Enumeration Type Documentation

enum rte_bbdev_op_td_flag_bitmasks

Flags for turbo decoder operation and capability structure

Enumerator:

RTE_BBDEV_TURBO_SUBBLOCK_DEINTERLEAVE	If sub block de-interleaving is to be performed. To use CRC Type 24B (otherwise use CRC Type 24A).
RTE_BBDEV_TURBO_CRC_TYPE_24B	If turbo equalization is to be performed.
RTE_BBDEV_TURBO_EQUALIZER	If set, saturate soft output to +/-127
RTE_BBDEV_TURBO_SOFT_OUT_SATURATE	Set to 1 to start iteration from even, else odd; one iteration = max_iteration + 0.5
RTE_BBDEV_TURBO_HALF_ITERATION_EVEN	If 0, TD stops after CRC matches; else if 1, runs to end of next odd iteration after CRC matches
RTE_BBDEV_TURBO_CONTINUE_CRC_MATCH	Set if soft output is required to be output
RTE_BBDEV_TURBO_SOFT_OUTPUT	Set to enable early termination mode
RTE_BBDEV_TURBO_EARLY_TERMINATION	Set if a device supports decoder dequeue interrupts
RTE_BBDEV_TURBO_DEC_INTERRUPTS	Set if positive LLR encoded input is supported. Positive LLR value represents the level of confidence for bit '1', and vice versa for bit '0'. This is mutually exclusive with RTE_BBDEV_TURBO_NEG_LLR_1_BIT_IN when used to formalize the input data format.
RTE_BBDEV_TURBO_POS_LLR_1_BIT_IN	Set if negative LLR encoded input is supported. Negative LLR value represents the level of confidence for bit '1', and vice versa for bit '0'. This is mutually exclusive with RTE_BBDEV_TURBO_POS_LLR_1_BIT_IN when used to formalize the input data format.
RTE_BBDEV_TURBO_NEG_LLR_1_BIT_IN	Set if positive LLR soft output is supported. Positive LLR value represents the level of confidence for bit '1', and vice versa for bit '0'. This is mutually exclusive with RTE_BBDEV_TURBO_NEG_LLR_1_BIT_SOFT_OUT when used to formalize the input data format.
RTE_BBDEV_TURBO_POS_LLR_1_BIT_SOFT_OUT	Set if negative LLR soft output is supported. Negative LLR value represents the level of confidence for bit '1', and vice versa for bit '0'. This is mutually exclusive with RTE_BBDEV_TURBO_POS_LLR_1_BIT_SOFT_OUT when used to formalize the input data format.
RTE_BBDEV_TURBO_NEG_LLR_1_BIT_SOFT_OUT	Set if driver supports flexible parallel MAP engine decoding. If not supported, num_maps (number of MAP engines) argument is unusable.
RTE_BBDEV_TURBO_MAP_DEC	Set if a device supports scatter-gather functionality
RTE_BBDEV_TURBO_DEC_SCATTER_GATHER	Set to keep CRC24B bits appended while decoding. Only usable when decoding Transport Blocks (code_block_mode = 0).

enum rte_bbdev_op_te_flag_bitmasks

Flags for turbo encoder operation and capability structure

Enumerator:

RTE_BBDEV_TURBO_RV_INDEX_BYPASS	Ignore rv_index and set K0 = 0 If rate matching is to be performed
RTE_BBDEV_TURBO_RATE_MATCH	This bit must be set to enable CRC-24B generation
RTE_BBDEV_TURBO_CRC_24B_ATTACH	This bit must be set to enable CRC-24A generation
RTE_BBDEV_TURBO_CRC_24A_ATTACH	Set if a device supports encoder dequeue interrupts
RTE_BBDEV_TURBO_ENC_INTERRUPTS	Set if a device supports scatter-gather functionality

Definition at line 113 of file rte_bbdev_op.h.

enum rte_bbdev_op_type

Different operation types supported by the device

Enumerator:

RTE_BBDEV_OP_NONE	Dummy operation that does nothing
RTE_BBDEV_OP_TURBO_DEC	Turbo decode
RTE_BBDEV_OP_TURBO_ENC	Turbo encode
RTE_BBDEV_OP_TYPE_COUNT	Count of different op types

Function Documentation

const char* rte_bbdev_op_type_str

(

enum rte_bbdev_op_type

op_type

)

Converts queue operation type from enum to string

Parameters

op_type

Operation type as enum

Returns

Operation type as string or NULL if op_type is invalid

struct rte_mempool* rte_bbdev_op_pool_create ( const char *  name, enum rte_bbdev_op_type  type, unsigned int  num_elements, unsigned int  cache_size, int  socket_id  )

read

Creates a bbdev operation mempool

Parameters

name	Pool name.
type	Operation type, use RTE_BBDEV_OP_NONE for a pool which supports all operation types.
num_elements	Number of elements in the pool.
cache_size	Number of elements to cache on an lcore, see rte_mempool_create() for further details about cache size.
socket_id	Socket to allocate memory on.

Returns

• Pointer to a mempool on success,
• NULL pointer on failure.

Examples:

static int rte_bbdev_enc_op_alloc_bulk ( struct rte_mempool *  mempool, struct rte_bbdev_enc_op **  ops, uint16_t  num_ops  )

inlinestatic

Bulk allocate encode operations from a mempool with parameter defaults reset.

Parameters

mempool	Operation mempool, created by rte_bbdev_op_pool_create().
ops	Output array to place allocated operations
num_ops	Number of operations to allocate

Returns

• 0 on success
• EINVAL if invalid mempool is provided
