QAT 4943 in DPDK not supporting SNOW-3G and ZUC

[frog1120]

Hi, 

I'm testing QAT Gen4 4943 VF devices in DPDK23.11 with AES, SNOW-3G and ZUC cipher algorithm.

(As far as I know, QAT devces can support all AES, SNOW-3G and ZUC)

However, when I test with dpdp example application, I found that my QAT 4943 device cannot pass the SNOW-3G and ZUC test suite.

In dpdk23.11 source,  in QAT Gen4 device capability list, SNOW-3G and ZUC are not included.

Gen2 and Gen3 capability list include SNOW-3G and ZUC.  

What happened? Cannot QAT 4943 (Gen4) support SNOW-3G and ZUC?

I run :

dpdk-test -l1 -n1 -a 0000:76:00.1

EAL: Detected CPU lcores: 128
EAL: Detected NUMA nodes: 2
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'PA'

Hi,

QAT Gen4 devices use the driver for QAT Hardware version 2.0, while previous QAT Gen devices uses the QAT Hardware version 1.x. These two drivers support different cipher algorithms. SNOW-3G and ZUC are examples of algorithms that are supported by the QAT Hardware version 1.x driver (used by QAT Gen2 and Gen3) but not by the QAT Hardware version 2.0 driver (used by QAT Gen4). That's the reason why you see these specific algorithms being skipped in the DPDK test.

You can consult the supported algorithms in the QAT Hardware version 2.0 driver here: Cryptographic Services.
