drm_exec_retry(9)

💅 drm_exec_retry 💅

okay so this is from the Kernel API Manual, and it’s literally the page for drm_exec_retry. buckle up, bestie 🎀

🦋 NAME 🦋

drm_exec_retry — Unconditionally restart the loop to grab all locks.

---

📜 SYNOPSIS 📜

drm_exec_retry (_exec );

---

🎀 ARGUMENTS 🎀

• _exec — bestie, the original page says -- undescribed --, so that is genuinely all we get. no cap. 🙈

---

✨ DESCRIPTION ✨

okay so drm_exec_retry does one thing and does it loudly: it unconditionally retries the loop to lock all objects. unconditional means no vibe check, no asking twice — it just goes again. 🔁

For consistency, the exec object needs to be newly initialized. like, fresh out the wrapper, periodt. 💅

The __drm_exec_loop check exists to prevent usage outside of an drm_exec_until_all_locked loop.

so yeah — if you’re not inside a drm_exec_until_all_locked loop, don’t try it. the __drm_exec_loop check is there to stop that exact chaos. 😭
