hinic_io_init(9)

💖 hinic_io_init — like, the whole origin story 💖

okay so bestie, welcome to the hinic_io_init(9) page — it lives in the Kernel API Manual and it's literally the moment where your IO components get their whole life together ✨ no cap, this is the function that sets things up so the rest of the Huawei hinic driver can actually do stuff.

🌸 NAME 🌸

hinic_io_init — initialize the IO components 🎀

like, all of them. the whole IO situation. she's the main character of setup functions fr fr 💅

---

✨ SYNOPSIS ✨

int hinic_io_init (struct hinic_func_to_io *func_to_io , struct
       hinic_hwif *hwif , u16 max_qps , int num_ceqs , struct msix_entry
       *ceq_msix_entries );

she takes five args and gives you back an int — and yes we will be discussing what that int means in a sec 👀

🦋 ARGUMENTS 🦋

• func_to_io — the func-to-io channel that holds all the IO components 🫶 think of it as the cute little bag where all the IO stuff lives.
• hwif — the HW interface for accessing IO. your backstage pass to the hardware, iykyk 🔑
• max_qps — maximum QPs in HW. the ceiling, the limit, the "that's enough queue pairs for today" number 💀
• num_ceqs — number completion event queues. count 'em, bestie 🧮
• ceq_msix_entries — msix entries for ceqs. the msix vibes that go with those ceqs ✨

---

🎀 DESCRIPTION 🎀

okay so here's the whole description and I'm gonna give it to you exactly as it is, because it's honestly iconic in its minimalism:

Return 0 - Success, negative - Failure

that's it. that's the whole description. zero means slay, negative means it's giving disaster 😭 so like, check your return value, bestie — she's not gonna sugarcoat it for you 💜
