i40e_init_asq(9)

💖 i40e_init_asq(9) 💖

okay so bestie, welcome to the manual page for i40e_init_asq — it lives in the Kernel API Manual and honestly? it's giving "backstage pass to the Admin Send Queue". let's get into it 🎀

---

✨ NAME ✨

i40e_init_asq — the main initialization routine for ASQ 💅

---

🌸 SYNOPSIS 🌸

int i40e_init_asq (struct i40e_hw *hw );

---

🦋 ARGUMENTS 🦋

• hw — pointer to the hardware structure. that's your hardware bestie, the whole vibe of the thing 🫶

---

💜 DESCRIPTION 💜

okay so this right here is the main initialization routine for the Admin Send Queue. the main character energy is unreal 👑

but before you even think about calling this function, drivers *MUST* set these fields in the hw->aq structure — no cap, this is non-negotiable:

• hw->aq.num_asq_entries
• hw->aq.arq_buf_size

like literally set them first. both of them. that's the whole pregame 🧚

⚠️ and do *NOT* hold the lock when you call this! the memory allocation routines it calls are not going to be atomic context safe, and you will simply not slay if you ignore that 😭
