CSIT/AArch64

CSIT TOI

Based on CSIT committers availability, current proposal is to hold two separate 1hr sessions:

   TOI-1: Fri 02-Feb 07:00-08:00 PST / 15:00-16:00 UTC / 16:00-17:00 CET
   TOI-2: Tue 06-Feb 07:00-08:00 PST / 15:00-16:00 UTC / 16:00-17:00 CET

Proposed agenda:

TOI-1

   1. CSIT overview, goals, releases, high-level design - Maciek - 10min
   2. CSIT libraries, L1/L2 KWs, sample test suites - Tibor - 20min
   3. Performance tests - PeterM - 20min
   4. Q&A - 10min

TOI-2

   1. VIRL functional tests - JanG - 20min
   2. Physical testbeds - PeterM - 10min
   3. VIRL testbeds - EdK - 10min
   4. Q&A - 20min

TEST for 2-nodes topology

(gg) based on my tests, in order to reproduce issues more easily across the team.

• set up 2 aarch64 VMs (TG + DUT)
  • give them 3 interfaces
  • one for management, the other two down for the test
  • compile igb_uio (see known issue #1) and load it
• write topology file with `arch: aarch64`
  • fill pci_address, and mac_address according to your setup
• create virtualenv following csit README
  • virtualenv env
  • source env/bin/activate
  • pip install -r requirements.txt
  • export PATH with vpp_api_test, and PYTHONPATH

cmdline to run functional tests only with debug logs. You need the "__init__.robot" present in the folder you give to pybot.

pybot --debugfile /tmp/debugfile --exitonerror -L TRACE -v TOPOLOGY_PATH:topologies/enabled/topology.yaml tests/vpp/func/

Functional test

Tests status:

• CSIT: 54ad6efd342695d0a7dad5380cc989a8d846f518
• 3-Nodes topology
• On VM only
• honeycomb disabled

No guarantee that the tests are failing because of arm or a bad setup of mine ... 145/199 of the test fail are caused by "Traffic script execution failed"

TODO

• identify ARM64 hardware to replicate CSIT repo
• make Jira EPIC for CSIT func
• make Jira EPIC for CSIT performance

• disk-image-builder scripts
• write a bootstrap-* script for aarch64
• add VPP_REPO_URL* VPP_STABLE_VER* files ... (could be any public server for now)

known issues

1. dpdk does not compiles igb_uio on aarch64 (it seems to require a kernel patch introduced in kernel 4.12: f719582435afe9c7985206e42d804ea6aa315d33). it has been re-enabled in dpdk v17.11 (f1810113590373b157ebba555d6b51f38c8ca10f)
