STRUCT IWL_BC_TBL_ENTRY(9)

🌸 struct iwl_bc_tbl_entry(9) 🌸

okay bestie, welcome to the manual page for struct iwl_bc_tbl_entry, a kernel API manual situation, section 9, and honestly? it's giving "tiny struct, big responsibilities" energy. 💅

---

✨ NAME ✨

struct iwl_bc_tbl_entry — the scheduler byte count table entry base physical address, provided by SCD_DRAM_BASE_ADDR. For devices up to 22000:

yes, that trailing colon is literally part of the original, we do NOT edit the source material here, we respect the source material 🫶

---

🎀 SYNOPSIS 🎀

struct iwl_bc_tbl_entry {
    __le16 tfd_offset;
 };

that's it. that's the whole struct. one (1) member. a singular little guy. main character energy from a single __le16, we love to see it. ⭐

🦋 Members 🦋

• tfd_offset — okay so this one field is doing double duty depending on which era of hardware you're on, and the bit layout is a lot, so buckle up:
  • For devices up to 22000: bits 0-12 are the tx command byte count, and bits 12-16 are the station index. 😭
  • For 22000 and on: bits 0-12 are the tx command byte count, bits 12-13 are the number of 64 byte chunks, and bits 14-16 are reserved. 🧚

ngl, those ranges overlap, and we are simply reporting them exactly as written — not me "fixing" the numbers, that would be a crime, iykyk. 🙈
