DEVICE_GET_SYSCTL(9)

💅 DEVICE_GET_SYSCTL(9) — Kernel Developer's Manual, but make it group-chat ✨

okay so bestie, welcome to the DEVICE_GET_SYSCTL(9) page — it's giving kernel developer realness, and we're gonna talk about the sysctl oid tree for driver specific sysctl nodes. no cap. 🫶

🌸 NAME 🌸

device_get_sysctl_ctx, device_get_sysctl_tree — manipulate the sysctl oid tree for driver specific sysctl nodes. 💖

✨ SYNOPSIS ✨

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

struct sysctl_ctx_list *
device_get_sysctl_ctx(device_t dev);

struct sysctl_oid *
device_get_sysctl_tree(device_t dev);

🦋 DESCRIPTION 🦋

The newbus system is literally doing the most: it automatically adds a sysctl node for each device in the system. 🎀

You can access that node with the device_get_sysctl_tree() function. 🌟

The context for the node can be obtained with the device_get_sysctl_ctx() function. 💅

iykyk: these two are your besties for getting at the node and its context, fr fr. 🫶
