💅 panthor_submit_ctx_get_sync_signal

okay so bestie, welcome to the Kernel API Manual entry for panthor_submit_ctx_get_sync_signal — yes that name is a mouthful, yes it's giving "my parents let me pick my own name" energy, but we're gonna get through it together 🫶

panthor_submit_ctx_get_sync_signal — literally searches for a signal operation and adds one if none was found 💖 (yes, it's a find-or-create situation, iconic behavior honestly)

---

🌸 SYNOPSIS 🌸

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

---

🎀 ARGUMENTS 🎀

• ctx — the context you're searching the signal operation in 🦋 like, this is the whole world this function lives in
• handle — the syncobj handle, no cap
• point — the syncobj point ⭐
