Hi,
Multiple input/output in test vector is not for multiple code blocks, but as an
option for scatter-gather (data split into 2 pointers for instance for same
code block, ie. not contiguous in memory). If you want to do 2 code blocks,
these would be 2 independent operations and not what you are trying to do below.
Thanks,
Nic

Subject: Multiple paramters of input and output in DPDK-BBdev
Hello Devs,
I hope this email finds you well.
I am reaching out to seek assistance regarding an issue I am facing in
DPDK-BBdev utility, (v22.11).
I am performing some tests over a 5G Accelerator, ACC200 using DPDK-BBdev. I am
creating custom test-vector files to generate custom load over the ACC200
device. Currently, I am performing the LDPC encoding test through code block
mode. For the same, I have created a following vector file that includes
multiple input and output parameters in following format:
op_type=
RTE_BBDEV_OP_LDPC_ENC
input0=
0x168356b5
input1=
0xb86ea705
output0=
0x77653168,0x49f8607b,0xb28dc29d,0xe52ce65c
output1=
0x0083eb76,0x20397a20,0x5927a0a5,0x6154eabe
basegraph=
2
z_c=
6
q_m=
1
n_filler=
28
n_cb=
300
e=
128
rv_index =
0
code_block_mode =
1
op_flags =
RTE_BBDEV_LDPC_RATE_MATCH
expected_status =
OK
When I execute the test through test-BBdev command:
./test-bbdev.py -e="-l 11 --vfio-vf-token=${UUID} --allow 0000:f7:00.2
--log-level lib.bbdev:debug" -l 4 -v /root/cb_mode_32_128_multi_data.data -c
validation
I face the following error:
== test: validation
dev:0000:f7:00.2, burst size: 32, num ops: 32, op type:

Here I would like understand if there is any wrong configuration that I am
setting or if this flow of mulitple inputs and multiple outputs is unsupported?
Tagging @nicolas.chau...@intel.com<mailto:nicolas.chau...@intel.com>, as I see
a lot of contribution from your end.
Any insights or guidance to help resolve this issue would be highly
appreciated. If you need any more details, please feel free to ask.
Thank you for your time and assistance!
