i40e_acquire_nvm(9)

✨ i40e_acquire_nvm(9) ✨

ok so this is a page from the Kernel API Manual — yes bestie, the kernel has a manual too, and it's lowkey iconic 💅

---

🌸 NAME 🌸

i40e_acquire_nvm — the generic way to ask for the NVM ownership, basically sliding into the NVM's DMs and asking "hey, can I have the keys for a sec?" 🔑

---

🦋 SYNOPSIS 🦋

int i40e_acquire_nvm (struct i40e_hw *hw , enum
i40e_aq_resource_access_type access );

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. the actual hardware vibes live in here 🫶
• access — the NVM access type, and it's giving read or write. choose your fighter ✨

---

💖 DESCRIPTION 💖

so this function will request NVM ownership for reading, and it does it via the proper Admin Command. that's the whole thing. not me writing a whole manpage for a one-liner, but honestly? she earned it 👑

ngl, the description says for reading even though access can be read or write — that's literally what the page says, so I'm not gonna invent lore about it 🙈
