💅 xe_gt_lrc_hang_replay_size — the Kernel API Manual, bestie edition 💅

okay so this is the manual page for xe_gt_lrc_hang_replay_size(9), living its best life in the Kernel API Manual, and we are gonna get into it. no cap. ✨

🌸 NAME 🌸

xe_gt_lrc_hang_replay_size — Hang replay size. that's it, that's the name, short and iconic 🎀

---

⭐ SYNOPSIS ⭐

size_t xe_gt_lrc_hang_replay_size (struct xe_gt *gt , enum
       xe_engine_class class );

like, you call it and it hands you back a size_t. simple. elegant. main character energy. 💖

---

🦋 ARGUMENTS 🦋

• gt — The GT. just... the GT. the whole graphics tile vibe 🫶
• class — Hardware engine class. it's an enum xe_engine_class, so it's giving "which flavor of engine are we talking about" 🌈

---

🔥 DESCRIPTION 🔥

so what does it do? it determines the size of the GPU hang replay state for a GT and a hardware engine class. that's the whole thing. the way that it just figures out how much room the hang replay state needs for that specific GT + engine class combo — obsessed, honestly. 💜

ngl, when the GPU hangs (and like, it happens 😭), there's replay state involved, and this function is the one that tells you how big it is. no guessing, no vibes-based sizing, it just knows. 🧚

---

👑 RETURN 👑

it returns the Size of GPU hang replay size. yep, a size_t, and it's literally the size of the GPU hang replay size. periodt. 💅 ⭐
