249. Eventdev Pipeline Perf Tests¶
249.1. Prerequisites¶
Each of the 10Gb/25Gb/40Gb/100Gb Ethernet* ports of the DUT is directly connected in full-duplex to a different port of the peer Ixia ports(traffic generator).
Using TCL commands, the Ixia can be configured to send and receive traffic on a given set of ports.
If using vfio the kernel must be >= 3.6+ and VT-d must be enabled in bios.When using vfio, use the following commands to load the vfio driver and bind it to the device under test
modprobe vfio
modprobe vfio-pci
usertools/dpdk-devbind.py --bind=vfio-pci device_bus_id
usertools/dpdk-devbind.py --bind=vfio-pci eventdev_device_bus_id
- Build dpdk and examples=eventdev_pipeline:
CC=gcc meson -Denable_kmods=True -Dlibdir=lib –default-library=static <build_target> ninja -C <build_target>
meson configure -Dexamples=eventdev_pipeline <build_target> ninja -C <build_target>
249.2. Create huge pages¶
mkdir -p /dev/huge mount -t hugetlbfs none /dev/huge echo 24 > /proc/sys/vm/nr_hugepages
249.3. Configure limits of Eventdev devices¶
Set all eventdev devices sso and ssow limits to zero. Then set eventdev device under tests sso and ssow limits to non-zero values as per cores/queues requriments
echo 0 > /sys/bus/pci/devices/eventdev_device_bus_id/limits/sso
echo 0 > /sys/bus/pci/devices/eventdev_device_bus_id/limits/ssow
Example
echo 0 > /sys/bus/pci/devices/eventdev_device_bus_id/limits/tim
echo 1 > /sys/bus/pci/devices/eventdev_device_bus_id/limits/npa
echo 16 > /sys/bus/pci/devices/eventdev_device_bus_id/limits/sso
echo 32 > /sys/bus/pci/devices/eventdev_device_bus_id/limits/ssow
eventdev_device_bus_id/limits/sso: Max limit 256eventdev_device_bus_id/limits/ssow: Max limit 52
