💅 __drm_atomic_helper_crtc_reset — the unofficial group chat edition

okay so real talk, this is a page from the Kernel API Manual (yes, the Kernel API Manual, we're fancy now ✨) and it's about resetting state on a CRTC. buckle up bestie, it's shorter than you'd think but every word matters 🎀

✨ NAME ✨

__drm_atomic_helper_crtc_reset — reset state on CRTC 🦋

🌸 SYNOPSIS 🌸

void __drm_atomic_helper_crtc_reset (struct drm_crtc *crtc , struct
drm_crtc_state *crtc_state );

💖 ARGUMENTS 💖

  • crtc — the drm CRTC. that's the thing you're resetting, the main character of this whole operation 👑
  • crtc_state — the CRTC state to assign. this is the fresh little state you're handing over 🫶

🔥 DESCRIPTION 🔥

So what does it do? It initializes the newly allocated crtc_state and assigns it to the drm_crtc->state pointer of crtc. literally that's the whole vibe ✨

When do you need it? usually when initializing the drivers, or when it gets called from the drm_crtc_funcs.reset hook. so like, two very real situations ngl.

And why does this exist? it's useful for drivers that subclass the CRTC state 💅 — if your driver is doing the subclass thing, this helper is your bestie fr fr.

lowkey important: this is the double-underscore version, the internal-ish one. it's not doing the full song and dance, it's just doing the init-and-assign part 🎀

🌈 SEE ALSO 🌈

okay this list is long long, but we're not skipping it, we don't do that here 😭 everything gets its moment:

like… crtc, plane, connector, private_obj, bridge — the whole atomic helper family reunion 🧚

anyway that's the page!! go reset some CRTC state, you got this 💜

this little broadcast came from ./drivers/gpu/drm, dated October 2026, and it's filed under __drm_atomic...r_crtc_reset(9) in the Kernel API Manual — bye bestie, drink water 🍓✨
