ACC100 LDPC DPDK BBdev validation

I am experiencing some issues when trying to set up the ACC100 LDPC card. While following the steps from pf-bb-config However, we experience the following issues:

Baseband devices using DPDK-compatible driver ============================================= 0000:ca:00.0 'Device 0d5c' drv=vfio-pci unused= 0000:cb:00.0 'Device 0d5d' drv=vfio-pci unused= 0000:cb:00.1 'Device 0d5d' drv=vfio-pci unused= zq40@tc319-srv2:/opt/dpdk-stable-21.11.2-older/app/test-bbdev$ dmesg | grep "DMAR: IOMMU" [ 0.457583] DMAR: IOMMU enabled [ 0.457977] DMAR: IOMMU enabled zq40@tc319-srv2:/opt/dpdk-stable-21.11.2/app/test-bbdev/test_vectors$ sudo dpdk-test-bbdev -c F0 -a cb:00.0 --vfio-vf-token=513acf7e-2f25-11ee-bde0-9362ebeeb1a6 -- -c validation -v ldpc_dec_v2342_drop.data [sudo] password for zq40: EAL: Detected 56 lcore(s) EAL: Detected 2 NUMA nodes Option -w, --pci-whitelist is deprecated, use -a, --allow option instead EAL: Detected static linkage of DPDK EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'VA' EAL: Probing VFIO support...

We followed the pf_bb_config README and configured the ACC100 as directed by the tutorial, but it seems that the function fails when trying to set up queues.

The other thing we tried instead is to use igb_uio to drive our acc100 card,

sudo dpdk-devbind.py -b igb_uio ca:00.0 zq40@tc319-srv2:/opt/dpdk-stable-20.11.5/app/test-bbdev$ cat /sys/bus/pci/devices/0000\:ca\:00.0/sriov_totalvfs 16 echo 16 | sudo tee /sys/bus/pci/devices/0000\:ca\:00.0/max_vfs echo 16 | sudo tee /sys/bus/pci/devices/0000\:ca\:00.0/sriov_numvfs

I tried both to configure the VFs through PF by both trying the vf/pf.cfg from the pf_bb_config. And we are able to avoid the previous error we saw when setting up the queues as:

zq40@tc319-srv2:/opt/dpdk-stable-20.11.5/app/test-bbdev$ sudo dpdk-test-bbdev -c F0 -a cb:00.0 --vfio-vf-token=513acf7e-2f25-11ee-bde0-9362ebeeb1a6 -- -c validation -v ./ldpc_dec_default.data EAL: Detected 56 lcore(s) EAL: Detected 2 NUMA nodes EAL: Detected static linkage of DPDK EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'PA' EAL: Probing VFIO support...

The test program just hung there with no progress.

It would be much appreciated if you could provide any help, I have also attached .txt files including the printouts by running test-bbdev with strace.
