Hello,
i am using LS2088ardb with QorIQ SDK v2.0-1703.
What is the correct way to use DPDK with DPSW/DPDMUX objects on DPAA2 bus?
I would like to use DPSW and DPDMUX with DPDK application.
(For example L2 switch with 8 ports, 4x10SFP+, 4xDPNI with two queues, 8 GPP cores).
I would also like to configure DPAA2 bus at runtime. F.e. by ls-addni, dynamic_dpl.sh.
Now when run (example mac-sw-ni )
# 1 ni, 1 sfp
ls-addni -n
# ni0 is lost, use ni1
ls-addsw -i=2 dpni.1 dpmac.1
ip link set ni1 down
ip link set ni1 down
ip link set sw0p1 down
# manyally plug unplug, transceiver, they can be in UNKNOWN state
ip link set sw0p1 up
ip link set ni1 up
ip addr add 192.168.1.4/24 dev ni1
# now ping works
I am able to configure DPAA2 bus as I wish. But when I try to bind DPRC to vfio-fsl-mc driver to have DPDK support
it also breaks DPSW driver.
echo 1 > /sys/module/vfio_iommu_type1/parameters/allow_unsafe_interrupts
echo vfio-fsl-mc > /sys/bus/fsl-mc/devices/$DPRC/driver_override
echo $DPRC > /sys/bus/fsl-mc/drivers/vfio-fsl-mc/bind
It breaks drivers of DPSW.
I tried to put DPSW into separate DPRC, but without sucess.
It is possible to make connection between separate DPRC with distinct drivers using restool?
