Subject: [PATCH v1] eventdev/crypto: add memzone lookup
Date: Tue, 18 Oct 2022 04:39:26 -0500 [thread overview]
Message-ID: <20221018093926.562384-1-ganapati.kundapura@intel.com> (raw)
Secondary process is not able to call the crypto adapter
api's stats get/reset as crypto adapter memzone memory is not accessible by
secondary process.
Added memzone lookup so that secondary process can call the
crypto adapter api's(stats_get etc)
