💅 panthor_submit_ctx_init(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes this one's straight out of the kernel, and no, it's not as scary as it sounds, i promise 🫶 we're gonna walk through panthor_submit_ctx_init together, step by step, no cap.

---

✨ NAME ✨

panthor_submit_ctx_init — literally just Initializes a submission context. that's the whole vibe. it sets your submission context up so it's ready to go 🎀

---

🌸 SYNOPSIS 🌸

int panthor_submit_ctx_init (struct panthor_submit_ctx *ctx , struct
       drm_file *file , u32 job_count );

look at her. three args, returns an int, iconic behavior honestly 👑

---

🦋 ARGUMENTS 🦋

• ctx — the submit context you're initializing. this is the main character, you're getting her all set up ✨
• file — the drm_file that this submission happens on. like, which file is this whole thing going down on, yk?
• job_count — how many jobs are gonna get submitted. she needs to know the headcount ahead of time 💅

---

⭐ RETURN ⭐

0 on success, and a negative error code otherwise. so like, zero is the slay outcome, and if you get a negative number back, bestie, something went sideways 😭

ngl, always check the return value. a negative error code is your cue that it did not eat. 💀
