xe_guc_pc_re...stashed_freq(9)

💖 NAME 💖

xe_guc_pc_restore_stashed_freq — bestie, this one just sets min/max back to the stashed values ✨

So like, this is a page straight out of the Kernel API Manual, and it's all about one lil' function that does exactly one lil' thing: it takes the min and max frequencies you had tucked away in your stash and puts them right back where they belong. No cap. 🎀

---

✨ SYNOPSIS ✨

int xe_guc_pc_restore_stashed_freq (struct xe_guc_pc *pc );

That's it, that's the whole vibe check — it takes a pointer to a struct xe_guc_pc and hands you back an int. 🦋

---

🌸 ARGUMENTS 🌸

• pc — The GuC PC. That's your GuC Power Conservation thingy, the main character of this whole operation 👑

---

⭐ RETURN ⭐

• 0 on success 🥳
• an error code on failure 😭 (iykyk, always check your return values, bestie)
