💅 intel_fb_rc_ccs_cc_plane(9) — bestie's guide to the CCS CC color plane index

okay so real talk, this is a page from the Kernel API Manual (the intel_fb_rc_ccs_cc_plane(9) one, yes the name is a mouthful, iykyk 🫶) and honestly? it's short. it's giving "one job, does it well" energy. let's get into it ✨

🌸 NAME 🌸

intel_fb_rc_ccs_cc_plane — literally just: get the CCS CC color plane index for a framebuffer 💅

---

⭐ SYNOPSIS ⭐

int intel_fb_rc_ccs_cc_plane (const struct drm_framebuffer *fb );

---

🎀 ARGUMENTS 🎀

• fb — the framebuffer. that's it. that's the whole argument. iconic minimalism, no notes 🌈

---

🔥 RETURN 🔥

it returns the index of the color clear plane for fb 💖

...or -1 if fb is not a framebuffer using a render compression/color clear modifier. so like, no modifier match, no plane index, we return negative one and move on. periodt. 💀

ngl bestie, if you were looking for drama, this manpage is not it — one arg, one return, one -1 for the modifier mismatch case. but it's your -1 and it's valid 🥺

that's the whole vibe ✨ this page ships out of ./drivers/gpu/drm/i915/display, October 2026 edition — mwah, go touch some registers 💜
