clkdm_wakeup(9)

💖 clkdm_wakeup(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this little page is all about clkdm_wakeup(9), and honestly? she's a tiny function with main character energy 👑

---

🌸 NAME 🌸

clkdm_wakeup — force clockdomain wakeup transition ⚡

---

🦋 SYNOPSIS 🦋

int clkdm_wakeup (struct clockdomain *clkdm );

---

🎀 ARGUMENTS 🎀

• clkdm — a struct clockdomain *, literally just a pointer to the clockdomain you're trying to wake up 🫶

---

💅 DESCRIPTION 💅

So the way this works is: you tell the CM to force a wakeup transition on the clockdomain you passed in as clkdm. That's it, that's the whole vibe 🔥

Now for the receipts (no cap, read these):

• Returns -EINVAL if clkdm is NULL 😭 or if the clockdomain does not support software-controlled wakeup 🙈
• Returns 0 upon success ✅

bestie pls check your pointer before you call this — a NULL is not gonna slay here 💀
