i40e_nvmupd_state_init(9)

💅 i40e_nvmupd_state_init(9) — from the Kernel API Manual, bestie

okay so bestie, welcome to the group chat where we talk about kernel API manual pages. this one is i40e_nvmupd_state_init, and honestly? it's giving "the bouncer at the door of the Init state" energy. let's get into it ✨

---

🎀 NAME 🎀

i40e_nvmupd_state_init — she handles the NVM update state Init. that's the whole vibe. no cap. 🦋

---

✨ SYNOPSIS ✨

int i40e_nvmupd_state_init (struct i40e_hw *hw , struct i40e_nvm_access
*cmd , u8 *bytes , int *perrno );

that's her signature, periodt. four args, returns int, absolutely iconic of her. 💅

---

🧚 ARGUMENTS 🧚

• hw — pointer to hardware structure 👑 (yes, THE hardware structure, main character energy fr fr)
• cmd — pointer to the nvm update command buffer 📨
• bytes — pointer to the data buffer 🍓
• perrno — pointer to the return error code 🚨 (she writes your fate in here)

---

🌸 DESCRIPTION 🌸

so here's the tea, bestie: this function processes legitimate commands of the Init state — the ones that are actually allowed to be there — and then, conditionally, it sets the next state. like a glow-up pipeline. next state unlocked, slay. 💫

and for everyone else? reject all other commands. not your state, not your command, not today. 🙈 literally the vibe check at the door and it does not miss. 💀

no cap, "conditionally" is doing a lot of heavy lifting in that sentence — she only moves you to the next state when the conditions are right. that's just what the page says, and we respect the page. 🫶
