hl_eq_init(9)

💖 hl_eq_init(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the hl_eq_init page and honestly it's giving "small function, big responsibilities" energy. 🎀

---

✨ NAME ✨

hl_eq_init — the main initialization function for an event queue object 🦋

---

✨ SYNOPSIS ✨

int hl_eq_init (struct hl_device *hdev , struct hl_eq *q );

(no cap, that's the whole signature — spaces and all, she's quirky like that 💅)

---

✨ ARGUMENTS ✨

• hdev — pointer to device structure 🖥️ (the device, the main character of this whole operation)
• q — pointer to eq structure 🌸 (the event queue we're about to set up, bless her)

---

✨ DESCRIPTION ✨

So what does she do? Two things, and they're both important:

1. Allocate dma-able memory for the event queue 🔥
2. initialize fields ✨

and that's the whole gig, fr fr.

Returns 0 on success. that's it. that's the return value. 0 = we ate. 👑
