drm_suballoc_event(9)

✨ drm_suballoc_event — Check if we can stop waiting ✨

okay so bestie, this is drm_suballoc_event, straight out of the Kernel API Manual and honestly it's giving "am I free yet?" energy 🫶 it's the little helper that tells you whether it's worth waiting or whether you can just go ahead and grab your memory. iconic behavior, no cap.

---

🌸 SYNOPSIS 🌸

bool drm_suballoc_event (struct drm_suballoc_manager *sa_manager ,
size_t size , size_t align );

---

💅 ARGUMENTS 💅

• sa_manager — pointer to the sa_manager 👑 like, the manager in question, the main character of the allocation world.
• size — number of bytes we want to allocate. how much memory are we talking, bestie 💖
• align — the alignment we need to match. gotta line up just right ✨

---

🦋 RETURN 🦋

it returns true if either:

• there's a fence we can wait for 🚧, or
• there's enough free memory to satisfy the allocation directly 💸

and it returns false otherwise 🙈 that's it, that's the vibe check.

fr fr, that's the whole deal — true means "you've got options", false means "not yet, babe".
