💅 intel_fb_is_gen12_ccs_aux_plane(9) — the Kernel API Manual page, but make it make sense ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — this page is literally called intel_fb_is...cs_aux_plane(9) (the shell ate some letters, she's shy, iykyk) and it's about one tiny little bool function that answers one very specific question about framebuffers. lowkey iconic if you're into display drivers. no cap. 🦋

✨ NAME ✨

intel_fb_is_gen12_ccs_aux_plane — the way this function checks if a framebuffer color plane is a GEN12 CCS AUX plane, like, that's her whole thing. 💅

🌸 SYNOPSIS 🌸

bool intel_fb_is_gen12_ccs_aux_plane (const struct drm_framebuffer *fb ,
int color_plane );

she's a bool girlie, she takes two args, and she returns an answer. periodt. ⭐

🫶 ARGUMENTS 🫶

  • fb — Framebuffer. yes queen, the framebuffer itself. we're looking at her.
  • color_plane — color plane index to check. like which plane slot we're vibe-checking. 🔍

💖 RETURN 💖

Returns true if fb's color plane at index color_plane is a GEN12 CCS AUX plane. that's it, that's the whole answer. true or nothing bestie 😭 — okay not "nothing", it returns false when it's not, but you knew that. 🎀

🌈 SEE ALSO 🌈

the kernel file where all this lives, for when you want to read the source like the main character you are:

  • ./drivers/gpu/drm/i915/display/intel_fb.c

and her whole friend group, all of them, every single one, not skipping a single bestie:

✨ ngl bestie, if you're deep in the i915 display code at 3am, that whole list is your group chat and intel_fb.c is the pinned message. 💀

aaand that's the page! 🧚 she lives with the rest of ./drivers/gpu/drm/i915/display, she's dated October 2026, and she's filed under intel_fb_is...cs_aux_plane(9) in the Kernel API Manual — go off, kernel docs, we love to see it 💜🔥
