rio_enum_mport(9)

Hey bestie, welcome to the rio_enum_mport(9) page from the Kernel API Manual — it’s giving kernel-core energy and we’re gonna understand it fr fr. 💖

🎀 NAME 🎀

rio_enum_mport — Start enumeration through a master port. Slay.

✨ SYNOPSIS ✨

int rio_enum_mport (struct rio_mport *mport , u32 flags );

💅 ARGUMENTS 💅

• mport — Master port to send transactions. This is the main-character port doing the sending. 👑
• flags — Enumeration control flags. Little control knobs, iconic.

🌈 DESCRIPTION 🌈

Okay so this function starts the enumeration process. If somebody has enumerated our master port device, then it gives up — not me showing up late to a group project that’s already done, honestly. 😭

If that hasn’t happened, and we have an active link, then it starts recursive peer enumeration. Recursive peer vibes, we love to see it. 🦋

Returns 0 if enumeration succeeds or -EBUSY if enumeration fails. No cap.
