static uint16_t rte_cryptodev_dequeue_burst ( uint8_t  dev_id,
uint16_t  qp_id,
struct rte_crypto_op **  ops,
uint16_t  nb_ops 
)
inlinestatic

Dequeue a burst of processed crypto operations from a queue on the crypto device. The dequeued operation are stored in rte_crypto_op structures whose pointers are supplied in the ops array.

The rte_cryptodev_dequeue_burst() function returns the number of ops actually dequeued, which is the number of rte_crypto_op data structures effectively supplied into the ops array.

A return value equal to nb_ops indicates that the queue contained at least nb_ops operations, and this is likely to signify that other processed operations remain in the devices output queue. Applications implementing a "retrieve as many processed operations as possible" policy can check this specific case and keep invoking the rte_cryptodev_dequeue_burst() function until a value less than nb_ops is returned.

The rte_cryptodev_dequeue_burst() function does not provide any error notification to avoid the corresponding overhead.

Parameters
dev_idThe symmetric crypto device identifier
qp_idThe index of the queue pair from which to retrieve processed packets. The value must be in the range [0, nb_queue_pair - 1] previously supplied to rte_cryptodev_configure().
opsThe address of an array of pointers to rte_crypto_op structures that must be large enough to store nb_ops pointers in it.
nb_opsThe maximum number of operations to dequeue.
Returns
  • The number of operations actually dequeued, which is the number of pointers to rte_crypto_op structures effectively supplied to the ops array.
Examples:
examples/fips_validation/fips_dev_self_test.c, examples/fips_validation/main.c, examples/ipsec-secgw/ipsec.c, examples/ipsec-secgw/ipsec_process.c, examples/l2fwd-crypto/main.c, and examples/vhost_crypto/main.c.

static uint16_t rte_cryptodev_enqueue_burst ( uint8_t  dev_id,
uint16_t  qp_id,
struct rte_crypto_op **  ops,
uint16_t  nb_ops 
)
inlinestatic

Enqueue a burst of operations for processing on a crypto device.

The rte_cryptodev_enqueue_burst() function is invoked to place crypto operations on the queue qp_id of the device designated by its dev_id.

The nb_ops parameter is the number of operations to process which are supplied in the ops array of rte_crypto_op structures.

The rte_cryptodev_enqueue_burst() function returns the number of operations it actually enqueued for processing. A return value equal to nb_ops means that all packets have been enqueued.

Parameters
dev_idThe identifier of the device.
qp_idThe index of the queue pair which packets are to be enqueued for processing. The value must be in the range [0, nb_queue_pairs - 1] previously supplied to rte_cryptodev_configure.
opsThe address of an array of nb_ops pointers to rte_crypto_op structures which contain the crypto operations to be processed.
nb_opsThe number of operations to process.
Returns
The number of operations actually enqueued on the crypto device. The return value can be less than the value of the nb_ops parameter when the crypto devices queue is full or if invalid parameters are specified in a rte_crypto_op.

struct rte_crypto_raw_dp_ctx ctx,
enum rte_crypto_op_sess_type  sess_type,
union rte_cryptodev_session_ctx  session_ctx,
uint8_t  is_update 
)

Configure raw data-path context data.

NOTE: After the context data is configured, the user should call rte_cryptodev_raw_attach_session() before using it in rte_cryptodev_raw_enqueue/dequeue function call.

Parameters
dev_idThe device identifier.
qp_idThe index of the queue pair from which to retrieve processed packets. The value must be in the range [0, nb_queue_pair - 1] previously supplied to rte_cryptodev_configure().
ctxThe raw data-path context data.
sess_typesession type.
session_ctxSession context data.
is_updateSet 0 if it is to initialize the ctx. Set 1 if ctx is initialized and only to update session context data.
Returns
  • On success return 0.
  • On failure return negative integer.

struct rte_crypto_sym_vec vec,
union rte_crypto_sym_ofs  ofs,
void **  user_data,
int *  enqueue_status 
)

Enqueue a vectorized operation descriptor into the device queue but the driver may or may not start processing until rte_cryptodev_raw_enqueue_done() is called.

Parameters
ctxThe initialized raw data-path context data.
vecVectorized operation descriptor.
ofsStart and stop offsets for auth and cipher operations.
user_dataThe array of user data for dequeue later.
enqueue_statusDriver written value to specify the enqueue status. Possible values:
  • 1: The number of operations returned are enqueued successfully.
  • 0: The number of operations returned are cached into the queue but are not processed until rte_cryptodev_raw_enqueue_done() is called.
  • negative integer: Error occurred.
Returns
  • The number of operations in the descriptor successfully enqueued or cached into the queue but not enqueued yet, depends on the "enqueue_status" value.

)
static

Enqueue single raw data vector into the device queue but the driver may or may not start processing until rte_cryptodev_raw_enqueue_done() is called.

Parameters
ctxThe initialized raw data-path context data.
data_vecThe buffer data vector.
n_data_vecsNumber of buffer data vectors.
ofsStart and stop offsets for auth and cipher operations.
ivIV virtual and IOVA addresses
digestdigest virtual and IOVA addresses
aad_or_auth_ivAAD or auth IV virtual and IOVA addresses, depends on the algorithm used.
user_dataThe user data.
Returns
  • 1: The data vector is enqueued successfully.
  • 0: The data vector is cached into the queue but is not processed until rte_cryptodev_raw_enqueue_done() is called.
  • negative integer: failure.

__rte_experimental int rte_cryptodev_raw_enqueue_done ( struct rte_crypto_raw_dp_ctx ctx,
uint32_t  n 
)

Start processing all enqueued operations from last rte_cryptodev_configure_raw_dp_ctx() call.

Parameters
ctxThe initialized raw data-path context data.
nThe number of operations cached.
Returns
  • On success return 0.
  • On failure return negative integer.

void **  out_user_data,
uint8_t  is_user_data_array,
uint32_t *  n_success,
int *  dequeue_status 
)

Dequeue a burst of symmetric crypto processing.

Parameters
ctxThe initialized raw data-path context data.
get_dequeue_countUser provided callback function to obtain dequeue operation count.
post_dequeueUser provided callback function to post-process a dequeued operation.
out_user_dataUser data pointer array to be retrieve from device queue. In case of is_user_data_array is set there should be enough room to store all user data.
is_user_data_arraySet 1 if every dequeued user data will be written into out_user_data array. Set 0 if only the first user data will be written into out_user_data array.
n_successDriver written value to specific the total successful operations count.
dequeue_statusDriver written value to specify the dequeue status. Possible values:
  • 1: Successfully dequeued the number of operations returned. The user data previously set during enqueue is stored in the "out_user_data".
  • 0: The number of operations returned are completed and the user data is stored in the "out_user_data", but they are not freed from the queue until rte_cryptodev_raw_dequeue_done() is called.
  • negative integer: Error occurred.
Returns
  • The number of operations dequeued or completed but not freed from the queue, depends on "dequeue_status" value.
static __rte_experimental __rte_always_inline void* rte_cryptodev_raw_dequeue ( struct rte_crypto_raw_dp_ctx ctx,
int *  dequeue_status,
enum rte_crypto_op_status op_status 
)
static

Dequeue a symmetric crypto processing.

Parameters
ctxThe initialized raw data-path context data.
dequeue_statusDriver written value to specify the dequeue status. Possible values:
  • 1: Successfully dequeued a operation. The user data is returned.
  • 0: The first operation in the queue is completed and the user data previously set during enqueue is returned, but it is not freed from the queue until rte_cryptodev_raw_dequeue_done() is called.
  • negative integer: Error occurred.
op_statusDriver written value to specify operation status.
Returns
  • The user data pointer retrieved from device queue or NULL if no operation is ready for dequeue.

nThe number of operations.
Returns
  • On success return 0.
  • On failure return negative integer.
