CSIT TOI
Based on CSIT committers availability, current proposal is to hold two separate 1hr sessions:
TOI-1: Tue 23-Jan 07:00-08:00 PST / 15:00-16:00 UTC / 16:00-17:00 CET TOI-1: Fri 31-Jan 07:00-08:00 PST / 15:00-16:00 UTC / 16:00-17:00 CET

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
- only show failing tests
No guarantee that the tests are failing because of arm.

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
- 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)
