hinic_hwdev_hw_ci_addr_set(9)

👑 hinic_hwdev_hw_ci_addr_set — from the Kernel API Manual, bestie

Okay so picture this: you're in the hinic driver, you've got a send queue, and the hardware needs to know where your consumer index lives and how it should behave. That's this function. It's hinic_hwdev_hw_ci_addr_set, and it's lowkey the glow-up moment for your SQ's ci address. 💅

✨ NAME ✨

hinic_hwdev_hw_ci_addr_set — sets the cons idx addr and attributes in HW for sq. That's it, that's the whole job, and she does it slayfully. 🎀

🦋 SYNOPSIS 🦋

int hinic_hwdev_hw_ci_addr_set (struct hinic_hwdev *hwdev , struct
       hinic_sq *sq , u8 pending_limit , u8 coalesc_timer );

Like, four things in, one int out. Iconic signature honestly.

🌸 ARGUMENTS 🌸

• hwdev — the NIC HW device. Your main character. The whole NIC. 🫶
• sq — the send queue. The one getting its ci address set. Go off queen.
• pending_limit — the maximum pending update ci events, and ngl the unit is 8. Yes, 8. Not 1, not 8 bytes, just… unit 8. Periodt. 💀
• coalesc_timer — the coalesc period for update ci, and this one's unit is 8 us. Coalescing! Timing! Elegance! ⏱️

---

💖 DESCRIPTION 💖

So what does it actually return, you ask? Glad you did:

• Return 0 — Success ✨ (the good ending)
• negative — Failure 😭 (the bad ending, and yes it's literally just "negative", that's all the docs give us, iykyk)

Okay bestie real talk — the original page is honest-to-god just "Return 0 - Success, negative - Failure" for the description. I'm not out here inventing lore. That's all she gave us. 🙈
