✨ drm_rect_intersect(9) ✨

okay so bestie, this is a page from the Kernel API Manual and it's literally just about squishing two rectangles together to see where they overlap 💅 like venn diagram energy but for the kernel, no cap

🌸 NAME 🌸

drm_rect_intersect — intersect two rectangles 🫶

🎀 SYNOPSIS 🎀

bool drm_rect_intersect (struct drm_rect *r1 , const struct drm_rect *r2
);

💖 ARGUMENTS 💖

  • r1 — first rectangle, she's the main character here fr fr (and she's about to get rewritten, spoiler)
  • r2 — second rectangle, the const one, she stays exactly as she is 🌸

🦋 DESCRIPTION 🦋

So the whole vibe is: calculate the intersection of rectangles r1 and r2. That's it. That's the tea ☕

The way that r1 gets overwritten with the intersection — like, not me just casually replacing your rectangle with the overlap, but that is literally the whole function, iykyk 💀

🔥 RETURN 🔥

true if rectangle r1 is still visible after the operation, false otherwise.

so like... if there's still something there to look at, she says true 👑 if the rectangles missed each other entirely and r1 got absolutely ate by the intersection, she says false 😭 vibe check failed, nothing left to see

⭐ SEE ALSO ⭐

kernel file ./drivers/gpu/drm/drm_rect.c — like, the actual file, go read it bestie 🧚

💜 bestie this is genuinely iconic: the rectangles intersect, r1 becomes the overlap, and if r1 is still visible you get true back. that's the entire personality. periodt.

and that's a wrap on the page from ./drivers/gpu/drm, dated October 2026, signed drm_rect_intersect(9) — slay, go intersect some rectangles 💅✨🎀
