# rte\_bbdev\_op\_turbo\_enc(3)

## NAME

rte\_bbdev\_op\_turbo\_enc

## SYNOPSIS

`#include <rte_bbdev_op.h>`

### Data Fields

struct **rte\_bbdev\_op\_data** **input**\
 struct **rte\_bbdev\_op\_data** **output**\
 uint32\_t **op\_flags**\
 uint8\_t **rv\_index**\
 uint8\_t **code\_block\_mode**\

## Detailed Description

Operation structure for Turbo encode. An operation can be performed on one CB at a time 'CB-mode'. An operation can pbe erformd on one or multiple CBs that logically belong to one TB 'TB-mode'.

In CB-mode, CRC24A/B is an optional operation. K size parameter is not affected by CRC24A/B inclusion, this only affects the inbound mbuf data length. Not all BBDEV PMDs are capable of CRC24A/B calculation. Flags RTE\_BBDEV\_TURBO\_CRC\_24A\_ATTACH and RTE\_BBDEV\_TURBO\_CRC\_24B\_ATTACH informs the application with relevant capability. These flags can be set in the op\_flags parameter to indicate BBDEV to calculate and append CRC24A to CB before going forward with Turbo encoding.

In TB-mode, CRC24A is assumed to be pre-calculated and appended to the inbound TB mbuf data buffer.

The output mbuf data structure is expected to be allocated by the application with enough room for the output data.
