ice_init_sq(9)

💅 ice_init_sq — the manual page, but make it make sense

okay so bestie, welcome to the Kernel API Manual entry for ice_init_sq(9) — yes, that's the section 9 situation, kernel-internals girlie territory 🧚✨

---

✨ NAME ✨

ice_init_sq — the main initialization routine for the Control ATQ 🎀

---

🦋 SYNOPSIS 🦋

int ice_init_sq (struct ice_hw *hw , struct ice_ctl_q_info *cq );

---

🌸 ARGUMENTS 🌸

• hw — pointer to the hardware structure 💜
• cq — pointer to the specific Control queue 🫶

---

🔥 DESCRIPTION 🔥

So this is the main initialization routine for the Control Send Queue. Main character energy, truly 👑

But listen — before you even think about calling this function, the driver *MUST* set these fields in the cq->structure:

• cq->num_sq_entries
• cq->sq_buf_size

That's not a suggestion, bestie, that's a MUST — capital letters, no cap 💀

And do *NOT* hold the lock when you call this, okay? The memory allocation routines it calls are not going to be atomic context safe. So like… put the lock down first. fr fr 🙈
