ixgbe_aci_read_nvm(9)

💅 ixgbe_aci_read_nvm(9) — like, the NVM-reading girlie ✨

okay so bestie, welcome to the Kernel API Manual and today's main character is ixgbe_aci_read_nvm 💖 she's a little function with one job and she does it immaculately. the whole thing is about reading NVM, and yes we're gonna get into it 🫶

---

🌸 NAME 🌸

ixgbe_aci_read_nvm — read NVM 📖✨

literally that's it. read NVM. iconic, concise, no notes 👑

---

🦋 SYNOPSIS 🦋

int ixgbe_aci_read_nvm (struct ixgbe_hw *hw , u16 module_typeid , u32
offset , u16 length , void *data , bool last_command , bool
read_shadow_ram );

seven arguments, one int coming back at you, and she ate 💅

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW struct 🧸 like, the hardware context, the whole vibe, you need her.
• module_typeid — module pointer location in words from the NVM beginning ✨ (words, bestie, not bytes — note it).
• offset — byte offset from the module beginning 📏 relative to wherever the module starts.
• length — length of the section to be read (in bytes from the offset) 🌸 how much we're grabbing, counted in bytes, starting from offset.
• data — command buffer (size [bytes] = length) 💾 so the buffer gotta be length bytes big, fr fr, do not undersize her 🙈
• last_command — tells if this is the last command in a series 🏁 like, "bestie this is the finale" for a batch of commands.
• read_shadow_ram — tell if this is a shadow RAM read 👻 exactly what it sounds like, the shadow RAM flag.

---

⭐ DESCRIPTION ⭐

Read the NVM using ACI command (0x0701) 🔥 that's the whole description, she's lowkey mysterious but the hex is right there: 0x0701. write it down, iykyk 💜

---

🌈 RETURN 🌈

the exit code of the operation 💫 so like, check her return value, bestie — she's telling you how it went.

that's the whole roster, bestie. go read 'em. every single one of them. 💀✨

ngl this page is short but she's doing the work — that 0x0701 is the moment, the whole ACI command, the main character energy 🌟

and that's the page 🎀 this lil beauty comes from ./drivers/net/ethernet/intel/i... (yeah the path got cut off in the footer, that's literally what it says, don't come for me 🙈), dated October 2026, and the footer signs off with ixgbe_aci_read_nvm(9) one more time for the people in the back 💜 bye bestie, go read that NVM 🦋🍓
