eu_stall_data_buf_poll(9)

💅 eu_stall_data_buf_poll(9) — from the Kernel API Manual

okay so bestie, buckle up, because this one is a tiny little function with main character energy ✨ We're in the Kernel API Manual today, and the whole vibe is: "hey, is there anything in the EU stall buffer yet?" That's it. That's the function. Short, sweet, iconic.

---

🌸 NAME 🌸

eu_stall_data_buf_poll — literally just polls for EU stall data in the buffer. That's the whole job. No cap. 💖

---

✨ SYNOPSIS ✨

bool eu_stall_data_buf_poll (struct xe_eu_stall_data_stream *stream );

It hands you back a bool. Truthy or falsy, no in-between, no "it depends", we love a decisive king 👑

---

🎀 ARGUMENTS 🎀

• stream — your xe EU stall data stream instance. Like, the actual stream object you're checking on. It's giving "pass me your whole stream bestie" energy 🦋

---

🔥 RETURN 🔥

• It returns true when the EU stall buffer has at least the minimum stall data, as specified by the event report count.
• Otherwise you get false. Simple as that. Ngl it's the cleanest little yes/no you'll ever get 💅

fr fr, the "minimum" here is decided by the event report count — that's the line in the sand, not me guessing 🙈
