💖 drm_mode_co...elper_resume(9) 💖

okay so this is a page from the Kernel API Manual, and yes the title got cut off in the middle like a text that was too long for the notification preview 😭 — it's drm_mode_config_helper_resume, bestie, we're talking modeset resume energy today 🎀

---

✨ NAME ✨

drm_mode_config_helper_resume — the modeset resume helper, aka the glow-up moment for your display config after a nap 💅

---

🌸 SYNOPSIS 🌸

int drm_mode_config_helper_resume (struct drm_device *dev );

---

🦋 ARGUMENTS 🦋

• dev — the DRM device. that's it, that's the whole arg. your main character device 👑

---

⭐ DESCRIPTION ⭐

okay so picture this: your modeset side just woke up from its little sleep and needs to get cute again. that's literally this helper's whole job — it takes care of resuming the modeset side for you 🫶

here's the rundown, and it's giving very routine, very slay:

• it calls drm_atomic_helper_resume
• it resumes fbdev, but only if fbdev is actually being used
• it enables output polling, but only if it was initiaized (that's their spelling, not mine, I'm just the messenger 💀)

see also: drm_client_dev_resume and drm_kms_helper_poll_enable — like, go read those too, they're the supporting cast and they ate 🔥

---

🌈 RETURN 🌈

• Zero on success — we love a zero, zero is the win 💖
• a negative error code on error — not the vibe, but at least it's honest 😭

⚠️ real talk though: this is kernel API territory. no guessing, no vibes-based coding — read the actual source, bestie, iykwim 🙈
