MAX_PLANES(9)

✨ MAX_PLANES — kernel API manual, section 9 ✨

okay so bestie, welcome to MAX_PLANES(9) 💅 this is a tiny little page from the Kernel API Manual and honestly? it's giving "small but iconic". let's get into it 🫶

🌸 NAME 🌸

MAX_PLANES — literally the representative of the upper bound of planes that are supported by the HW 💖

like, it's the vibe-check number for how many planes the hardware can handle, no cap. the HW sets the ceiling, MAX_PLANES is the girl holding the clipboard saying "that's the max, periodt" 👑

🎀 SYNOPSIS 🎀

MAX_PLANES

that's it. that's the whole synopsis. she's a single identifier and she knows it ✨ not me being obsessed with a macro-ish constant that has zero arguments 😭

🦋 SEE ALSO 🦋

okay so this is the part where the page goes full group-chat-tagging-everyone energy 💀 like, MAX_PLANES does NOT show up alone, she brings her whole friend group. every single one of these, in order, bestie:

fr fr go read those too if you wanna understand the whole display-core situation — MAX_PLANES is literally just the upper-bound girlie in a much bigger friend group 💜

and that's the page!! short, sweet, and honestly kind of a serve 🌸 this little queen lives at ./drivers/gpu/drm/amd/display/dc and the date on her birth certificate says October 2026 — mwah, go touch some planes (the hardware kind, not the airport kind) ✈️💖🎀
