Re: [dts] Minimum Tester/DUT configuration

Hi,

After removing all of the dpdk versions on our DUT and tester, updating all packages we were able to get past this issue.  

Our goal is to get a baseline using the Fortville spirit on our DUT before we replace it with our hardware and PMD.  I am running the majority of the tests available in DTS with two Fortville eagles on the tester and 1 Fortville spirit in the DUT configured as a 4x10 NIC.   As you can see from the test_results.xls file that i attached, some tests are passing and some failing.  Many of the failing tests are a result of hardcoded core masks in the tests as both our DUT and tester are single socket boards with 4 core processors.  However some tests like l2fwd are failing and we are not sure why.  We have attached the dts.log file and the l2fwd results file in the hope that you can tell us why this test fails with our setup.  Note that i had to change the following line TestSuite_l2fwd.py because it was trying to force the test to use ports on different NIC’s.

-        self.dut_ports = self.dut.get_ports_performance()

+
+        self.dut_ports = self.dut.get_ports_performance( nic_type='any', perf=None, socket=None,
+                                                         force_same_socket=True,
+                                                         force_different_nic=False)



We see this in the dts log       DTS_DUT_RESULT: [192.168.0.5] There are some dpdk process not free hugepage 

But it looks like a warning in the code and we can see that the on the DUT huge pages are allocated and free.

Also, we are seeing this error in the dts.log at the end of the dpdk build, "Installation cannot run with T defined and DESTDIR undefined"
It appears that the build is complete and since DTS does not actually do a dpdk install we think this is ok, but are not sure why the error is happening.

Any help or insight that you could provide to help us get our baseline system functional using the Intel Fortville NIC’s would be appreciated.

Thank you,
-John
