💅 __drm_atomic_helper_plane_reset — the Kernel API Manual glow-up 🎀

okay so bestie, welcome to the Kernel API Manual entry for __drm_atomi..._plane_reset(9) — yes the title got truncated by the terminal, no it's not a glitch, it's just living its best abbreviated life 💖

✨ NAME ✨

__drm_atomic_helper_plane_reset — reset state on plane 🦋

✨ SYNOPSIS ✨

void __drm_atomic_helper_plane_reset (struct drm_plane *plane , struct
drm_plane_state *plane_state );

✨ ARGUMENTS ✨

  • plane — the drm plane, your main character 🎀
  • plane_state — the plane state you're gonna assign. hand it over, bestie 🫶

✨ DESCRIPTION ✨

so what this does is it initializes that freshly-allocated plane_state and then assigns it straight to the drm_plane->state pointer of plane. lowkey iconic ✨

when do you need it? usually when you're initializing the drivers, or when it gets called from the drm_plane_funcs.reset hook. iykyk 💅

and the whole point — the reason this exists at all — is that it's useful for drivers that subclass the plane state. like, if you're doing the fancy custom-struct thing, this is your girl 🔥

🌈 SEE ALSO 🌈

grab a snack because this list is long and honestly it ate 🍓

ngl the whole plane / crtc / connector / bridge family is giving "one big friend group" energy and this function is literally just the plane one's reset moment. go read the neighbours, they all slay 💜
