💅 _coresight_build_path(9) 💅

okay so bestie, welcome to the Kernel API Manual 😌 this page is literally all about _coresight_build_path(9) — the function that recursively builds a path from a @csdev to a sink ✨ no cap.

🌸 NAME 🌸

_coresight_build_path — recursively build a path from a @csdev to a sink 💖

✨ SYNOPSIS ✨

int _coresight_build_path (struct coresight_device *csdev , struct
       coresight_device *source , struct coresight_device *sink , struct
       coresight_path *path );

🎀 ARGUMENTS 🎀

• csdev — the device to start from. like, your starting point bestie 🫶
• source — the trace source device of the path. the origin story ✨
• sink — the final sink we want in this path. the destination, the main character 👑
• path — the list to add devices to. the group chat where everyone gets added 💅

🦋 DESCRIPTION 🦋

okay so here’s the vibe: the tree of Coresight device is traversed until sink is found 👀 from there, the sink is added to the list along with all the devices that led to that point — and the end result is a list from source to sink. literally the whole glow-up journey 🌈

in that list, the source is the first device and the sink is the last one. periodt 💅 source first, sink last, no cap.
