rte_bbdev_op_ldpc_enc(3)

📦 version 26.03, in nixos 26.05, nixpkgs unstable

🫶 NAME 🫶

rte_bbdev_op_ldpc_enc — okay so bestie, this is the Library Functions Manual page for the LDPC encode operation struct, and it's literally gonna walk you through every field. No cap. 💅

✨ 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 basegraph
  • uint16_t z_c
  • uint16_t n_cb
  • uint8_t q_m
  • uint16_t n_filler
  • uint8_t code_block_mode

🌈 Detailed Description 🌈

So this is the operation structure for LDPC encode. An operation can be performed on one CB at a time — that's "CB-mode". An operation can also be performed on one or multiple CBs that logically belong to a TB — that's "TB-mode". Both vibes are valid. ✨

The input data is the CB or TB input to the decoder.

The output data is the ratematched CB or TB data, or the output after bit-selection if RTE_BBDEV_LDPC_INTERLEAVER_BYPASS is set.

The output mbuf data structure is expected to be allocated by the application with enough room for the output data. Like, pls give it space to breathe. 🫶
