init_eq(9)

💅 init_eq — the "wake up, Event Queue!" moment

okay so this is init_eq from the Kernel API Manual, section 9. It's the lil' glow-up ritual where an Event Queue gets all its stuff set up so it can actually do its job. bestie, think of it as the EQ's first day of school and you're the one packing its backpack 🎒✨

---

🌸 SYNOPSIS 🌸

int init_eq (struct hinic_eq *eq , struct hinic_hwif *hwif , enum
hinic_eq_type type , int q_id , u32 q_len , u32 page_size , struct
msix_entry entry );

seven lil' arguments, no cap. let's meet them 🫶

---

🎀 ARGUMENTS 🎀

• eq — the event queue itself, the main character of this whole function 💅
• hwif — the HW interface of a PCI function device (the hardware BFF it calls on)
• type — the type of the event queue, aeq or ceq. pick your fighter 🥊
• q_id — Queue id number, its little name tag 🏷️
• q_len — the number of EQ elements, aka how many lil' guys fit inside
• page_size — the page size of the pages in the event queue (yes, pages, in a queue, slay geometry)
• entry — the msix entry associated with the event queue 🔔

✨ DESCRIPTION ✨

the return vibes are, and I quote the lore:

Return 0 - Success, Negative - Failure

so like, 0? iconic, we ate. negative? not the vibe, something went wrong bestie 😭
