rte_pmd_cnxk_crypto_qptr_get()

__rte_experimental struct rte_pmd_cnxk_crypto_qptr * rte_pmd_cnxk_crypto_qptr_get	(	uint8_t	dev_id,
		uint16_t	qp_id )

Get queue pointer of a specific queue in a cryptodev.

Parameters

dev_id	Device identifier of cryptodev device.
qp_id	Index of the queue pair.

Returns

• On success, pointer to queue pair structure that would be the input to submit APIs.
• NULL on error.

rte_pmd_cnxk_crypto_submit()

__rte_experimental void rte_pmd_cnxk_crypto_submit	(	struct rte_pmd_cnxk_crypto_qptr *	qptr,
		void *	inst,
		uint16_t	nb_inst )

Submit CPT instruction (cpt_inst_s) to hardware (CPT).

The qp is a pointer obtained from rte_pmd_cnxk_crypto_qp_get. Application should make sure it doesn't overflow the internal hardware queues. It may do so by making sure the inflight packets are not more than the number of descriptors configured.

This API may be called only after the cryptodev and queue pair is configured and is started.

Parameters

qptr	Pointer obtained with rte_pmd_cnxk_crypto_qptr_get.
inst	Pointer to an array of instructions prepared by application.
nb_inst	Number of instructions.

rte_pmd_cnxk_crypto_cptr_flush()

__rte_experimental int rte_pmd_cnxk_crypto_cptr_flush	(	struct rte_pmd_cnxk_crypto_qptr *	qptr,
		struct rte_pmd_cnxk_crypto_cptr *	cptr,
		bool	invalidate )

Flush the CPTR from CPT CTX cache.

This API must be called only after the cryptodev and queue pair is configured and is started.

Parameters

qptr	Pointer obtained with rte_pmd_cnxk_crypto_qptr_get.
cptr	Pointer obtained with rte_pmd_cnxk_crypto_cptr_get or any valid CPTR address that can be used with CPT CTX cache.
invalidate	If true, invalidate the CTX cache entry. If false, flush the CTX cache entry.

Returns

• 0 on success.
• Negative value on error.
  • -EINVAL if the input parameters are invalid.
  • -ENOTSUP if the operation is not supported.
  • -EAGAIN if the operation is not successful.
  • -EFAULT if the operation failed.

rte_pmd_cnxk_crypto_cptr_get()

__rte_experimental struct rte_pmd_cnxk_crypto_cptr * rte_pmd_cnxk_crypto_cptr_get

(

struct rte_pmd_cnxk_crypto_sess *

rte_sess

)

Get the HW CPTR pointer from the rte_crypto/rte_security session.

Parameters

rte_sess

Pointer to the structure holding rte_cryptodev or rte_security session.

Returns

• On success, pointer to the HW CPTR.
• NULL on error.

rte_pmd_cnxk_crypto_cptr_read()

__rte_experimental int rte_pmd_cnxk_crypto_cptr_read	(	struct rte_pmd_cnxk_crypto_qptr *	qptr,
		struct rte_pmd_cnxk_crypto_cptr *	cptr,
		void *	data,
		uint32_t	len )

Read HW context (CPTR).

Parameters

	qptr	Pointer obtained with rte_pmd_cnxk_crypto_qptr_get.
	cptr	Pointer obtained with rte_pmd_cnxk_crypto_cptr_get or any valid CPTR address that can be used with CPT CTX cache.
[out]	data	Destination pointer to copy CPTR context for application.
	len	Length of CPTR context to copy into data parameter.

Returns

• 0 On success.
• Negative value on error.
  • -EINVAL if the input parameters are invalid.
  • -ENOTSUP if the operation is not supported.
  • -EAGAIN if the operation is not successful.
  • -EFAULT if the operation failed.

rte_pmd_cnxk_crypto_cptr_write()

__rte_experimental int rte_pmd_cnxk_crypto_cptr_write	(	struct rte_pmd_cnxk_crypto_qptr *	qptr,
		struct rte_pmd_cnxk_crypto_cptr *	cptr,
		void *	data,
		uint32_t	len )

Write HW context (CPTR).

Parameters

qptr	Pointer obtained with rte_pmd_cnxk_crypto_qptr_get.
cptr	Pointer obtained with rte_pmd_cnxk_crypto_cptr_get or any valid CPTR address that can be used with CPT CTX cache.
data	Source pointer to copy CPTR context from application.
len	Length of CPTR context to copy from data parameter.

Returns

• 0 On success.
• Negative value on error.
  • -EINVAL if the input parameters are invalid.
  • -ENOTSUP if the operation is not supported.
  • -EAGAIN if the operation is not successful.
  • -EFAULT if the operation failed.

rte_pmd_cnxk_crypto_qp_stats_get()

__rte_experimental int rte_pmd_cnxk_crypto_qp_stats_get	(	struct rte_pmd_cnxk_crypto_qptr *	qptr,
		struct rte_pmd_cnxk_crypto_qp_stats *	stats )

Get the HW Queue Pair (LF) stats.

Parameters

	qptr	Pointer obtained with rte_pmd_cnxk_crypto_qptr_get.
[out]	stats	Pointer to the structure where stats will be copied.

Returns

• 0 On success.
• Negative value on error.
  • -EINVAL if the input parameters are invalid.

rte_pmd_cnxk_ae_fpm_table_get()

__rte_experimental const uint64_t * rte_pmd_cnxk_ae_fpm_table_get

(

uint8_t

dev_id

)

Retrieves the addresses of the AE FPM (Finite Precision Math) tables.

This API should be called only after the cryptodev device has been successfully configured. The returned pointer reference memory that is valid as long as the device remains configured and is not destroyed or reconfigured. If the device is reconfigured or destroyed, the memory referenced by the returned pointer becomes invalid and must not be used.

Parameters

dev_id

Device identifier of cryptodev device.

Returns

• On success pointer to the AE FPM table addresses.
• NULL on error.

rte_pmd_cnxk_ae_ec_grp_table_get()

__rte_experimental const struct rte_pmd_cnxk_crypto_ae_ec_group_params ** rte_pmd_cnxk_ae_ec_grp_table_get	(	uint8_t	dev_id,
		uint16_t *	nb_max_entries )

Retrieves the addresses of the AE EC group table.

This API should be called only after the cryptodev device has been successfully configured. The returned pointer reference memory that is valid as long as the device remains configured and is not destroyed or reconfigured. If the device is reconfigured or destroyed, the memory referenced by the returned pointer becomes invalid and must not be used.

Parameters

dev_id	Device identifier of cryptodev device.
nb_max_entries	Pointer to store the maximum number of entries in the EC group table. This value is set by the function to indicate how many entries can be retrieved from the table.

Returns

• On success, pointer to the AE EC group table structure address.
• NULL on error.
