STRUCT IWL_TRANS_RXQ_DMA_DATA(9)

✨ struct iwl_trans_rxq_dma_data — RX queue DMA data ✨

okay so this is a page from the Kernel API Manual, and bestie, it's a lil struct that holds all the DMA addresses for an RX queue 💅 it's giving "small but essential" energy, fr fr.

---

🌸 SYNOPSIS 🌸

like, here's the whole shape of it, no cap:

struct iwl_trans_rxq_dma_data {
    u64 fr_bd_cb;
    u32 fr_bd_wid;
    u64 urbd_stts_wrptr;
    u64 ur_bd_cb;
 };

that's it. four fields. main character energy in miniature 👑

---

🦋 Members 🦋

• fr_bd_cb — the DMA address of the free BD cyclic buffer 💖
• fr_bd_wid — the initial write index of the free BD cyclic buffer (yes, initial — that detail matters, don't @ me) ✨
• urbd_stts_wrptr — the DMA address of urbd_stts_wrptr 🎀 (yes bestie, the description is literally the field name, I don't make the rules)
• ur_bd_cb — the DMA address of the used BD cyclic buffer 🌈

okay this list is LONG, like a group chat where everyone's typing at once 😭 but here's the whole crew, exactly as listed:

like, the whole transport-layer friend group showed up 🫶 go read 'em if you wanna actually understand where this lil struct lives, iykyk 💜

ngl the "Transport layer - what is it ?(9)" title is sending me 💀 but it's a real page and it's in the list, so it stays.

that's the whole vibe check bestie, go forth and be iconic with your RX queue DMA data ⭐
