+=====================
+One-shot Rx Interrupt
+=====================
+One-shot Rx interrupt feature will split rx interrupt handling from other
+interrupts like LSC interrupt. It implemented one handling mechanism to
+eliminate non-deterministic DPDK polling thread wakeup latency.
+
+VFIO' multiple interrupt vectors support mechanism to enable multiple event fds
+serving per Rx queue interrupt handling.
+UIO has limited interrupt support, specifically it only support a single
+interrupt vector, which is not suitable for enabling multi queues Rx/Tx
+interrupt.
+
+Prerequisites
+=============
+Each of the 10Gb Ethernet* ports of the DUT is directly connected in
+full-duplex to a different port of the peer traffic generator.
+
+Assume PF port PCI addresses are 0000:04:00.0 and 0000:04:00.1, their Interfaces name are p786p1 and p786p2.
+Assume generated VF PCI address will be 0000:04:10.0, 0000:04:10.1.
+
+Iommu pass through feature has been enabled in kernel.
+ intel_iommu=on iommu=pt
+
+Support igb_uio and vfio driver, if used vfio, kernel need 3.6+ and enable vt-d
+in bios. When used vfio, requested to insmod two drivers vfio and vfio-pci.
+
+Test Case1: VF interrupt pmd in VM with uio
+===========================================
+Create one VF per Port in host and add these two VFs into VM:
+ usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:04:00.0 0000:04:00.1
+ echo 1 >/sys/bus/pci/devices/0000\:04\:00.0/max_vfs
+ echo 1 >/sys/bus/pci/devices/0000\:04\:00.1/max_vfs
+ usertools/dpdk-devbind.py --force --bind=pci-stub 0000:04:10.0 0000:04:10.1
+
+Start VM and start l3fwd-power with one queue per port in VM:
+ l3fwd-power -c 7 -n 4 -- -p 0x3 -P --config="(0,0,1),(1,0,2)"
+
+Send one packet to VF0 and VF1, check that thread on core1 and core2 waked up:
+ L3FWD_POWER: lcore 1 is waked up from rx interrupt on port1,rxq0
+ L3FWD_POWER: lcore 2 is waked up from rx interrupt on port1,rxq0
+
+Check the packet has been normally forwarded.
+
+After the packet forwarded, thread on core1 and core 2 will return to sleep.
+ L3FWD_POWER: lcore 1 sleeps until interrupt on port0,rxq0 triggers
+ L3FWD_POWER: lcore 2 sleeps until interrupt on port0,rxq0 triggers
+
+Send packet flows to VF0 and VF1, check that thread on core1 and core2 will
+keep up awake.
+
+Test Case2: VF interrupt pmd in Host with uio
+=============================================
+Create one VF per Port in host and make sure PF interface up
+ues kernel driver to create vf:
+ echo 1 >/sys/bus/pci/devices/0000\:04\:00.1/sriov_numvf
+ echo 1 >/sys/bus/pci/devices/0000\:04\:00.1/sriov_numvf
+
+Bind VF device to igb_uio:
+ ./usertools/dpdk-devbind.py --bind=igb_uio 0000:04:10.0 0000:04:10.1
+
+Start host and start l3fwd-power with one queue per port in host:
+ l3fwd-power -c 7 -n 4 -- -p 0x3 -P --config="(0,0,1),(1,0,2)"
+
+Send one packet to VF0 and VF1, check that thread on core1 and core2 waked up:
+ L3FWD_POWER: lcore 1 is waked up from rx interrupt on port1,rxq0
+ L3FWD_POWER: lcore 2 is waked up from rx interrupt on port1,rxq0
+
+Check the packet has been normally forwarded.
+
+After the packet forwarded, thread on core1 and core 2 will return to sleep.
+ L3FWD_POWER: lcore 1 sleeps until interrupt on port0,rxq0 triggers
+ L3FWD_POWER: lcore 2 sleeps until interrupt on port0,rxq0 triggers
+
+Send packet flows to VF0 and VF1, check that thread on core1 and core2 will
+keep up awake.
+
+Test Case3: VF interrupt pmd in Host with vfio
+==============================================
+Create one VF per Port in host and make sure PF interface up
+ues kernel driver to create vf:
+ echo 1 >/sys/bus/pci/devices/0000\:04\:00.1/sriov_numvf
+ echo 1 >/sys/bus/pci/devices/0000\:04\:00.1/sriov_numvf
+
+Bind VF device to host igb_uio:
+ ./usertools/dpdk-devbind.py --bind=vfio-pci 0000:04:10.0 0000:04:10.1
+
+Start VM and start l3fwd-power with two queues per port in VM:
+ l3fwd-power -c 1f -n 4 -- -p 0x3 -P \
+ --config="(0,0,1),(0,1,2)(1,0,3),(1,1,4)"
+
+Send packets with increased dest IP to Port0 and Port1, check that thread on
+core1,core2,core3,core4 waked up:
+ L3FWD_POWER: lcore 1 is waked up from rx interrupt on port1,rxq0
+ L3FWD_POWER: lcore 2 is waked up from rx interrupt on port1,rxq1
+ L3FWD_POWER: lcore 3 is waked up from rx interrupt on port1,rxq0
+ L3FWD_POWER: lcore 4 is waked up from rx interrupt on port1,rxq1
+
+Check the packet has been normally forwarded.
+
+After the packet forwarded, thread on core1,core2,core3,core4 will return to

+=====================
+One-shot Rx Interrupt
+=====================
+One-shot Rx interrupt feature will split rx interrupt handling from other
+interrupts like LSC interrupt. It implemented one handling mechanism to
+eliminate non-deterministic DPDK polling thread wakeup latency.
+
+VFIO' multiple interrupt vectors support mechanism to enable multiple event fds
+serving per Rx queue interrupt handling.
+UIO has limited interrupt support, specifically it only support a single
+interrupt vector, which is not suitable for enabling multi queues Rx/Tx
+interrupt.
+
+Prerequisites
+=============
+Each of the 10Gb Ethernet* ports of the DUT is directly connected in
+full-duplex to a different port of the peer traffic generator.
+
+Assume PF port PCI addresses are 0000:04:00.0 and 0000:04:00.1, their Interfaces name are p786p1 and p786p2.
+Assume generated VF PCI address will be 0000:04:10.0, 0000:04:10.1.
+
+Iommu pass through feature has been enabled in kernel.
+ intel_iommu=on iommu=pt
+
+Support igb_uio and vfio driver, if used vfio, kernel need 3.6+ and enable vt-d
+in bios. When used vfio, requested to insmod two drivers vfio and vfio-pci.
+
+Test Case1: VF interrupt pmd in VM with uio
+===========================================
+Create one VF per Port in host and add these two VFs into VM:
+ usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:04:00.0 0000:04:00.1
+ echo 1 >/sys/bus/pci/devices/0000\:04\:00.0/max_vfs
+ echo 1 >/sys/bus/pci/devices/0000\:04\:00.1/max_vfs
+ usertools/dpdk-devbind.py --force --bind=pci-stub 0000:04:10.0 0000:04:10.1
+
+Start VM and start l3fwd-power with one queue per port in VM:
+ l3fwd-power -c 7 -n 4 -- -p 0x3 -P --config="(0,0,1),(1,0,2)"
+
+Send one packet to VF0 and VF1, check that thread on core1 and core2 waked up:
+ L3FWD_POWER: lcore 1 is waked up from rx interrupt on port1,rxq0
+ L3FWD_POWER: lcore 2 is waked up from rx interrupt on port1,rxq0
+
+Check the packet has been normally forwarded.
+
+After the packet forwarded, thread on core1 and core 2 will return to sleep.
+ L3FWD_POWER: lcore 1 sleeps until interrupt on port0,rxq0 triggers
+ L3FWD_POWER: lcore 2 sleeps until interrupt on port0,rxq0 triggers
+
+Send packet flows to VF0 and VF1, check that thread on core1 and core2 will
+keep up awake.
+
+Test Case2: VF interrupt pmd in Host with uio
+=============================================
+Create one VF per Port in host and make sure PF interface up
+ues kernel driver to create vf:
+ echo 1 >/sys/bus/pci/devices/0000\:04\:00.1/sriov_numvf
+ echo 1 >/sys/bus/pci/devices/0000\:04\:00.1/sriov_numvf
+
+Bind VF device to igb_uio:
+ ./usertools/dpdk-devbind.py --bind=igb_uio 0000:04:10.0 0000:04:10.1
+
+Start host and start l3fwd-power with one queue per port in host:
+ l3fwd-power -c 7 -n 4 -- -p 0x3 -P --config="(0,0,1),(1,0,2)"
+
+Send one packet to VF0 and VF1, check that thread on core1 and core2 waked up:
+ L3FWD_POWER: lcore 1 is waked up from rx interrupt on port1,rxq0
+ L3FWD_POWER: lcore 2 is waked up from rx interrupt on port1,rxq0
+
+Check the packet has been normally forwarded.
+
+After the packet forwarded, thread on core1 and core 2 will return to sleep.
+ L3FWD_POWER: lcore 1 sleeps until interrupt on port0,rxq0 triggers
+ L3FWD_POWER: lcore 2 sleeps until interrupt on port0,rxq0 triggers
+
+Send packet flows to VF0 and VF1, check that thread on core1 and core2 will
+keep up awake.
+
+Test Case3: VF interrupt pmd in Host with vfio
+==============================================
+Create one VF per Port in host and make sure PF interface up
+ues kernel driver to create vf:
+ echo 1 >/sys/bus/pci/devices/0000\:04\:00.1/sriov_numvf
+ echo 1 >/sys/bus/pci/devices/0000\:04\:00.1/sriov_numvf
+
+Bind VF device to host igb_uio:
+ ./usertools/dpdk-devbind.py --bind=vfio-pci 0000:04:10.0 0000:04:10.1
+
+Start VM and start l3fwd-power with two queues per port in VM:
+ l3fwd-power -c 1f -n 4 -- -p 0x3 -P \
+ --config="(0,0,1),(0,1,2)(1,0,3),(1,1,4)"
+
+Send packets with increased dest IP to Port0 and Port1, check that thread on
+core1,core2,core3,core4 waked up:
+ L3FWD_POWER: lcore 1 is waked up from rx interrupt on port1,rxq0
+ L3FWD_POWER: lcore 2 is waked up from rx interrupt on port1,rxq1
+ L3FWD_POWER: lcore 3 is waked up from rx interrupt on port1,rxq0
+ L3FWD_POWER: lcore 4 is waked up from rx interrupt on port1,rxq1
+
+Check the packet has been normally forwarded.
+
+After the packet forwarded, thread on core1,core2,core3,core4 will return to
+sleep.
+ L3FWD_POWER: lcore 1 sleeps until interrupt on port0,rxq0 triggers
+ L3FWD_POWER: lcore 2 sleeps until interrupt on port0,rxq1 triggers
+ L3FWD_POWER: lcore 3 sleeps until interrupt on port1,rxq0 triggers
+ L3FWD_POWER: lcore 4 sleeps until interrupt on port1,rxq1 triggers
+
+Send packet flows to Port0 and Port1, check that thread on core1,core2,core3,
+core4 will keep up awake.
