Detailed Description

RTE Cryptodev Scheduler Device

The RTE Cryptodev Scheduler Device allows the aggregation of multiple worker Cryptodevs into a single logical crypto device, and the scheduling the crypto operations to the workers based on the mode of the specified mode of operation specified and supported. This implementation supports 3 modes of operation: round robin, packet-size based, and fail-over.

rte_cryptodev_scheduler_load_user_scheduler()

int rte_cryptodev_scheduler_load_user_scheduler	(	uint8_t	scheduler_id,
		struct rte_cryptodev_scheduler *	scheduler
	)

Load a user defined scheduler

Parameters

scheduler_id	The target scheduler device ID
scheduler	Pointer to the user defined scheduler

Returns

• 0 if the scheduler is successfully loaded
• -ENOTSUP if the operation is not supported.
• -EBUSY if device is started.
• -EINVAL if input values are invalid.

rte_cryptodev_scheduler_worker_attach()
