init_cmdqs_ctxt(9)

💅 init_cmdqs_ctxt(9) — straight from the Kernel API Manual, bestie 🎀

okay so picture this: it's giving kernel-internals era, and this little function's whole job is to write the cmdq ctxt to HW after init all cmdq ✨ that's the vibe, that's the NAME, periodt.

---

✨ SYNOPSIS ✨

int init_cmdqs_ctxt (struct hinic_hwdev *hwdev , struct hinic_cmdqs
*cmdqs , void __iomem **db_area );

no cap, that's the whole signature. copy it exactly, we don't freestyle in kernel land 🙈

🌸 ARGUMENTS 🌸

• hwdev — the NIC HW device 🫶 like, the actual hardware main character.
• cmdqs — the cmdqs you're writing the ctxts for 💖 these are your command queues, bestie.
• db_area — the db_area for all the cmdqs 👑 every single one, not just your fave.

🦋 DESCRIPTION 🦋

listen, the whole personality is in one line and it ate:

• Return 0 — Success 🎉 slay, we love a clean return.
• negative — Failure 😭 and yes it's negative, so check it, don't just assume it worked.

like literally that's it — the description is the return value. simple queen energy 💅
