Subject: [dts][PATCH V3 1/2] test_plans/vhost_virtio_pmd_interrupt_cbdma_test_plan: modify the dmas parameter by DPDK changed
Date: Tue, 22 Nov 2022 14:24:36 +0800 [thread overview]
Message-ID: <20221122062436.2892449-1-weix.ling@intel.com> (raw)
From DPDK-22.11, the dmas parameter have changed, so modify the dmas
parameter in the testplan.

3. Bind virtio port to vfio-pci::
- modprobe vfio enable_unsafe_noiommu_mode=1
- modprobe vfio-pci
- ./usertools/dpdk-devbind.py --bind=vfio-pci xx:xx.x
+ modprobe vfio enable_unsafe_noiommu_mode=1
+ modprobe vfio-pci
+ ./usertools/dpdk-devbind.py --bind=vfio-pci xx:xx.x
4. In VM, launch l3fwd-power sample::
- ./x86_64-native-linuxapp-gcc/examples/dpdk-l3fwd-power -c 0x0ffff -n 4 --log-level='user1,7' -- -p 1 -P --config '(0,0,0),(0,1,1),(0,2,2),(0,3,3)(0,4,4),(0,5,5),(0,6,6),(0,7,7)(0,8,8),(0,9,9),(0,10,10),(0,11,11)(0,12,12),(0,13,13),(0,14,14),(0,15,15)' --no-numa --parse-ptype
+ ./x86_64-native-linuxapp-gcc/examples/dpdk-l3fwd-power -c 0x0ffff -n 4 --log-level='user1,7' -- -p 1 -P --config '(0,0,0),(0,1,1),(0,2,2),(0,3,3)(0,4,4),(0,5,5),(0,6,6),(0,7,7)(0,8,8),(0,9,9),(0,10,10),(0,11,11)(0,12,12),(0,13,13),(0,14,14),(0,15,15)' --no-numa --parse-ptype
5. Send random dest IP packets to host NIC with packet generator, packets will distribute to all queues, check l3fwd-power log that all related cores are waked up.
