This requires support for attaching\nsessions to specific queue pair. New APIs are introduced to\nattach/detach a session with/from a particular queue pair.\nThese are optional APIs.\n\nApplication can call attach API after creating a session\nand can call detach API before deleting a session.\n\nApplication needs to check if max_nb_sessions_per_qp > 0,\nthen it should call the attach API.\n\nmax_nb_sessions_per_qp = 0 means infinite sessions per qp\n\nSigned-off-by: Akhil Goyal <akhil.goyal@nxp.com>\n---\n lib/librte_cryptodev/rte_cryptodev.c | 41 ++++++++++++++++++++++++++\n lib/librte_cryptodev/rte_cryptodev.h | 27 +++++++++++++++++\n lib/librte_cryptodev/rte_cryptodev_pmd.h | 29 ++++++++++++++++++\n lib/librte_cryptodev/rte_cryptodev_version.map | 2 ++\n 4 files changed, 99 insertions(+)", "diff": "diff --git a/lib/librte_cryptodev/rte_cryptodev.c b/lib/librte_cryptodev/rte_cryptodev.c\nindex 0ac23ed..f1eabd0 100644\n--- a/lib/librte_cryptodev/rte_cryptodev.c\n+++ b/lib/librte_cryptodev/rte_cryptodev.c\n@@ -1393,6 +1393,47 @@ rte_cryptodev_sym_session_create(uint8_t dev_id,\n \treturn sess;\n }\n \n+void\n+rte_cryptodev_queue_pair_attach_sym_session(uint16_t qp_id,\n+\t\tstruct rte_cryptodev_sym_session *sess)\n+{\n+\tstruct rte_cryptodev *dev;\n+\n+\tif (!rte_cryptodev_pmd_is_valid_dev(sess->dev_id)) {\n+\t\tCDEV_LOG_ERR(\"Invalid dev_id=%d\", sess->dev_id);\n+\t\treturn;\n+\t}\n+\n+\tdev = &rte_crypto_devices[sess->dev_id];\n+\n+\tRTE_FUNC_PTR_OR_RET(*dev->dev_ops->qp_attach_session);\n+\tif (dev->dev_ops->qp_attach_session(dev, qp_id, sess->_private)) {\n+\t\tCDEV_LOG_ERR(\"dev_id %d failed to attach qp: %d with session\",\n+\t\t\t\tsess->dev_id, qp_id);\n+\t\treturn;\n+\t}\n+}\n+\n+void\n+rte_cryptodev_queue_pair_detach_sym_session(uint16_t qp_id,\n+\t\tstruct rte_cryptodev_sym_session *sess)\n+{\n+\tstruct rte_cryptodev *dev;\n+\n+\tif (!rte_cryptodev_pmd_is_valid_dev(sess->dev_id)) {\n+\t\tCDEV_LOG_ERR(\"Invalid dev_id=%d\", sess->dev_id);\n+\t\treturn;\n+\t}\n+\n+\tdev = &rte_crypto_devices[sess->dev_id];\n+\n+\tRTE_FUNC_PTR_OR_RET(*dev->dev_ops->qp_detach_session);\n+\tif (dev->dev_ops->qp_detach_session(dev, qp_id, sess->_private)) {\n+\t\tCDEV_LOG_ERR(\"dev_id %d failed to detach qp: %d from session\",\n+\t\t\t\tsess->dev_id, qp_id);\n+\t\treturn;\n+\t}\n+}\n struct rte_cryptodev_sym_session *\n rte_cryptodev_sym_session_free(uint8_t dev_id,\n \t\tstruct rte_cryptodev_sym_session *sess)\ndiff --git a/lib/librte_cryptodev/rte_cryptodev.h b/lib/librte_cryptodev/rte_cryptodev.h\nindex d61a43e..b322bea 100644\n--- a/lib/librte_cryptodev/rte_cryptodev.h\n+++ b/lib/librte_cryptodev/rte_cryptodev.h\n@@ -332,6 +332,9 @@ struct rte_cryptodev_info {\n \tstruct {\n \t\tunsigned max_nb_sessions;\n \t\t/**< Maximum number of sessions supported by device. */\n+\t\tunsigned max_nb_sessions_per_qp;\n+\t\t/**< Maximum number of sessions per queue pair.\n+\t\t * Default 0 for infinite sessions. */\n \t} sym;\n };\n \n@@ -915,6 +918,30 @@ extern struct rte_cryptodev_sym_session *\n rte_cryptodev_sym_session_free(uint8_t dev_id,\n \t\tstruct rte_cryptodev_sym_session *session);\n \n+/**\n+ * Attach queue pair with sym session.\n+ *\n+ * @param\tqp_id\t\tQueue pair to which session will be attached.\n+ * @param\tsession\t\tSession pointer previously allocated by\n+ *\t\t\t\t*rte_cryptodev_sym_session_create*.\n+ *\n+ */\n+extern void\n+rte_cryptodev_queue_pair_attach_sym_session(uint16_t qp_id,\n+\t\tstruct rte_cryptodev_sym_session *session);\n+\n+/**\n+ * Detach queue pair with sym session.\n+ *\n+ * @param\tqp_id\t\tQueue pair to which session is attached.\n+ * @param\tsession\t\tSession pointer previously allocated by\n+ *\t\t\t\t*rte_cryptodev_sym_session_create*.\n+ *\n+ */\n+extern void\n+rte_cryptodev_queue_pair_detach_sym_session(uint16_t qp_id,\n+\t\tstruct rte_cryptodev_sym_session *session);\n+\n \n #ifdef __cplusplus\n }\ndiff --git a/lib/librte_cryptodev/rte_cryptodev_pmd.h b/lib/librte_cryptodev/rte_cryptodev_pmd.h\nindex 1a417e2..df92817 100644\n--- a/lib/librte_cryptodev/rte_cryptodev_pmd.h\n+++ b/lib/librte_cryptodev/rte_cryptodev_pmd.h\n@@ -381,6 +381,31 @@ typedef void * (*cryptodev_sym_configure_session_t)(struct rte_cryptodev *dev,\n typedef void (*cryptodev_sym_free_session_t)(struct rte_cryptodev *dev,\n \t\tvoid *session_private);\n \n+/**\n+ * Optional API for drivers to attach sessions with queue pair.\n+ * @param\tdev\t\tCrypto device pointer\n+ * @param\tqp_id\t\tqueue pair id for attaching session\n+ * @param\tpriv_sess Pointer to cryptodev's private session structure\n+ * @return\n+ * -
