Yes, I see.

But for decryption, we should prepare the correct ci= pher data, right? Or that test does not make any sense.

Hi Suanming,

 

The pmd-cycle-count mode is for counting the cycles = for enqueue and dequeue.

It does not matter what is the content of the packet= , as we are not validating the content

after dequeue of the packet. PMD/Hw will assume it a= s plain/encrypted payload and

will process it as per the session attached.

Hence, doing memcpy to mbuf is not required.

Akhil

Hi Guys,

 

Sorry for the inconvenience.

I have one small question with pmd-cycle-count test = in test-crypto-perf application.

As in pmd-cycle-count run code, I don’t see th= e cperf_mbuf_set() function is called to fill the test data.

So for decryption, I assume it will always fails. Fe= el like pmd-cycle-count test does not expect to support decryption. Or is i= t a bug?

 

I have no idea with the application design backgroun= d, is it expected?

 

Thanks,
