> xxxx:xx:xx.x\n+\n+Start testpmd in a loop configuration ::\n+\n+ # x86_64-native-linux-gcc/app/testpmd -l 1,2 -n 4 -w xxxx:xx:xx.x \\\n+ -- -i --port-topology=loop\n+\n+Start packet forwarding ::\n+\n+ testpmd> start\n+\n+Start a packet capture on the tester::\n+\n+ # tcpdump -i (interface) ether src (tester mac address)\n+\n+Send some packets to the dut and check that they are properly sent back into\n+the packet capture on the tester.\n+\n+Test Case: TX RX Userspace\n+====================\n+This test case runs as the unprivileged user and is designed to check the\n+basic functioning of the module. It checks whether packets can be sent\n+and received when running dpdk applications as a normal user. # means\n+that a command is run as root. $ means that a command is run as the user.\n+The igb_uio module requires that the iova mode is in virtual address mode,\n+which can be done by adding the flag \"--iova-mode va\" as an eal option to\n+testpmd.\n+\n+Remove old module ::\n+\n+ # rmmod <MODULE>\n+\n+Add the new one ::\n+\n+ # modprobe <MODULE>\n+\n+Bind the interface to the driver ::\n+\n+ # usertools/dpdk-devbind.py --force --bind=<MODULE> xxxx:xx:xx.x\n+\n+Grant permissions for all users to access the new character device ::\n+\n+ # setfacl -m u:dtsunprivilegedtester:rwx <DEV INTERFACE>\n+\n+Start testpmd in a loop configuration ::\n+\n+ $ x86_64-native-linux-gcc/app/testpmd -l 1,2 -n 4 -w xxxx:xx:xx.x --in-memory \\\n+ -- -i --port-topology=loop\n+\n+Start packet forwarding ::\n+\n+ testpmd> start\n+\n+Start a packet capture on the tester::\n+\n+ # tcpdump -i (interface) ether src (tester mac address)\n+\n+Send some packets to the dut and check that they are properly sent back into\n+the packet capture on the tester.\n+\n+Test Case: Hello World\n+====================\n+This is a more basic test of functionality as a normal user than the\n+TX RX Userspace case. It simply involves running a short, hello-world-like\n+program on each core before shutting down. # means that a command is run\n+as root. $ means that a command is run as the user. The igb_uio module\n+requires that the iova mode is in virtual address mode, which can be done\n+by adding the flag \"--iova-mode va\" as an eal option to the hello world\n+application.\n+\n+Compile the application ::\n+\n+ # cd $RTE_SDK/examples/helloworld && make\n+\n+Run the application ::\n+\n+ $ $RTE_SDK/examples/helloworld/build/helloworld-shared --in-memory\n+\n+Check for any error states or reported errors.\n+\ndiff --git a/tests/TestSuite_linux_modules.py b/tests/TestSuite_linux_modules.py\nnew file mode 100644\nindex 0000000..7cb479d\n--- /dev/null\n+++ b/tests/TestSuite_linux_modules.py\n@@ -0,0 +1,173 @@\n+# BSD LICENSE\n+#\n+# Copyright(c) 2010-2014 Intel Corporation.
