<p class="MsoNormal">Thanks Akhil.<o:p></o:p></p>
<p class="MsoNormal">Yes, I see.<o:p></o:p></p>
<p class="MsoNormal">But for decryption, we should prepare the correct cipher data, right? Or that test does not make any sense.<o:p></o:p></p>

<p class="MsoNormal">Hi Suanming,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The pmd-cycle-count mode is for counting the cycles for enqueue and dequeue.<o:p></o:p></p>
<p class="MsoNormal">It does not matter what is the content of the packet, as we are not validating the content<o:p></o:p></p>
<p class="MsoNormal">after dequeue of the packet. PMD/Hw will assume it as plain/encrypted payload and<o:p></o:p></p>
<p class="MsoNormal">will process it as per the session attached.<o:p></o:p></p>
<p class="MsoNormal">Hence, doing memcpy to mbuf is not required.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>

<p class="MsoNormal">Hi Guys,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Sorry for the inconvenience.<o:p></o:p></p>
<p class="MsoNormal">I have one small question with pmd-cycle-count test in test-crypto-perf application.<o:p></o:p></p>
<p class="MsoNormal">As in pmd-cycle-count run code, I don’t see the cperf_mbuf_set() function is called to fill the test data.<o:p></o:p></p>
<p class="MsoNormal">So for decryption, I assume it will always fails. Feel like pmd-cycle-count test does not expect to support decryption. Or is it a bug?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have no idea with the application design background, is it expected?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
