Function Documentation

rte_pmd_cnxk_crypto_qptr_get()

void* 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

Pointer to queue pair structure that would be the input to submit APIs.

rte_pmd_cnxk_crypto_submit()

void rte_pmd_cnxk_crypto_submit	(	void *	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.
