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.

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.

Attach a crypto device to the scheduler

Parameters

scheduler_id The target scheduler device ID
worker_id Crypto device ID to be attached

Returns

  • 0 if the worker is attached.
  • -ENOTSUP if the operation is not supported.
  • -EBUSY if device is started.
  • -ENOMEM if the scheduler's worker list is full.

Detach a crypto device from the scheduler

Parameters

scheduler_id The target scheduler device ID
worker_id Crypto device ID to be detached

Returns

  • 0 if the worker is detached.
  • -ENOTSUP if the operation is not supported.
  • -EBUSY if device is started.

Set the scheduling mode

Parameters

scheduler_id The target scheduler device ID
mode The scheduling mode

Returns

  • 0 if the mode is set.
  • -ENOTSUP if the operation is not supported.
  • -EBUSY if device is started.

enum rte_cryptodev_scheduler_mode rte_cryptodev_scheduler_mode_get (uint8_t scheduler_id)

Get the current scheduling mode

Parameters

scheduler_id The target scheduler device ID

Returns

mode
  • non-negative enumerate value: the scheduling mode
  • -ENOTSUP if the operation is not supported.

Set the crypto ops reordering feature on/off

Parameters

scheduler_id The target scheduler device ID
enable_reorder Set the crypto op reordering feature
  • 0: disable reordering
  • 1: enable reordering

Returns

  • 0 if the ordering is set.
  • -ENOTSUP if the operation is not supported.
  • -EBUSY if device is started.

Get the current crypto ops reordering feature

Parameters

scheduler_id The target scheduler device ID

Returns

  • 0 if reordering is disabled
  • 1 if reordering is enabled
  • -ENOTSUP if the operation is not supported.

Get the attached workers' count and/or ID

Parameters

scheduler_id The target scheduler device ID
workers If successful, the function will write back all workers' device IDs to it. This parameter will either be an uint8_t array of RTE_CRYPTODEV_SCHEDULER_MAX_NB_WORKERS elements or NULL.

Returns

  • non-negative number: the number of workers attached
  • -ENOTSUP if the operation is not supported.

Set the mode specific option

Parameters

scheduler_id The target scheduler device ID
option_type The option type enumerate
option The specific mode's option structure

Returns

  • 0 if successful
  • negative integer if otherwise.

Set the mode specific option

Parameters

scheduler_id The target scheduler device ID
option_type The option type enumerate
option If successful, the function will write back the current

Returns

  • 0 if successful
  • negative integer if otherwise.
