do_passive_init(9)

💅 do_passive_init(9) — the Kernel API Manual ✨

okay so bestie, welcome to the do_passive_init(9) page, from the Kernel API Manual, no big deal, just a little function that finishes the probe when your partner finally decides to show up 🫶

---

🌸 NAME 🌸

do_passive_init — literally the glow-up that completes probing once the partner device is detected 💖

---

✨ SYNOPSIS ✨

int do_passive_init (struct ibmvnic_adapter *adapter );

---

🎀 ARGUMENTS 🎀

• adapter — the ibmvnic_adapter struct, aka the main character of this whole situation 👑

---

🦋 DESCRIPTION 🦋

okay so picture this: the ibmvnic device boots up and there's no partner device to communicate with 😭 the vibes are off, the partner just isn't there. but then — plot twist — that partner device comes online at a later time 🌈 and that's when this function gets called, to complete the initialization process of the ibmvnic device. slay. it's giving "finishing what we started" energy fr fr 💅

ngl, the caller is expected to hold rtnl_lock 🔒 so like… do that. it's not optional, bestie.

so what does it return? okay:

• returns non-zero if sub-CRQs aren't initialized properly — and that leaves the device in the down state 💀 not iconic, but that's the deal
• returns 0 upon success, and the device is in the PROBED state 👑 periodt
