cmdq_pkt_wfe(9)

✨ cmdq_pkt_wfe(9) ✨

okay so bestie, this is a page straight outta the Kernel API Manual — cmdq_pkt_wfe(9), and it is literally the "append wait for event command to the CMDQ packet" girlie. that's the whole NAME vibe. let's get into it 💅

---

🌸 SYNOPSIS 🌸

int cmdq_pkt_wfe (struct cmdq_pkt *pkt , u16 event , bool clear );

yes she takes three args and returns an int. iconic signature, no notes 🫶

---

🎀 ARGUMENTS 🎀

• pkt — the CMDQ packet. this is the packet you're appending onto, the main character of the whole operation 👑
• event — the desired event type to wait for, typed as u16. like, the specific event you're holding out for ✨
• clear — a bool that decides whether the event gets cleared or not after the event arrives. so: clear it, or don't. the choice is yours 🦋

---

⭐ RETURN ⭐

0 for success — slay 🎉 — else the error code is returned. ngl if you see a nonzero value, something went sideways and that code is telling you what 💀

love u, bye!! this one came from ./include/linux/soc/mediatek and it's dated October 2026, so drink some water and read ur kernel headers 🧚
