drm_mode_config_reset(9)

💅 drm_mode_config_reset(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in DRM land, your driver just loaded (or just woke up from a nap, aka resume), and everything is vaguely cursed. this function is your girl. she calls ->reset on everything. no cap.

---

✨ NAME ✨

drm_mode_config_reset — she calls the ->reset callbacks. that's it. that's the whole job. and she ate.

---

🎀 SYNOPSIS 🎀

void drm_mode_config_reset (struct drm_device *dev );

---

🌸 ARGUMENTS 🌸

• dev — the drm device. your main character. give her to the function and she'll do the rest 💖

---

🦋 DESCRIPTION 🦋

okay so this function literally calls all of the crtc's, encoder's and connector's ->reset callback. all of them. the whole squad. nobody gets left out 🙈

drivers can use this in, like, their driver load code or their resume code — anywhere you need to reset hardware and software state together. two birds, one iconic function ✨

⚠️ quick note, bestie, don't skip this one: drm_private_obj structures are expected to be stable across suspend/resume cycles, and drm_mode_config_reset does not affect these structures. so if you were hoping she'd touch those — she won't. she said not my department 💀
