DEVICE_SET_DRIVER(9)

💖 DEVICE_SET_DRIVER 💖

okay bestie, welcome to the Kernel Developer's Manual, section 9 — yes we're deep in kernel dev territory, this is DEVICE_SET_DRIVER(9) and she's short, sweet, and lowkey powerful 💅

✨ NAME ✨

device_set_driver — the girl who introduces a specific driver to a device node in the tree 🫶 like a matchmaker but for kernel objects

🌸 SYNOPSIS 🌸

#include <sys/param.h>
#include <sys/bus.h>

void
device_set_driver(device_t dev, driver_t *driver);

no cap, that's the whole thing. two includes, one function, zero drama ✨

🦋 DESCRIPTION 🦋

so what does she even do? device_set_driver associates a specific driver with a given device node in the tree. that's it. that's the whole vibe. iconic behavior honestly 💖

the way it's normally used is inside DEVICE_IDENTIFY(9) functions, to add devices to a bus that does not support doing that automatically — like, for example, the ISA bus 🙈 she's old school like that, and we respect her for it.

ngl this is the manual-page equivalent of sliding into someone's DMs to say "hey you two should totally know each other" 🎀
