BUS_GENERIC_NEW_PASS(9)

📦 version 15.1, in freebsd 14.5, freebsd 15.1, nixpkgs unstable

🌸 NAME 🌸

okay bestie, welcome to the Kernel Developer's Manual entry for BUS_GENERIC_NEW_PASS(9) 💅

bus_generic_new_pass — the generic implementation of BUS_NEW_PASS for bus devices, no cap ✨

✨ SYNOPSIS ✨

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

void
bus_generic_new_pass(device_t dev);

💖 DESCRIPTION 💖

This function is literally giving bus drivers an implementation of the BUS_NEW_PASS(9) method 🫶

First, it invokes the DEVICE_IDENTIFY(9) method for any drivers whose pass level is equal to the new pass level. Then, for each attached child device, it calls BUS_NEW_PASS(9) to rescan child buses 💅 and for each unattached child device, it calls device_probe_and_attach(9). Periodt 🌟

bestie, it’s a whole little pass-level pipeline: identify the matching drivers, rescan the attached children, then probe-and-attach the unattached ones 🔥
