VPP_Device Functional
---------------------
-|csit-release| added new VPP_Device test environment for functional VPP
+|csit-release| includes VPP_Device test environment for functional VPP
device tests integrated into LFN CI/CD infrastructure. VPP_Device tests
run on 1-Node testbeds (1n-skx, 1n-arm) and rely on Linux SRIOV Virtual
Function (VF), dot1q VLAN tagging and external loopback cables to
facilitate packet passing over exernal physical links. Initial focus is
-on few baseline tests. Existing CSIT VIRL tests can be moved to
-VPP_Device framework by changing L1 and L2 KW(s). RF test definition
-code stays unchanged with the exception of requiring adjustments from
-3-Node to 2-Node logical topologies. CSIT VIRL to VPP_Device migration
-is expected in the next CSIT release.

-Linux CFS Tunings
-~~~~~~~~~~~~~~~~~
-
-Linux CFS scheduler tunings are applied to all QEMU vCPU worker threads
-(the ones handling testpmd PMD threads) and VPP data plane worker
-threads. List of VPP data plane threads can be obtained by running:
-
-::
-
- $ for psid in $(pgrep vpp)
- $ do
- $ for tid in $(ps -Lo tid --pid $psid | grep -v TID)
- $ do
- $ echo $tid
- $ done
- $ done
-
-Or:
-
-::
-
- $ cat /proc/`pidof vpp`/task/*/stat | awk '{print $1" "$2" "$39}'
-
-CFS round-robin scheduling with highest priority is applied using:
-
-::
-
- $ for psid in $(pgrep vpp)
- $ do
- $ for tid in $(ps -Lo tid --pid $psid | grep -v TID)
- $ do
- $ chrt -r -p 1 $tid
- $ done
- $ done
-
-More information about Linux CFS can be found in `Sched manual pages
-<http://man7.org/linux/man-pages/man7/sched.7.html>`_.
