207. Eventdev Tests

207.1. 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

207.2. Create huge pages

mkdir -p /dev/huge mount -t hugetlbfs none /dev/huge echo 24 > /proc/sys/vm/nr_hugepages

207.3. 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 256
  • eventdev_device_bus_id/limits/ssow: Max limit 52
