rio_init_em(9)

🦋 rio_init_em(9) 🦋

okay so welcome to the Kernel API Manual, bestie — this is the page for rio_init_em(9), and it's giving “small but important switch setup energy.” 💅

---

✨ NAME ✨

rio_init_em — Initializes RIO Error Management (for switches)

---

🌸 SYNOPSIS 🌸

void rio_init_em (struct rio_dev *rdev );

---

🎀 ARGUMENTS 🎀

• rdev — RIO device. That's the device being passed in, bestie. 🫶

---

💖 DESCRIPTION 💖

For each enumerated switch, call the device-specific error management initialization routine — but only if the switch driver actually supplied one. No cap, that's the whole vibe: switches get their error-management init handled when they're enumerated, assuming their driver has a routine for it. ✨
