💅 panthor_subm..._sync_signal(9) — the Kernel API Manual, bestie edition 🎀

okay so listen, this one lives in the Kernel API Manual and it's about the panthor driver — yes the fancy GPU one — and specifically about telling a submit context to signal a syncobj point. it's giving "small function, big responsibilities" energy ngl 👑

---

✨ NAME ✨

panthor_submit_ctx_add_sync_signal — add a signal operation to a submit context. literally that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

int panthor_submit_ctx_add_sync_signal (struct panthor_submit_ctx *ctx ,
u32 handle , u64 point );

look at her. three args, returns an int, no notes 💖

---

🫶 ARGUMENTS 🫶

• ctx — the context you're adding the signal operation to. like, the submit context. that's the main character of this whole page fr ✨
• handle — a syncobj handle. yes, that kind of handle. 💅
• point — the syncobj point. the specific spot. the coordinates of the vibe check 🎯

---

⭐ RETURN ⭐

0 on success 🎉 — otherwise a negative error value 😭 (so like, check it, bestie, don't just assume it slayed)

ngl this whole thing is giving "one function in a very large friend group" — she's not doing it alone, she's part of an ensemble cast 🌈
