ok so this is a page from the Kernel API Manual and honestly? it's a whole little vibe check for trace paths. bestie, let's get into it 🫶

---

✨ NAME ✨

coresight_blocks_source — the function that checks whether a connection matches the source of the path, if that connection is bound to a specific source. basically it's the bouncer at the club door of your trace path 🎀

---

🌸 SYNOPSIS 🌸

bool coresight_blocks_source (struct coresight_device *src , struct
       coresight_connection *conn );

---

🦋 ARGUMENTS 🦋

• src — the source device of the trace path, aka the main character of this whole operation 👑
• conn — the connection of one outport, just one little outport doing its thing ✨

---

💖 DESCRIPTION 💖

ok so here's the tea ☕: it returns false if the connection doesn't have a source binded, or if the source of the path matches the source that's binded to the connection.

literally that's it, that's the whole function. no cap 💅
