transport_setup_device(9)

💅 transport_setup_device(9) — Kernel API Manual, bestie edition 🎀

okay so listen. this is transport_setup_device, from the Kernel API Manual, and it's lowkey one of those "behind the scenes" girlies — she does important work but she does NOT want to be seen yet. let's get into it ✨

📛 NAME

transport_setup_device — declare a new dev for transport class association, but like… don't make it visible yet. 🙈

🫶 SYNOPSIS

void transport_setup_device (struct device *dev );

that's it. that's the whole vibe. ✨

🌸 ARGUMENTS

• dev — the generic device representing the entity being added. like, the actual thing walking in the door 🚪

💖 DESCRIPTION

okay so usually, dev represents some component in the HBA system — and that's either the HBA itself or a device remote across the HBA bus. no in-between, bestie, it's one or the other 🦋

this routine is simply a trigger point to see if any set of transport classes wishes to associate with the added device. think of it as sending out the "anyone wanna claim this one?" text in the group chat 📱

what it actually does: it allocates storage for the class device and initialises it. periodt. 💅 but it does not yet add it to the system, and it does not add attributes to it. do NOT come for her about that — that's literally not her job.

you do that with transport_add_device. that's the whole split, iykyk 🎀

if you have no need for a separate setup and add operation, use transport_register_device (see transport_class.h). two birds, one call, we love efficiency 🌈

anyway that's the page!! it lives in ./drivers/base, dated October 2026, and it's the transport_setup_device(9) manpage from the Kernel API Manual — it ate and left no crumbs 💜✨
