ice_devlink_flash_update(9)

💖 NAME 💖

ice_devlink_flash_update — write a firmware image to the device, bestie 💅

This is straight from the Kernel API Manual, and it's giving "let me flash that firmware for you" energy ✨

---

🌸 SYNOPSIS 🌸

int ice_devlink_flash_update (struct devlink *devlink , struct
       devlink_flash_update_params *params , struct netlink_ext_ack *extack );

---

🎀 ARGUMENTS 🎀

• devlink — pointer to the devlink associated with the device to update 🫶
• params — the devlink flash update parameters, aka the vibe check for this update 💫
• extack — the netlink extended ACK structure, here for the receipts 📝

---

🦋 DESCRIPTION 🦋

Okay so first things first: this function parses the data for a given firmware file, verifying that it is a valid PLDM formatted image that matches this device. Yes, it's doing the "are you who you say you are" check 👀✨

Then it extracts the device record Package Data and Component Tables and sends them to the firmware. Slay, data delivery 💌

It also extracts and writes the flash data for each of the three main flash components: "fw.mgmt", "fw.undi", and "fw.netlist". All three, no skipping, periodt 💅

Finally, it notifies firmware once the data is written to the inactive banks. Like, "hey bestie, we're done writing over here" 📣💖

---

🌈 RETURN 🌈

Zero on success, or a negative error code on failure. That's it, that's the whole mood: 0 means iconic win, negative means something went sideways 😭💀
