BUS_DELAYED_ATTACH_CHILDREN(9freebsd)

💖 BUS_DELAYED_ATTACH_CHILDREN — the bus_delayed_attach_children(9) girlies know ✨

okay so bestie, welcome to the bus_delayed_attach_children(9) kernel developer's manual page 🎀 this one is short and sweet and honestly iconic for it.

🌸 NAME 🌸

bus_delayed_attach_children — no cap, this is the "hey can u pls attach my children when interrupts are on" request 💅

✨ SYNOPSIS ✨

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

int
bus_delayed_attach_children(device_t dev);

look at that signature. chef's kiss. two includes, one function, zero drama 🦋

💜 DESCRIPTION 💜

so bus_delayed_attach_children() is literally asking for the children of this device to get attached while interrupts are running, fr fr.

here's the tea tho, and it depends on timing:

• if interrupts are currently running, it happens immediately ⚡
• if interrupts aren't running yet, it happens after interrupts are enabled, but before the system mounts root 🌱

that's the whole vibe. not me being obsessed with a two-branch conditional 😭

👑 RETURN VALUES 👑

a zero return value means success. that's it, that's the return value section, periodt ✨

🌈 SEE ALSO 🌈

• bus(9)
• device(9)
• driver(9)

go read those too bestie, iykyk 🫶
