Function Documentation

static void __rte_crypto_op_reset (struct rte_crypto_op * op, enum rte_crypto_op_type type) [inline], [static]

Reset the fields of a crypto operation to their default values.

Parameters:

op The crypto operation to be reset.
type The crypto operation type.

Definition at line 196 of file rte_crypto.h.

static uint16_t __rte_crypto_op_get_priv_data_size (struct rte_mempool * mempool) [inline], [static]

Returns the size of private data allocated with each rte_crypto_op object by the mempool

Parameters:

mempool rte_crypto_op mempool

Returns:

private data size

Definition at line 235 of file rte_crypto.h.

struct rte_mempool* rte_crypto_op_pool_create (const char * name, enum rte_crypto_op_type type, unsigned nb_elts, unsigned cache_size, uint16_t priv_size, int socket_id)

Creates a crypto operation pool

Parameters:

name pool name
type crypto operation type, use RTE_CRYPTO_OP_TYPE_UNDEFINED for a pool which supports all operation types
nb_elts number of elements in pool
cache_size Number of elements to cache on lcore, see rte_mempool_create for further details about cache size
priv_size Size of private data to allocate with each operation
socket_id Socket to allocate memory on

Returns:

  • On success pointer to mempool
  • On failure NULL

static int __rte_crypto_op_raw_bulk_alloc (struct rte_mempool * mempool, enum rte_crypto_op_type type, struct rte_crypto_op ** ops, uint16_t nb_ops) [inline], [static]

Bulk allocate raw element from mempool and return as crypto operations

Parameters:

mempool crypto operation mempool.
type crypto operation type.
ops Array to place allocated crypto operations
nb_ops Number of crypto operations to allocate

Returns:

•
On success returns number of ops allocated

Definition at line 280 of file rte_crypto.h.

static struct rte_crypto_op* rte_crypto_op_alloc (struct rte_mempool * mempool, enum rte_crypto_op_type type) [inline], [static]

Allocate a crypto operation from a mempool with default parameters set

Parameters:

mempool crypto operation mempool
type operation type to allocate

Returns:

  • On success returns a valid rte_crypto_op structure

Definition at line 308 of file rte_crypto.h.

static unsigned rte_crypto_op_bulk_alloc (struct rte_mempool * mempool, enum rte_crypto_op_type type, struct rte_crypto_op ** ops, uint16_t nb_ops) [inline], [static]

Bulk allocate crypto operations from a mempool with default parameters set

Parameters:

mempool crypto operation mempool
type operation type to allocate
ops Array to place allocated crypto operations
nb_ops Number of crypto operations to allocate

Returns:

  • nb_ops if the number of operations requested were allocated.
  • 0 if the requested number of ops are not available. None are allocated in this case.

Definition at line 338 of file rte_crypto.h.

static void* __rte_crypto_op_get_priv_data (struct rte_crypto_op * op, uint32_t size) [inline], [static]

Returns a pointer to the private data of a crypto operation if that operation has enough capacity for requested size.

Parameters:

op crypto operation.
size size of space requested in private data.

Returns:

  • if sufficient space available returns pointer to start of private data
  • if insufficient space returns NULL

Definition at line 368 of file rte_crypto.h.

static void rte_crypto_op_free (struct rte_crypto_op * op) [inline], [static]

free crypto operation structure If operation has been allocate from a rte_mempool, then the operation will be returned to the mempool.

Parameters:

op Pointer to symmetric crypto operation allocated with rte_crypto_op_alloc() If op is NULL, no operation is performed.

Definition at line 398 of file rte_crypto.h.
