✨ xe_eu_stall_init(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a little function with a big job, and yes it lives in the kernel so we're gonna be normal about it (we're not).

💖 NAME 💖

xe_eu_stall_init — the glow-up moment where we allocate and initialize the GT level EU stall data structure xe_eu_stall_gt inside struct xe_gt. that's it, that's the whole vibe. it's giving "setup era" ✨

---

🎀 SYNOPSIS 🎀

int xe_eu_stall_init (struct xe_gt *gt );

---

🌸 ARGUMENTS 🌸

• gt — the GT that's getting initialized, aka the main character of this call 🫶

---

🦋 RETURN 🦋

zero on success, or a negative error code if it didn't go off 😭 no in-between, no "it's complicated".

lowkey important: zero = slay, negative = nope.
