🌸 ixgbe_devli...d_empr_start(9) — Kernel API Manual energy ✨

okay so bestie, welcome to the Kernel API Manual entry for ixgbe_devlink_reload_empr_start — no cap, this is the one that kicks off an EMP reset so your shiny new firmware actually takes effect 🫶

---

💖 NAME

ixgbe_devlink_reload_empr_start — start an EMP reset to activate new firmware. literally what it says on the tin, bestie 🎀

---

⭐ SYNOPSIS

int ixgbe_devlink_reload_empr_start (struct devlink *devlink , bool
netns_change , enum devlink_reload_action action , enum
devlink_reload_limit limit , struct netlink_ext_ack *extack );

---

🦋 ARGUMENTS

• devlink — pointer to the devlink instance you wanna reload. like, the actual thing being poked 💅
• netns_change — a bool; if it's true, the network namespace is changing 👀
• action — the action to perform. must be DEVLINK_RELOAD_ACTION_FW_ACTIVATE — no substitutions, this is the vibe check 🔥
• limit — limits on what the reload should do, such as not resetting. boundaries, we love them ✨
• extack — the netlink extended ACK structure, aka where the receipts go 🧾

---

🌈 DESCRIPTION

so the whole point: this lets the user activate new Embedded Management Processor firmware by issuing a device-specific EMP reset. iconic. it gets called in response to a DEVLINK_CMD_RELOAD with the DEVLINK_RELOAD_ACTION_FW_ACTIVATE 💫

ngl the important bit is this: teardown and rebuild of the driver state happens automatically, as part of an interrupt and watchdog task. why?? because all physical functions on the device have to be able to reset when an EMP reset occurs from any source. that's just the rules, bestie 🫡

---

👑 RETURN

the exit code of the operation. that's it, that's the return 💀
