panthor_vm_...repare_resvs(9)

💅 panthor_vm_bind_job_prepare_resvs — the "get your resvs ready bestie" function

okay so real talk, this is a page straight out of the Kernel API Manual for panthor_vm_...repare_resvs(9) — yes that's the truncated title, she's shy, it's fine. Anyway. Grab a boba, we're locking some reservations together 🧚✨

---

✨ NAME ✨

panthor_vm_bind_job_prepare_resvs — literally the function that prepares the VM_BIND job's dma_resvs. no cap, that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int panthor_vm_bind_job_prepare_resvs (struct drm_exec *exec , struct
       drm_sched_job *sched_job );

---

🦋 ARGUMENTS 🦋

• exec — the locking/preparation context. think of it as the little makeup bag where all the locking state lives 💄
• sched_job — the job you're preparing resvs on. she's the main character here 👑

---

💖 DESCRIPTION 💖

So what does she do? She locks and prepares the VM resv. That's it, that's the job. ✨

And — plot twist — if this is a map operation, she also locks and prepares the GEM resv. iykyk. 🔥

---

⭐ RETURN ⭐

• 0 on success 🎉
• a negative error code otherwise 😭 (yes, negative. it's giving "something went wrong", read the code and find out which)
