Hi All,
Context: Using dpdk + vpp for telecom network user plane processing
Desired: want to use dpdk crypto-dev scheduler to have 2 cores dedicated
for crypto operations
Issue: crypto devices of different types (AES_MB & AES_GCM) are not
supported concurrently.
Query: Have anyone used crypto scheduler and able to support multiple
crypto device types?
Details:
We want to use 4 cores in total for user plane processing with following
deployment
Core-1: vpp worker thread - downlink
Core-2 : vpp worker thread - uplink
Core-3 : crypto-slave-1 (Cipher: aes-cbc-128)
Core-4 : crypto-slave-2 (Cipher: aes-gcm-128)

Query - Detail : with above log output, we see crypto-slaves aesni_mb_1 &
aesni_gcm_1 deployed on both worker threads but from Test Results we see
following -
AES Traffic - works through crypto scehdular
GCM Traffic - does not work. (Error - dpdk-esp-decrypt Failed to
get crypto session)
Can someone please help to understand this behavior / suggest if any
approach worked for you to support multiple crypto algorithms?
Thanks in advance
Best Regads,
Jitendra
