DPDK ArmV7 autotests

Hello David,

I am working on some auto test in QEMU. My last result for ARMv7 is following bellow. What is strange, I could see that the read/write lock autotest failed (wrong order) before.

I have no idea what does it mean "no prompt". I suppose that such test could not be run for some reason...

I had to slightly modify the autotest.py to run properly.

The test was executed in qemu:

qemu-system-arm -M vexpress-a9 -kernel zImage \
-dtb vexpress-v2p-ca9.dtb -drive file=rootfs.ext2,if=sd \
-append "console=ttyAMA0 root=/dev/mmcblk0 rw" -smp 4 -m 512 -nographic

with the Linux Kernel 4.2.

The no prompt occurs when the 'test' binary (which is used to run each autotest in turn) exits before it gets to the prompt, so the test cannot be run. Usually this is because of lack of resources such as memory, PCI or similar. I had to reduce the memory requirements from 1024M to 512M to get one section of tests to pass (in autotest_data.py).

For more information on why the autotests are failing, you can check the log file in the directory for that autotest run - arm-armv7a-linux-app-gcc/autotest-date/arm-armv7a-linuxapp-gcc.log

Here is the log. You an see, that many tests fail just because of the missing hugetlb support. This is strange as I modified the autotest_runner.py to inject "--no-huge --no-pci" options when it detects armv7 architecture.

Moreover, the mempool performance test does not say OK. It is marked as Timeout in the CSV.

The argument format is <c1>[-c2][,c3[-c4],...] where c1, c2, etc are core indexes between 0 and 128
--lcores COREMAP Map lcore set to physical cpu set
The argument format is
'<lcores[@cpus]>[<,lcores[@cpus]>...]'
lcores and cpus list are grouped by '(' and ')' Within the group, '-' is used for range separator, ',' is used for single number separator.
'( )' can be omitted for single element group, '@' can be omitted if cpus and lcores have the same value

  --master-lcore ID   Core ID that is used as master
  -n CHANNELS         Number of memory channels
  -m MB               Memory to allocate (see also --socket-mem)

I think publishing these test results to the mailing list confuses matters somewhat. The tests are not tuned for armv7, and there are many false negatives, giving the impression that the results are worse than they actually should be.

The tests need to be analysed to see if they respect the --no-huge and --no-pci flags correctly, I suspect some tests are being run even though these flags are enabled.

I believe enough of the tests pass to allow the initial version of the patch set to be accepted. We can look at the failing cases later, and improve the test suite as time goes on.

Thanks,
Dave.

2015-11-10 10:22, Hunt, David:

I agree.
The unit tests are know to require some refactoring.
I suggest to continue ARM integration while checking how to fix the unit tests later. Maybe that Declan has some ideas or plans about the tests.

Make sense.

I have tried autotest on armv8, results looks very promising.

Few more features need for armv8 port like lpm, optimized hash, removing x86 dependencies from examples directory etc.
But these needs change in the common code
so IMO have existing code as base port and common code changes we will add step by step otherwise it will be difficult manage.
