icc_get(9)

💅 icc_get(9) — the Kernel API Manual glow-up, bestie ✨

Okay so real talk, this is the icc_get(9) man page from the Kernel API Manual and honestly it's way more iconic than it lets on. It's all about grabbing yourself a path handle between two endpoints, and I'm gonna walk you through it like we're texting at 2am. 🫶

🌸 NAME 🌸

icc_get — get a path handle between two endpoints. That's the whole vibe. Lowkey does exactly what it says on the tin. ✨

---

🦋 SYNOPSIS 🦋

struct icc_path * icc_get (struct device *dev , const char *src , const char *dst );

Like, that's the function signature and you should copy it exactly, no cap. 💖

---

🎀 ARGUMENTS 🎀

• dev — device pointer for the consumer device. Basically "who's asking for this path", iykyk.
• src — source node name. The starting point, the main character of the journey. 🌟
• dst — destination node name. Where we're headed, the final boss. 🏁

---

🔥 DESCRIPTION 🔥

So here's the tea: this function will search for a path between two endpoints and return an icc_path handle on success. That's it, that's the whole move. 💅

⚠️ Bestie, listen: use icc_put to release constraints when they are not needed anymore. Don't just leave them hanging, it's giving clingy ex energy and the kernel will Not be amused. 😭

---

👑 RETURN 👑

• Returns an icc_path pointer on success. Slay. 🎉
• Returns ERR_PTR on error. Not slay, but at least it tells you. 💀
• Returns NULL when the API is disabled. It's literally not even available, so don't come for it. 🙈

This lil masterpiece lives in ./drivers/interconnect, and it's dated October 2026 in the kernel docs, so yeah, future vibes. Periodt. 💜✨
