drm_atomic_helper_shutdown(9)

📦 version 7.3.1, in nixpkgs unstable

💅 drm_atomic_helper_shutdown — like, the whole Kernel API Manual vibe

okay bestie, so this page lives in the Kernel API Manual and it's called drm_atomic_helper_shutdown(9). yes the title and the page name are the same thing, that's just how these pages are, we don't question it 🎀

✨ NAME ✨

drm_atomic_helper_shutdown — shuts down all the CRTCs. all of them. every last one. 🫶

🌸 SYNOPSIS 🌸

void drm_atomic_helper_shutdown (struct drm_device *dev );

🦋 ARGUMENTS 🦋

  • dev — the DRM device in question. that's the one you're shutting down, bestie 💜

🔥 DESCRIPTION 🔥

okay so this one shuts down all CRTC — and it's genuinely useful for driver unloading. like, that's its whole moment, that's its main character energy ✨

but listen, real talk 🫶 — if you're doing shutdown on suspend, you should handle that with drm_atomic_helper_suspend instead. why? because that one also takes a snapshot of the modeset state so it can be restored on resume. drm_atomic_helper_shutdown does not do that, so like… don't come crying to me when your state is gone 🙈

and ngl, this function is lowkey just a convenience wrapper around drm_atomic_helper_disable_all. it's also the atomic version of drm_helper_force_disable_all. slay, iconic, periodt 👑

🌈 SEE ALSO 🌈

like I said. a journey. 💀

k bye bestie, ily, go disable those CRTCs responsibly 🎀✨
