drm_modeset...nterruptible(9)

💜 drm_modeset...nterruptible(9) 💜

ok so this is a page from the Kernel API Manual bestie, and we're talking about drm_modeset_lock_single_interruptible — yes the name is a whole mouthful, the manpage header literally abbreviates it to drm_modeset...nterruptible(9) because even the docs gave up 😭. anyway. it's a DRM modeset locking thing. let's get into it 🎀

---

✨ NAME ✨

drm_modeset_lock_single_interruptible — take a single modeset lock 🫶

like literally just one (1) lock. singular. iconic.

---

🌸 SYNOPSIS 🌸

int drm_modeset_lock_single_interruptible (struct drm_modeset_lock *lock
);

it returns an int, it takes a pointer to a struct drm_modeset_lock named lock, that's the whole vibe ✨

---

🦋 ARGUMENTS 🦋

• lock — the lock to take. that's it. that's the argument. the lock you want. go get it bestie 💅

---

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ — this function behaves exactly like drm_modeset_lock with a NULL context, BUT (and this is the main character detail) it performs interruptible waits.

so like, same energy as drm_modeset_lock with NULL context, but if you're waiting on it, you can be interrupted. no cap. 🙈

it returns 0 on success, or -ERESTARTSYS when interrupted. those are the only two moods. 😭
