Hi Akhil, This isn’t what our concern was – our concern was rte_cryptodev_close() may not remove the memory complete as rte_cryptodev_pmd_destroy() did. Our research result towards this was if the PMD could act more throughout to make rte_cryptodev_close() working same as rte_cryptodev_pmd_destroy().
What Paul’s concern is valid: We DO NOT have a way to release a queue pair manually anymore, and releasing queue pair to me should not be blocked from public API access. To resolve this problem we should have a public queue_pair_release() function in the cryptodev. If you are ok I can send a patch for 21.11 right away.

We’d do so by calling the function pointer queue_pair_release() which I believe is the prescribed way to do this. The DPDK change in question is here: https://github.com/DPDK/dpdk/commit/af668035f7f492424b2e199f155690815944a8ca<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_DPDK_dpdk_commit_af668035f7f492424b2e199f155690815944a8ca&d=DwMF-g&c=nKjWec2b6R0mOyPaz7xtfQ&r=DnL7Si2wl_PRwpZ9TWey3eu68gBzn7DkPwuqhd6WNyo&m=JtjV1tR2S7GKiUDbCzH0F3Eb5a0srzYbypWQ7frSYlM&s=KPcZHMXJD19T_7amxWdYShvis2l7nWAnfs-nJ85FVto&e=> Question: Is there another way for us to release this memory? I’ve looked through the public API and nothing stands out. Thanks Paul
