test_aes_gcm.data file

dpdk-test-crypto-perf got stuck when using openssl driver with multiple segments.


To repro the issue, follow the steps below:

* To run the app, use the following command:

/download/dpdk/install/bin/dpdk-test-crypto-perf -c 0x7fff --vdev crypto_openssl,max_nb_queue_pairs=14 --  --ptest pmd-cyclecount --aead-op encrypt --optype aead --aead-algo aes-gcm --test-file /tmp/test_aes_gcm.data --test-name gcm --total-ops 837134 --aead-key-sz 32 --aead-iv-sz 12 --aead-aad-sz 334 --buffer-sz 256 --burst-sz 32 --digest-sz 16 --segment-sz 32 --devtype crypto_openssl --silent --csv-friendly

startup log:


EAL: Detected CPU lcores: 16
EAL: Detected NUMA nodes: 1
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'PA'
CRYPTODEV: Creating cryptodev crypto_openssl
CRYPTODEV: Initialisation parameters - name: crypto_openssl,socket id: 0, max queue pairs: 14
Allocated pool "sess_mp_0" on socket 0

and the app got stuck.

 

While for mlx driver:

app command:

/download/dpdk/install/bin/dpdk-test-crypto-perf -c 0x7fff -a 0000:03:00.0,class=crypto,algo=1 --  --ptest pmd-cyclecount --aead-op encrypt --optype aead --aead-algo aes-gcm --test-file /tmp/test_aes_gcm.data --test-name gcm --total-ops 837134 --aead-key-sz 32 --aead-iv-sz 12 --aead-aad-sz 334 --buffer-sz 256 --burst-sz 32 --digest-sz 16 --segment-sz 32 --devtype mlx5_pci --silent --csv-friendly

and it works fine when using a single segment with openssl driver:

app command:

/download/dpdk/install/bin/dpdk-test-crypto-perf -c 0x7fff --vdev crypto_openssl,max_nb_queue_pairs=14 --  --ptest pmd-cyclecount --aead-op encrypt --optype aead --aead-algo aes-gcm --test-file /tmp/test_aes_gcm.data --test-name gcm --total-ops 837134 --aead-key-sz 32 --aead-iv-sz 12 --aead-aad-sz 334 --buffer-sz 256 --burst-sz 32 --digest-sz 16 --segment-sz 272 --devtype crypto_openssl --silent --csv-friendly--silent
