hinic_init_sq(9)

✨ hinic_init_sq(9) ✨ — the Kernel API Manual glow-up 🎀

okay so bestie, we're in the Kernel API Manual, section 9, and the whole vibe of this page is literally one function: hinic_init_sq. it's giving "small page, big job" energy ngl 🦋

---

🌸 NAME 🌸

hinic_init_sq — Initialize HW Send Queue 👑

like. it sets up the hardware send queue. that's the whole assignment and she ate 💅

---

⭐ SYNOPSIS ⭐

int hinic_init_sq (struct hinic_sq *sq , struct hinic_hwif *hwif ,
       struct hinic_wq *wq , struct msix_entry *entry , void *ci_addr ,
       dma_addr_t ci_dma_addr , void __iomem *db_base );

so it returns an int, and it takes seven arguments, which is a lot but honestly? main character energy. we love a function who knows what she wants 🫶

---

💖 DESCRIPTION 💖

Return 0 — Success ✨, negative — Failure 😭

that's it, that's the whole plot. zero means we slayed, anything negative means something went sideways. no notes. periodt.

---

🔥 ARGUMENTS 🔥

here's the group chat roll call — every single one, no cap:

• sq — HW Send Queue 👑 (the send queue itself, hardware flavored)
• hwif — HW Interface for accessing HW 🧚 (your little doorway to the hardware)
• wq — Work Queue for the data of the SQ 🍓 (where the SQ's data actually lives)
• entry — msix entry for sq ⚡ (the msix entry that belongs to the sq)
• ci_addr — address for reading the current HW consumer index 🔍
• ci_dma_addr — dma address for reading the current HW consumer index 💫
• db_base — doorbell base address 🔔 (yes, doorbell, we love a literal hardware doorbell)

like, ci_addr and ci_dma_addr are lowkey twins — one is the address, one is the dma address, both for reading that current HW consumer index. don't mix em up bestie 🙈

real talk: this page lives at ./drivers/net/ethernet/huawei/... and it's dated October 2026, version Kernel API Manual. iykyk 💜

and that's the whole page bestie — go init that send queue, you're gonna do amazing 🌸💅✨
